NASA's Jet Propulsion Laboratory and reef scientists from around the world are announcing the launch of a campaign Thursday, June 9, to gather new data on coral reefs like never before. Using specially designed instruments mounted on high-flying aircraft, the scientists are embarking on a mission to map large swaths of coral around the world in hopes of better understanding how environmental changes are impacting these delicate and important ecosystems. The CORAL team will study the reefs of Hawaii, Palau, the Mariana Islands, and Australia's Great Barrier Reef over the next three years. (AP Photo/Caleb Jones), APTOPIX
