Report on the ocean acidification crisis in Massachusetts

Since the industrial revolution, the world’s oceans have become increasingly acidic. The main drivers of ocean acidification in Massachusetts are (1) global increases in atmospheric carbon dioxide resulting from anthropogenic emissions, and (2) local nutrient pollution leading to the eutrophication of coastal waters.

Many marine species that evolved under less acidic conditions are threatened by ocean acidification, including some that are critical to the Massachusetts economy. Species that are both economically important and vulnerable to acidification include mollusks such as the sea scallop and eastern oyster.

Massachusetts will be disproportionately affected by ocean acidification due to the relative importance of its coastal economies and environments.
