Spectrographic imaging. A bird's-eye view of the health of coral reefs

Nature. 2001 Sep 6;413(6851):36. doi: 10.1038/35092617.


Almost three-quarters of the world's coral reefs are thought to be deteriorating as a consequence of environmental stress. Until now, it has been possible to evaluate reef health only by field survey, which is labour-intensive and time-consuming. Here we map live coral cover from the air by remote imaging, a technique that will enable the state of shallow reefs to be monitored swiftly and over large areas.
