DescriptionWater equivalent hydrogen abundance in the lower latitudes of Mars 01.jpg
English: This map displays the proportion of water ice present in the upper meter of the Martian surface within 60 degrees of the equator. The percentages are derived through stochiometric calculations based on epithermal neutron fluxes. These fluxes were detected by the Neutron Spectrometer aboard the 2001 Mars Odyssey spacecraft.
