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 study of the auklets that is revealing new information about the health of seabirds in the Salish Sea.

For declining orcas, food is fate

Recent images of a mother orca appearing to grieve for her dead calf have brought worldwide attention to the plight of Puget Sound’s endangered Southern Resident orcas. As orca numbers decline, we look at how the effects of toxic chemicals on the whales are magnified even as the residents slowly starve from a general lack of Chinook salmon, their chief source of food.

Marine survival: New clues emerging in salmon deaths

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. It is uncovering a complex web of problems involving predators, prey and other factors that put salmon at risk as they migrate to the ocean. We present a four-part series on the Salish Sea Marine Survival Project, including new findings presented at the 2018 Salish Sea Ecosystem Conference last spring in Seattle.

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.

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.

Size means survival for young salmon

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 continue our series on the Salish Sea Marine Survival Project with a look at what helps salmon grow and prepare for life in the open ocean.

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. We begin a four-part series on the Salish Sea Marine Survival Project, including new findings presented at the 2018 Salish Sea Ecosystem Conference last spring in Seattle.

New book helps kids discover the Salish Sea

Kids around the region are learning about the Salish Sea thanks to a new book that is being offered — in many cases free of cost — to Washington schools and libraries. Explore the Salish Sea by Joe Gaydos and Audrey Benedict inspires the next generation to appreciate and perhaps someday protect the environment close at hand.

Despite WA ban on farmed salmon, BC impacts may flow across border

A high-profile salmon escape led to a ban on salmon farms in Washington earlier this year. But just across the border, scientists say salmon farms in British Columbia expose migrating fish from Puget Sound to potential maladies like parasites, bacteria and dangerous viruses. They say simply getting rid of salmon farms in Washington does not put the potential impacts to rest.

Ocean acidification may be twice as extreme in Puget Sound’s seagrass habitats, threatening Dungeness crabs

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 April 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.
