Sounding an Alarm on the West Coast, April 12

The ocean chemistry along the West Coast of North America is changing rapidly because of global carbon dioxide emissions, and the governments of Oregon, California, Washington and British Columbia can take actions now to offset and mitigate the effects of these changes. That is the conclusion of a 20-member panel of leading West Coast ocean scientists, who presented a comprehensive report on April 4 outlining a series of recommendations to address the increase in ocean acidification and hypoxia, or extremely low oxygen levels. “Ocean acidification is a global problem that is having a disproportionate impact on productive West Coast ecosystems,” said Francis Chan, an Oregon State University marine ecologist and co-chair of the West Coast Ocean Acidification and Hypoxia Science Panel. “There has been an attitude that there is not much we can do about this locally, but that just isn’t true. A lot of the solutions will come locally and through coordinated regional efforts.” Ocean acidification and hypoxia are distinct phenomena that trigger a wide range of effects on marine ecosystems. They frequently occur together and represent two important facets of global ocean changes that have important implications for Oregon’s coastal oceans.
