Invited speakers

William "Breck" Bowden

Dr. Breck Bowden is the Patrick Professor in Watershed Science and Planning in the Rubenstein School of Environment and Natural Resources at the University of Vermont, where he is also the Director of the Vermont Water Resources and Lake Studies Center. His research interests focus on the interactions among land use, land cover and water resources, and his current research includes studies on climate change impacts in the Arctic. Dr. Bowden is active in national and international programs that seek to integrate science in resource management decision making, including the Long-Term Ecological Research (LTER) program, the National Environmental Observatory Network (NEON), and the Study of Environmental Arctic Change (SEARCH). His research includes studies of stream hydrology and hydrogeochemistry in permafrost landscapes; e.g., Bowden et al. 2008. Sediment and nutrient delivery from thermokarst features in the foothills of the North Slope, Alaska: Potential impacts on headwater stream ecosystems Journal of Geophysical Research - Biogeosciences 113: G02026.

Guido Grosse

Dr. Guido Grosse is a research professor at the Geophysical Institute of the University of Alaska Fairbanks (UAF). He received his MSc in Geology from the Technical University and Mining Academy, Freiberg, Germany, and his PhD in Geology from the University of Potsdam in collaboration with the Alfred Wegener Institute for Polar and Marine Research, followed by an International Polar Year Postdoctoral Fellowship at UAF. His research focuses on the effects of climate change in high-latitude terrestrial environments. In his current research projects in Alaska and in the Lena Delta, Russia, he uses remote sensing, GIS and field observations to study the changes in permafrost regions and their impacts on geomorphology, hydrology, ecosystems and the carbon cycle. His published work includes the review article: Grosse et al. 2013. Thermokarst lakes, drainage, and drained basins. Treatise on Geomorphology 8: 325-353.

Jan Karlsson

Dr. Jan Karlsson is a professor in the Department of Ecology and Environmental Sciences at Umeå University, Sweden. His research is mostly on low-nutrient aquatic ecosystems with a special focus on climate impacts on carbon and energy flow in alpine and subarctic lakes. His research questions include what controls the production of biomass from the bottom of aquatic food webs (bacteria and algae), via intermediate consumers (benthic invertebrates and zooplankton) to top predators (fish), and the influence of dissolved organic matter on biological productivity; e.g., Karlsson et al. 2009. Light limitation of nutrient-poor lake ecosystems Nature 460: 506-509. Another aspect of his research focuses on what controls the production of greenhouse gases in aquatic ecosystems, including the effects of land use and climate; e.g., Karlsson et al. 2013. High emission of carbon dioxide and methane during ice thaw in high latitude lakes. Geophysical Research Letters 40: 1123-1127.
