Steven R. Emerson, Ph.D. (Columbia Univ.), Professor.
emerson@u.washington.edu. Cycling of metabolic gases and isotopes in the ocean surface waters, air-water CO2 transfer in aquatic systems, the effect of anoxic conditions on solubility of metals in seawater, organic carbon and calcium carbonate preservation in marine sediments, and sediment pore water chemistry. Participating faculty in the UW Global and Environmental Chemistry Program (GEC), and Senior Fellow of the Joint Institute for Study of the Atmosphere and Ocean (JISAO).
