New study: 2021 heat wave created ‘perfect storm’ for shellfish die-off

Around this time last year, the Pacific Northwest experienced excruciating, record-breaking heat. With funding from Washington Sea Grant, a team led by the University of Washington has compiled and analyzed hundreds of field observations to produce the first comprehensive report of the impacts of the 2021 heat wave on shellfish.

The results were published online June 20 in the journal Ecology. Read more on UW News here.
