Coral reefs are retreating from equatorial waters and establishing new reefs in more temperate regions, according to new research published July 4 in the journal Marine Ecology Progress Series. The researchers found that the number of young corals on tropical reefs has declined by 85% — and doubled on subtropical reefs — during the last four decades.

The six months since we published the previous issue of the newsletter have been exhilarating, exhausting, and just plain amazing as I hope you will see from these articles.

Just beyond where conventional scuba divers can go is an area of the ocean that still is largely unexplored. In waters this deep — about 100 to at least 500 feet below the surface — little to no light breaks through.

“Art and science collide magnificently in this monumental three-volume celebration of the 260 species of fishes that infuse the inland marine waters of Washington State and British Columbia, with hidden beauty, remarkable diversity and intriguing ways of living. This long-awaited work is a must-have not just for serious scientists and devotees of exquisite natural history artistry, but for any and all who find joy in exploring the wonders of nature.”―Sylvia Earle, National Geographic Explorer in Residence, Founder, Mission Blue

Hundreds of harbor seals live in Iliamna Lake, the largest body of freshwater in Alaska and one of the most productive systems for sockeye salmon in the Bristol Bay region. These lake seals are a robust yet highly unusual and cryptic posse. Although how the seals first colonized the lake remains a mystery, it is thought that sometime in the distant past, a handful of harbor seals likely migrated from the ocean more than 50 miles (80 kilometers) upriver to the lake, where they eventually grew to a consistent group of about 400. These animals are important for Alaska Native subsistence hunting, and hold a top spot in the lake’s diverse food web.

Coral reefs typically evoke clear, turquoise waters and a staggering number of colorful fishes. But what supports such an abundance of life?

Chemical signatures imprinted on tiny stones that form inside the ears of fish show that two of Alaska’s most productive salmon populations, and the fisheries they support, depend on the entire watershed.

On May 4th, the University of Washington held its second annual Aquatic Science Open House. Seattle-area families, students, and teachers were invited to explore the institution’s marine and freshwater science programs and interact with researchers. The event was organized by the Students Explore Aquatic Sciences (SEAS) outreach group based in the School of Aquatic and Fishery Sciences (SAFS) and the Academic and Recreational Graduate Oceanographers (ARGO) outreach group based in the School of Oceanography.

Just over one-third of the world’s 246 longest rivers remain free-flowing, according to a new study published May 8 in Nature. Dams and reservoirs are drastically reducing the diverse benefits that healthy rivers provide to people and nature across the globe.

We are proud and thrilled to share the news that School of Aquatic and Fishery Science faculty member Dr. Jacqueline Padilla-Gamiño has been selected by the Latino Center for Health at UW to be recognized at the Latinx Faculty Recognition Event. This annual event honors the scholarly achievements of Latina and Latino faculty across the tri-campuses of the University of Washington for the academic year 2018-2019.
