Health assessments planned for two ailing orcas

By Christopher Dunagan Killer whale experts who are not employed by the federal government are preparing to assess the health conditions of two Southern Resident orcas that appear malnourished and may be dying. Any decisions regarding potential medical treatment would be made later. During a conference call on Tuesday, marine mammal biologists, veterinarians and other […]

The lost tidal forests of Puget Sound

Hundreds of years ago, old-growth cedar and spruce loomed over estuaries and bottom lands throughout Puget Sound, creating what are known as tidal forests. These forests were the Pacific Northwest’s answer to the Everglades — giant spongy swamps with a touch of saltwater that made up some of the finest salmon habitat in the region. […]

The latest numbers on shoreline armoring

By Jeff Rice Washington state has released the latest statistics for Puget Sound’s shoreline armoring Vital Sign, comparing armoring creation and removal in 2017. Those familiar with the Vital Sign will know that the state’s goal is to finally see, by 2020, a net decrease in the length of shoreline armoring throughout Puget Sound. Armoring […]

Debate over water quality standards takes a new turn

Many people thought the issue of regulating toxic chemical discharges into Puget Sound was settled when the federal government forced Washington state to use stricter criteria, but the debate may be underway once again. By Christopher Dunagan An unlikely disagreement between state and federal authorities over water-quality standards has flared up again. Two years ago, […]

Orca task force releases recommendations

By Jeff Rice The governor’s Southern Resident Orca Task Force released its final report and recommendations today, focusing on three key threats to Puget Sound’s endangered orcas: Lack of food, disturbance from noise and vessel traffic, and toxic contaminants. In all, the report makes 36 recommendations for recovering the fast-declining orca population, which now stands at […]

Chemicals from automobile tires suspected in coho deaths

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 […]

Studies show challenges for eelgrass restoration

As critically important eelgrass declines in some parts of Puget Sound, scientists are trying to plant more of it. The health of the ecosystem may be riding on their efforts, but what they are finding is something that farmers have known for thousands of years: Getting something to grow may be harder than you think.

PSI collaborator receives NSF grant to study coho deaths

PSI collaborator Ed Kolodziej has received a $330,000 National Science Foundation grant to expand his research on toxic pollutants in Puget Sound. Kolodziej’s project will identify chemicals in stormwater that are killing coho salmon and endangering some spawning runs. The project includes a collaboration with citizen scientists who will alert project members to salmon die-offs […]
