Welcome to the NOAA Ocean Acidification Program! Ocean acidification is emerging as an urgent environmental and economic issue on our nation’s east and west coasts and in many areas of the world.
Ocean acidification is occurring because the world’s oceans are absorbing increasing amounts of atmospheric carbon dioxide, leading to lower pH and greater acidity. This is literally causing a sea change and threatening the fundamental chemical balance of ocean and coastal waters from pole to pole.
