Minute amounts of copper can make salmon easily eaten by predators, says Washington State University researcher Jenifer McIntyre. McIntyre’s research found that the metal affects salmon’s sense of smell so much that they won’t detect a compound that ordinarily causes them to be still and wary. McIntyre conducted her research at CoEnv-affiliated Big Beef Creek Research Station. Read more here!
The increasing flow of nitrates from human and animal waste into Puget Sound are a boon to algae. And as the algae bloom, they set up the Sound for acidification beyond what global climate change is driving. Read more here.
One Mukilteo resident has been sharing his decades of marine science and policy expertise by volunteering with the Snohomish County Marine Resources Advisory Committee. His day job is an environmental compliance analyst, but in his free time UW alum Lincoln Loehr has helped analyze reams of data from mussels collected along the shoreline, contributing key insights into the pollution patterns in Puget Sound.

A new study in Biology Letters has found that at least one insect has found a use for the increasing abundance of plastic in the ocean — as a place to lay eggs. The increase in abundance of this insect, and the potential effects on plankton, crabs, and other community members, is uncertain. OCEAN‘s Giora Proskurowski is quoted. Read more here.
New research by OCEAN’s Giora Proskurowski shows that wind pushes plastics below the surface of the ocean. This means that the decades of research on trash in the ocean, based on surface skimming, may have vastly underestimated the quantity. Read more here or check out this video!
A new study out in Nature finds that human-emitted aerosols may be largely to blame for the Atlantic Multidecadal Oscillation–and therefore that this apparently cyclical climate phenomenon may be neither multidecadal nor an oscillation. Read a perspective on this article here.
