U01 Studies of the Inner Core: New Challenges
Recent observational and theoretical studies reveal major insights
into the structure of the Earth's core and the dynamics at the center of
the Earth but also pose new challenges. The progress was made at many fronts,
including Geochemistry, Geodesy, Geomagnetism, Seismology, and Tectonophysics.
This session will provide an interdisciplinary forum for presenting recent
results and debates on the Earth's core. Topics include constraints on
rotation of the inner core, fine structure of the inner core and influence
of the mantle, theoretical and laboratory constraints on mineral properties
at core conditions, geodynamo, core composition and formation, major and
trace element partitioning during core crystallization, and interactions
between the core and mantle.

U02 Geophysics in the 20th Century: Contributions
from Washington
In 1900, large-scale, systematic and institutionalized research in
Geophysics did not exist. By the end of the 20th century this had become
the main model not only for geophysical research but essentially all of
scientific research. This special session --held on the occasion of the
100th anniversary of the founding of the Carnegie Institution of Washington
(CIW) -- will explore the historical legacies and interagency linkages
which have contributed to the development of the geophysical sciences in
the Washington, DC area over the last 100 years. The nation's capital plays
a unique role as host to more organizations dedicated to some aspect of
geophysical research (such as AAAS, American Geological Institute, AGU,
CIW, Defense Mapping Agency, Geological Society of Washington, IRIS, JOI,
Mineralogical Society of America, NASA, NIST, Naval Observatory, NOAA,
Naval Research Lab, NSF, Smithsonian Institution, and USGS) than any other
locale in the world. Contributions to this session are sought that will
highlight the role of the Washington scientific community in the growth
of Geophysics.

U03 Sustainability of fresh water, fossil fuels,
minerals, and other earth resources: how much, how deep, how expensive,
and how certain?
Sustainable development with finite supplies of fresh water, fossil
fuels, and many other resources poses huge challenges for earth science.
How much fresh water, petroleum, coal, copper, etc. exists, and where?
What will it take to extract these resources, and at what environmental
cost? What is the fate of the expended resources and their by-products?
What materials will replace the exhausted ones, and what is their future?
Will we have the metals and other resources to develop alternatives to
fossil fuels when the time comes? What are the uncertainties in our projections
of future supply and costs? What new technologies may answer these questions?
What basic scientific problems must be solved to improve resource management
on national and global scales? How can scientists, economists, and policy
makers collaborate to preserve the life-support systems of planet Earth?

U04 Ice Sheets, Neotectonics, and Sea-level Change
The Earth's response to past and present ice mass changes includes
three-dimensional crustal motion and changes to sea level, the gravitational
field, and mantle and lithospheric stress. In turn, ice sheet growth and
stability is affected by the Earth's response because crustal subsidence
affects the location of the grounding line and the height of the ice sheet.
This session seeks contributions examining cryosphere-lithosphere interactions.
Topics include, but are not limited to: discussions of new data or compilations
related to present ice mass balance and past ice mass evolution; recent
advances in glaciological modelling of ice sheet inception, growth, and
decay, in particular the controls that isostasy may exert on the life cycle
of an ice sheet; recent progress in glacio-isostatic modelling, including
analysis of new data-sets bearing on glacio-isostasy, new numerical and
analytical techniques, and investigations of the effects of lateral crustal
heterogeneity; and studies of interactions between ice sheet change, crustal
stress, and seismicity. Contributions related to Antarctic neotectonics
- its ice sheet history and present balance, the ensuing glacio-isostatic
response, including crustal motion and sea-level change, and patterns of
seismicity and their relation to ice sheet balance - are especially welcomed.

U05 Integrating Climate Research, Applications,
and Assessment
Climate research is advancing our understanding of not only mechanisms
of climate change and variability, but also interactions among climatic,
ecological, and social systems. Climate scientists are increasingly challenged
to apply their knowledge to predictive analysis of policy response options.
Assessments are being conducted to synthesize advances in climate research
and applications, and to evaluate the relevance of these advances to societal
concerns. New forms of discourse are being explored among scientists, stakeholders,
decision-makers, and citizens concerned with problems such as prioritizing
key regional issues, characterizing relevant uncertainties, and assessing
potential responses. A principal challenge now is to develop these discussions
into ongoing strategies for integration of assessment findings into research
planning and applications development. Speakers in this session will focus
on the following themes: - Climate inputs for impact assessments - Response
of ecological and social systems to climate - Development of assessment
methods - Building regional and local capacity for understanding and response
- Integration in government-funded programs Invited and submitted papers
should address the challenges and implications of integration from both
research and societal perspectives.

U06 Geophysics and Terrorism
The new global priority to fight terrorism will involve, directly and
indirectly, geophysicists and data and knowledge produced by the research
community. In one sense, the geoscience community is strongly positioned
to serve as the technological equivalent of a `global' neighborhood watch
program through the wide variety of environmental sensors and networks
that monitor the Earth, oceans, atmosphere, and space. This session will
consist of invited and contributed talks that discuss how current Earth
and space science research and environmental monitoring is applicable and
important to the broader societal goal of combating global terrorism. Topics
and themes will include, but are not limited to, seismology, watershed
monitoring and water resource infrastructure, plume migration at all scales
in the hydrosphere and atmosphere, weather forecasting for military and
counterrorism applications, space weather, and parameters relevant to understanding
and protecting against bioterrorism.

A01 In Honor of Robert de Zafra's 70th Birthday
Bob de Zafra will be turning 70 years old this year. He has been a
pioneer in ground-based microwave measurements of the stratosphere. His
contributions go beyond just his own personal science. Many of the scientists
doing experimental, analytical, and modeling studies of the stratosphere
studied under Bob. We invite papers on how knowledge gained by ground-based
remote sensing measurements of the middle atmosphere have helped advance
our knowledge of stratospheric behavior. We also solicit contributions
on contemporary investigations using ground-based remote sensing measurements
to study the middle atmosphere.

A02 Seventeen Years of SAGE II Data
On October 5, 2001, the Stratospheric Aerosol and Gas Experiment (SAGE
II) passed the 17th anniversary of its launch aboard the Earth Radiation
Budget Experiment. During this period, SAGE II data has significantly contributed
to understanding trends and variability of ozone in the stratosphere and
the long-term variability of aerosol including the 1991 eruption of Mt.
Pinatubo and the recent clean period. This session will focus on the recently
released Version 6.1 including algorithms, validation, and comparisons
with other platforms. In addition, applications of the new data set to
understanding ozone and aerosol variability and other science applications
will be addressed.

A03 Atmospheric Impacts of Urban Air Pollution
Anthropogenic activities emit gaseous and particulate compounds into
the atmosphere that significantly alter the air compositions on the urban
scale. Recent studies have suggested that the changes in the atmospheric
chemical compositions lead to changes in cloud microphysical and electrical
properties. For instance, elevated aerosol concentrations may suppress
the warm-rain process and enhance lightning. This session is intended to
provide a forum for discussions of the potential impacts of human activities
on the urban atmosphere. Papers are invited to assess the physical and
chemical impacts of urban air pollution, on the basis of field, modeling,
or laboratory studies.

A04 Upper-Air Temperature Data Products for Climate
Studies: Methods, Products, and Challenges
Changes in the atmospheric temperature profile are thought to be an
important indication of climate change, and their vertical structure provides
clues regarding the attribution of the changes to natural or forced variability.
Detecting such changes requires high quality, continuous data records that
are relatively free of artificial signals, such as those associated with
instrument drift or changes in observing systems. Recent controversy regarding
differences in temperature trends from different datasets has motivated
research efforts to create improved multi-decadal datasets. Creation of
homogeneous, global upper-air temperature data records from satellites
and radiosondes is challenging due to lack of reference temperature time
series and a wide assortment of data sampling and quality issues. Papers
dealing with the following topics are encouraged: methods used to quality
control data, combine data from different observing systems, and remove
artificial discontinuities; new climate data records for upper-air temperature;
comparisons among different data products; associated uncertainties in
upper-air temperature trends; challenges of creating historical data products
from archived data; improvements in future observing systems to facilitate
more reliable trend analysis.

A05 Organic Aerosols in Past and Present Atmospheres
Organic aerosols are a very active area of research, with many laboratory
and field measurements being performed, some with new techniques such as
laser mass spectrometry and Time of Flight-Secondary Ion Mass Spectrometry
which are revolutionsing our understanding. We seek papers in these areas
of laboratory and field measurement of organic aerosols, and also contributions
from those interested in the role of organic aerosols in the origin of
life and in the laboratory synthesis of life.

A06 The Exchange of Chemically Reactive Trace Constituents
between Biosphere and Atmosphere
In this session the exchange of highly reactive trace species like
ozone, nitric oxide, nitrogen dioxide, some volatile organic compounds
(VOC), etc. between tall vegetation canopies and the atmosphere is to be
considered. Furthermore, segregation effects owing to turbulence should
also be elucidated.

A07 From Rain Gage to RANET to Radio: How Information
Technology is Transforming Forecast Communication
Just as super-computing and network capacity have revolutionized the
production of climate and weather information, technology is transforming
the way this information is communicated and used. Innovative networks
of old and new technology from satellite to internet to radio are delivering
climate and weather information to high-tech farms in the U.S. and nomadic
herders in Africa. Papers are sought that describe how climate information
networks are designed to meet the needs of a wide range of users and how
new options for forecast delivery and use are, in turn, influencing the
production of climate information itself.

A08 AERONET: Aerosol Observations, Related Investigations
and Synergism
AERONET is an established internationally collaborative program of
over 120 globally distributed ground-based sites measuring spectral direct
solar irradiance and directional sky radiance. Owing to significant advances
in inversion retrieval algorithms, data availability and measurement accuracy,
a broad scientific community has investigated aerosol optical properties,
validated satellite aerosol retrievals, and participated in numerous multisensor
field campaigns. We solicit papers addressing all aspects of AERONET associated
research including observed aerosol optical properties, radiative forcing,
synergism with satellite observations, aerosol climatology, aerosol models,
validation, aerosol polarization effects, aerosol effects on public health
and other associated research. We also welcome non-AERONET contributions
from other studies of the optical properties of aerosols from airborne
or ground-based instruments.

A12 Physics and Chemistry Near the Tropical Tropopause
The transition from troposphere to stratosphere in the tropics has
come to be understood as a gradual one, rather than a sudden change at
a sharp material boundary. This applies to thermodynamic, chemical, dynamical,
and radiative properties. Mechanisms that are important in either the troposphere
or stratosphere may interact in novel ways in this poorly observed and
understood region, spanning at least from 14 to 19 km. Most stratospheric
air is believed to be processed through this region. This frontier region
may also be significant as a proving ground for theories or models of processes
that have so far been validated only in the main troposphere or stratosphere
where the processes are most obvious. We solicit papers that explore the
properties and physical and chemical processes near the tropical tropopause.
This includes studies of dynamical mixing, gravity and kelvin waves, convection,
thin cirrus clouds, dehydration and chemistry, and/or radiative transfer
near the tropopause, or mechanisms that connect the tropical upper troposphere
and lower stratosphere.

