AND RESEARCH AREAS
Teaching effort emphasizes plankton ecology. One major research thrust examines how Protist behavior and physiology influence the ecology of selected species. As a participant in the ECOHAB: Florida Project, we investigated how Karenia brevis uses cues related to its circadian rhythms, its internal physiological/biochemical state and its external environmental exposure to determine cell location in the water column and thus to transporting current regimes on the west Florida shelf. Other ECOHAB funding support associated laboratory work using mesocosms and field work using a programmable Lagrangian drifter termed the K. breve population mimic. A second major research thrust is to develop a capability to monitor phytoplankton nutrients in the world ocean using remotely sensed temperature and to apply this capability to an improved interpretation of phytoplankton biomass and production based on remotely sensed ocean color. This temperature-nutrient association also was applied other temperature data sets in the world ocean including the ARGO floats and a 20th century sea surface temperature data set (ERSST). The latter analysis characterized variability in the thermohaline circulation and the implications for ecosystem variability in the world ocean. Other research interests included the oceanography of the Galapagos archipelago with special emphasis on phytoplankton community structure and the source of atmospheric isoprene over the world ocean.
