Georgina Gibson

University of Alaska Fairbanks

george@ims. uaf. edu | I grew up on the Isle of Wight, a small island off of the south coast of Britain. Being constantly surrounded by water fueled my desire to study the ocean. I am particularly interested in how changes in the physical ocean influence biological production. I received my joint honors BSc in Marine Biology and Oceanography from the University of Wales, Bangor and my PhD in Biological Oceanography from the University of Alaska Fairbanks.

I am presently a marine ecosystem modeler with the Arctic Region Supercomputing Center in Fairbanks, Alaska. My use computational approaches to explore marine ecosystem dynamics and improve our ability to rapidly detect changes in marine ecosystems, as well as to and predict future change in marine productivity, with the goal of developing tools to aid in sustainable fisheries management. I specialize in lower trophic level, NPZ food web models and am currently developing a coupled NPZ-ROMS model with a benthic sub-model for the southeast Bering Sea.

Rolf Gradinger

University of Alaska Fairbanks

rgradinger@ims. uaf. edu | Rolf Gradinger is an Associate Professor of Oceanography at the University of Alaska Fairbanks School of Fisheries and Ocean Sciences. During his Masters thesis work at the University of Kiel, Germany, he focused on phytoplankton species distribution patterns in the Greenland Sea (completed 1986). His PhD thesis (also Kiel University) focused on the functional role of heterotrophic nanoflagellates in the Arctic (completed 1999).

During his Post-doc period he started to work on Arctic and Antarctic sea ice communities –- a focus he has kept until today. Since 2001, he has worked at the University of Alaska Fairbanks and was involved in various Arctic research initiatives, including the Shelf-Basin Interaction Study or the Arctic Ocean Diversity project. Rolf's involvement in BEST is through joint work with Bodil Bluhm, Katrin Iken and University of Alaska graduate students on the role of sea ice algae for herbivorous plankton and benthos in the Bering Sea.

Jacqueline Grebmeier

University of Maryland

jgrebmei@cbl.umces.edu | Jacqueline Grebmeier is a Research Professor and a biological oceanographer at the Maryland Center for Environmental Science Chesapeake Biological Laboratory. She is the US delegate to the International Arctic Science Committee, a current member of the US Polar Research Board of the National Academies, and served formerly as a Commissioner of the US Arctic Research Commission following appointment by President Clinton. She has contributed to international and national science planning efforts including service on the steering committee for US efforts during International Polar Year.

Over the last 20 years she has participated in more than 35 oceanographic expeditions on both US and foreign vessels, many as Chief Scientist. She is the overall project lead scientist for the US Western Arctic Shelf-Basin Interactions project, one of the largest US funded global change studies now underway in the Arctic.

Her research includes studies of pelagic-benthic coupling in marine systems, benthic carbon cycling, benthic faunal population structure, and polar ecosystem health. She has published in many peer-reviewed scientific papers. Her role in many international research projects includes coordination of benthic biological and sediment tracer studies and analysis of ecosystem status and trends on Arctic continental shelves. A recent study in which she was lead author was published in Science and provides some of the first direct evidence for biological community responses to warming and oceanographic shifts in the Bering Sea ecosystem. Dr. Grebmeier has also served as editor of several books and journal special issues.