A13 Non-equilibrium Phenomena in Open Geophysical
Systems
This session will focus on recent research on non-equilibrium processes
and dissipative phenomena in open geophysical systems. Dissipative structures
and related fractal scaling, which often appear in non-equilibrium systems,
are recognized features of a number of geophysical systems, and have applications
in weather forecasting, climate characterization and prediction, anthroprogenetic
changes in the atmosphere, and many more. We will address these issues
by attracting papers on the global and local structures of geophysical
fluids, the evolution of open systems, transport properties and scaling
of turbulence,and energetics of the non-equilibrium systems. These include
dissipative and evolutionary properties of the atmosphere and ocean, as
well as mantle convection, long-range structures and correlations in earthquake
fault systems, and extreme properties in the complex geophysical and extra-planetary
geophysical fields.

A14 Variability of Storm Tracks
Recent analyses of storm track variability by several groups have suggested
that the Northern Hemisphere storm tracks have undergone significant interdecadal
variability during the past few decades, and the storm track intensity
may have been on an upward trend since the 1960s. The strength of storm
tracks have clear implications on local climate over the mid-latitudes,
as well as hemispheric impact on the energy and hydrological cycle. Better
diagnoses and understanding of this phenomenon would have significant implications
on our understanding of climate variability and change.

A15 Midlatitude Stratospheric Ozone Loss: Understanding
the Effects of Chemistry and Dynamics
Some researchers consider chemical reactions arising from anthropogenic
compounds as a viable mechanism to explain observed midlatitude stratospheric
ozone loss. Others find evidence for a strong dynamical component, arising
in part from climate change issues. This session seeks papers discussing
attempts to quantify the chemical and dynamical contributions to midlatitude
ozone loss.

A16 Wet and Dry Atmospheric Deposition: Scientific
Advances and Policy Developments
The understanding of the chemistry, physics, and biosphere-atmosphere
interactions of atmospheric deposition, both wet and dry, is improving
through modeling studies and observational programs. Nationwide wet and
dry deposition monitoring networks have been in operation long enough to
have developed an understanding of deposition, along with an understanding
of its variation in time and space. These advances, and the push by Congress
and the Administration for more cost-effective means of pollution control
are driving policy changes that could have major implications for the industrial
community and the environment. This session will explore both scientific
advances and policy developments in the field of atmospheric deposition.

A17 Ice Cores: Glaciology and Environmental Change
Variations in the physical, biological, and chemical or isotopic content
through layered snow and ice can provide substantial insight into past
environmental conditions and climate variability. Extension of these site-specific
records via satellite- or ground-based studies establishes their broader
significance. Retrieval and analysis of these signals has led to significant
advances in understanding the role of the cryosphere in global climate.
In this session, we encourage submission of studies that pursue understanding
of dynamic glaciologic problems as well as detectable natural and anthropogenic
changes in climate conditions. We encourage submissions that link these
studies to glaciologic modeling, remote sensing, oceanography, hydrology,
and atmospheric science as this will facilitate the development of a broad
earth system context. Both oral and poster presentations are welcome.

A18 Observations and Retrievals of the Ocean Surface
Radiation Field and Aerosols Using Field Campaign Data including the Chesapeake
Lighthouse and Aircraft Measurements for Satellites (CLAMS) Experiment
The Chesapeake Lighthouse and Aircraft Measurements for Satellites
(CLAMS) field experiment (10 July -2 August, 2001) targeted atmospheric
aerosols and the radiation field at the sea surface under cloud free conditions.
The emphasis was on the validation and improvement of satellite retrievals
of aerosols, aerosol radiative forcing to climate, and ocean optics boundary
conditions. Data was collected at the Chesapeake Lighthouse ("COVE") sea
platform 15 miles off the coast of Virginia Beach, from coastal stations,
and from a variety of aircraft and satellite sensors. NOAA buoys further
out at sea provided additional information on sea conditions. CLAMS participants
included members of NASA's EOS CERES, MISR and MODIS science teams and
the Global Aerosol Climatology Project (GACP), as well as six universities.
The intent of this special session is to report CLAMS and related science
results and to introduce the CLAMS data base to a wider community of atmospheric,
ocean and remote sensing scientists.

A19 Policy-Relevant vs. Policy-Driven Atmospheric
Chemistry Research: what role do policy applications play in determining
questions, methods, and funding?
We invite members of atmospheric chemistry and policy communities to
discuss how policy applications affect scientific research on air quality.
Session participants are encouraged to address questions such as: (1) When
do funding priorities shape the science, and when do the scientific questions
shape funding priorities? (2) How do agencies who need scientific information
use policy-driven studies versus external research with varying degrees
of policy-relevance? (3) How have scientists adapted their research goals
or program structures to meet the needs of the policy community?

B01 Effects of Land Use on Net Primary Production
of Terrestrial Ecosystems
The productivity of terrestrial ecosystems is a key determinant of
the net exchange of carbon dioxide (CO2) between terrestrial ecosystems
and the atmosphere, and hence atmospheric CO2 concentration. It is also
the primary source of food and other resources for humans and other species.
Humans have altered the productivity of terrestrial ecosystems by changing
the climate, atmospheric chemistry, land use, and age structure of forests.
The objective of the session will be to use empirical field studies, data
synthesis activities, and process models to examine the effects of the
various land use changes on net primary production of terrestrial ecosystems.
Spatial scales can range from case studies to global synthesis, with an
attempt to obtain a balanced coverage of all the major terrestrial ecosystems.
Participants are strongly encouraged to place their results into a larger
context, such as expressing their results relative to effects of elevated
CO2 on NPP.

B02 Biogeochemistry and Conservation Biology
This session focuses on the connections between Biogeochemistry and
Conservation Biology and the relationships of these connections to environmental
policy. Biogeochemistry and Conservation Biology are currently the locus
of much research involving land use and climate change impacts. However,
to a large extent they have remained conceptually and practically separate.
Speakers will address the links among some of the classical issues in these
fields and the opportunities for each discipline to inform the other. In
particular, there will be an emphasis on the links between biological diversity
and biogeochemical processes. Recent advances in the direct and remote
assessment of diversity and in the measurement of biogeochemical processes
will be discussed. The session will also address the status of biogeochemistry
and conservation biology within the framework of current environmental
policy and law.

B03 Closing the N2O budget through isotopic discrimination
Nitrous oxide (N2O) is a potent greenhouse gas and catalytic destroyer
of stratospheric ozone with an atmospheric residence time of about 150
years. The concentration of N2O has been steadily increasing in the atmosphere
over the past several years, but the budget is still incomplete. Unarguably,
the primary source of N2O to the atmosphere is from biological activity
in oceans and soils. Increased fertilizer usage has especially stimulated
the rates of microbial nitrification and denitrification, the main activities
which lead to N2O production. Over the past ten years, a powerful approach
has been employed to constrain the possible biological sources of N2O from
various environments by examining the distribution of N and O isotopes
within emitted N2O molecules. Combined with the preferential destruction
of specific N2O isotopomers in the stratosphere, we are now closer than
ever to closing the N2O budget in both its sources and sinks. This session
will highlight recent advances in quantifying the sources and sinks of
N2O using isotopic discrimination techniques by providing biochemical hypotheses
for how N2O isotopic discrimination occurs, describing spectroscopic techniques
for measuring N2O isotopomers, and presenting data that further quantifies
the N2O budget in natural systems.

B04 Species Populations and Relationships to Climate
and Water Quality
Biological indicators increasingly are being used to evaluate human
impacts on the environment. Declines in populations of many species have
prompted efforts to assess species abundance and to consider causes of
declines. For example, a worldwide decline in amphibian populations was
initially recognized in the late 1980's and has since been confirmed by
the scientific community. Many of the potential stresses to biota are related
to climate and water quality. This session seeks papers that link population
dynamics of biota to climate and the water quality of their environments.
Papers that address interdisciplinary studies in the following areas are
especially welcomed: long-term studies of population dynamics, malformations,
habitat loss or fragmentation, pathogens, introduced species, contaminants,
episodic events.

B05 Use of Remote Sensing as Policy Relevant Information
As public awareness grows that weather phenomena, climate change, water
resources and land use are inescapeably linked to human activities, health,
and prosperity through various degrees of cause and effect, policy makers
are forced to make decisions that often lack historical precedent. At the
same time, advances in remote sensing and the products derived from satellite
observations, including data assimilating model results, are revolutionizing
our understanding of the Earth System and increasing its predictability.
Therefore, it is imperative that the gap be bridged between lawmakers and
scientists so that policy reflects the most current state of knowledge
and embraces developing information systems. This session will encompass
remote sensing based research and applications that have influenced, do
influence, or should influence policy decisions, address the scientific
needs of policy makers, and describe both successes and deficiencies in
the link between Earth science and policy.

B06 Contributions of Biogeosciences to the Millennium
Ecosystem Assessment
The Millennium Ecosystem Assessment is an international effort to assess
the state of the world's ecosystems and their abilities to provide goods
and services important for human development. The assessment will involve
the contributions of hundreds of scientists over the next several years
and will provide information to policy makers on the current and future
condition of ecosystems (see http://www.ma-secretariat.org/). This session
will explore the contributions from the biogeosciences that make such an
assessment possible, including observation and modeling studies on a range
of ecosystems at regional and global scales.

interaction at various spatial and temporal scales. Field experiments,
remote sensing analyses, and modeling studies are all welcome. Energy,
water, and trace gas exchanges between the land and atmosphere will be
considered as well as the impact of these exchanges on climate.

B08 Ecohydrology of Arid and Semi-arid Ecosystems
In water-limited ecosystems hydrologic processes have a most significant
impact on plant physiology, nutrient cycles, fluxes of CO_2 and water vapor,
biomass production, plant growth and (plant) population dynamics. This
session solicits papers on the analysis of terrestrial ecosystems in water-limited
environments at different spatial and temporal scales. Both hydrological
and ecological studies on the role of the water cycle in soil-vegetation
systems will be important contributions to the discussion. The aim of this
session is to enhance, through the results of field studies and modeling
efforts, the understanding of the hydrologic and ecologic mechanisms controlling
ecosystems dynamics in arid and semiarid climates.

