CLIMATE CHANGE IN THE OCEAN: ACIDIFICATION BY ATMOSPHERIC CARBON DIOXIDE
Jeff Short, Auke Bay Laboratory, National Marine Fisheries Service
The surface layer of the world's oceans have been acidified by 30% in the last 60 years due to increased atmospheric carbon dioxide levels. Continued unconstrained CO2 emissions may triple ocean acidity by 2100. Such a fundamental and abrupt geochemical shift has significant impacts on marine life, including possible mass extinctions. Cool temperatures and upwelling make Alaskan coastal waters among the most vulnerable to acidification effects, which already threaten shellfish and corals. Many additional, more subtle effects are likely but difficult to predict. Join us for this teleconference to learn more about the implications of ocean acidification for Alaska.
