The Fishery Performance Indicators are the most comprehensive, global tool that considers social factors in addition to the usual biological measures when gauging a fishery’s health.

Researchers at the University of Washington’s Friday Harbor Laboratories are looking at how the biomechanics of clingfish could be helpful in designing devices and instruments to be used in surgery and even to tag and track whales in the ocean.

A team of researchers has evaluated fishery improvement projects, which are designed to bring seafood from wild fisheries to the certified market while promising sustainability in the future. In a policy paper appearing May 1 in Science, they conclude these projects need to be fine tuned to ensure that fisheries are delivering on their promises.

UW glaciologists were part of a team that used a new Antarctic ice core to discover which region triggered sudden global-scale climate shifts during the last ice age.

Teasing out how slow, silent earthquakes respond to tidal forces lets researchers calculate the friction inside the fault, which could help understand when and how the more hazardous earthquakes occur.

A patch of warm water off the West Coast, nicknamed “the blob” by a UW scientist, is part of a larger shift in the Pacific Ocean that may be responsible for widespread weather changes.

A new study finds the economic value of enjoying urban birds to be $120 million each year for Seattle residents and $70 million for people living in Berlin. Residents in both cities spend more than the average U.S. adult on bird-supporting activities, which then benefit the local economies as residents invest in bird food and conservation.

A new study implicates fishing in the collapse of forage fish stocks and recommends risk-based management tools that would track a fishery’s numbers and suspend fishing when necessary.

The University of Washington and NASA are preparing for an effort next winter to measure rain in America’s rainiest place: Washington’s Olympic Peninsula. As part of the current gear-up phase, they are looking for volunteers to help track rain.

A UW geologist and geotechnical engineer look back at what the past year has meant, personally and professionally, as they helped recovery efforts from the nation’s deadliest landslide in our own backyard.

A University of Washington scientist is lead author on the first census of all Arctic marine mammals, including whales, walruses, seals and polar bears. The multinational report assesses the current status of these populations and makes recommendations for conservation of these species under climate change.

For more than 100 years, marine biologists at Friday Harbor Laboratories have studied the ecology of everything from tiny marine plants to giant sea stars. Now, as the oceans are undergoing a historic shift in chemistry, the lab is establishing itself as a place to study what that will mean for marine life. And the University of Washington laboratory is uniquely placed in naturally acidic waters that may be some of the first pushed over the edge by human-generated carbon…

Two University of Washington professors argue in a Science perspectives article that ecosystem managers must learn to make decisions based on an uncertain future.

A UW atmospheric scientist is leading a six-week survey of eastern U.S. skies to see how winter conditions affect air quality.

Some of the oldest rocks on the planet push back scientific estimates of when life could have covered the Earth by 1 billion years.

The first early earthquake warning system for the region has begun testing with a small group of users at businesses and public agencies in Washington, Oregon and British Columbia.

On the anniversary of a massive earthquake off our region’s coast, UW researchers are working on everything from tsunami evacuation structures to updated seismic hazard maps.

A UW researcher is chief scientist this month on a project to drill the first deep ice core at the South Pole, to understand the climate history in that section of Antarctica.

University of Washington scientists published the first large-scale survey of impurities in North American snow. An almost 10,000-mile road trip showed that disturbed soil often mattered as much as air pollution for the whiteness of the snow.

Scientists with the Pacific Northwest Seismic Network will install instruments this Thursday to provide real-time monitoring of the stadium’s movement during the 2015 NFL playoffs. It’s a valuable test of their newest seismic technology.

Many of the worst West Coast winter floods involve heavy rains and melting snow, and UW hydrology experts are using the physics of these events to better predict the risks.

Water off Washington’s coast is warming a third of a mile down, where seafloor methane shifts from a frozen solid to a gas. Calculations suggest ocean warming is already releasing significant methane offshore of Alaska to California.

Surprisingly, the diversity of birds in suburban areas can be greater than in forested areas, according to John Marzluff’s new book “Welcome to Subirdia.”

Scientists using a microbe that occurs naturally in eastern cottonwood trees have boosted the ability of willow and lawn grass to withstand the withering effects of the nasty industrial pollutant phenanthrene.

Instead of carbon dioxide, or CO2, creating a blanket that slowly warms the planet, long-term warming happens because a darker surface and more moist air can absorb more of the incoming rays.

Undergraduates this week were among the first people to try the latest in seafloor mapping technology — and use it to image a shipwreck on Seattle’s urban lake.

More diverse voices could help break a deadlock gripping the conservation community, say 238 co-signatories – including a dozen from the University of Washington.

Freshwater fish with bellies full of shrews – one trout a few years back was found to have eaten 19 – aren’t as random as scientists have thought.

UW scientists worked with managers of federal parks and forests to come up with a strategy to address warmer temperatures, increased wildfires and more flooding in the North Cascades region.

A state-of-the-art imaging machine is coming to the University of Washington for use by researchers in a variety of disciplines.

Better integration of citizen science into professional science is a growing consideration at the UW and elsewhere.

Tiny animals migrating from the ocean’s surface to the sunless depths helps shape our oceans. During the daylight hours below the surface the animals release ammonia, the equivalent of our urine, that plays a significant role in marine chemistry, particularly in low-oxygen zones.

Geologists have long debated when and how the Tibetan Plateau reached a 14,000-foot-plus elevation, but new UW-led research shows it once was probably even higher.

Through new degree programs starting this fall, students will learn architecture from a liberal arts perspective, complete social sciences degrees online, become expert in the teaching of science, and much more.

UW students have had a unique experience off the coast of Washington and Oregon helping scientists and engineers complete construction of the world’s largest deep-ocean observatory.

Floating sensors built at the UW will be central to a new $21 million effort to learn how the ocean surrounding Antarctica influences climate.

The number of California blue whales has rebounded to near historical levels and, while the number of blue whales struck by ships is likely above allowable U.S. limits, such strikes do not immediately threaten that recovery.

Better understanding of how a deadly algae grows offshore and gets carried to Pacific Northwest beaches has led to a computer model that can predict when the unseen threat will hit local beaches.

One of Arizona’s largest watersheds – home to many native species of fish already threatened by extinction – is providing a grim snapshot of what could happen to watersheds and fish in arid areas around the world as climate warming occurs.
