Biological Oceanography Division

photo The Division of Biological Oceanography offers a broadrange of exciting research opportunities in diverse marine habitats and ecosystems around the globe, from tropical to polar oceans and from the air-sea interface to the deep-ocean floor. Upper water-column programs include studies of primary productivity and bio-optics, color satellite imagery, plant pigments as tracers of biogeochemical processes, microbial food-web interactions, phytoplankton and zooplankton community structure, and the roles of biota in vertical transport andremineralization of particulate and dissolved organic matter. Mid-water column studies focus on the community ecology and dynamics ofmeso-pelagic shrimp, squid and small fishes unique to oceanic island systems. Benthic research programs involve coral reef ecology and evolution, effects of environmental disturbances on deep-sea community dynamics and recruitment, chemical cycling, burial, and bioturbation in the sediments, and the microbial ecology of tube-building animals and bioturbation in the sediments, and the microbial ecology of tube-building animals and hydrothermal vent systems. Both water-column and benthic investigators are actively involved in high-profile Global Change programs in the Pacific - including coastal margin, open ocean, and equatorial upwelling studies.

Divisional programs emphasize basic research, but many are relevant to applied problems and societal concerns such as the fate of "green-house" gases, ecological impacts of ozone depletion and deep-seamining, mechanisms of pollutant transport and cycling, and fisheries recruitment. The interdisciplinary nature of these and other problems fosters strong collaborative interactions between Division biologists and geochemists and physicists in the Department and at other institutions.
