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 Hauser, Kristin Laidre, Harry Stern and colleagues examined changes in autumn migration timing of Beluga whale populations since the 1990s.
The primary objective of this research is to construct a comprehensive bias-corrected sea ice thickness record and use it to better quantify and understand the dramatic changes that have been observed in the Arctic ice pack. To do this all available Arctic sea ice thickness observations will be integrated, from satellite, aircraft, and subsurface measurements, and used to identify and correct systematic errors through comparisons with a common reference. With the resultant record four science questions will be answered:• What are the systematic differences between different measurement systems for sea ice thickness?• What are the spatial patterns in the trends…
This project aims to understand and quantify the effects of sea ice loss on polar bears in East and West Greenland (Baffin Bay). Longitudinal (cross-time) comparisons of movement behavior and habitat selection will be driven by an analysis of a multi-decadal satellite telemetry dataset on polar bear movements in Baffin Bay and East Greenland, beginning when sea ice concentration and break up date started to decline (1991-1997) and encompassing present day conditions (2007-2013).
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.
