These frozen moons are not dead

Moons get no respect. People think of them as dead and cold, often overshadowed (literally) by the superstar planets they orbit around. But planetary scientist Baptiste Journaux would disagree. He’s fascinated by moons and the growing research that has shown that moons are far more active than we used to think. In fact, they contain heat and ice and essential components needed for life. Pocket Science host Gabriel Spitzer talks with Journaux about the latest discoveries of frozen planets and the upcoming NASA mission to explore Titan, the moon orbiting Saturn.

Seismic sensors track fan-generated activity during World Cup games at Seattle Stadium

The Pacific Northwest Seismic Network (PNSN) installed seismic sensors designed to record the ground shaking throughout Seattle Stadium, as Seattle hosts guests from all around the world for the 2026 FIFA World Cup games.

Highlights from the 2026 ESS Research Symposium and Gala

The UW Department of Earth & Space Sciences Research Symposium and Gala is an annual graduate student-organized event that brings together students, faculty, alumni and supporters to celebrate our students’ groundbreaking work. This year’s Gala, held during the first week of Spring Quarter, showcased over 30 student presentations, 17 posters, a department-wide photo contest and an awards reception.

UW earthquake sensors capture World Cup excitement

The Pacific Northwest Seismic Network, housed within the UW Department of Earth and Space Sciences, is once again using its earthquake-sensing equipment to connect with sports fans. As Seattle hosts FIFA World Cup matches over the next few weeks, PNSN will use some of the same seismometers that provide early warning for earthquakes to track the excitement and energy of the crowds.

ESS undergrad researcher studies some of Earth’s oldest ice

When the opportunity arose to work with 5 million-year-old ice from Antarctica, Hailey Smith jumped at the chance. Smith, a fourth-year ESS undergraduate student, had spent the past year working with ESS graduate student mentor Liam Kirkpatrick on a research project to decipher the origins of layering in ice core segments from Antarctica. These ice cores give us insights into atmospheric conditions millions of years ago.

This work builds on a method Kirkpatrick developed with advisors T.J. Fudge and Eric Steig that uses 3-D electrical conductivity mapping, along with isotope measurements, to reveal centimeter-scale changes in ice composition, giving Smith hands-on exposure to cutting-edge geoscience research.

Smith and Kirkpatrick were paired as a research team through their involvement with the UW College of the Environment's Identity, Belonging and Inquiry in Science (IBIS) mentoring program that connects undergraduate students interested in research with graduate student mentors in the geosciences.

Near-catastrophic megatsunami in Alaska prompts reflection on human-caused climate change

UW research scientist Mira Berdahl, along with ESS Professors Eric Steig and Gerard Roe, helped develop a modeling approach showing that the glacier retreat that enabled the Alaska landslide was driven entirely by human-caused climate change rather than natural processes. Berdahl is interviewed.

Earthquake monitoring system not part of federal ocean observatory cuts

Scientists are now warning that scaling back the Ocean Observations Initiative could put Washington and Oregon at risk. However, the cable system managed by the UW Pacific Northwest Seismic Network used for earthquake and tsunami monitoring is not being removed. ESS Professor and PNSN Director Harold Tobin is interviewed.

With ShakeAlert installations complete, researchers explore offshore expansion

PNSN has been hard at work expanding the ShakeAlert seismic monitoring network since the Washington/Oregon launch in 2021.

Now, with all planned installations complete, researchers are celebrating a huge milestone while continuing to explore opportunities. This story describes how including offshore, ocean bottom sensors in the network could improve warning time for a Cascadia Subduction Zone earthquake.
