Research emphases

Our research focuses on the dynamic carbon and water cycles.

 

We apply geochemical tracers and numerical modeling to:

1. trace sources of carbon and water on Earth,

2. document elemental transport across the air-water-soil interface; and

3. understand the effects of climate and land use change on elemental behavior in the environment.

Chemical weathering and the C cycle

Chemical weathering and the C cycle

We discern the controls on chemical weathering rates and the feedback between weathering and climate and geology, Participants: B. Hagedorn, I. Cartwright, R. Whittier, Support: U.S. Bureau of Land Management

Groundwater recharge

Groundwater recharge

We quantify groundwater availability in complex watersheds using radioactive (carbon-14, tritium) tracers and water balance models, Participants: B. Hagedorn, A. El-Kadi, A. Mair, S. Tillery, Support: KIGAM

Environmental forensics

Environmental forensics

We apply isotopes and molecular tracers to trace the sources of contaminants in water and soils, Participants: B. Hagedorn, H. Kerfoot, Support: Waste Management, inc.

Geospatial analysis

Geospatial analysis

Using geostatistics we we evaluate the spatio-temporal distribution of hydrologic parameters in complex settings, Participants: B. Hagedorn, A. mair, A. El-Kadi, S. Tillery, Support: KIGAM

Aquifer sustainability

Aquifer sustainability

We use numerical modeling to evaluate the response of groundwater systems to projected climate, land use, and pumping scenarios, Participants: B. Hagedorn, A. El-Kadi, S. Tillery, R. Whittier, A. Mair, Support: KIGAM
