Dispatches: Ancient DNA reveals ecological history

Occasionally, this space includes reports and essays from guest writers on the subject of Puget Sound ecosystem recovery. Social scientist Whitney Fleming has this dispatch on new findings that are being revealed by ancient sources. Archaeologists are looking at ancient DNA combined with oral histories to determine ecological conditions from the past.  By Whitney Fleming […]

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 […]

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 […]
