Coral Reef Health Survey

Coral reef health may be estimated efficiently from sensors on airplanes and satellites in the future, according to a NASA scientist who will discuss her work Dec. 9, 2003, during the American Geophysical Union's fall meeting in San Francisco.

Publication Size	Researchers using handheld 'spectroradiometer' measure reflected light readings from Acropora palmata, or elkhorn coral to determine the reef health in the Bahamas. The collected data is compared to the reading taken during aerial surveys. Image Numbers: ACD03-0233-015 ACD03-0233-014 ACD03-0233-003

Publication Size	Acropora palmata, or elkhorn coral exhibiting white band disease. Acropora palmata is a major reef-building coral prevalent in the Bahamas, but is suffering from 'white band disease.' Elkhorn coral has severely declined in many areas of the Caribbean and may be on the verge of becoming an endangered species.
