Not meant to be a comprehensive account of all corals. Definitions: Intensity of bleaching (whiteness): low, moderate, heavy, mortality Cover of bleaching: X% Offshore Buttress Zone: Depth: 35' Temp: 26C (this seems low to me but that's what YSI meter read at 35', 30C at surface) Overall bleaching: moderate, 60-80% bleaching cover M. annularis: moderate to heavy, 50-80% cover C. natans: moderate, 40-60% cover Sid. sid: light A. cervicornis: mod-heavy, 60-80% Reef crest: Millepora: heavy, 100% cover A. palmata: heavy, 80% Back Reef: A. palmata: heavy, some mortality with algal overgrowth, 90% cover Offshore patch reef (behind back reef): Temp: 31C Depth: 20-30' Sid. sid: heavy, 80-100% cover (note difference between here and offshore) E. fastigiata: moderate Mid Channel Patch Reef (in Hawk's Channel- our equivalent to a lagoon except deeper and chronically turbid- contains many luxuriant patch reefs with immense soft corals (2 m high)): Depth: 10' Temp: 31C M. cavernosa: moderate, 60-80% cover M. ann.: moderate, 60-80% cover
