Session Description:
Planetary missions over the past decade have revealed that while planetary bodies across the solar system differ greatly in surface conditions, their landscapes share striking similarities to those on Earth. Understanding the feedbacks between how geophysical flows and sediment transport processes affect landscape evolution is necessary for constraining the current and past climatic conditions on such planetary surfaces. We invite contributions from research exploring these interplays using remote sensing data from surface or orbital missions, numerical modeling, laboratory experiments, Earth analog studies, or some combination thereof. We expect that a joint session between Planetary Sciences Section and the Earth and Planetary Surface Processes Focus Group will foster collaborations between those working to understand how geophysical flows and sediment fluxes modify our own planet’s surface under changing climates and those who are working to understand how such surface processes behave in places with vastly different conditions and constraints from our own.
