West Coast

The continental shelf region off the west coast of North America is seasonally exposed to water with a low aragonite saturation state by coastal upwelling of CO2-rich waters. To date, the spatial [...]

Acidification has sparked discussion about whether regulatory agencies should place coastal waters on the Clean Water Act 303(d) impaired water bodies list. Here we describe scientific challenges [...]

Exponentially rising CO2 (currently ~400 µatm) is driving climate change and causing acidification of both marine and freshwater environments. CO2 directly affects acid–base and ion regulation, [...]

The NOAA Ocean Acidification Program (OAP) was established in May 2011, by the Federal Ocean Acidification Research and Monitoring (FOARAM) Act. This program aims to coordinate [...]

Educational introduction to the chemistry and biological impacts of ocean acidification

News and educational website on ocean acidification

Educational website about ocean acidification created by the Channel Islands National Marine Sanctuary Education Team.

At an oyster hatchery on the Oregon coast, researchers found that production of oyster larvae and growth of young oysters dropped when the aragonite saturation state decreased in seawater. [...]

Ocean acidification, a product of increasing atmospheric carbon dioxide, may already have affected calcified organisms in the coastal zone, such as bivalves and other shellfish. Understanding [...]