B09 Intercomparison of primary production models
and field observations
The continuing challenge of understanding the carbon cycle has led
to new era in which extensive field measurements of primary production
and related components of the carbon cycle are becoming available. Most
models that are capable of global application are limited in spatial resolution
by the availability of forcing data. This session will solicit presentations
on new data compilations, including recent syntheses from the literature
as well as new field observations. Presentations on the issues involved
in comparing model results that are at a coarser spatial resolution than
the field data will be encouraged. The main emphasis will be on comparisons
of these new data with the results of current models. The session as a
whole is designed to review progress and identify new opportunities for
modeling of primary production and its contribution to the need for monitoring
the global carbon cycle.

B10 Bridging the gap between ecosystem and atmospheric
studies of ecosystem-atmosphere CO2 fluxes
Process-level studies, including eddy-covariance flux towers, yield
a mechanistic understanding of the dynamics of ecosystem-atmosphere CO2
exchange, though on a small scale relative to biomes, continents or the
globe. The atmosphere integrates ecosystem-atmosphere CO2 exchange over
very large scales. Thus, the rate of change and spatial distribution of
atmospheric CO2 mixing ratios provide the ability to infer ecosystem-atmosphere
exchange of CO2 at global and zonal scales. The gap in spatial scales between
these approaches is very large. This gap limits our ability to connect
the process-level understanding derived from direct flux observations to
the observed global atmospheric CO2 budget. We invite presentations of
studies that attempt to bridge this gap in spatial scales. Possible topics
include upscaling tower fluxes using ecosystem models and remote sensing,
regional experiments using boundary layer budgets or airborne eddy-covariance
measurements, or syntheses of multiple flux towers across regional to global
scales.

B11 The Effects of Urban/Suburban Development on
Nutrient Cycling Processes and Water Quality
Human development in urban and suburban settings affects nutrient cycling
and water quality through additions of septic waste, treated sewage, pesticides,
and fertilizer to the landscape. Alteration of pre-existing runoff patterns
by paved and other impermeable surfaces results in rapid delivery of these
pollutants to waterways accompanied by enhanced sediment loads, resulting
in impacts on the biological community. Additionally, soil and groundwater
environments are altered by the movement of these same pollutants through
the subsurface. Because some of these pollutants are also nutrients, changes
in the types and rates of biotic and abiotic nutrient cycling processes
such as mineralization, adsorption/desorption, and reduction may also result.
Management of storm water runoff through creation of detention basins and
wetlands may partially mitigate these adverse impacts. Contributions for
this session are sought from investigators who have studied the effects
of urban and suburban development on water quality, and the resulting impacts
on nutrient cycling processes in aquatic and terrestrial biological communities.
Presentations focusing on the effects of mitigation strategies are also
welcomed.

B12 Lake Vostok: An ancient system?
The goal of this proposed biogeoscience session is to bring together
the community of scientists interested in the biota of deep subglacial
lakes with the physical scientists interested in the glacial and tectonic
boundary conditions. Lake Vostok is a deep subglacial lake capped by 4
km of ice resting in the center of East Antarctica. Recent identification
of viable microbes in frozen samples of the lake water raises the possibility
of a viable ecosystem within the lake, isolated from direct exchange with
the atmosphere for millions of years. The overlying ice sheet delivers
a flux of particles and microbes into the lake. The location of the lake
along a major geologic boundary indicates the subglacial geology controls
the location and form of the lake. This unique and ancient system represents
an unusual convergence of glaciologic, biologic and tectonic processes.

B13 The stimulation of plant production by rising
atmospheric CO2: did it trigger settled life and food production at the
end of the last glacial?
This session will explore the roles of the climate change and the rapid
increase in atmospheric CO2 concentration from about 190ppm during the
last glacial maximum to about 250ppm at the appearance of settled life
and food production. What was the climate during and following the LGM
at the loci of the origins of food production? Did low production of food
plants in require nomadic life and if so was it increased production of
the early domesticates that led to a shift to settled life? What were the
relative roles of climate and CO2 in stimulation of plant production? What
factors would have favored plant survival at low CO2 and the climate of
the LGM and were plants different at that time than modern representatives
of the founder species? These questions will be addressed by anthropologists,
plant physiologists, ecologists, and climatologists.

G02 GPS Navigation as a Tool for Earth Science
Precise positioning of moving GPS receivers is an enabling technology
for studing the Earth by remote sensing. It is a practical and affordable
way to get precise geographic registration for many kinds of data, and
speed and acceleration corrections, e.g. for air and sea gravimetry. It
is used in mapping topography, bathymetry, sea-surface, and ice thickness,
from ships, airplanes, and satellites, with various kinds of sonar, radar,
and lidar. New developments include the combination of GPS and acoustic
underwater positioning to monitor sea-floor tectonics, the observing in
real time of earthquake ground motion and volcano inflation, and the use
of buoys at sea to make tidal measurements, calibrate satellite altimeters,
or detect tsunamis; all this happens at a time when the increasing use
of robotic vehicles is opening the way to cheaper and faster surveys of
larger areas. Authors are encouraged to send abstracts on any of these
or similar topics; presentations are sought on both actual applications,
and on the relevant GPS techniques.

G03 Airborne and Spaceborne Laser Altimetry Observations:
Scientific Applications, Processing Techniques, and Synergy with other
Remote Sensing Observations
Laser altimetry from airborne and spaceborne platforms is rapidly establishing
itself as an invaluable technique for many purposes, including mapping,
surface characterization and 3D reconstruction. Products include detailed
topography and land cover data sets, which address fundamental issues ranging
from sub-canopy hydrography, to biomass estimates, to urban planning. Successful
spaceborne applications to date include the Shuttle Laser Altimeter (SLA),
the NEAR Laser Rangefinder (NLR), and the Mars Orbiter Laser Altimeter
(MOLA). Planned launches include multiyear missions such as the Vegetation
Canopy Lidar (VCL) and Ice, Cloud and land Elevation Satellite (ICESat),
which will yield global datasets on planetary topography, ice sheet mass
balance, ocean topography and landcover (vegetation). This session aims
to bring together an interdisciplinary group of scientists, engineers,
and end users working in the field of laser remote sensing. Topics of interest
include geolocation processing, system calibration and performance assessments,

GP01 Analysis of the Oersted, CHAMP, and SAC-C
magnetic field constellation
Previous missions to map the earth's magnetic field from space have
been isolated missions which had difficulty distinguishing between temporal
and spatial variability of the field. With the launch of Ørsted
(1999), CHAMP and Ørsted-2/SAC-C (2000), we now have three satellites
in near-Earth orbit measuring the scalar and vector magnetic fields at
the nT accuracy level. In order to improve the utilization of these unique
data sets, representatives of these projects have agreed to release to
the community a sample of data from all three satellites spanning a variety
of viewing geometries, local times, and magnetic disturbance levels. Associated
with this data sample will be descriptive models and indices. We solicit
presentations which describe the utility, analysis, and interpretation
of this coordinated data set, and other data sets. We welcome presentations
on external current systems, induction and crustal fields, and the main
field. We hope to have this data sample available prior to January 1, 2002,
so that everyone who wishes to participate in this session will have adequate
time to analyse this data, and other data sets. The session will be largely
online, with a single oral talk at AGU devoted to describing some of the
exciting results. We expect that the convenors will organize several question
and answer sessions online, pose questions for the participants, and summarize
the results. The focus will be on facilitating interactions between the
large but widely spread community (more than 50 international groups) which
is actively working on these data sets. An article advertising this session
will appear in an upcoming EOS and a summary article will appear, also
in EOS, describing the results of this interactive session. While the projects
and the convenors will select some of the data samples, we would like your
input NOW as to the data samples you would like to see from the projects.
Please email your requests to any of the convenors as soon as possible,
but no later than January 1, 2002. We look forward to hearing from you
and to a successful interactive session.

GS01 Application of trace metals to paleoenvironmental
change: Limitations and Challenges
Trace metal ratios (e.g., Sr, Mg, Cd, Zn) in biogenic calcite are important
tracers for paleoenvironmental change. For example, foraminiferal Mg/Ca
ratios have become a popular proxy for oceanic paleotemperatures. But each
tracer has its own limitations. A firm grasp of the challenges involved
in the application of trace metal ratios is critical for meaningful environmental
reconstructions. We welcome presentations that will address issues such
as, but not limited to, calibration of data sets to modern oceanic environments,
seawater geochemistry, biochemistry of trace metal uptake, or post depositional
alteration.

H01 Designing and Optimizing Long-Term Groundwater
Monitoring Programs
Long-term monitoring (LTM) is a key component of environmental management,
including monitoring natural attenuation and other remedial activities
and verifying the long-term integrity of remediated sites and containment
systems. Current practice often involves inadequate and/or redundant monitoring,
excessive sampling, and expensive analysis. This session promotes efficient
monitoring program design, consistent with satisfying appropriate site-specific
objectives. Topics include LTM sampling/measurement methods, selecting
monitoring alternatives, and LTM program optimization. Insights based on
research at natural attenuation field sites are welcome, as are perspectives
on future changes anticipated in monitoring paradigms and on issues involved
at CERCLA, RCRA, and federal sites.

H03 Characterization and Monitoring of Groundwater
Geochemistry and Bioavailability: Impact of Recent Advances in Analytical
Chemistry
Characterizing and monitoring groundwater geochemistry remains an important
challenge, creating a need for new tools in groundwater geochemistry. Recent
advances in analytical chemistry, such as provided by MC-ICP-MS , GC-C-IRMS
and ICP-OES provide new opportunities to understand groundwater processes.
Examples include: identification of recharge waters using element analysis;
determining the fate of platinum-group elements; and "fingerprinting" organic
pollutants. This session focuses on application of new analytical techniques
with emphasis on the potential to gain new insights into the characterization
of groundwater systems. Emphasis is placed on applications, statistical
methods for handling large data sets, and the interplay of new analytical
capabilities with established methods for groundwater characterization.

H06 Environmental Vadose Zone Hydrology (Poster
Only)
The vadose zone serves many important environmental roles and is an
important link as well as a buffer between the land surface-atmosphere
and groundwater. Poster presentations are invited on a broad range of topics
in environmental vadose zone hydrology including field investigations,
laboratory studies, and modeling analyses. Topics may include unsaturated
and multiphase flow and transport processes, plant-soil interaction, evaluation
and modeling of heterogeneous systems, assessment of prediction uncertainty,

H07 Uncertainty Assessments for Environmental Modeling
in the Unsaturated Zone
Multi-pathway models which simulate contaminant transport through the
environment to assess health affects (sometimes referred to as multimedia
environmental models) incorporate: simple to complex conceptual models
of flow and transport through the unsaturated zone to the water table;
hydrologic and transport parameter distributions; and human exposure scenario
assumptions and parameters. In order to build confidence in the calculations
from these models, uncertainty assessments and parameter sensitivity analyses
of the conceptual models, their input parameter distributions, outcomes
and scenarios need to be performed. This session will focus on the progress
being made in performing sensitivity and uncertainty analyses of risk-significant
unsaturated zone processes, parameter distributions, and scenarios incorporated
in the multimedia environmental models, and the cumulative uncertainty
in the estimation of performance measures. The session presentations will
discuss the use of these multimedia environmental models to evaluate potential
human health exposures using real site data and realistic assumptions.
Applications of multimedia models in codes such as 3MRA, RESRAD, DandD,
MEPAS, FRAMES and GoldSim to assess contaminant transport through the unsaturated
zone to the water table will be sought. The session will also include other
multi-pathway environmental model applications if contributed. The session
will help communicate recent developments and lessons learned from testing
uncertainty methods and parameter estimation techniques.

