Professor, Environmental Studies and Earth Sciences

Jordan Clark’s research is focused on understanding hydrological and geochemical interactions that occur near the earth’s surface and the effects of external anthropogenic and climatic forcing on these interactions. His graduate studies on the Hudson River and, more recently, his research on Aquifer Storage and Recovery in California and aspects of the study on natural marine hydrocarbon seepage are examples of an effort to work on fundamental aspects of regional environmental problems. The remainder of his research time is spent examining geochemical problems related to global cycles and climate change (both recent and glacial/interglacial). His research on the hydrochemistry of springs, paleo-proxy data stored in groundwater, and methane emissions from hydrocarbon seepage illustrate this effort. Although his work examines problems in different environments, it is united by a common set of questions: how do transport processes affect water chemistry and quality and what are the impacts of climate change and other anthropogenic forcing on water chemistry and flow.
