Joanie Kleypas is a marine scientist at the National Center for Atmospheric Research, who investigates how rising atmospheric carbon dioxide is affecting marine ecosystems, including both climate change and ocean acidification. Kleypas conducted her doctorate research on the Great Barrier Reef of Australia in the 1990s. Kleypas is driven to find solutions to the worsening coral reef crisis. She uses high-resolution oceanographic modeling to help identify coral reef refugia from the expected impacts of climate change on adult corals and the transport of their larvae to other reefs. Kleypas also leads a coral reef restoration project in Costa Rica.
