Polar Science Weekend returns to Seattle’s Pacific Science Center for the eleventh straight year March 4-6, 2016.
Experience hands-on activities, live demonstrations and exhibits presented by UW glaciologists, biologists and climate experts along with other community members devoted to polar environments.
UW Today spreads the word that Polar Science Weekend has arrived. Event is March 4-6, Friday 10am – 2pm. Saturday & Sunday 10am – 6pm.
Entrance is included with Pacific Science Center admission. Polar Science Weekend is a partnership between Pacific Science Center and the UW’s Polar Science Center and Applied Physics Laboratory, with support from PEMCO Insurance Company, the College of the Environment’s Future of Ice Initiative and the UW’s Quaternary Research Center.
Kristin Laidre participated in a panel discussion held at AGU’s 2016 Fall Meeting in San Francisco. She presented population projections for polar bears across the Arctic during the discourse of how satellites observe habitat change and help scientists forecast how species will respond.

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.
Mashable, the online news source, covered a study, published in the journal Geophysical Research Letters, of a 20-mile-long rift in Pine Ice Glacier that eventually broke through the surface and cleaved off a 225-square-mile iceberg in July 2015. Mashable contacted PSC Glaciologist Ian Joughin to comment on the findings.
Nature has reported on the Global Land Ice Velocity Extraction project (GoLIVE), recently announced at the AGU Fall Meeting 2016. This NASA-funded project uses perpetual data from the Landsat 8 satellite to monitor glaciers and ice sheets. The news source asked PSC Glaciologist Ian Joughin for comment.

NOAA released its annual “Arctic Report Card” and Gizmodo presented research findings by Kristin Laidre, among others, to help readers interpret the “grade”.
Kristin Laidre led a research team that investigated the importance of glacial habitats using telemetry data from Narwhals which were captured and instrumented with satellite-linked time–depth–temperature recorders in Melville Bay, West Greenland, over numerous years. Read about the findings in Biology Letters.
