Jacqueline Grebmeier

Dr. Grebmeier’s oceanographic research interests are related to pelagic-benthic coupling, benthic carbon cycling, and benthic faunal population structure in the marine environment. Over the last 30 years, her field research program in the Arctic has focused on such topics as understanding how water column processes influence biological productivity in Arctic waters and sediments, how materials are exchanged between the sea bed and overlying waters, and documenting longer-term trends in ecosystem health of Arctic continental shelves. Some of her research projects have included analyses of the importance of benthic organisms to higher levels of the Arctic food web, including walrus, gray whale, and diving sea ducks, and studies of radionuclide distributions in sediments and within the water column in the Arctic as a whole. In other work, she has studied the influence of oceanographic processes on benthic communities in Antarctica, chemical exchange at hydrothermal vents systems in the equatorial eastern Pacific Ocean, and the transport and fate of materials in melted snow in Arctic tundra in the Brooks Range foothills.
