Distribution of Martian ground-ice table: Preliminary results about climatic variationsRampart craters seem to have been emplaced by flows around craters over the surface just after the impact event by melting of volatiles. Such rampart craters are considered to be good ground-ice indicators. A map shows a latitudinal distribution of Martian ground-ice with a deep ground-ice table at equatorial latitudes and subsurface ground-ice tables at mid and high latitudes. Some studies suggest the presence of large amounts of ground-ice on Mars, with near surface ground-ice in the northern plains and a permafrost at low latitudes containing a large amount of volatiles at depth. Spatial variations in the spin axis of the planet affect the latitudinal distribution of the Sun's isolation, and therefore the Martian ground-ice distribution.
