Research interests lie in the general field of aqueous geochemistry and center on: 1) the transport of water and dissolved material in groundwater, surface waters, and the coastal ocean; 2) how flow patterns affect water quality; 3) gas exchange across the air-water interface; 4) climate change during the last 30,000 yr. These questions are examined using experiments conducted by introducing chemical tracers into the water bodies, plus analysis of flow patterns, residence times, and mixing rates inferred from the distribution of natural and anthropogenic tracers.
