Landsat 7 measurements of live coral in the Carysfort Reef, the largest reef in the Florida Keys, matches detailed surveys taken on the ground, according to a joint study by Frank Muller-Karger, Serge Andrefouet, and Dave Palandro of the University of South Floridas College of Marine Science and Phil Dustan of the College of Charleston. The surface area of live coral in this reef has declined from more than 50 percent to less than 5 percent since1975. -

The structure and extent of coral reefs can now, for the first time, be
monitored globally, thanks to new observations from NASAs Landsat 7
spacecraft. Detailed images of reefs from nearly 900 locations around the
world have been collected in the first year of the Landsat 7 mission.

Located in tropical latitudes, the hard structures we
know as coral are really the incremental build-ups of calcium
carbonate deposited from the skeletal remains of these tiny
colonial animals.
