Could tire discovery go beyond impacts on coho?

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 …

Do we know enough to do anything about all the seals and sea lions in Puget Sound?

Scientists have known for years that Chinook salmon are important to southern resident orcas, but Chinook are not the only fish the whales eat. At the moment, chum salmon are returning to Puget Sound, and recent orca sightings suggest that the whales may now be feeding on chum. Harbor seals also eat Chinook salmon, but …

Time to spare? Why not conduct some real online research to advance science

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 …

Orca report cover

Social scientists analyze public reactions to orca crisis

Social scientists at Oregon State University have been analyzing a trove of more than 17,000 public comments sent to the Washington state governor’s southern resident orca recovery task force. The researchers have added the comments to a keyword database to look at public emotions and perceptions around the issue of orca declines. The orca task …

New report describes anticipated climate-change effects in Washington state

Early effects of a warming Earth have reached Washington state, as we can see from actual measurements. Annual snowpack is declining in the mountains; ancient glaciers are shrinking; sea levels are rising; and coastal waters are becoming less hospitable to sea life. These are some of the changes outlined in a new easy-to-read briefing report …

Sharing info, as changes in ocean chemistry affect Northwest waters at alarming pace

It was fairly alarming, even to scientists, to hear the latest research regarding ocean acidification — a powerful change in ocean chemistry that results from excess carbon dioxide passing from the atmosphere into the oceans of the world. One of the most alarming reports came from Richard Feely, senior scientist at NOAA’s Pacific Marine Environmental …
