Alaska’s coastal waters are particularly vulnerable to ocean acidification because of cold water that can absorb more carbon dioxide, and unique ocean circulation patterns which bring naturally acidic deep ocean waters to the surface.
That’s not a dire prediction linked to climate change. It’s already starting to happen as the ocean gets more acidic. And for the Lowcountry, ocean acidification might not even be the real threat. It might be what scientists call the one-two punch of acidification and low oxygen in the estuaries, the nursery for the shellfish we eat – shrimp, oysters, clams.
