Abstract:

Mars harbors ice deposits in several forms. The most known and accessible are the polar caps which are composed mostly of water ice, which also reside in the mid-latitudes shallow subsurface. 

Geologic observations suggest these deposits waxed and waned in the past, along with deposition and loss of tropical glaciers following periodic variations in the orbital elements.

We use a global climate model to study the evolution, interactions, and controls of the long-term Martian water ice (also CO2 and dust cycles) deposits and their observable geologic features, such as polar cap layers and mid-latitude subsurface glacier depth.
