That's the tally of NASA's Landsat 7 satellite as it continues to deliver cutting edge images and information about the Earth.    With the Landsat 7 data we can rigorously test hypotheses about how entire reef ecosystems form,-- says coral reef ecologist Bruce Hatcher of Dalhousie University--We no longer are limited to the observations we can collect by wandering around in small boats and sampling individual reefs to infer large-scale processes from a few samples.

The surface area of live coral in this reef has declined from more than 50 percent to less than 5 percent since 1975.
