Ocean acidification

Abstract

With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the potential for seawater to become increasing acidic (i.e., ocean acidification). Scientists are concerned that increasing acidity could result in reduced growth or even death of shell-forming animals (e.g., molluscs and certain planktonic organisms) as well as disruption of marine food webs and reproductive physiology. Congress is beginning to focus attention on better understanding this issue and determining how it might be addressed.
