In a new study, University of Washington researchers examine the impact of tilling on soil moisture and water retention using methods designed for monitoring earthquakes. They show that tilling disrupts important soil microstructures and highlight the potential utility of this method for precision agriculture and more.

A new study examining 13 years of ground motion data from sites near the Cascadia Subduction Zone shows that the entirety of the fault may not be as tightly locked as researchers thought, which could change our understanding of how a big earthquake might hit the Pacific Northwest.

Jennifer Ruesink, University of Washington professor of biology, studies the relationship between the environment and marine organisms, including eelgrass, the primary species of seagrass that resides in the oceans surrounding Washington. In honor of World Seagrass Day, UW News asked Ruesink to explain what seagrass is and what makes the seagrasses in Washington unique.

More than a decade ago, data from the Cassini mission to Saturn suggested that the planet’s largest moon, Titan, had a vast ocean of liquid water below its frozen surface. In a new study, UW researchers teamed up with NASA scientists to show that the interior is likely composed of slushy layers instead.

“The Memory of Darkness, Light and Ice” — a documentary film featuring Eric Steig, a UW professor of Earth and space sciences — tells the story of a U.S. military and research base established in Greenland during the Cold War, and how the samples collected there are driving modern climate science. The film is now available on YouTube, Apple TV and Amazon Prime.

University of Washington researchers analyzed data collected in the decade following the Paris Agreement, an international treaty signed in 2015 to limit warming by cutting emissions. The treaty has helped nations reduce the amount of carbon released per dollar, but emissions are still too high due to global economic growth.

A new collaborative study led by scientists at the University of Washington and the University of Maryland Center for Environmental Science proposes that a tsunami struck the Caribbean island of Anegada between 1381 and 1391, carrying huge coral boulders inland and leaving behind a valuable record of geologic and climatic history.

In a new study, a team of scientists determined the minimum natural habitat on agricultural land that will allow insect pollinators — including bumble bees, solitary bees, hoverflies and butterflies — to thrive. UW News reached out to co-author Berry Brosi, UW professor of biology, to learn more about these results and how habitat is important to two types of bees native to Washington.

Bee experts wouldn’t have previously expected to find the likes of Osmia cyaneonitens, Dufourea dilatipes and Stelis heronae in Washington. But this year, while collecting pollinators in Chelan County to study how climate and wildfires affect native bee populations, Autumn Maust, a University of Washington research scientist of biology, discovered eight bee species never recorded in Washington.

New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads, lining a cartilaginous appendage called the tenaculum, in addition to those in their jaws. They used their tenaculum teeth to grip females while mating in water.

The University of Washington’s College of the Environment will expand its work related to climate solutions thanks to a grant announced today from Fund for Science and Technology, FFST, a new foundation within the Paul G. Allen philanthropic ecosystem.

A UW-led team of researchers used a fiber-optic cable to capture calving dynamics across the fjord of the Eqalorutsit Kangilliit Sermiat glacier in South Greenland. This allowed them to document — without getting too close — one of the key processes that is accelerating the rate of glacial mass loss and in turn, threatening the stability of ice sheets, with consequences for global ocean currents and local ecosystems.

Kendall Valentine, an assistant professor of oceanography at University of Washington, along with collaborators from the University of Rhode Island and the Desert Research Institute are traveling to Anchorage and the Copper River Delta to study marshes that formed in the years following the 1964 earthquake.

A new University of Washington–led study projects that in the next 35 years increasing boreal fires will actually slow global warming by 12% globally and 38% in the Arctic. Because the aerosols in smoke reflect more sunlight and make clouds brighter, summer temperatures during fire season drop, leading to reduced sea ice loss and cooler winter temperatures.

A recent theory proposes that whales weren’t just predators in the ocean environment: Nutrients that whales excreted may have provided a key fertilizer to these marine ecosystems. Research led by University of Washington oceanographers finds that whale excrement contains significant amounts of iron, a vital element that is often scarce in ocean ecosystems, and nontoxic forms of copper, another essential nutrient that in some forms can harm life.
