coral reefs and global warming, including the effects of sea-level rise and changes in ocean chemistry

Joanie Kleypas is a marine ecologist/geologist who specializes in the interactions between marine ecosystems and climate. In particular, she looks at the impacts of increased carbon dioxide on coral reefs, such as how ocean acidification—C02-induced changes in seawater chemistry—affects the rates at which reef-building coral and algae secrete their calcium carbonate skeletons. Kleypas is a researcher in NCAR's Climate and Global Dynamics Division and its Integrated Science Program.
