Ocean Acidification

Sist oppdatert: May 20, 2019

Ocean acidification (OA) refers to a reduction of pH in the ocean over an extended period of time. It is primarily caused by the oceanic uptake of extra atmospheric carbon dioxide (CO2), but other human activities also contribute. OA changes the chemistry of the seawater and is thought to have a range of possibly harmful consequences. We investigate the present and future rates of OA using advanced observational techniques and global and regional models.