H08 Hydrology and Transport of Contaminants in
Riparian Zones
Riparian zones are lands adjacent to waterbodies like lakes, reservoirs,
rivers, streams, and wetlands. The functions of riparian zones are related
to their soil, vegetation, hydrologic characteristics and geomorphology.
Riparian zones usually are divided into three conceptual zones: zone 1
is adjacent to waterbodies; zone 2 is an intermediate zone upslope from
zone 1; and, zone 3 is the vegetated areas upslope from zone 2. Understanding
the hydrologic characteristics of these riparian zones is essential to
assessing their pollutant removal functions. This session presents research
on the hydrologic pathways and the transport and fate of contaminants through
riparian zones, especially occurring in the vadose zone and the hyporheic
zone. The vadose is subjected to unsaturated flow while the hyporheic zone
is a saturated zone below streams and banks where water exchanges occurs
between the surface and subsurface. Several areas of research are of interest
for this session, including theoretical, numerical, and laboratory/field
experiments investigating the transport and fate of contaminants (e.g.,
phosphorus, microbial pathogens, sediments, pesticides, hazardous-waste
landfills leachate) from the pore to regional scale, especially the Chesapeake
Bay and the New York City watershed.

H09 Bioclogging of Natural Porous Media
In a wide range of contexts, microorganisms have been shown to be particularly
effective at clogging natural porous media, i.e., obstructing their pore
space and reducing their permeability, sometimes by several orders of magnitude.
Bioclogging may be detrimental in some cases (e.g., in water wells or slow
sand filters), but beneficial and put to profitable use in other cases
(e.g., in subsurface biobarriers). In either context, a detailed understanding
of the mechanisms and environmental controls of bioclogging is desirable.
This session will review the state of the art in this emerging field. Topics
may include (i) laboratory experiments and microscopic techniques to understand
the process of bioclogging at the pore scale, (ii) intermediate scale experiments,
(iii) mathematical modeling of bioclogging at column- and field scales,
(iv) methods to obtain evidence of bioclogging in field situations, and
(v) discussions about criteria to assess the effectiveness of in-situ biocontainment
or biobarrier technologies.

H10 Links between Hydrology and Water Quality in
the Florida Everglades
Over the last 100+ years, the aerial extent of the Everglades has been
cut in half, the hydrologic flow has been altered by roads, levees, and
canals, and the water quality has been degraded by agricultural runoff
and other anthropogenic activities. Water quality, hydrology, and biogeochemistry
are intimately linked in this unique ecosystem. For example, surface water
flow is an important mechanism for phosphate transport; sulfate and oxygen
concentrations play key roles in mercury methylation; high water levels
and phosphate concentrations encourage cattail invasion, which in turn
affect water quality and hydrologic flow. We must have a good understanding
of these links if science-based restoration efforts are going to succeed.
Papers are encouraged on any aspect of the hydrology, water quality and
biogeochemistry of the Everglades, including field, laboratory, and modeling
studies.

H11 Water Quality of Natural Systems (Poster Only)
The quality of natural waters is determined by complex interactions
of hydrological, chemical, and biological processes. Poster presentations
are invited on all aspects of water quality, ranging from field and laboratory
studies to modeling approaches and theoretical work. Possible topics include
behavior of solutes or contaminants, interaction of hydrology and water
quality, geochemical reactions and processes, and novel techniques of analysis

H12 Science, Politics, and Watershed Management
The expansion of watershed management plans has involved many scientists
in the development of environmental policy and planning processes. The
watershed planning process involves the integration of scientific knowledge
with many different political actors and viewpoints. Effective watershed
management requires that this process be understood and implemented in
a manner that realizes both scientific competence and democratic procedures.
This session will examine both our current understanding of watershed processes
and the utilization of this knowledge in watershed management and environmental
policy development. In order to encourage discourse between natural scientists,
social scientists, and policy makers, this session seeks a broad array
of presentations related to watershed hydrology, ecology, management, and
policy. Examples of appropriate presentations include discussion of methods
that yield better understanding of watershed processes (and thereby contribute
to better decisions), discussion of regulation and/or management of development
in urbanizing watersheds, and analysis of the underlying societal trends
that drive both development and environmental regulations.

H13 Hydrologic and Water Quality Connections between
Mountains and Adjacent Lowlands
Virtually all of the world’s great river basins have important source
areas in mountains (e.g., the Andean source of the Amazon, Rocky Mountain
source of the Missouri, Alpine source of the Danube, and Himalayan source
of the Yangtze). The contribution of water, sediments, and dissolved solutes
from mountain sources far exceeds the proportional extent of mountain areas
in many of these basins. In addition to direct contributions from mountains
and their role in basin-wide mass balances, mountain-derived water and
materials may also have multiple indirect impacts on lowland systems. This
session invites contributions that explore the connections among meteorological,
weathering, and runoff phenomenon in mountain source areas and the resulting
hydrology and water quality of adjacent lowlands. It also encourages contributions
that consider the impact of changing land use and climate on mountain-lowland
linkages.

H14 The Role of Models and Data in the TMDL Process
A recently completed National Research Council study of the Clean Water
Act's Total Maximum Daily Load (TMDL) program assessed several issues related
to the scientific basis of the TMDL program, including the development
and use of information to identify sources of pollutant loadings and their
respective contributions to water quality impairment. The study recognizes
the importance of models in the development of TMDLs, and emphasizes the
importance of accounting for uncertainty and for using adaptive modeling
approaches. We invite papers that address several model-related questions
and recommendations made by the NRC Committee, including: (1) How can uncertainty
and error be explicitly considered in the estimation and application of
models used in the TMDL process? (2) What are the advantages and disadvantages
of relatively complex, mechanistic models versus conceptually simpler empirical
models for use in setting TMDLs? (3) How can models be used to estimate
impairment probability distribution for all waterbodies in a state? and
(4) How can monitoring data be utilized to revise and improve TMDL models?
Papers that consider the coupling of different types of models at different
scales are also encouraged. We encourage presenters to emphasize both the
strengths and weaknesses of the modeling approach they use and to discuss
the needs for further model development in light of the NRC recommendations.

H15 Predictability in Hydrometeorology
The global water cycle is maintained by diverse physical processes
in various geospheres. Models of different types and complexity can be
used to predict various aspects of the water cycle. Many of the natural
processes involved exhibit chaotic bahavior. Small changes in the state
of a system, due to either observational or model related uncertainties
lead to drastically different solutions after a finite time period, resulting
first in a partial, and eventually in a complete loss of predictability.
To be of use, forecasts in this environment need to be expressed probabilisticly,
instead of in the form of a single value. In this session studies related
to the predictability of hydrometeorological processes are solicited. This
includes theoretical studies aimed at assessing the predictability properties
of different subcomponents of the water cycle, as well as hydrometeorological
applications aimed at quantifying forecast uncertainty on various spatial
and temporal scales. In particular we invite contributions on different
methodologies developed for capturing case dependent forecast uncertainty
related to the use of imperfect models and limited observations. Papers
on the use of ensemble and related approaches in various hydrometeorological
forecast applications are especially welcome.

the distributed Model Intercomparison Project (DMIP) (http://hsp.nws.noaa.gov/oh/hrl/dmip/index.html)
to identify, to understand and to share science issues in distributed hydrologic
modeling through intercomparison of distributed models (among themselves
and with lumped models). Of particular interest to the host are those that
are particularly important at the space-time scales where operational hydrologic
models operate for purposes of flash flood, river flood and water resources
forecasting. The purpose of this session is (1) to provide a progress report,
particularly in the area of data preparedness and availability, and initial
results from limited model intercomparisons, and (2) to seek general contributions
from the community on all aspects of such a study, including data analysis
(including data quality), distributed and lumped modeling of soil moisture
accounting and routing, comparison of results between distributed and lumped
modeling, computational issues, objective assessment of model results,
assessment of marginal benefit of additional/finer-resolution data sources
and physical processes modeled, parameter estimation, data assimilation,
and development of forecast products from distributed model output. Contributions
from both participants and non-participants of DMIP are equally welcome.

H18 Coupled Watershed and Ecosystem Processes:
Methodologies, Models, Measurements and Management
The limited knowledge of 1) the coupling of hydrological mechanisms
to ecosystem structure and function and the effects of alteration activities,
and 2) sound methods to monitor important ecosystem characteristics and
the temporal and spatial changes resulting from system perturbations limit
the ability to manage land and water resources using an ecosystem driven
approach. This session focuses on multidisciplinary research that monitors
and models ecosystem processes at multiple spatial and temporal scales
within a watershed framework. This section seeks papers from field and
modeling-based research that examine the impact and interactions of soil,
vegetation and hydrological factors, from the hillslope to the landscape
scale, and their response to changing systems. Topics that include the
role of streamflow characteristics, soil water dynamics or flow paths on
watershed riparian processes, nutrient cycling, carbon uptake and habitat
modification are encouraged. Research that addresses the transition from
science to land and water resource management is also welcome.

