Update: A pdf of slides from the presentation is now available. Adequate stream flows are critical to Puget Sound’s endangered salmon and are one of the state’s ‘Vital Sign’ indicators of ecosystem health. Earlier data suggests that summer stream flows have been on the decline, but new analysis shows that gauging these flows may be …
Scientists have suspected for several years that chemicals from tire wear particles are to blame for the deaths of thousands of coho salmon that have returned to spawn in Puget Sound’s urban streams. Sometimes referred to as “pre-spawn mortality” or “urban runoff mortality syndrome,” these deaths typically occur in streams near roads, and scientists have …
Researchers at a non-profit biotech startup in Tacoma have found traces of the novel coronavirus in the city’s sewage, opening up new possibilities for tracking and monitoring the COVID-19 pandemic. The testing is being led by Center for Urban Waters collaborator David Hirschberg who directs the RAIN biotech incubator in Tacoma, along with RAIN’s principal …
If you are looking for something constructive to do in this stay-at-home period of our lives, I might suggest joining a team of scientists conducting real online research. Zooniverse, a clearinghouse of about 100 active crowd-sourced science projects, has added educational materials for all age groups. Students learning at home can assist professional researchers as …
As officials struggle to track and contain the outbreak of the novel coronavirus known as COVID-19, ecologists say widespread impacts from viruses and other pathogens are also a growing threat to the species of the Salish Sea ecosystem. “We’re all especially impressed with how rapidly [COVID-19] emerged, the pace of its spread and how massively …
Puget Sound Institute lead ecosystem ecologist Tessa Francis was quoted in a recent article in UW News. From UWT News Service: “Young herring ‘go with the older fish’ a key finding in Ocean Modeling Forum’s efforts,” by Michelle Ma, UW News, May 29, 2019, http://www.washington.edu/news/2019/05/29/young-herring-go-with-the-older-fish-a-key-finding-in-ocean-modeling-forums-efforts/.

Washington and British Columbia residents are largely unfamiliar with the Salish Sea. A recent study conducted by the SeaDoc Society and Oregon State University reveals a need to improve geographic literacy and familiarity with the Salish Sea among those communities who share and live alongside this integrated transboundary ecosystem. This is a guest blog from …
By Christopher Dunagan After five weeks at sea, a team of 21 scientists from five countries returned Monday with some surprising findings about the mysterious lives of salmon in the Pacific Ocean, according to Laurie Weitkamp, a salmon biologist with NOAA’s Northwest Fisheries Science Center in Newport, Ore. “It was quite an experience,” said Weitkamp, …
This week, our magazine Salish Sea Currents takes an in-depth look at ongoing legislative activity to prevent oil spills in Puget Sound. PSI senior writer Christopher Dunagan reports on the push to adopt new rules to counter-balance the increasing risks of tanker collisions and potential catastrophic spills. Among the concerns: About 1,300 tanker ships, of all types, …
Findings authored this month by University of Washington scientists at the Center for Urban Waters and their collaborators provide new insight into “urban runoff mortality syndrome” affecting Puget Sound coho. By Jeff Rice Chemicals linked to automobile tires have been found in stormwater associated with the widespread deaths of coho salmon in Puget Sound. The …
Ocean acidification could be up to twice as severe in fragile seagrass habitats as it is in the open ocean, according to a study published last month in the Proceedings of the National Academy of Sciences. The conditions may threaten Dungeness crabs by 2050 and will be especially pronounced in the winter, the study says. …
Pacific herring exposed to stormwater in Puget Sound show some of the same effects as fish exposed to major oil spills. Symptoms include heart and developmental problems. Read the story from Katie Keil in our magazine Salish Sea Currents.
