Research
Interests
I am currently involved in a project to determine the relative magnitudes of submarine ground water discharge from marine and terrestrial sources. Click here for more information.
- Physical and chemical hydrogeology of karst aquifers
Most of my work on karst aquifers focuses on the Floridan aquifer. I am currently involved on several projects on this topic. One deals with understanding how water that flows through conduits exchanges with water of the high-porosity matrix rocks. Click here for more information. A project to begin next year involves developing tools to measure and predict nitrate fluxes through a karst water shed. Click here for information. Another current project involves exchange of nitrate and other nutrients between surface and ground wate in karst. Click here for more information.
- Deep
marine cold seeps and their record in biogenic and authigenic minerals
My work on cold seeps has evolved into projects trying to determine how long water discharges from the seeps using carbon isotopic compositions of foraminifera living in the cold seeps. Click here for more information.
