Hi Coral Listers,
Please visit

<http://ccma.nos.noaa.gov/ecosystems/coralreef/reef_fish.html> to view
data collected and photos taken by NOAA scientists during the recent
bleaching event in the Virgin Islands. Widespread bleaching or the loss
of symbiotic algae was observed in 21 coral species or 53% of corals at
91 randomly selected sites with depths from 9-91 feet in the Buck Island
Reef National Monument (BIRNM), St. Croix, U.S. Virgin Islands during
October 16-27, 2005. Researchers from NCCOS and the South
Florida-Caribbean Network of National Parks (NPS-SFCN) found that some
species were more than 90% bleached (e.g., /D. labrynthiformis,
Agaricia/ spp., /Mycetophyllia/ spp., and /M. annularis/), whereas other
corals had no bleaching (e.g., /A. cervicornis/; /D. cylindricus/,
/Eusmilia/ spp., and /Scolymia/ spp.). Based on satellite data from the
National Environmental Satellite Data and Information Service, water
temperatures in the northeastern Caribbean were warmer than normal
(above 28.5^o ) for about 12 weeks and may have contributed to the
observed bleaching event. Prolonged bleaching can be lethal to corals
and, along with disease and pollution, may have contributed to the loss
of about 10% of the world's coral reefs within the past decade. For
