About BIOACID: Since 2009, more than 250 BIOACID scientists from 20 German research institutes have investigated how different marine organisms respond to ocean acidification and increasing carbon dioxide concentrations in seawater, how their performance is affected during their various life stages, how these reactions impact marine food webs and elemental cycles and whether they can be mitigated by evolutionary adaptation.
