"> Nights in the lives of the rhinoceros auklets of Protection Island
More than 70 percent of the seabird population of Puget Sound nests on a single island in the Strait of Juan de Fuca. That includes a massive colony of rhinoceros auklets that has drawn the interest of scientists and birders alike. Our writer Eric Wagner visited the island this summer and reports on a long-term […]

"> Building a library of microplastics in the Salish Sea
By Shannon Black Microplastics are found throughout the Salish Sea, but “surprisingly little is known about the sources of these particles,” report Canadian scientists who presented their findings last spring at the Salish Sea Ecosystem Conference in Seattle. Now the group, led by Dr. Peter Ross at the Vancouver Aquarium is working to categorize the […]

"> For declining orcas, food is fate
The story of Puget Sound’s starving resident orcas has come into dramatic focus over the past two weeks. As the world watches an orca grieve for her dead calf, and tribes and federal agencies prepare to try to feed a dangerously emaciated three-year-old orca in Jpod, we look at how the lack of Chinook salmon […]

"> New studies on emerging threats to salmon
Chemicals, disease and other stressors can increase a salmon’s chance of being eaten or reduce its ability to catch food. We wrap up our series on the Salish Sea Marine Survival Project with a look at some of the lesser-known, but still significant factors contributing to salmon declines in the Salish Sea. Read the story in […]

"> Removal of creosote-treated pilings may assist herring recovery
Thousands of abandoned wood pilings — the ghosts of piers and docks past — are located throughout Puget Sound. Most of them are treated with creosote, a toxic chemical used to preserve wood that contains polycyclic aromatic hydrocarbons (PAHs), a class of chemicals that are also associated with oil spills and burning of fossil fuels. […]

"> Could anchovies and other fish take pressure off salmon and steelhead?
A recent influx of anchovies into Puget Sound may have saved some steelhead from predators, but researchers seek more evidence to prove the connection. Our series on the Salish Sea Marine Survival Project continues with a look at these and other potential impacts from predators on the region’s salmon and steelhead. Read the story in […]

"> Size means survival for young salmon
We’ve published part 2 of Christopher Dunagan’s series on the Salish Sea Marine Survival Project. Getting bigger faster can help save juvenile Chinook salmon from a gauntlet of hungry predators ranging from birds and marine mammals to larger fish. We take a look at what helps salmon grow and prepare for life in the open […]

"> Opening the black box: What’s killing Puget Sound’s salmon and steelhead?
An intensive research program in the U.S. and Canada is studying why so few salmon in the Salish Sea are returning home to spawn. They are uncovering a complex web of problems involving predators, prey and other factors that put salmon at risk as they migrate to the ocean. Puget Sound Institute senior writer Christopher […]
