Data_Sheet_1_Impacts of pH on the Fitness and Immune System of Pacific White Shrimp.docx
The atmospheric partial pressure of CO 2 (pCO 2 ) has been increasing dramatically since the beginning of the industrial revolution and about 30% of the CO 2 produced by anthropogenic activities was absorbed by the ocean. This led to a perturbation of the seawater carbonate chemistry resulting in a...

The atmospheric partial pressure of CO 2 (pCO 2 ) has been increasing dramatically since the beginning of the industrial revolution and about 30% of the CO 2 produced by anthropogenic activities was absorbed by the ocean. This led to a perturbation of the seawater carbonate chemistry resulting in a decrease of the average surface ocean pH by 0.1 and termed ocean acidification (OA). Projections suggest that pCO 2 may reach 900 μatm by the end of the twenty-first century lowering the average pH of the surface ocean by 0.4 units. The negative impacts of OA on many species of marine invertebrates such as mollusks, echinoderms, and crustaceans are well documented. However, less attention has been paid to the impacts of low pH on fitness and immune system in crustaceans.
