Scientists recommend immediate plan to combat changes to West Coast seawater chemistry

Marine shelled organisms in Washington are already having difficulty forming their protective outer shells, and the local shellfish industry is seeing high mortality rates in early life stages of some commercially important shellfish species when shell formation is critical.

Global carbon dioxide emissions are triggering troubling changes to ocean chemistry along the West Coast that require immediate, decisive actions to combat through a coordinated regional approach, a panel of scientific experts has unanimously concluded. A failure to adequately respond to this fundamental change in seawater chemistry, known as ocean acidification, is anticipated to have devastating ecological consequences for the West Coast in the decades to come, the 20-member West Coast Ocean Acidification and Hypoxia (OAH) Science Panel warned in a comprehensive report unveiled April 4.
