Using light to hear the whales

Novel research trial uses Distributed Acoustic Sensing technology by repurposing fiber optic cables to monitor Puget Sound's orca population. The co-primary investigators in the project include ESS Assistant Professor Brad Lipovsky and Associate Professor Marine Denolle. As the project expands, opportunities will open for undergraduate students to participate in data analysis and in-the-field experiments.

Coral skeletons left by a medieval tsunami whisper warning for Caribbean region

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.

Mariners fans' cheers cause ground to shake, reach seismic level

The Pacific Northwest Seismic Network measured the intensity of fan energy in Friday's winner-take-all game against the Detroit Tigers. PNSN field engineer Mickey Cassar is quoted.

Link between Cascadia and San Andreas Fault earthquakes discovered 30 years after lost vessel stumbled across key data

Geological records hint that earthquakes at the Cascadia subduction zone might trigger the San Andreas fault. ESS Professor and Pacific Northwest Seismic Network Director Harold Tobin is quoted.

Discovery of organic compounds bolsters case that Saturn's moon Enceladus could support life

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

Major climate change indicators broke records in 2024

Physics Today reports on the BAMS Annual State of the Climate report many broken records for temperature, humidity, glacier melt, and a section written in part by, and quoting Prof. Robert Holzworth's work on lightning climatology.

How a Graham farm helped detect a swarm of earthquakes at Mount Rainier

Explore the crucial role of the Garrison Hill seismic station. PNSN field technician and seismology lab coordinator Doug Gibbons shares how it not only records local earthquake data but also transmits signals from the STAR station on Mount Rainier to the UW PNSN server.

Researchers find key to Antarctic ice loss blowing in the north wind

Antarctic ice is melting at a startling pace, and the West Antarctic Ice Sheet is one of the greatest sources of uncertainty in climate projections. Researchers thought westerly winds were accelerating ice loss, but a new study from UW flips the narrative by 90 degrees, pointing instead to winds from the north. ESS Professor Eric Steig and graduate student Gemma O'Connor are quoted.

An earthquake warning in your hand

Rumblings started underground - and phones lit up. For the first time ever in Washington, ShakeAlert sent real-time warnings just seconds before the shaking began. PNSN Director Harold Tobin is quoted.

Mount Rainier looks less snowy as climate change melts glaciers worldwide

On clear days, when Mt. Rainier is visible from Seattle and Tacoma, locals say "The mountain is out." But lately, melting glaciers have made that iconic view look rockier and less snowy. ESS Associate Research Professor TJ Fudge is quoted.
