This map shows the estimated lower limit of the water content of the upper meter of Martian soil. The estimates are derived from the hydrogen abundance measured by the neutron spectrometer component of the gamma ray spectrometer suite on NASA's Mars Odyssey spacecraft. | This map shows the estimated lower limit of the water content of the upper meter of Martian soil.

Summary 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.
