“The Evolution of Martian Ice Reservoirs in Response to Orbital Forcing”

Water ice has played a central role in shaping the climate and surface of Mars throughout its history. In this seminar, I will present recent work investigating the long-term evolution of Martian ice reservoirs and the links between orbital forcing, atmospheric processes, and geological observations. Using climate and ice-evolution models, I examine how variations in Mars’ obliquity drive the redistribution of water ice between the poles, mid-latitudes, and the tropics on the surface and in the subsurface, producing climate states that differ dramatically from the present-day. These results and observations together provide a framework for reconstructing Mars’s recent climate history and demonstrate how present-day ice deposits preserve a record of past planetary climate states.

Planetary Lunch Seminar:
Topics span the range of the EAPS planetary sciences research program and are intended to appeal to any graduate students, postdocs, research scientists, and faculty with a background in planetary science. Speakers include members of the MIT community and visitors.
