We dove 30 to 90 ft, 5 sites, Dry Tortugas National Park and on the Tortugas Banks, 8, 9 Sept. The incidence of bleaching (complete loss of color, total colony or partial) was moderate at most sites. Approximately 15 to 25 percent of the colonies were affected. Water temperature (diving computer data) was 86 to 87 F. Most Colpophyllia natans were exhibiting lightened color, but few were displaying bleached condition. On the Tortugas Banks (70 to 90 ft), the bleaching was less intense. We walked along the moat wall of Ft. Jefferson and saw many corals were very bleached. water depth is approximately 10 ft. Palythoa, Millepora, and Scleractinia all exhibited intense bleaching.
