Miller, Richard - New Insights Into the Polar Depth Distribution of Hydrogen at the Lunar Poles

We report new results on the depth distribution of enhanced hydrogen abundances at the Moon's North and South polar regions. The spatial distributions of hydrogen burial depth at both lunar poles have been estimated using a recent reanalysis of the epithermal and fast neutron datasets from NASA's Lunar Prospector mission, proven likelihood-based statistical analysis techniques, and comprehensive Monte Carlo simulations. Polar burial distributions provide additional insight into the processes relevant for lunar volatile deposits including burial, migration/mobility, and potentially their origin. Additional work includes comparisons with insolation, topographical, and temperature spatial distributions.
