Specific Research Interests: Our interests focus on the interactions of phytoplankton and zooplankton in the pelagic environment (coastal and open-ocean). We utilize radioisotope/spectroscopic techniques and organic analyses to understand rates of autotrophic production and heterotrophic consumption in the planktonic environment. In particular, we are interested in all aspects of photosynthetic pigments as they relate to the understanding of phytoplankton physiology/taxonomy. These techniques are being applied in the study of environmental problems including thermal stress, invasive species and long-term environmental change. Current Projects: (1) evaluation of ballast treatment in mitigating the aquatic non-indigenous species problem; (2) effects of thermal stress and entrainment from power plant cooling circulation; (3) long term analyses of planktonic processes in Elkhorn Slough CA; (4) reassessment of global phytoplankton productivity.
