Harry Stern studies Arctic sea ice and climate using satellite data. Current interests include the changing sea ice habitat of polar bears and narwhals, and the history of Arctic exploration. He participated in the Around the Americas expedition, sailing through the eastern half of the Northwest Passage in 2009. He served as an Associate Editor for the Journal of Geophysical Research–Oceans (2007-2010). He helped to launch the annual Polar Science Weekend at Seattle’s Pacific Science Center, and now runs the event. He has a B.S. in mathematics and M.S. in applied mathematics. He has been with the Polar Science Center since 1987 and with the University since 1980.
In The News
The UW Today reports on the open-access study recently published in the Journal of Applied Ecology by PSC’s Eric Regehr and a collaborative team, including Harry Stern. The team combined data collected on polar bear subpopulations with that of sea ice extent and identified ways to carry on subsistence harvesting with the least amount of negative impact already caused by habitat loss.read more »
The Alaska Dispatch News reports on the study published in Global Change Biology of beluga whale migration patterns influenced by changes of the annual Arctic freeze-up. PSC authors include Donna Hauser, Kristin Laidre, and Harry Stern. The article also makes a parallel comparison to a study of ice retreat, published in JGR Oceans, co-authored by PSC’s Rebecca Woodgate.read more »

In search of the Northwest Passage, Captain James Cook was the first to actually probe and chart the ice edge north of Bering Strait. Polar Geography has published Harry Stern’s research of Cook’s exploration of the Arctic and how other expeditions fared in comparison, resulting in a history of sea-ice observations from Cook’s time to the present.read more »
