Seeking to understand the impacts of environmental stressors on Pacific oysters is the driving force behind a years-long research project involving scientists from the University of Washington and NOAA, and in collaboration with the oyster industry. Critical in aquaculture, Pacific oysters are the dominant oyster species grown on the US West Coast, with the industry in the Pacific Northwest alone valued at over $270 million a year.

A new video features how genetic metabarcoding is being used by the UW Whale And Dolphin Ecology Lab, led by Amy Van Cise, to understand and conserve southern resident killer whales in the Salish Sea.

Each year, polar bears cycle through periods of intense feasting and prolonged fasting. For reproductive females, seasonal bulking is crucial – it fuels the winter denning and fasting period when they give birth. And when they emerge in spring, it gives biologists a chance to assess populations. A new study led by Sarah Teman explores whether A1c could reveal if a polar bear had recently denned, which – combined with the absence of cubs – may signal reproductive failure.

Building community among the different student groups at SAFS and Marine Biology—undergraduates, graduates and postdocs—the SAFS Undergrad Community Building Event was held was held for the fourth year running. Taking place on 13 May, undergraduates were invited to walk around and speak to grads and postdocs about different topics including grad school, what life looks like after graduation, and finding your way in science.

What brought a group of high schoolers to SAFS to teach a lesson on Pacific salmon and chemicals? It all started with an interest in ecology in 9th grade biology class, and a quest to find a relevant, local topic that they could base a research project on. Since then, Iris Zhang, Ivy Wei and Sylvia Mei from Redmond High School worked with Amirah Casey to research the topic, and developed a SEAS lesson centered on the effects of 6PPD-quinone on salmon.

Returning for another successful year on Saturday 17 May, the UW Aquatic Sciences Open House had more than 1,000 attendees, with children of all ages plus their families. Organized by Students Explore Aquatic Sciences (SEAS), the event showcases the breadth of aquatic science taking place at the University of Washington and in the Puget Sound region with partner organizations.

During low tide at Padilla Bay on a bright day in early May, you could find a class of UW undergraduates exploring the largest contiguous seagrass ecosystem in the lower 48. Why? To collect data to assess the habitat value of seagrass.

Congratulations to the four recipients of the SAFS Faculty Merit Award, awarded to outstanding scholars and members of the SAFS community: Emma Meyer (BS), Liz Allyn (MS), Amelia DuVall (PhD), and Kristin Privitera-Johnson (PhD).

In a time of increasing calls for Washington judges to adjudicate water conflicts that reflect the State’s growth and development, two members of the University of Washington School of Aquatic and Fishery Sciences attended the Judicial Education Workshop on Water Resource Science, held on March 28, 2025, at Washington State University (WSU). Angela Dillon, a PhD student at SAFS, gave the judges an overview of the importance of water for the environment and fish, with an emphasis on salmon and the Electron Dam on the Puyallup River, while SAFS Professor, Mark Scheuerell, gave a tour of Lower Granite Dam on the Snake River, held on March 29. 

Bleaching. This complicated and foreboding term now lurks around every conversation about coral reefs. Impacted heavily by climate change and associated warming oceans, coral reefs experience bleaching when the algae that live in their tissues and contribute vitally to their growth are expelled, causing the corals to lose their color, and possibly their lives. Callum Backstrom, SAFS PhD student and one of UW’s 2025 Husky 100, is studying the resilience of certain corals to bleaching.
