Gary A. Stern
Professor
University of Manitoba

ArcticNet Member(Biography) Dr. Stern is a senior research scientist with the Department of Fisheries and Oceans (Freshwater Institute, Winnipeg) and is the Head of the Arctic Contaminants Section. He is also an adjunct professor with the Departments of Environment and Geography and Soil Science, University of Manitoba. Dr. Stern’s research involves the study of environmental pathways of contaminants including their delivery, transport, and elimination from Arctic marine and freshwater aquatic ecosystems. In particular, it is directed toward linking contaminant levels in Arctic marine food webs to oceanographic provinces, inputs from land and the atmosphere and ultimately, climate variation which has been shown to alter for example, hydrology, organic carbon, sea ice dynamics, primary productivity, foodweb structure and foraging of top trophic level feeders such as beluga and ringed seals. Most of the major contaminant groups are being studied and include organohalogen compounds (chlorinated pesticides, PCBs, brominated flame retardants and florinated organic compounds), mercury and other trace metals, hydrocarbons and radionuclides. Dr. Stern was a participant in the international SHEBA (Surface Heat Budget of the Arctic) and JOIS (Joint Ocean Ice Studies) programs and is a PI in the Canadian Arctic Shelf Exchange Study (CASES) and the CFI Icebreaker proposal. In addition to being the project leader for ArcticNet Theme 3 sub-project 3.4, Carbon and Contaminant Cycling in the Coastal Environment, Dr. Stern is also co-leader of the Theme 1 sub-project 1.3, Contaminant and Cycling in the Coastal Environment and is an NI in the Theme 2 sub-project 2.6, Warming the Tundra: Health and Environmental Implications (Tundra). Currently, Dr. Stern also leads 2 projects funded by the Northern Contaminants Program designed to help test the effectiveness of international controls on contaminants such as PCB, DDT and PBDEs and, in conjunction with projects such as CASES and ArcticNet, to understand the effects that climate variation may have on the contaminant levels and the health of fish and marine mammal stocks. In collaboration with colleagues from the Department of Fisheries and Oceans, other government departments and universities, Dr. Stern, either as lead or co-author, has contributed to approximately 100 publications in the open literature.
