Polar experiments reveal seasonal cycle in Antarctic sea ice algae

The sea ice off West Antarctica, seen here in October 2018.

In the frigid waters surrounding Antarctica, an unusual seasonal cycle occurs. During winter, from March to October, the sun barely rises. As seawater freezes it rejects salts, creating pockets of extra-salty brine where microbes live in winter. In summer, the sea ice melts under constant daylight, producing warmer, fresher water at the surface. This remote ecosystem is home to much of the Southern Ocean’s photosynthetic life.

The University of Washington is a lead partner on a new multi-institution earthquake research center based at the University of Oregon that the National Science Foundation announced Sept. 8 will receive $15 million over five years to study the Cascadia subduction zone and bolster earthquake preparedness in the Pacific Northwest and beyond. The Cascadia Region Earthquake Science Center, or CRESCENT, will be the first center of its kind in the nation focused on earthquakes at subduction zones, where one tectonic plate slides beneath another.

Study connects greenhouse gas emissions to polar bear population declines, enabling greater protections under Endangered Species Act

A polar bear looks into the camera lens

New research from the University of Washington and Polar Bears International in Bozeman, Montana, quantifies the relationship between greenhouse gas emissions and the survival of polar bear populations. The paper, published online Aug. 31 in Science, combines past research and new analysis to provide a quantitative link between greenhouse gas emissions and polar bear survival rates. A warming Arctic is limiting polar bears’ access to sea ice, which the bears use as a hunting platform.
