Last month, PSI staff writer Eric Wagner joined hundreds of scientists from 51 countries to talk about the health of the world’s seabirds. He has this dispatch from the World Seabird Conference in Australia. www.pugetsoundinstitute.org/dispatch-fro...

To kill or not to kill? Proposed federal legislation would allow permits to kill seals and sea lions with the goal of protecting some Puget Sound salmon populations. A new article in Salish Sea Currents magazine explores the debate and the science. tinyurl.com/seals-and-se...

The 15th annual Puget Sound Marine Waters Overview produced by the PSEMP Marine Waters Workgroup is out. In general, 2025 was warmer, drier, saltier, and had less abundant biota. Check out highlights or dive into the details of the new report. www.eopugetsound.org/article/puge...

Case studies of Dungeness crabs, English sole, and Chinook salmon offer new details on when and where these species are most vulnerable to low oxygen in Puget Sound. Tim Essington and Stefano Mazzilli present the findings on 9/10/26 from 10:30 AM to 12:00 PM (PT). washington.zoom.us/meeting/regi...

Now is the time to witness Chinook salmon pass through the Hiram M. Chittenden Locks. It's an extraordinary challenge as they must: Climb the fish ladder Adjust to shifts in temperature, salinity, and oxygen Swim upstream Spawn How do they do it? Hint: ESTUARIES. Learn more. tinyurl.com/salmo…

Fall migration fact: Some Chinook salmon in Puget Sound never leave for the ocean at all! So called “resident” Chinook complete their entire marine life in Puget Sound estuaries near the mouths of rivers that enter Elliott Bay including the Duwamish River. Learn more: tinyurl.com/Chinook-salm...

Early counts from this year's southern resident killer whale census point to an increase of two, pending final confirmation from @whaleresearch.bsky.social, now in its 50th year of tracking the southern resident population. Story in Salish Sea Currents: www.pugetsoundinstitute.org/annual-censu...

Southern resident killer whales don't rest much: a new study finds they forage nearly as much at night as during the day. Females are far less likely to attempt a catch at night than during the day, adding urgency to efforts to reduce daytime vessel noise in the Salish Sea. tinyurl.com/orcasatnight

New on our blog: the human side of ecosystem recovery is essential. PSI's Rob Anderson, co-author on a new paper in Coastal Management, puts it simply: most environmental issues are as much about people and politics as they are about nature itself. www.pugetsoundinstitute.org/how-puget-so...

Tire companies and their chemical suppliers are working overtime to find a safe and effective replacement for the toxic tire additive 6PPD. Our senior writer Christopher Dunagan reports on which companies are in the hunt. www.eopugetsound.org/article/play...

Spring is prime time to spot gray whales in Puget Sound. The Sounders are a small group that breaks off from the Pacific migration each spring to feed in northern Puget Sound—in some of the shallowest waters of any whale on earth. Check out the new profile in the EoPS: tinyurl.com/graywhalessa...

We just declared drought for the fourth year in a row. And this year, it’s statewide.
