Eddy Carmack is a Senior Research Scientist Emeritus for the Department of Fisheries and Oceans at the Institute of Ocean Sciences in Sidney, B.C. He first ventured into Canada’s Arctic in 1969. A particular interest is to seek signals and causes of climate variability in lakes and ocean systems as well as subsequent repercussions to the food web and to resident fish and marine mammals. He has participated in over 90 field investigations in high-latitude rivers, lakes and seas from the Antarctic to the Arctic and from the Yukon to Siberia. Building on his investigations, he has published over 200 peer-reviewed scientific articles, over two-thirds of which contain original data. He is a Fellow of the American Geophysical Union, the 2007 Massey medalist of the Royal Canadian Geographic Society, the 2010 Tully medalist for the Canadian Meteorological and Oceanographic Society and he served as Sydney Chapman Chair at the University of Alaska, Fairbanks, from 2006 to 2016. He was Chief Canadian Scientist for cooperative studies of the subarctic North Pacific with Russia, for the 1994 Canada/United States expedition to the North Pole, for recent international studies in the Northwest Passage and Canada Basin and the Canada’s Three Oceans project for the International Polar Year. In retirement, he pursues research in the Northwest Passage and in B.C. waters he ‘captains’ his 34’ troller conversion R/V Wicklow to demonstrate undeniable value of small boat oceanography.
