Filling the need for a 20-year lag in substantial consideration of the midlatitude ionosphere, this volume focuses on work that takes advantage of GPS and UV imaging from satellites over the past decade, two methods that have profoundly transformed our understanding of this stratum of the atmosphere. Its interdisciplinary content brings together researchers in the solar wind, magnetosphere, ionosphere, thermosphere, polar and equatorial ionospheres, and space weather.

This volume addresses the rapid decline of Arctic sea ice, placing recent sea ice decline in the context of past observations, climate model simulations and projections, and simple models of the climate sensitivity of sea ice.

Landslides are a constant in shaping our landscape. Whether by large episodic, or smaller chronic, mass movements, our mountains, hills, valleys, rivers, and streams bear evidence of change from landslides. Combined with anthropogenic factors, especially the development and settlement of unstable terrain, landslides (as natural processes) have become natural disasters.

Earthquakes, from the smallest to the largest, release elastic strain energy. Where does this energy go? How much is radiated and how much is expended in other source processes, such as overcoming fault friction? Do large and small earthquakes differ with regard to rupture physics?

The focus of Surface Ocean–Lower Atmosphere Processes is biogeochemical interactions between the surface ocean and the lower atmosphere. This volume is an outgrowth of the Surface Ocean–Lower atmosphere Study (SOLAS) Summer School.

Amazonia and Global Change synthesizes results of the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) for scientists and students of Earth system science and global environmental change.

Indian Ocean Biogeochemical Processes and Ecological Variability provides a unique synthesis of current knowledge on Indian Ocean biogeochemistry and ecology, and an introduction of new concepts and topical paradigm challenges. It also reports on the development of more extensive/frequent observational capacity being deployed in the Indian Ocean.

Carbon Cycling in Northern Peatlands examines the role that northern peatlands play in regulating the atmospheric carbon budget. It summarizes current research in four interconnected areas: large-scale peatland dynamics and carbon cycling; plant and microbial dynamics and their effect on carbon fluxes to the atmosphere; methane accumulation in, and loss from, peatlands; and water and dissolved carbon fluxes through peatlands.

For carbon sequestration, the issues of monitoring, assessment and verification of carbon content and storage efficacy are perhaps the most uncertain yet most critical issues facing the broader context of climate change in relation to carbon sequestration.

The cryosphere is a uniquely sensitive and strikingly symbolic indicator of change, but it remains one of the most poorly sampled components of the climate system. Ice sheets and glaciers are at the heart of the cryosphere. They act as a vast and enduring reserve of ice that contrasts with the widespread but transient seasonal snow and sea ice cover.

A study of the "eruptive crisis" that took place at the Stromboli volcano from December 2002 to July 2003. It features an integrative approach to the monitoring of eruptive activity, including: lava flow output, explosive activity, flank instability, submarine and subaerial landslides, tsunami, paroxysmal explosive events, and mitigation strategies.

This multi-disciplinary monograph provides the first modern integrative summary of the most spectacular active tectonic systems in North America. Encompassing seismology, tectonics, geology, and geodesy, it includes papers that summarize the state of knowledge, including background material for those unfamiliar with the region; address global hypotheses using data from Alaska; and test important global hypotheses using data from this region.

Hydrothermal systems at oceanic spreading centers reflect the complex interactions among transport, cooling and crystallization of magma, fluid circulation in the crust, tectonic processes, water-rock interaction, and the utilization of hydrothermal fluids as a metabolic energy source by microbial and macro-biological ecosystems.

This monograph is the first to survey progress in realistic simulation in a strongly eddying regime made possible by recent increases in computational capability. Its contributors comprise the leading researchers in this important and constantly evolving field.