H19 Impacts of Urban Land Use Change: Hydrologic,
Biogeochemical, and Policy Issues
As population in the U.S. and worldwide grows, pressures to urbanize
the landscape continue to mount. The east and west coasts of the U.S. are
highly urbanized with sprawl-type growth becoming a widely recognized phenomenon
associated with many urban centers. Development of the landscape leads
to a spectrum of negative hydrologic and biogeochemical consequences including
heightened flood flows, reduced baseflows, channel incision and erosion,
impaired groundwater recharge, changes in redox conditions, alteration
of aquatic and terrestrial biological communities, and increased nutrient
and pollutant loadings and concentrations. Scientists and policy-makers
are both focusing greater attention on these linked problems. Scientific
pursuits in this area range from tracking and quantification of urban growth,
to the creation of best management practices (BMPs) designed to mitigate
the impacts of urbanization, to the development of high resolution, physically-based
numerical models to estimate and predict nutrient concentrations in streams.
Policy-oriented efforts include the establishment of measures to curb urban
sprawl such as “Smart Growth” programs, and regulations to monitor and
limit nutrients and pollutants in streams. This session will attract a
blend of both science and policy perspectives to the problems associated
with urbanization. We invite papers that span scientific exploration of
urbanization impacts and the policy realm of controlled or directed development.
Appropriate scientific presentations would include the effects of urbanization
on runoff, recharge, erosion, nutrient cycling processes, water quality,
and species diversity in biological communities. Appropriate policy presentations
might discuss the effectiveness of low impact development, and government
or community efforts to create effective land development control programs.
Presentations that integrate science and policy such as the impact of land
use programs on runoff processes and water quality are particularly welcomed.

and Hydrometeorology
This session will explore the potential benefits and needs of the Global
Precipitation Mission (GPM) for hydrology and hydrometeorology. Contributions
are solicited that cover a broad range of topics related to GPM, with particular
emphasis on GPM's role for hydrology and hydrometeorology. This may include
issues of monitoring key components of the hydrologic cycle at the appropriate
scales in space and time, requirements for satellite sensor packages and
sampling, data fusion for multiple spaceborne sensors, assimilation of
GPM data into atmospheric and hydrologic models, and evaluation of the
satellite measurements from ground observations. This session is envisioned
as a platform to discuss the potential benefits for hydrology and hydrometeorology
resulting from GPM and the requirements and needs to accomplish them.

H22 Advances in Understanding the Global Water
Cycle
Growing recognition of the importance of variations in the cycling
of water through the Earth system has led to the development of a strengthened
Water Cycle program under the auspices of the US Global Change Research
Program (USGCRP). Water has important ramifications for the Earth system
in all its phases. As a gas it preferentially absorbs radiant energy emitted
by the Earth's surface thereby enhancing the greenhouse effect. As a solid
its high albedo reflects incoming solar radiation to space and its crystalline
structure allows it to store water both above and below ground particularly
during the winter months. Most critically, as a liquid it is an essential
source of fluid and nutrients for humans and animals, it provides essential
infrastructure support for society's economic activities and it serves
as a solvent and transport mechanism for many natural and manmade chemicals
and pathogens with both positive and negative consequences. Prediction
of the variability of the water cycle is a major issue because water excesses
in the form of floods constitute a major life-threatening natural hazard
while prolonged water deficits during droughts cause economic hardship
and social disruption. This session will be a mix of invited and submitted
papers dealing with the cycling of water through the Earth system with
a focus on pathways, fluxes and reservoirs. Papers are solicited that deal
with observation, analysis, simulation and prediction of the principal
components of the water cycle system and of the system as a whole. Papers
are also invited that address factors that introduce changes in the rate
of the cycling of water such as land use modification, changing atmospheric
composition and changes to water management practices. In addition to scientific
lectures, some USGCRP agency presentations will be included to provide
a context and overview for these activities.

H23 Remote Sensing, Hydrology and Field Experiments
This session hopes to bring together research in hydrological remote
sensing with emphasis on field experiments. In the past, numerous field
experiments have brought together data measured from different platforms,
including tower-, aircraft- and satellite-based measurements. These experiments
include FIFE, HAPEX, MONSOON-90, Mac-Hydro, SGP-97, SGP-99, to name a few.
Contributions are encouraged that examine the results from these varied
measurements in field experiments, the use of remote sensing in hydrology,
and the integration of remotely sensed measurements with measurements at
different scales.

modeling, and simulation to improve our understanding of land-atmosphere
interaction over natural terrain. Presentations concerning observations
in the atmospheric boundary layer (ABL) and at the land surface of mass,
heat and momentum transfer in the soil-plant-atmosphere continuum and the
development of models are welcomed. This includes discussion on the use
of remote sensing tools (e.g. lidar and radar) as well as the design of
new field experimental campaigns with fast response instrumentation, aircraft
and more conventional instruments to probe the ABL. In addition, talks
on the application and development of turbulence models, Large Eddy Simulation,
field campaign initiatives, and issues on coupling land and atmosphere
models including data assimilation are relevant in this session.

H25 Operational Monitoring of the Arctic Hydrological
System
The geography and dynamics of water across the Arctic region are important
elements of the larger Earth System given growing evidence of the vulnerabililty
of the Arctic climate and terrestrial biosphere to global change. The Arctic
freshwater cycle figures prominently in any analysis of these dynamical
systems, with important links among land, atmosphere, and ocean. Our capacity
to monitor this important environment is paradoxically deteriorating rapidly
relying on traditional sources of land-based data while at the same improving
dramatically with the emergence of numerical weather prediction models,
satellite-based remote sensing, spatial analysis and simulation modeling.
Several of these new tools have been used to provide a comprehensive picture
of change to the entire Arctic. This session seeks to highlight some of
these current capabilities and how these might be unified within a common
framework. Of particular relevance is a newly-proposed component of the
NSF Arctic Systems Science Program devoted to arctic water cycle synthesis
studies, Arctic-CHAMP (pan-Arctic Community-wide Hydrological Analysis
and Monitoring Program).

M03 Advances in Mineral Physics Using Synchrotron
Radiation
Synchrotron radiation sources provide extremely high-brilliance and
low-emittance x-ray beams. These sources, including the newly developed
third-generation synchrotron facilities, have opened up many new frontiers
in the study of fundamental physical and chemical properties of minerals
and other materials. New capabilities have been pioneered in the study
of crystalline and non-crystalline stuctures, elasticity, electronic and
phonon density of states, and rheology at conditions extending from near
the Earth's surface to those of the deep mantle and core. This session
will provide an interdisciplinary forum for the presentation of frontier
techniques and recent results from synchrotron-based studies of earth materials
with applications to the study of the large-scale structure of the Earth
and planets. We also encourage contributions using theoretical and other
experimental techniques that have relevance to the new synchrotron-based
methods.

M04 Viewing Seismic Observations Through the Lens
of Mineral Physics
Observations of the seismic velocity of the Earth represents one of
our most important constraints on the structure of the Earth's interior.
The interpretation of seismic velocity in terms of more physically relevant
properties, such as temperature, composition, mineralogy, and rheology,
relies on laboratory experimental data at high pressure and temperature.
Recent advances in seismology and mineral physics have produced large quantities
of high-quality data that are in need of interpretation. This session encourages
seismologists to present seismic observations that require mineral physics
data for interpretation, and mineral physicists to present experimental
data that can be used for interpreting seismic observations. Scientific
topics that would greatly benefit from this interaction include: o The
temperature dependence of transition-zone thickness. o The thermo-chemical
properties of ultra-low velocity zones at the CMB. o The composition, mineralogy,
temperature and rheology of the D" region. o The rheological basis for
deep earthquakes. o The cause and characteristics of seismic anisotropy.
Seismological observations and mineral physics data relevant to these and
other topics are strongly encouraged.

assessing the impact of human activities and climate change on coastlines.
This session seeks to examine the physical processes acting in salt marshes
and barrier islands. We welcome contributions that link field observations
and experiments with modeling and theoretical studies. Papers that investigate
the hydrodynamics, morphology, and sediment transport of coastal environments
are of interest. Particularly encouraged are studies that address the strong
link between morphology and vegetation. The goal of this session is to
present a general picture of salt marshes and barrier islands, with particular
emphasis on their morphological and ecological equilibrium.

P05 Mars from Two Perspectives: Global Surveyor
and Odyssey
For the first time since Viking in 1976, we have two spacecraft in
orbit around Mars. However, this time we can conduct synergistic observations
with the Thermal Emission Spectrometer (TES) on MGS and the Thermal Emission
Imaging System (THEMIS) on Odyssey. With these instruments we will be able

S01 Understanding the heterogeneity of the lower
mantle
Featuring extreme velocity decrements, decoupled P and S wave variability,
strong anisotropy and multiscale structure, seismic heterogeneity in the
lower mantle is clearly not exclusively thermal in origin. Layering, mixing,
melting, flow banding, and other effects are at work, but where, why and
with what effects? This session explores the evidence for these composition-
and state-induced variations in lower mantle elasticity and viscosity,
the mineral physics and geochemical interpretations of that evidence, and
the dynamic implications for planetary chemical and thermal evolution.

S02 Dynamics of the Oceanic Mantle
Plate tectonics and associated deformation at Earth's surface are the
manifestation of thermal convection in the mantle. The oceanic domain is
a logical focus for studies of mantle dynamic processes because fundamental
components of convection can have a simple tectonic manifestations beneath
the oceans, and the signatures of dynamic processes are far less likely
to be overprinted here than in continental settings. In recent years, models
have been developed to describe a number of important dynamic processes
beneath the oceans, including focused upwelling and swell formation at
hotspots, hotspot-ridge interaction, small-scale convection beneath the
plates, mantle flow and melt migration beneath spreading centers and propagating
rifts, and slab-induced flow in back-arc and fore-arc environments. A new
generation of seismic instrumentation and imaging, geodynamic theory and
modeling, and geochemical and petrological techniques are being used to
constrain and evaluate these models. This session will provide an interdisciplinary
forum for the presentation of recent results on all aspects of oceanic
mantle dynamics.

S03 Hotspots: Observations and theoretical models
The past few years have seen several new developments in studies of
both continental and oceanic hotspots. Seismic tomographic models of unprecedented
clarity have revealed the crustal and mantle structure beneath several
hotspots. An increasing number of geochemical studies have suggested the
presence of recycled slabs in the mantle beneath hotspots, but there are
few constraints on the amount or age of various recycled components. Recent
experimental studies on mantle rheology have led to dynamic models that
reconcile geochemical and geophysical data. New paleomagnetic data, however,
raise questions about the motion of hotspots and about the nature of associated
mantle upwelling. The objective of this special session is to bring together
researchers working on different hotspot systems to promote discussion
and comparison of observational constraints and theoretical models pertinent
to the dynamics and structure of the crust and mantle beneath hotspots.

