These bodies of water do contain salt. Ocean acidification is a reduction in the pH of the ocean over an extended period of time, caused primarily by an increase of carbon dioxide from the atmosphere. Learn about ocean chemistry, life and landscapes on the seafloor, plate movements, shorelines, and icy regions. Rivers, estuaries, and deltas are key to understanding the chemical structure of seawater, and are home to some of the world's most diverse ecosystems.
