Vegetation-Induced Arid Hillslope Terracing
ECOHYDROLOGY AND BIOGEOMORPHOLOGY: HOW BIOTIC AND ABIOTIC INTERACTIONS CAN SHAPE LANDSCAPES AND ECOSYSTEMS ACROSS SCALES III ORAL
earth and planetary surface processes | 13 december 2024
Ida Gaulke, David Dunkerley, Alisha Matheson, Lelo...
On shallow arid hillslopes vegetation can grow in a pattern of alternating bands of presence and absence which follow topographic contours. This patte...

Climate Expressed in Aeolian Landscapes
ROBERT SHARP LECTURE
earth and planetary surface processes | 12 december 2024
Andrew Gunn
An aim of geomorphology is to infer aspects of climate from landscapes. The myriad ways landscape evolution is sensitive to climate properties like te...

Direct Measurements of Dust Settling Velocity Under Low‐Density Atmospheres Using Time‐Resolved Particle Image Velocimetry
GEOPHYSICAL RESEARCH LETTERS
30 july 2024
Carlos Alvarez Zambrano, Andrew Gunn, Christy Swa...
Dust dynamics influence planetary atmospheres. However, the settling velocity of dust—and thus its residence time in the atmosphere—is ...
Impact of Atmospheric Density on Dust Settling and Implications for Dust Dynamics on Mars
PROCESSES IN THE PRESENT-DAY ATMOSPHERE OF MARS III ORAL
planetary sciences | 15 december 2023
Carlos Alvarez Zambrano, Andrew Gunn, Christy Swa...
Understanding dust dynamics in planetary atmospheres is critical for modeling weather phenomena and climate, designing solar panels to power landed sp...

Global Analysis of Dune Patterns on Titan
SURFACE PROCESSES ACROSS THE SOLAR SYSTEM I POSTER
earth and planetary surface processes | 13 december 2023
Colin Marvin, Wen Bo, Jani Radebaugh, Andrew Gunn,...
Fields of linear dunes dominate Titans equatorial region. Because dunes evolve in concert with the winds, the patterns they form are tied to the dune ...

Hydrodynamic and Sediment-Transport Controls on the Size of Eolian Dunes Across Planetary Surfaces
GRANULAR AND FLUID PHYSICS ON EARTH AND OTHER PLANETARY BODIES III ORAL
earth and planetary surface processes | 12 december 2023
Mathieu G. Lapotre, Philippe Claudin, Andrew Gunn,...
Despite vast variations in fluid and sediment properties, fields of windblown dunes have been identified well beyond Earth, including on Venus, Mars, ...

Global Surface Winds and Aeolian Sediment Pathways on Mars From the Morphology of Barchan Dunes
GEOPHYSICAL RESEARCH LETTERS
21 september 2023
Lior Rubanenko, Andrew Gunn, Sebastian Perez-Lopez...
In the absence of consistent meteorological data on Mars, the morphology of dunes can be employed to study its atmosphere. Specifically, barchan du...
Conditions for Climate Interpretation in Aeolian Stratigraphy
DECIPHERING THE STRATIGRAPHIC RECORD OF SURFACE PROCESSES: NEW INSIGHTS INTO ANCIENT LANDSCAPE DYNAMICS ON EARTH AND OTHER PLANETARY BODIES II ORAL
earth and planetary surface processes | 16 december 2022
Andrew Gunn, Ryan C. Ewing
For given boundary conditions of sediment supply and climate, sand dunes have predictable morphodynamics and hence internal stratigraphy. From ancient...