SA01 New Results and Approaches to Observations
of the Atmospheric Limb
The Odin satellite, a combined astronomy/aeronomy mission supported
by Sweden, Canada, Finland and France, was launched from Svobodny in Russia
on February 20, 2001. The two instruments, a sub-mm/mm radiometer and a
combined optical spectrograph infrared imaging system (OSIRIS), observe
the terrestrial limb. The entire satellite is nodded in order to scan tangent
line of sight and permit the retrieval of atmospheric height profiles.
The early results from Odin have revealed the presence of atmospheric structures
and temporal variations that have not been previously observed, at the
same time these new observations also show the potential for misinterpretation
with traditional observing strategies. This special session will bring
together observers, theorists and modelers to consolidate what has been
learned so far and what needs to be done for a better understanding of
the results provided by this new approach to atmospheric observation. Emphasis
will be placed on the advantages afforded by combining the Odin approach
with other traditional observing approaches and the potential for new missions.
Contributed papers for oral talks and posters dealing with all aspects
of limb remote sensing are welcome. Conveners: *E.J. (Ted) Llewellyn, ISAS,

SA02 Preliminary Results from the Thermosphere,
Ionosphere, Mesosphere, Energetics, and Dynamics (TIMED) Mission
The Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics (TIMED)
satellite studies the temporal and spatial variations of the basic atmospheric
structure and energy balance between 60 and 180 kilometers. It will provide
at least 2 years of continuous, near-global observations of important geophysical
parameters from a 625 km circular orbit with a 74.1 degree inclination
using four remote sensing instruments. GUVI is a spatial scanning far ultraviolet
spectrograph that measures composition and temperature in the lower thermosphere,
as well as auroral energy inputs. SABER, an infrared radiometer, measures
pressure, temperature, and infrared cooling rates in the stratosphere,
mesosphere, and lower thermosphere. SEE, a spectrometer and a suite of
photometers, measures incoming solar irradiance. TIDI, a Fabry-Perot interferometer,
measures horizontal vector winds, temperature, and composition in the mesosphere
and lower thermosphere. The TIMED mission also includes numerous ground-based
collaborative observations. This special session will be dedicated to preliminary
scientific results and validation studies from both satellite and ground-based
investigators. In addition to invited speakers, contributed papers in either
oral talk or poster format are welcome.

SH01 Comparative Studies of Solar Activity During
the Rising and Declining Phases of Cycle 23
Advanced instrumentation has made possible a more detailed examination
of solar activity in Cycle 23 than ever before. Some aspects of these observations
hint at qualitative differences in the nature of solar eruptive phenomena
during the rising and declining phases of the Cycle. For example, from
November 1997 through 1998, there were numerous, moderate-sized solar energetic
particle events, many of which showed unusually strong fractionation effects
in elemental and isotopic composition. There was a relative dearth of significant
SEP events in 1999 and the first half of 2000. However, since July 2000,
SEP events have been both larger and more frequent, but with relatively
little indication of the strong fractionation effects observed during the
rising phase of solar activity in 1997-98. We invite comparative studies
of solar activity in the rising and declining phases of Cycle 23, to determine
whether or not these effects are real or perhaps merely a reflection of
limited SEP-event statistics. In addition to SEP studies, we particularly
solicit reports on solar wind, interplanetary conditions, CMEs, flares,
and radio observations, which may serve to clarify the extent of these
effects and their possible cause(s). We also welcome studies on similar
behavior in previous solar cycles and the potential significance of these
results for space-weather predictions.

SH02 Operational Space Weather Products and Models
A variety of space weather data and models are used as tools or direct
drivers for operational products that, in their totality, encompass all
venues (solar, interplanetary, magnetosphere, ionosphere, and neutral atmosphere)
of the space environment. These "operationally utilized" data, models,
and products often represent the "bottom line" of what many researchers,
analysts, and engineers have accomplished. It is important to understand
the difference between the tools and the true end-user (customer) products,
and to know which are truly operational. This special session seeks to
promote such distinction, along with information on current operational
product use, development, and validation efforts - ultimately pointing
out which space environmental variables should be scrutinized for potential
quantitative, qualitative, or timeliness improvement. Papers are invited
on current or imminent operational space weather products or tools, their
direct use, indications of their accuracy (validation), and ideas on how
to make them better.

SH03 Magnetic Topology and Complexity of CMEs
During enhanced levels of solar activity, CMEs and their interplanetary
counterparts make an important contribution to the transport of mass and
magnetic flux away from the Sun. Models have been used successfully to
understand a special, and conceptually simple class of CMEs - magnetic
clouds (flux ropes). However, the majority of CMEs observed in the heliosphere
are significantly more complex, showing a high degree of dynamic variability
and complex internal magnetic and plasma structure. The physical reasons
for this complexity are not well understood but may be related to: (1)
the initial structure of the source; (2) interactions of two or more ejecta
in the corona and/or heliosphere; (3) instabilities within the ejecta;
or (4) observational selection effects related to the spacecraft’s trajectory
through the event. This session will focus on both the experimental and
theoretical evidence for the causes of complexity of CMEs both in the corona
and solar wind. We particularly encourage contributions that discuss topological
aspects of CME-associated magnetic fields and their contribution to the
large-scale magnetic field in the corona and the heliosphere.

SH04 Energetic Electrons (70 eV - 1 MeV) and Related
Electromagnetic Emissions: Probing the Solar Corona and the Heliosphere
Fluxes and distributions of suprathermal and more energetic electrons
in the energy range from ~70 eV to ~1 MeV are highly variable in the solar
wind and are excellent tracers of magnetic field line topology and physical
processes occurring at distant sites. These electrons can be sampled directly
in situ and often can be detected remotely by the electromagnetic emissions
they generate. Sensitive new in situ and remote sensing measurements are
providing new information on the generation of these electrons at the Sun
and in the heliosphere , as well as on the magnetic topologies of the heliospheric
current sheet, CMEs, CME-driven and corotating shocks, and other heliospheric
structures. This special session will bring together theorists and experimentalists
to highlight and discuss recent developments in this expanding field of
research. Dennis K. Haggerty The Johns Hopkins University Applied Physics

The period of solar maximum is of special interest because it includes
the time when the Sun's magnetic field changes polarity. This session will
focus on the accompanying structural and dynamic changes in the heliosphere
during the recent maximum. Presentations will include observations from
spacecraft and ground-based instrumentation as well as results from models
intended to explain the effects of the changing sun and the interaction
of the solar wind and the interstellar medium. Spacecraft observations
during this period include those from IMP 8, Wind, and ACE; the Voyagers
in the distant heliosphere; Ulysses as it makes its fast latitude scan;
and solar observations from SOHO and Yohkoh.

SH06 The Heliosphere and its Surrounding Interstellar
Medium: Current State-of-Knowledge and Future Direction
The local interstellar medium (LISM) provides an accessible sample
of present day galactic matter and determines the boundary of our heliosphere.
The flow of neutral interstellar gas through the heliosphere and the interaction
with the surrounding medium at the boundaries provide ample opportunity
for not only in situ observations of particles and fields but also remote
sensing observations using photons and energetic neutral atoms. The simultaneous
availability of a variety of heliospheric data from spacecraft such as
ACE, EUVE, IMAGE, SOHO, Ulysses, Voyager, and Wind over the past five to
ten years has contributed to a rapidly growing understanding of the LISM
and its influence on the heliosphere. At the same time, vastly improved
heliospheric modeling provides a framework into which the observational
pieces fit and exciting new mission and instrument concepts promise to
answer some questions, but raise even more. The time has come to synthesize
results from myriad efforts designed to determine the physical parameters
and the material composition of the LISM, its interaction with the Sun
and solar wind through the formation of pickup ions and neutral solar wind,
and the size, shape and character of the heliosphere and its boundary regions.
We are inviting contributions on in situ and remote sensing observations
of interstellar neutral atoms, interstellar pickup ion populations, their
energetic products, neutral solar wind and other signs of LISM-heliosphere
interaction as well as related modeling and new measurement techniques
and missions.

SM02 Magnetic Field-Aligned Electric Fields: Causes
and Consequences
Electric fields directed along the background magnetic field play an
important role in the acceleration of charged particles in space plasmas.
The parallel electric fields which develop between the magnetosphere and
the ionosphere produce the aurora. In reconnection regions, such electric
fields produce plasma jets which pinpoint the diffusion region. Time-varying
electric fields due to solitary structures and waves also play important
roles in the physics of particle acceleration in these regions. Similar
processes are believed to produce observable astrophysical phenomena. Understanding
how these electric fields are created and the processes that result from
their existence is therefore important for understanding the physics of
the magnetosphere. Contributed papers dealing with theory and modeling;

SM03 Turbulence and Dynamics at the High-altitude
Cusp and Dayside Magnetopause Boundary Layer
The high-altitude cusp and dayside magnetopause boundary layer are
the major regions for transferring solar wind energy, mass, and momentum
into the Earth's magnetosphere. Large turbulent electromagnetic fields
and energetic charged particles with energies of 10-1000 keV are present
in these regions. This session addresses the turbulence and dynamics at
the high-altitude cusp and dayside magnetopause boundary layer. In-situ
observations from the CLUSTER II, IMAGE, INTERBALL, and ISTP missions and
theoretical studies for understanding of the solar wind drivers, acceleration
mechanisms, and plasma source and loss processes are most welcome for this
session.

SM04 Mysteries of Magnetotail Dynamics
An unique and scientifically powerful constellation of spacecraft for
the study of magnetospheric dynamics assembled recently when the Polar,
Cluster and Geotail orbits all penetrated into the region of the nightside
equatorial magnetosphere. These spacecraft observe magnetospheric dynamics
at the critical location where the dipolar magnetic field changes into
an extended tail-like field. Together with the global views of the IMAGE
spacecraft and in situ measurements at strategic positions throughout the
magnetosphere with the FAST, SAMPEX, GOES and Los Alamos geosynchronous
satellites, an unprecedented opportunity is offered to study the explosive
disruption and subsequent evolution of the magnetotail during substorms
and the unresolved reasons for the occurrence of the great magnetic storms.
These measurements are "jewels" of SEC research and will allow substantial
progress in resolving the mysteries of magnetotail dynamics. This special
session will bring together scientists from the above constellation of
spacecraft with interests in advancing our knowledge of magnetotail dynamics.
The participation of theorists and modelers in this session is equally
important. Emphasis will be placed upon contributions which provide advances
in a host of research areas such as plasma dynamics, connection to the
ionosphere, mechanisms for the elusive onset instability, and the evolution
of magnetotail phenomena during expansive and recovery phases of the substorms.
Contributed papers for oral presentations and posters for all aspects of
the nightside dynamical processes are welcome.

SM05 Research progress and model validation through
community access to state-of-the-art space science models
Traditionally, space research models have been primarily utilized by
individuals or small groups, which originally developed the model. This
led to a limitation of research benefits for the scientific community,
particularly for those not involved in modeling themselves. The necessity
to expand the usage of modern research models has been recognized in programs
of several agencies, most notably in the Geospace Environment Modeling
Program of the National Science Foundation. Another attempt to broaden
model access to non-modelers was provided by NASA's International Solar
Terrestrial Physics Program. The interagency National Space Weather Program
aims to develop end-to-end models of the space environment from the Sun
to the Earth for both research and operational applications. The growing
importance of Space Weather research activities enhances the need to expand
model use for the purpose of model validation through comparison with measurements.
The Community Coordinated Modeling Center (CCMC) is an activity, which
strives to accommodate these needs. CCMC provides, to the research community,
the benefit of usage of state-of-the-art space science models. Furthermore,
CCMC performs and supports model validation and evaluation against measurements
and metrics. This session will review scientific progress resulting from
community use of publicly accessible space research models. It will also
summarize advances in validation and metrics evaluations, and provide a
forum to discuss new candidate metrics against which models can be evaluated.

