Martian Thermokarst: South Arcadia Planitia And The Southern Mid-Latitudes

This data supplements the results presented in Viola & McEwen (2018), Journal of Geophysical Research: Planets, doi:10.1002/2017JE005366. The GIS databases presented here describe the presence of thermokarstic features (expanded craters and scalloped depressions) and pedestal craters found in images from the High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter (MRO) within two study regions: southern Arcadia Planitia (25–40°N, 180–240°E) and the southern mid-latitude band (30–60°S). These features suggest the presence of near-surface excess ice on Mars.
