Tamara Harms Assistant professor Institute of Arctic Biology and Department of Biology & Wildlife University of Alaska Fairbanks [email protected] I am an ecosystem ecologist studying cycles of carbon, nitrogen, and phosphorus in streams, riparian zones, and catchments. In the Arctic, I have worked to document potential links between permafrost thaw and export of dissolved carbon and nutrients, including sources of nitrate to arctic streams, and the role of hillslope flowpaths in propagating and transforming exports from terrestrial ecosystems to receiving streams. In addition to my field-based research, I am currently a fellow of the Fulbright Arctic Initiative, working with an inter-disciplinary group of scholars to produce policy-relevant research addressing potential consequences of increased freshwater delivery to the Arctic Ocean. I have three central interests in contributing to the steering committee of SEARCH. First, I would like to contribute to enhanced international collaboration regarding arctic research. There is an imperative to understand the arctic as a whole, and opportunities to link our local- and regional-scale studies to yield pan-Arctic synthesis. Second, I am interested in achieving more effective communication of research findings to the public and policy-makers. Recent executive-level attention to the Arctic by the US and Canada has a created a moment in which such outreach might be particularly effective. Finally, I am interested in identifying arctic issues requiring inter-disciplinary efforts, and promoting the creation and funding of teams to conduct research tackling these issues. Tamara K.
