Study will help biologists track wild polar bears’ response to climate change

PORTLAND, Ore. — Tasul, an Oregon Zoo polar bear, recently landed her first white-collar job: research assistant for the U.S. Geological Survey. Her assignment: wearing a high-tech collar to help solve a climate change mystery.

“Scientists and wildlife managers need to understand how polar bears are responding as sea ice retreats,” said Amy Cutting, Oregon Zoo curator. “But polar bears are notoriously difficult to study in the wild. Direct behavioral observations are nearly impossible.”

Enter Tasul. (more…)

UD camera system records sea ice, identifies ideal walrus habitats

About the video: A University of Delaware research team led by Chandra Kambhamettu has developed a novel camera system to map the surface topography of Arctic sea ice, identifying the best “homes” for walrus.

Walrus use sea ice as a reproductive, migration and resting habitat. However, as sea ice melts and recedes, this marine mammal increasingly is threatened. (more…)

ANCHORAGE, Alaska – The USGS Alaska Science Center has released new high-resolution video of Pacific walruses hauling out near Point Lay, Alaska, in late August, 2011.

Also available on the USGS Alaska Science Center walrus website are animations of the walruses’ movements as tracked by radio transmitters, and FAQs on the ongoing walrus studies. (more…)

ANCHORAGE, Alaska — USGS Alaska Science Center researchers, in cooperation with the Native Village of Point Lay, will attempt to attach 35 satellite radio-tags to walruses on the northwestern Alaska coast in August as part of their ongoing study of how the Pacific walrus are responding to reduced sea ice conditions in late summer and fall.
