UW oceanographers wire up an undersea volcano to study Earth’s most extreme environment

Several hundred miles off the coast of Oregon and Washington, there’s an undersea volcano known as Axial Seamount. Thanks to a set of high-tech instruments installed last summer by a team of scientists, many from the College of the Environment, the deep sea is online and oceanographers were able to observe an eruption of the Axial Volcano in April 2015. PBS NewsHour’s Hari Sreenivasan recently spoke with the School of Oceanography‘s John Delaney and Debbie Kelley about their team’s deep sea observatory, including a network of sensors, moorings, and cameras that collect troves of new information about this underwater world.

What does it take to catalogue every glacier in a mountain range?

After days of waiting around in Port Angeles, Washington, Earth and Space Sciences’ T.J. Fudge finally got some good news: a helicopter would be able to drop him and another researcher into the wilderness of Olympic National Park. Fudge didn’t know it yet, but nasty weather would prevent the helicopter from returning to pick them up, leaving the scientists no choice but to hike out.

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.
