An azure reef rings two of the Society Islands in the South Pacific. A new archive can help researchers monitor this and other coral reefs and study how their structures differ in various regions. The library, a collaboration between NASA and the University of South Florida, holds more than 1400 images captured by the Landsat 7 satellite between 1999 and 2003. By clicking on a world map, marine biologists and other researchers can zoom in on a particular reef and download close-up photos. The shots provide baseline data on location and size that are missing for many reefs, making it easier to track changes such as declines that might result from global warming and pollution.
