Harry Stern

Harry SternHarry 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.
