A new study led by the University of Washington found that while dead whales are valuable sources of fat and protein for some polar bears, this resource will likely not be enough to sustain most bear populations in the future when the Arctic becomes ice-free in summers.
A new analysis that uses high-resolution data for 24 ocean regions in Africa, Europe, North and South America and Australasia shows that 14 percent of the overall seafloor shallower than 1,000 meters (3,280 feet) is trawled. The paper shows that the footprint of bottom-trawl fishing on continental shelves and slopes across the world’s oceans often has been substantially overestimated.
Harold Tobin, who joins the UW this fall as a faculty member in Earth and space sciences and director of the regional seismic sensing network, discusses earthquake early warning, seismic risks and the Pacific Northwest’s “big one.”
Washington state climatologist Nick Bond explains what our upcoming El Niño winter means for the Pacific Northwest.
Former Interior Secretary Sally Jewell brings a lifetime of experience in business, nonprofits, government and the outdoors to the University of Washington, where one of her tasks is to help shape the future of EarthLab, a new university-wide institute that seeks to connect scholars with community partners to solve our most difficult environmental problems.
For more than 2 million years, the native forests on the Pacific islands of Guam and Rota were home to several thousand crows, members of a species found nowhere else on Earth. But over the last 60 years, the Mariana crow — called the Aga in the Chamorro language — has completely disappeared from the island of Guam and rapidly declined on neighboring Rota. Today there are only about 175 Aga left in the wild. To ensure the survival…
The National Science Foundation will support a state-of-the-art marine facility that continues delivering data and new insight to the ocean science community, policymakers and the public worldwide.
Rapid deoxygenation in the Gulf of St. Lawrence is caused by shifts in two of the ocean’s most powerful currents: the Gulf Stream and the Labrador Current. A detailed model shows that large-scale climate change is causing oxygen to drop in the deeper parts of this biologically rich waterway.
The assistant state climatologist, Karin Bumbaco, looks back on an unusually hot and dry summer — the third-hottest summer that Washington state has experienced since 1895.
Two UW polar scientists were among a dozen experts who advised NASA on its upcoming ICESat-2 mission to monitor the 3D surface of the Earth. The mission is scheduled to launch Sept. 15 from California.
Evidence left by a volcano under the ice sheet suggests that the observed bulging of ice in West Antarctica is a short-term feature that may not affect the glacier’s motion over the long term.
University of Washington researchers have found policies are shifting toward restoration projects that include input from more groups and offer a range of benefits to Puget Sound, including flood control, salmon recovery, recreation and habitat protection.
Meticulously tracking of 423 species before, during and after the worst droughts to hit California in more than a thousand years shows surprising patterns. Key prey species plummeted in the third year of the drought, and carnivores were hardest hit in later years.
A new study led by the University of Washington uses data gathered by floating drones in the Southern Ocean over past winters to learn how much carbon dioxide is transferred by the surrounding seas. Results show that in winter the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide than previously believed.
Forest biologist and University of Washington professor David Peterson explains which natural materials burn hotter and faster during a wildfire, what homeowners can do to protect their properties and how climate change is impacting the fire season.
A team led by the University of Washington has created an environmentally friendly way to remove color from dyes in water in a matter of seconds.
A University of Washington report provides the best projections yet for sea-level rise due to climate change at 171 sites along Washington’s coasts.
Observations over the eastern U.S. show why emissions reductions haven’t achieved the same results in winter as they have in summer.
New research suggests the Atlantic Ocean is transitioning back to its slower phase, which means average global air temperatures will go back to rising more quickly.
Regions of Arctic water are becoming ice-free in late summer and early fall. A new study is the first to consider potential impacts on the marine mammals that use this region and identify which populations will be the most vulnerable to ships.
More than 100 scientists and crew from more than 20 U.S. research institutions, including the UW, will depart in August for a month-long expedition to study how the ocean absorbs carbon from the atmosphere.
Tracking of two great white sharks reveals for the first time that in the open ocean they spend more time deep inside warm-water eddies.
A new analysis suggests the value of structured research programs for undergraduates extends to society as a whole by encouraging participants to seek advanced degrees in scientific and technological fields.
Anchovies, herring, sardines and other forage fish play an essential role in the food web as prey for seabirds, marine mammals and larger fish like salmon. When ground into fishmeal and oil, they are also a key food source for farmed seafood and land-based livestock such as pigs and poultry. As seafood consumption outpaces the growth of other food sectors and continues to grow worldwide, farmed seafood — also called aquaculture — has increased rapidly to meet consumer demand. That…
A study of global maize production in 2100 shows dramatic increases in the variability of corn yields from one year to the next under climate change, making simultaneous low yields across multiple high-producing regions more likely, which could lead to price hikes and global shortages.
A new study led by the University of Washington considers which food type is more environmentally costly to produce: livestock, farmed seafood or wild-caught fish.
A new University of Washington-led paper pinpoints starvation as the cause of death for hundreds of thousands of Cassin’s auklet seabirds in late 2014 to early 2015.
Twenty-five polar bear hunters in East Greenland were interviewed before the first formal assessment of this subpopulation, one of 19 subpopulations of polar bears in a changing Arctic.
