The National Science Foundation has awarded the University of Washington $52.4 million over five years to continue operating the Regional Cabled Array, a cabled deep-ocean observatory about 300 miles offshore from Newport, Oregon. The grant is part of a $220 million total investment that will fund the internet-connected ocean observatory, known as the Ocean Observatories Initiative, through 2028.
Polar scientist Eric Regehr studies polar bears on Wrangel Island, an island off Russia that is home to the highest concentration of polar bears in the world. Regehr and UW glaciologist Ian Joughin will field audience questions after screenings of “Arctic: Our Frozen Planet,” which focuses on the changing Arctic environment.
Researchers dropped technology developed at the University of Washington off the coast of Florida this week to measure ocean waves in the path of Hurricane Ian. The test is one part of a broad effort to improve forecasts for these fast-moving and deadly systems.
A new population of polar bears documented on the southeast coast of Greenland use glacier ice to survive despite limited access to sea ice. This small, genetically distinct group of polar bears could be important to the future of the species in a warming world.
In the past 20 years, the Arctic has lost about one-third of its winter sea ice volume, and winter sea ice in the Arctic has lost about a foot and a half of thickness over just the past three years. This thinning is largely due to loss of older, multiyear sea ice that is more resistant to melting.
Results show that by the end of this century, lower-oxygen water on the Pacific Northwest coast will pose the biggest threat to Dungeness crabs. And while these crabs start as tiny, free-floating larvae, it’s the sharp-clawed adults that will be most vulnerable.
Three separate University of Washington research teams have been awarded $750,000 each by the National Science Foundation to advance studies in misinformation and the ocean economy.
University of Washington glaciologists will join colleagues from around the country in a new effort to retrieve an ice core more than 1 million years old from East Antarctica, to better understand the history of our planet’s climate and predict future changes.
The region north of Greenland and the Canadian Arctic has been termed the Last Ice Area, where sea ice will remain the longest in summertime, providing a refuge for ice-dependent Arctic species. But conditions last summer show that parts of this region are already experiencing less summer ice due to climate change.
Satellite images show that from 2017 to 2020, Pine Island Glacier’s ice shelf lost about one-fifth of its area, mostly in three dramatic breaks. This caused the glacier to speed up by 12%, hastening its downward motion and boosting its contribution to rising seas.
Endangered blue whales are present and singing off the southwest coast of India. The results provide insight into a poorly studied population and suggest conservation measures should include this region.
Leveraging the tectonic laboratory of the Cascadia subduction zone, the University of Washington today announced a new effort to best understand how to study and live with the threats of earthquakes, tsunamis, volcanos, landslides and other seismic hazards. Dubbed the GeoHazards Initiative, the interdisciplinary work aims to develop and promote the adoption of early detection systems both on land and at sea to help prevent the loss of human life and property.
The Arctic Ocean’s Beaufort Sea has increased its freshwater content by 40% over the past two decades. When conditions change this freshwater will travel to the Labrador Sea off Canada, rather than through the wider marine passageways that connect to seas in Northern Europe. This has implications for local marine environments and global ocean circulation.
The small subpopulation of polar bears in Kane Basin were doing better, on average, in recent years than in the 1990s. The bears are experiencing short-term benefits from thinning and shrinking multiyear sea ice that allows more sunlight to reach the ocean surface, which makes the system more ecologically productive.
Loss of ice from Antarctic and Greenland ice sheets since 2003 have contributed 0.55 inches to global sea level rise, with about two thirds coming from Greenland ice. The new, detailed satellite measurements provide a global picture of ice sheet change — and insights into the future of Greenland and Antarctica.
Throughout the month of November 2019, a team of University of Washington researchers chased storms in the Arctic Ocean. The project, Coastal Ocean Dynamics in the Arctic, or CODA, is looking at how water currents shift and waves hit the coast with more open water, to provide better forecasts and predictions for the region’s future.
Satellite tracking of adult females and visual monitoring of polar bears in Baffin Bay show changes from the 1990s to the period from 2009 to 2015. Bears in Baffin Bay are getting thinner and adult females are having fewer cubs than when sea ice was more available.
With 2019 on pace as one of the warmest years on record, a new international study reveals how rapidly the Arctic is warming and examines global consequences of continued polar warming.
A University of Washington team is leaving to study how fall storms, dwindling sea ice and vulnerable coastlines might combine in a changing Arctic.
UW marine scientists are using high-tech tags to record the movements of swordfish — big, deep-water, migratory, open-ocean fish that are poorly studied — and get a window into the ocean depths they inhabit.
This week a UW team is releasing a robotic surfboard to explore the surface ocean around Antarctica.
Two UW researchers — Bonnie Light, a principal physicist at the UW’s Applied Physics Laboratory and an affiliate associate professor of atmospheric sciences, and Madison Smith, a recent UW graduate who is now doing her postdoctoral research at the UW — will join for the fifth of the six two-month legs, in summer 2020.
A new study provides a 110-year record of the total volume of Arctic sea ice, using early U.S. ships’ voyages to verify the earlier part of the record. The longer record puts the recent loss into perspective.
A UW team will visit Alaska’s North Slope Borough the week of April 28 in preparation for a two-year study of how waves, ice loss and warming are affecting the low-lying region.
A team of ocean robots developed at the UW is the first group of self-guided ocean instruments to travel under an ice sheet and come back to report long-term observations.
