	Description The goal of this research is to use practical applications in remote sensing to describe and monitor biological and physical properties of reefs in the Caribbean, concentrating on aspects that enhance both understanding and prediction of reef biodiversity and degradation. In December 2005 NASA flew the AVIRIS hyperspectal sensor and digital camera system on the Twin Otter low altitude platform over reefs of Puerto Rico and the USVI with NASA led field teams on site in the reefs during overflights. Further, AVIRIS was flown on the ER-2 high altitude platform in 2004 over Puerto Rico and the Florida Keys with our field teams in the water. This 2004 mission provides additional data of the Puerto Rico study site. Airborne hyperspectral imagery and digital camera images and coincident field spectra of coral reef constituents will be integrated to assess reef status in terms of the extent of bleached corals, coral mortality, evidence of recovery, evidence of algal overgrowth, and biodiversity.
