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.

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, 91探花researchers teamed up with NASA scientists to show that the interior is likely composed of slushy layers instead.

鈥淭he Memory of Darkness, Light and Ice鈥 鈥 a documentary film featuring Eric Steig, a 91探花professor of Earth and space sciences 鈥 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.

A new collaborative study led by scientists at the 91探花 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.

A new analysis of data from the Cassini space probe has identified organic compounds within jets of water ice erupting from Saturn鈥檚 moon Enceladus. Some of the compounds, which likely originated in Enceladus鈥 subsurface ocean, have never before been identified on another world beyond Earth. The study, conducted in part by a 91探花researcher, contributes to mounting evidence that Enceladus could support life.

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 鈥 without getting too close 鈥 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.

Some of the most dramatic climatic events in our planet鈥檚 history are 鈥淪nowball Earth鈥 events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles thick. New research from the 91探花 provides a more complete picture for how the last Snowball Earth event ended, and suggests why it preceded a dramatic expansion of life on Earth, including the emergence of the first animals.

Could life be found in frozen sea spray emitted from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, this life should be detectable by instruments launching in the fall.

New research documents the fastest-known large-scale breakage along an Antarctic ice shelf. In 2012, a 6.5-mile crack formed in about 5 and a half minutes, showing that ice shelves can effectively shatter, though the speed of breakage is reduced by seawater rushing in. These results can help improve ice-sheet models and projections for future sea level rise.

Three new faculty books from the 91探花 cover wide-ranging topics: life in the Rio Grande Valley, fossils of Washington state and the colonial roots of contemporary intersex medicine. 91探花News talked with the authors to learn more. Collection highlights life in Rio Grande Valley 鈥淧uro Pinche True Fictions鈥 is a collection of short stories and comics from Jos茅 Alaniz, professor of Slavic languages and literature at the UW. The works are mostly set in the Rio Grande Valley…

An international team including a 91探花scientist found that the water on one of Saturn鈥檚 moons harbors phosphates, a key building block of life. The team used data from NASA鈥檚 Cassini space mission to detect evidence of phosphates in particles ejected from the ice-covered global ocean of Saturn鈥檚 moon Enceladus.

Scientists suspect that the red streaks crossing the surface of Jupiter’s moon Europa is a frozen mixture of water and salts, but its chemical signature matches no known substance on Earth. Now researchers have discovered a new type of solid crystal that forms when water and table salt combine in cold, pressurized conditions. Researchers believe the new substance created in a lab on Earth could form at the surface and bottom of these worlds鈥 deep oceans.

UW’s Virtual Field Geology project has many goals: to make geology field experiences accessible to more people; to document geological field sites that may be at risk from erosion or development; to offer virtual 鈥渄ry run鈥 experiences; and to allow scientific collaborators to do virtual visits to a field site together.聽While the pandemic brought new urgency to the project, its developers believe it’s part of a “new normal” for geology research and education.

A 2018 expedition that drilled farther into the seafloor than ever before — almost 2 miles — sought to take measurements of stress as close as possible to a tectonic fault off the coast of Japan. Surprisingly, the researchers found little built-up tectonic stress. The findings could help to better understand earthquakes in subduction zones around the world.

A 91探花 pilot project is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring. Funded in part with a $473,000 grant from the M.J. Murdock Charitable Trust, a nonprofit based in Vancouver, Washington, the new 91探花Photonic Sensing Facility will use photons traveling through a fiber-optic cable to detect ground motions as small as 1 nanometer.

As glaciers worldwide retreat due to climate change, managers of national parks need to know what鈥檚 on the horizon to prepare for the future. A new study from the 91探花 and the National Park Service measures 38 years of change for glaciers in Kenai Fjords National Park south of Anchorage. The study, published Aug. 5 in The Journal of Glaciology, finds that 13 of the 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which glacier types are disappearing fastest.

An experiment conducted on 10 farms across the U.S. suggests that crops from farms following soil-friendly practices for at least five years have a healthier nutritional profile than the same crops grown on neighboring, conventional farms. Researchers believe soil microbes and fungi boost certain beneficial minerals, vitamins and phytochemicals in the crops.
