THE TOXICOLOGICAL INTERACTION BETWEEN OCEAN ACIDITY AND METALS IN COASTAL MEIOBENTHIC COPEPODS
International audience Increased atmospheric CO 2 concentrations are causing greater dissolution of CO 2 into seawater, and are ultimately responsible for today's ongoing ocean acidification. We manipulated seawater acidity by addition of HCl and by increasing CO 2 concentration and observed th...
