Regions of Arctic water are becoming ice-free in late summer and early fall. A new study is the first to consider potential impacts on the marine mammals that use this region and identify which populations will be the most vulnerable to ships.

Reductions in sea ice in the Arctic have a clear impact on animals such as polar bears that rely on frozen surfaces for feeding, mating and migrating. But sea ice loss is changing Arctic habitat and affecting other species in more indirect ways, new research finds. Beluga whales that spend summers feeding in the Arctic are diving deeper and longer to find food than in earlier years, when sea ice covered more of the ocean for longer periods, according to…
University of Washington polar scientists are holding the 12th annual Polar Science Weekend, Friday through Sunday, March 3-5, at Pacific Science Center in Seattle. This year’s lineup includes a simulation from NASA of its new ICESat-2 instrument. Visitors can get scanned by an instrument above their head that measures a person’s height using an infrared distance sensor. The real ICESat-2 satellite, scheduled for launch in 2018, will map the Earth’s ice surfaces to very high precision, from space. During the…
A new study led by the University of Washington finds the annual migration of some beluga whales in Alaska is altered by sea ice changes in the Arctic, while other belugas do not appear to be affected.

James Cook’s intricate 1778 records reveal global warming today in Arctic” Seattle Times, Nov. 16 Harry Stern, a polar scientist at the University of Washington’s Applied Physics Laboratory, has been studying the Arctic Ocean for decades, and sailed part of the Northwest Passage in 2009. Stern’s latest work uses the earliest explorers’ experiences to better understand a maritime environment that still contains many unknowns. A paper published in November in Polar Geography uses Captain James Cook’s…
A new University of Washington study finds a trend toward earlier Arctic sea ice melt in the spring and later ice growth in the fall across all 19 polar bear populations, which can negatively impact the feeding and breeding capabilities of the bears.
A University of Washington expert on sea ice is part of a new book and museum exhibit focused on an idea that has captured many imaginations: a Northwest Passage that would allow ship traffic between the Atlantic and Pacific oceans. The book, “Arctic Ambitions: Captain Cook and the Northwest Passage” was published in March by the University of Washington Press. The accompanying museum exhibit opens Saturday, Oct. 17 at the Washington State History Museum in Tacoma. Book contributor Harry Stern,…