T03 A memorial session for Ronald W. Girdler: Rifts,
Ridges, Reversals, and Regional Studies
This session will be led by Tectonophysics, with GP and S co-convenors.
Ron Girdler had an active and productive career. Together with his many
students, he worked on several aspects of solid earth geophysics. From
his earlier work on rock magnetics and paleomagnetism through field work
in East Africa and the Red Sea to his later interest in the geologic signature
of impacts his studies encompassed a number of AGU sections. Mirroring
his career this special session of invited and contributed papers tries
to parallel Ron's broad interests with presentations which could broadly
be described as earth dynamics.

T04 The Chesapeake Bay Impact Structure: Results
from New Coreholes and Geophysical Surveys
The Chesapeake Bay impact structure is one of the earth's largest and
best preserved "wet-target" impact features. This 90-kilometer-wide (or
larger) complex crater lies buried within the Virginia Coastal Plain, U.S.A.,
where it was created 35 million years ago by an impact on the late Eocene
continental shelf. This structure has influenced the geologic evolution
of the Chesapeake Bay area to the present day and has produced anomalous
patterns of ground-water flow and salt-water distribution that place major
limitations on the use of the region's ground-water resources. This session
explores our rapidly increasing knowledge of the Chesapeake Bay impact
structure through an examination of recent corehole and geophysical investigations
conducted by the U.S. Geological Survey and affiliated agencies. These
studies provide important petrologic, geochemical, structural, stratigraphic,
and hydrologic data needed for inferring impact processes and for numerically
modeling these processes and the regional groundwater flow system.

T05 Active Deformation and Natural Hazards in the
Caribbean Region
The Caribbean region offers excellent examples of active tectonic processes
such as subduction, strike-slip faulting, and collision. As a consequence,
it is also severely exposed to natural hazard such as earthquakes, volcanoes,
or tsunamis. In the past few years, significant advances have been made
in imaging and understanding the plate kinematic framework and active deformations
along the boundaries of the Caribbean plate, thanks to a number of geophysical
and geological studies. In parallel, local governments and agencies are
becoming increasingly aware of the issue of natural risks in their countries.
This sessions aims at bringing together presentations of the most recent
results on active deformation processes in the Caribbean region, with a
particular emphasis on merging observational results (GPS geodesy, seismology,
paleoseismology, marine surveys, etc.) and models. Presentations discussing
implications on natural hazards and risks are particularly welcome.

V01 Element Partitioning and Diffusion in the Earth's
Interior
This session will discuss recent progress in the field of element partitioning
and diffusion at high pressures and temperatures. Geochemical models of
large-scale differentiation processes such as core formation, mineral fractionation
in a deep magma ocean, and partial melting beneath hot spots, mid-ocean
ridges and subduction zones require accurate studies of major and trace
element partitioning and diffusion at conditions relevant to the Earth's
deep interior. A combination of novel experimental and analytical techniques
has led to a large increase in the number and quality of these studies.
New data on the systematics of mineral-melt trace element partitioning,
metal-silicate melt partitioning, and major and trace element diffusion
in both solid and liquid phases will provide quantitative tests of geochemical
and geodynamical models for Earth differentiation.

V02 Education on Volcanology at the Graduate and
Undergraduate Levels
Volcanology is an interdisciplinary science and is thus an excellent
topic for education at several levels. Introductory courses may use examples
from volcanology to illuminate basic concepts. Advanced undergradute classes
offer a chance to integrate knowledge. Further, natural hazards are of
broad interest to the environmental studies community, and at the undergraduate
level, volcanology provides a good bridge to the environmental/social sciences
community. Graduate courses may be quite specialized, and are used to prepare
students for professional careers in research. In this session we intend
to explore the range and depth of courses offered in volcanology at many
universities, and to understand and improve the role volcanology plays
in general science education.

V03 Minerals, Solutions and Microbial Life
Microbes play an important role in the geochemistry of the planet.
This session will bring together theoretical, experimental and observational
studies on a variety of biochemical and geochemical systems that cover
low to extreme conditions of temperature, pressure, pH, salinity, desiccation,
and radiation. Papers addressing the interaction of biological systems
with geological processes on earth and outer planetary bodies are welcomed
as are papers on the origin/evolution of life and on the diversity/viability
of life in various geochemical environments. The development and application
of new experimental and analytical techniques added with natural observations
has provided new insights into the interaction of microbes with minerals
and aqueous solutions. Such biogeochemical studies have begun to provide
valuable insight into various biochemical processes as well as understanding
of the origins and limits of life. Experiments on hydrothermal biochemical
systems have provided new information about the evolutionary formation
of metastable and non-quenchable phases as well as kinetics and pathways
information at extreme conditions.

V04 Hydrothermal Environments: Coupling Experimental,
Field and Analytical Techniques
Understanding the physico-chemical conditions of magmatic-hydrothermal
ore-forming environments requires detailed knowledge of the melt-crystal-fluid
equilibria that obtain in such systems. This knowledge comes from two areas
of active geological research: 1) the analysis of melt and fluid inclusions
in natural systems; and 2) controlled laboratory experiments in which the
thermodynamics of ore-forming processes are determined. Techniques such
as laser ablation inductively coupled mass spectrometry allow us to accurately
determine the chemical composition of melt/fluid inclusions in fossilized
hydrothermal systems. Classical hydrothermal experiments allow us to map
out the physical chemistry of the evolving melt-crystal-fluid system at
the conditions that would have existed during formation of the hydrothermal
system. It is imperative that scientists from both camps come together
to discuss their data and hypotheses for additional research. This session
is designed to bring together both the analyst and the experimentalist
to discuss our recent data and hypotheses for future research.

V05 Determining Diamond Provenance
Diamonds continue to offer fundamental insights into Earth processes
ranging from bolide impacts to mantle dynamics. The need to remove so-called
"conflict diamonds" from the market has provided an added urgency to discover
characteristic properties that reveal the history of diamond genesis and
emplacement. This session will focus on the most recent advances in diamond
analysis and characterization and their implications regarding diamond
formation and provenancing.

V06 Volatiles and Light Elements in Magmatic Systems
This special session aims to bring together recent and on-going studies
which highlight the role of volatiles (e.g. CO2, H2O, SO2 Cl) and light
elements (e.g. Li, Be, B, F) in various magmatic systems, i.e. MORB, OIB,
subduction systems, etcetera. Especially important is the unique or clearer
insight the study of these tracers bring to our understanding of specific
aspects of magmatic systems. Contributions detailing a wide variety of
studies are encouraged: e.g. magmatic assimilation of various seawater-derived
or influenced components, contrasting on- and off-axis ridge magmatic systems,
compositions of phenocryst melt-inclusions, volatile fluxes in subduction
systems, geochemical and geophysical aspects of mantle regions. Also encouraged
are contributions showcasing advances in relevant analytical techniques,
theoretical approaches or fundamental behavior of these geochemical tracers.

V07 Multidisciplinary Constraints on Volcanic Volatile
Budgets
Volcanoes can emit volatiles both passively and explosively, impacting
the atmosphere, hydrosphere and biosphere on scales from local to global.
Volatiles are also released by magma bodies covertly, sequestered by hydrothermal
systems which may slowly accumulate at depth whilst decomposing and weakening
the core of the volcanic edifice. The action of different degassing regimes
during inter-eruptive periods will control to some degree the size of the
volatile reservoir that may be tapped during a major eruption, be it explosive
or effusive. However, illuminating the degassing processes acting at individual
volcanoes requires long-term campaigns. This session aims to bring together
remote sensors, petrologists, volcanologists, geochemists and hopefully
geophysicists to discuss topical work on the supply, storage and emission
of volcanic gases. Remote sensing using established and recently launched
instruments (TOMS, MODIS, ASTER) capable of quantifying SO2, sulfate aerosol
and ash in volcanic clouds has built a valuable database of observations
covering the last 25 or so years. Petrological estimates of volatile emissions
augment this database by extending it back prior to remote sensing and
into prehistory. Volcano monitoring using COSPEC, FTIR and other techniques
characterizes the size, chemistry and short-term variability of passive
volcanic plumes. We solicit contributions on these topics but also on studies
that illuminate processes potentially responsible for discrepancies between
remotely sensed and petrological data (e.g., the excess sulfur problem).
These could include magmatic gas scrubbing, sulfur speciation and thermodynamics,
hydrothermal studies and geophysical imaging of volcano interiors. Papers
on new instruments or techniques for measuring volatile species emitted
by volcanoes are also encouraged.

ED01 The Earth and Space Science Education Revolution:
A Call to Action
Fueled by new technologies over the last 40 years, advances in earth
and space science are revolutionizing our understanding of Earth's systems
and processes. This growing understanding is increasingly needed to inform
political and economic decisions of local, national and global impact.
In summer of 2001, at a national conference in Snowmass, Colorado, a "call
to action" was issued to scientists, educators, business leaders and policy
makers to the join in a parallel "revolution" to reform earth and space
science education in grades K-12. The purpose of this education revolution
is to insure that all citizens have the opportunity to learn about Earth
as a system and to investigate how earth systems interactions affect our
lives. The resulting conference report, outlines a vision for earth and
space science education in the next decade and sets out specific goals
and recommendations to achieve this vision. Among the key recommendations
are: (1) the formation of state-based alliances to promote earth and space
science education, (2) enhancement of efforts to increase diversity throughout
the earth and space sciences, (3) an annual national assessment on the
status of earth and space science education reform efforts, (4) the need
to work collaboratively with other science and education organizations
(and math and geography) to promote education reform across the board,
and (5) the need for additional research on teaching and learning of earth
and space science concepts. As the "revolution" moves from the planning
phase to implementation we are seeking abstracts from scientists and educators
working on projects which support earth and space science education reform
at local, state, and national levels.

ED03 Innovative Strategies for Enhancing Space
Science and Geoscience Education at all Levels
This session will showcase innovative teaching and learning of space
science and geoscience at all educational levels: Pre K-12, undergraduate,
graduate, and continuing education. We are especially interested in contributions
from programs that have made creative use of space & plasma physics
and other space & earth system science disciplines as contexts for
teaching the fundamental concepts articulated in the national science education
standards. We are also very interested in programs that have used the inquiry-based
principles of successful K-12 science teaching to enhance undergraduate
and graduate teaching and curriculum development in these disciplines.
Our invited speakers will represent these two strategies.

