A new study from the University of British Columbia has found that artificial turf fields across Metro Vancouver leach 6PPD-quinone, a chemical known to kill coho salmon, into municipal stormwater systems—and the contamination persists long after the fields are installed.

A massive marine heatwave has dominated waters off the West Coast since last summer. This marks only the third time on record that such a large section of the coastal ocean has remained so warm for so long—particularly into winter months—without it being an El Niño, NOAA scientists report.

Canada is failing in a decades-old pledge to monitor the health of Pacific salmon, according to new research from Simon Fraser University. 

Climate change is skewing the North Pacific storm track northwards quicker than current weather predictions have estimated, moving winds and rains closer to the arctic and leaving cooler and drier conditions in the Northwest, according to a recent study published in the journal Nature.

In the aftermath of historically severe wildfires in 2020, a study of Cascade Range watersheds found that stream vertebrates are doing surprising well, highlighted by flourishing fish populations.

In its update to a 2007 climate report, a team of scientists noted that the rate and magnitude of changes in temperature and hydrology in the Columbia River basin has amplified over the past two decades and those changes will impact salmon and steelhead.

A new study led by the Washington Department of Fish and Wildlife’s Toxics Biological Observation System unit explores an unseen threat to the Pacific Northwest’s Chinook salmon -- chemical contamination.

For a century there have been just five places in the continental United States with year-round frozen peaks — all in Washington state. But newly published research documents that these ice-capped summits are changing — melting — faster than many thought possible.
