The Distribution and Preservation of Ice Sheets on Mars
The distribution and nature of water ice on Mars has important implications for not only understanding the Martian climate system, but also for evaluating the in-situ resources available for future human exploration and the astrobiological potential of our solar system.
I will present the results of several multi-faceted studies to investigate the distribution, properties, and preservation of ice on Mars. I will show how the properties of mid-latitude ice can be constrained using remote sensing observations from imaging and radar systems onboard NASA’s Mars Reconnaissance Orbiter, and discuss the importance of these constraints for understanding the planet’s climate.
I will discuss how I combine these remote sensing datasets with theoretical models of ice stability to understand the evolution and continued preservation of subsurface ice sheets to the present day. Lastly, I will present how analog studies, including field work at terrestrial glaciers and experimental laboratory studies of ice metamorphism, can elucidate the ice-related processes occurring on Mars and elsewhere.
