Geobiology of Biofilms in the Continental Subsurface

Description:

If life exists on Mars, it likely resides in a deep subsurface environment. The Martian rocky subsurface is a primary target for the search for extraterrestrial life because it offers a stable habitat for microbial life. On Earth, the continental subsurface is a key astrobiological analog for understanding what properties...

Carbon Cycling of Glaciated Landscapes on Modern and Geologic Timescales: Investigation with Strontium and Carbon Isotope Geochemistry

Description:

The studies presented in this dissertation combine radiogenic and stable strontium isotope ratios (87Sr/86Sr and 88/86Sr, respectively), radiogenic and stable carbon isotope ratios (Δ14C and 13C, respectively), and bulk ion geochemistry to trace the sources and cycling of C in three glaciated environments (New Zealand, Iceland, and Greenland). A primary...
