Annual Sub-Arctic Seas meeting coming to UW, June 15-17

The Ecosystem Studies of Sub-Arctic Seas Program (ESSAS) will hold its 10th Annual Science Meeting in Seattle over three days, beginning June 15. Cosponsored by the College of the Environment, and in coordination with the Future of Ice Initiative, the meeting will feature several speakers who will address topics associated with the ecosystem changes being documented or predicted in the Arctic and sub-Arctic, and the effects those are having on people and economies connected to the region.

Antarctic ice core shows northern trigger for ice age climate shifts

University of Washington scientists in the Department of Earth and Space Sciences were part of a multi-institutional research team that has discovered a consistent link between abrupt temperature changes in Greenland and Antarctica during the most recent ice age. Using evidence trapped in ice cores from the West Antarctica Ice Sheet, the team from UW used analyses of oxygen molecules in the ice to uncover precise records of Antarctica’s temperature history.

UW scientist leads multinational study on the future of Arctic marine mammals

Aquatic and Fishery Sciences’ Kristin Laidre and a team from across the globe just published their findings on what the future looks like for Arctic marine mammals, whose fragile habitats are shifting as a result of sea ice loss and warming temperatures. Their recent study, published in Conservation Biology, found that reductions in sea ice cover are “profound” and that the Arctic’s traditionally short, cool summers are growing longer in most regions by five to 10 weeks.

Imaging the Arctic

Imaging the Arctic is an interdisciplinary project and exhibition that explores the ecology and culture of West Greenland through the work of University of Washington marine mammal biologist Kristin Laidre, expeditionary artist Maria Coryell-Martin, Finnish photographer Tiina Itkonen, and graphic novelist Owen Curtsinger. The project is oriented around Laidre’s research on the impact of climate change in the Arctic, and sea ice loss on narwhals and polar bears.

UW-built sensors to probe Antarctica’s Southern Ocean

The Southern Ocean plays a major role in taking carbon from our atmosphere and storing it in the ocean. Yet the finer points of what makes these waters so good at doing that are not well known. Notoriously dangerous seas, the Southern Ocean — which surrounds Antarctica — have historically been difficult for scientist to access and study. College of the Environment oceanographers are set to help change that as one of 10 partner institutions in a new National Science Foundation study.
