Reappraisal of the fossil methane budget and related emission from geologic sources.

, 2008
Converging evidence from new top-down and bottomup estimates of fossil ‘‘radiocarbon-free’’ methane emissions indicates that natural geologic sources account for a substantial component of the atmospheric methane budget.

Potential Technosignature from Anomalously Low Deuterium/Hydrogen in Planetary Water Depleted by Nuclear Fusion Technology

The Astrophysical Journal
Deuterium–deuterium (DD) fusion is viewed as an ideal energy source for humanity in the far future, given a vast seawater supply of D. Here, we consider long-lived, extraterrestrial, technological societies that develop DD fusion.

Geospatial Analysis and Seasonal Changes in Water-Equivalent Hydrogen in Eastern Equatorial Mars

, 2014
This dissertation describes the relationship between hydrogen abundance, as measured through epithermal neutron counts, and the topographic, geologic, and surficial features in the equatorial region of eastern Mars. In Chapter 1, I present an alternative
