2012) due to the combined effects of atmospheric CO 2 dissolution and upwelling that brings nutrient-enriched, low pH waters onshore. Declines in Oregon coast shellfish hatchery production over the last several years have been correlated with such upwelling events In waters of Puget Sound, Washington, Feely et al. (2010) found pH as low as 7.5, owing to the combined effects of global CO 2 dissolution, upwelling of aged, low pH waters, and local respiration.