ED04 Math and Science Partnerships: School-College
Collaborations on a New Scale
The Elementary Secondary Education Act (ESEA) passed by both the House
and Senate contains language to support Math and Science Partnerships.
Much of the legislative language was based on proposals from the Bush administration.
This legislation would provide significant new opportunities for support
to universities and colleges to engage in collaborative efforts to support
high quality K-12 education. These partnerships are envisioned as bringing
math and science curriculum based on current research to the classroom
in forms that apply effective practice based on research on learning, assessment,
and pedagogy. This session will offer some comments about the current status
of the math and science partnerships programs as implemented in federal
agencies, and it will explore existing partnerships that provide models
for future work. Contributed papers demonstrating effective interactions
among science departments, schools of education, universities, school districts,
and state educational programs are encouraged.

High School-Aged Geoscientists
Several science programs in the Washington, D.C. and Richmond, VA region
allow promising high school students to conduct research on topics related
to the Earth and space sciences. This invitation-only session will highlight

ED06 Much Ado About Criterion Two: Does Anyone
Care?
In the spring of 1997 the NSF announced changes in its review process
that included two criteria to be addressed by reviewers. These criteria
are: (1) What is the intellectual merit of the proposed activity? (2) What
are the broader impacts of the proposed activity? The changes became effective
in the fall of 1997. With four years of the new criteria in place, there
is debate on how much impact the second criterion has had on both the writing
of proposals and in the review and funding decision processes. The National
Science Foundation and the National Science Board recently indicated the
need for enforcement of both criteria. Speakers for this session will include
NSF leadership who can provide a history of the evolution of the review
criteria, including the impetus for the 1997 changes, the intent of the
changes, and the desired outcomes in science research and education resulting
from the changes. Candidate invitees include Dr. Rita Colwell and Dr. Warren
Washington who chaired the subcommittee that made the recommendations for
the change. Other speakers, such as, Dr. Margaret Leinen, Division Directors,
and Program Managers will discuss the challenges of the implementation
of the new criteria within the NSF Geosciences Directorate, and help to
clarify the types of proposal elements that can satisfy Criterion 2. Contributed
papers are encouraged from the geosciences community that address how research
and proposal writing as well as proposal reviewing have adapted to the
new criteria.

Education and Human Resources also presents jointly with the
following Special Sessions:
V02 Education on Volcanology at the Graduate and
Undergraduate Levels
GC01 Climate and Development from Seasons to Centuries:
How our Understanding of and Responses to Seasonal Climate Variability
can Build Insight into Human Adaptation to long term Climate Change
The need for considering the interdependencies between climate and
development policy has gained prominent attention both in the US and internationally.
Research on understanding the relationships between climate variability
and human systems, particularly in the agriculture and water sectors, clearly
shows these links. The session will highlight studies that have focussed
on real world experience using seasonal climate forecasts by individuals
and institutions in developing countries and examine the implications for
adaptive responses to long term climate change.

GC02 Atlantic Decadal Variability
This session will focus on the long-term (decadal and multidecadal)
variability in the Atlantic Basin as seen in oceanic and atmospheric variables,
in observations, paleoclimatic evidence, and models and its relation to
global climate variability. It will consider recent findings on the characteristics
of the variability, the mechanisms proposed to explain them, and their
predictability. Abstract addressing the effects of Atlantic decadal variability
on the climate of the surrounding continents, changes in storm frequencies,
and the effects on ecosystems and fisheries, are also invited. The session
will consist of representative talks (solicited and unsolicited) and posters.

GC03 Pacific Decadal Variability
A proposed session of invited talks and posters outlining the problems
of identifying decadal variability in the Pacific from observations and
from paleoclimatic evidence, relating it to atmospheric variability, considering
the models that demonstrate decadal variability, and considering the mechanisms
and predictability that have been suggested for the generation of such
variability, including the relationship of ENSO decadal variability with
Pacific decadal variability in general. The effects of Pacific variability
on the climate of the US, in particular on the hydrology of the west coast
of America, and the effects of fisheries in the Pacific, will be an important
part of the session.

GC04 Carbon Management Technologies: Feasibility,
Impacts, Risks, and Economics
Strategies to capture and sequester carbon-dioxide (CO2) promise to
sustain fossil energy use by avoiding climate change. Consequently, technologies
such as CO2 injection into geologic formations or the deep ocean, stimulation
of natural biological terrestrial and oceanic CO2 sinks, air extraction
of CO2, mineral carbonation, and novel methods to generate fossil energy
that facilitate CO2 recovery are being aggressively explored. They are
at various stages of development ranging from being operational on a small
scale, to field-experimentation, to laboratory prototypes, to conceptual
designs. This session will examine these technologies by focusing on their
feasibility, scalability, environmental impacts and risks, and implementation
costs and time-constants. Our objective is to guide informed public policy
to secure our energy future.

GC05 Comparing Arctic Models
The Arctic is an important component of the global climate system.
This fact is highlighted by global climate model simulations that consistently
show the Arctic to be one of the most sensitive regions to climate change.
Although essential to interpreting model simulation results and their implications
for climate variability, an identification of the differences among models
and model systematic errors in the arctic has yet to be achieved. For this
reason, a set of symbiotic model intercomparison projects are currently
addressing different aspects of the Arctic climate system, for example,
the Sea Ice Model Intercomparison Project (SIMIP), the Arctic Regional
Climate Model Intercomparison Project (ARCMIP), the Arctic Ocean Model
Intercomparison Project (AOMIP), etc. Collectively, all these intercomparison
projects reflect a significant research effort towards improving the representation
of the Arctic region in global climate models. The goal of this session
is to bring together arctic researchers involved inthe model intercomparisons
and model validation studies in order to exchange ideas and methods of
model improvement based on the intercomparion approach. It is our hope
that this session will serve as a catalyst for researchers from different
fields, fostering a synthesis of major aspects of arctic climate system
modeling.

GC06 Reconstruction and Understanding the Late
Maunder Minimum Climate Anomaly
The Late Maunder Minimum (LMM; 1675-1715) is an extraordinary interval
in the historical climate record, with significant societal implications
at least in Europe. It has been documented by historical sources as well
as various proxy data. Furthermore, modeling studies are making progress
in reproducing this period, thus allowing for an analysis of the dynamical
background, in particular with respect to solar output and volcanic aerosol
loading. We solicit papers dealing with empirical and/or model-based analyses
of the climate response during the Late Maunder Minimum period.

PA01 Transferring Results of Climate Change Research
to the Private Sector: What We Really Need to Know
Are results from current climate change research relevant and useful
to the private sector? Conventional wisdom assumes that knowledge of climate
trends, uncertainties inherent in climate forecasts and modelling, the
state of knowledge of the carbon and water cycles, land–use effects on
climate, and paleoclimate studies are of interest to private sector. This
session will examine whether that is the case, or whether private sector
interests including energy, agriculture, and transportation ignore or are
not aware of research that might be relevant to their businesses. Speakers
and panelists in this session will also explore whether research questions
can be framed in such a way so that future results both advance the science
and help private sector interests plan for the future. Speakers from industry
and the research community will compare and contrast the needs of industry
versus the climate change research agenda. A panel discussion following
formal presentations will give speakers and the audience the opportunity
to develop points made during the individual talks.

PA02 Reconsidering Climate Change Research for
Policy Makers
Scientific research that supports global change policy is focused on
understanding the causes and predicting the future of climate change. While
this limited research agenda has been useful to advance our predictive
capability for climate, it has not expanded our understanding of how climate
change interacts with a broad range of other threats to environmental protection
and human development. New scientific knowledge suggests that decisions
about how to live, where to build, and what to leave untouched can have
a greater impact on society and the environment than some of the forecast
consequences of climate change. For example, future vulnerability to drought,
flood, hurricanes, and disease will increase for a number of interrelated
reasons, only one of which is human-induced climate change. Similarly,
continued urbanization, intensified and expanding agriculture, migration
of people to coastal regions, and exploitation of available water resources
cause global changes that cannot be understood solely by climate-focused
science and policy. This new knowledge points to the benefits of a broader
research portfolio as the U.S. considers action on this issue. Speakers
in this session will illuminate why research aimed at understanding a more
expansive view of interrelated environmental protection and human development
issues will provide greater value to policy makers and society. A panel
discussion among congressional representatives, scientists, and other policy
makers will aim towards identifying priorities for in a more comprehensive
global change research program.

PA03 Natural Hazards, U.S. Energy Policy, and
Climate Change: Making National Decisions in a Global Environment
Policy makers in the White House and U.S. senate are grappling with
the twin problems of making the country more resilient to natural hazards
and implementing a coherent energy strategy. Scientific uncertainty regarding
the magnitude and extent of future climate change requires that energy
and natural hazards policies for the U.S. have a long-term, global aspect.
An improved scientific understanding of the magnitude and extent of nature's
extreme events should underpin an improved policy response towards natural
disasters. A successful energy policy also must take into account what
scientists know and what policy makers need to know regarding the consequences
of a changing energy supply today and in the future. For example, will
energy policies developed in the near future exacerbate extreme weather
and climate events? In the future, the U.S. energy infrastructure will
become increasingly interconnected and potentially more vulnerable to disruption
as a result of extreme natural events, like earthquakes, hurricanes, floods,
severe weather, and space weather. Senators John Edwards (D-NC) and Ted
Stevens (R-AK), co-chairs of the Congressional Natural Hazards Caucus,
will address what they are doing to make the nation more resilient to natural
hazards. Vice-President Dick Cheney will discuss the Bush Administration's
energy policy proposal. All three speakers will comment on how geophysical
sciences can and should inform their efforts to implement an energy policy
that does not leave the nation's energy infrastructure exposed to natural
hazards. This would be a 5:30-6:30 evening slot immediately following the
technical sessions.

PA04 Dam Removal in the U.S.: How Does Scientific
Research Influence Decision-Making? Or, is Dam Removal an Art, Science,
or Neither?
Decisions to remove existing dams from U.S. waterways should include
careful consideration of impacts to river hydrology and ecosystems. What
are the scientific questions that need to be asked before policy makers
can act responsibly? Are researchers investigating aspects of hydrology
and watershed ecology that produce knowledge useful and useable to decision-makers?
This session will illuminate 1) what scientific issues are integral to
dam removal, 2) how the current state of knowledge bears on the U.S. policies
regarding dam removal, and 3) what research is needed to enable the local,
state, and federal interests to make better-informed decisions. The session
will be structured so that technical talks will address questions 1-3,
and a panel discussion will elicit views from policy makers and representatives
of the environmental community as to the relevance of current research
and to what extent scientific research will bear upon their actions.
