APL-UW has produced a video with Harry Stern and his research of the Arctic ice edge that incorporated logs and maps of Captain James Cook’s polar expedition among other early explorers.

Popular Science reported on Harry Stern’s research paper which analyzed observations recorded by the earliest explorers of the Northwest Passage in correlation to the current trend in sea ice.

UW Today highlights the latest article, by PSC’s Harry Stern and Kristin Laidre, published in The Cryosphere. Other media sources reporting the study are The Seattle TimesScience DailyThe Washington PostMashable, and Nature.com

The Polar Science Center’s Harry Stern contributed the essay called Sea Ice in the Western Portal of the Northwest Passage from 1778 to the Twenty-First Century in this new book by the University of Washington Press.

A new article published in Conservation Biology and featured in Science by lead author Kristin Laidre is the first to provide a comprehensive look at the current status of all Arctic marine mammal species and offer conservation recommendations.

Eurasia Review reports on the results of the lengthy study of beluga whale migration led by PSC and published in the journal Global Change Biology. The news post includes previous comments by some of the authors, Donna Hauser and Kate Stafford.

The University of Washington news produced a video with the Polar Science Center highlighting a six-year study of Beluga whale populations. Donna HauserKristin Laidre, and Harry Stern participated from PSC.

The news source International Business Times, out of the UK, reports on findings recently published in Global Change Biology of a decades-long research study involving Beluga whales. Donna HauserKristin Laidre, Harry Stern and colleagues examined changes in autumn migration timing of Beluga whale populations since the 1990s.

The publication Conservation Biology announced its awards for 2016 and PSC’s Kristin Laidre is the lead author of the paper that earned the second highest altmetric score, Arctic Marine Mammal Population Status, Sea Ice Habitat Loss, and Conservation Recommendations for the 21st Century.
Laidre led the collaborative effort which involved PSC colleagues Harry Stern and Eric Regehr (at present), along with other researchers from Canada, Greenland, Norway, Russia and other US institutions. Congratulations to Kristin and the team!

The Seattle Times covered Harry Stern’s research study which tracked changes along the Arctic ice edge combining modern technology and historical records such as maps and logs from Captain James Cook’s 18th-century voyage.

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.

Recent research by Kristin Laidre and Harry Stern on the impacts of climate change on Arctic narwhals is published in Polar Biology.  See the article in Conservation Magazine.

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.

BioScience talks to PSC’s Kristin Laidre for their coverage of combining remote sensing with animal tracking. Laidre and a field team of researchers tagged polar bears with telemetry devices, such as GPS collars, to collect data. Read the article to learn how Kristin and PSC’s Harry Stern used the remote-sensing data to study polar bear and sea ice trends. 

Harry Stern served as a respondent at the International Policy Institute (IPI) Arctic Fellows Research Symposium which took place on Friday, December 9 at the Henry M. Jackson School of International Studies on campus. The theme of the symposium was Arctic Indigenous Economies in Inuit Nunangat (Canada) and the Circumpolar World.

Science Daily, the popular science news website, posts coverage of the recently published study of the annual migration of some beluga whales altered by sea ice changes in the Arctic. The study and findings were published in Global Change Biology, authored by Donna HauserKristin Laidre, Harry Stern and Kate Stafford, among others.

Are climate scientists able to talk about their research without politics today? The Seattle Times talks with PSC researchers Axel Schwieger, Mike Steele, and Harry Stern who try to inform the public of the science behind climate change.
