Changes in the Wind

Melting glaciers and crumbling ice sheets are contributing to sea-level rise across the globe, says Oregon State geologist Peter Clark.

Acidification Likely to Intensify

West coast waters are likely to see continued impacts from acidification, warming temperatures and low-oxygen conditions. That’s the conclusion of a report in the journal BioScience co-authored by Francis Chan in the Oregon State College of Science.

Acidic Seawater Threatens Shellfish

The Pacific Northwest, famous for its delectable fried oysters and succulent steamed clams, is one of several coastal “hot spots” where shellfish are subject to “acidification” — seawater whose chemistry is becoming corrosive because of greenhouse gases.

Oysters on Acid

George Waldbusser, a biogeochemist in the College of Earth, Ocean, and Atmospheric Sciences, and Elizabeth Brunner, a master’s student, conducted an experiment with oyster larvae, which are about the width of a human hair.
