Geomorphic Evidence for Martian Ground Ice and Climate Change


Introduction: Recent results from gamma-ray and neutron spectrometers on Mars Odyssey indicate the presence of a hydrogen-rich layer tens of centimeters thick in the uppermost meter in high latitudes (>60 ̊) on Mars [1]. This hydrogen-rich layer correlates to regions of ice stability [2]. Thus, the subsurface hydrogen is thought to be water ice constituting… (More)
