bb1
Diploria strigosa Symmetrical Brain Coral. The first documented chronological obsevations of a coral colony succumbing to Black Band disease.
subject 1
Siderastrea siderea/ Massive Starlet Coral. These coral colonies are typically uniform in color and polyp shape. S.siderea often shown signs of stress by exhibiting a splotchy coloration that can be present for months at a time. They succumb to Black Band and Brown Spot disease and were the first specie to show signs of coral bleaching prior to the 1997 coral bleaching event. Often they are observed spewing mucus from the polyps. Years ago this colony suffered physical damage from the shank of a large anchor indicated by the flat surface on it's north face. In the past this area of the reef was used as an emergency shelter from northerly winds by commercial fishing vessels. The bottom of this reef is strewn with old pieces of shrimp boat gear.
subject 2
Diploria strigosa/ Symmetrical Brain Coral. This colony is located adjacent to subject 1 and exibited areas of recently lost coral tissue from the beginning of the survey in 1993 . Brain corals erode very quickly after they lose their living tissue.
subject 3
Montastrea faveolata/ Mountainous Star Coral. This is the oldest coral colony near buoy number 10, approximately 500 years old. This majestic coral colony exhibited very good health until the 1997 coral bleaching event. Mountainous star corals sucumb to many diseases especially Yellow Band Disease.
subject 4
Subject 4 is actually a coral outcropping with no live coral coverage that has several sponges attached to it. At it's base was a cluster of Acropora cervicornis/staghorn coral. This subject is used as a bearing point for the buoy 10 transect. It is located south of subject 3.
subject 5
This small Montasrea cavernosa is growing on the east face of subject 3 and was surrounded by a large sea whip and had a thick patch of halimeda algae growing below it. A cluster of sponges can also bee seen adjacent to it. This colony and the life surrounding it are interesting to follow through time.
subject 6
Montasrea franksi Boulder Star Coral. This coral grows with irregularly shapped mounds and has yellow blotches scattered about it's surface. This colony is very hardy and has survived where neighboring corals of different species have died.
subject sf1
Gorgonia ventalina/ Common Sea fan This sea fan was growing adjacent to subject 2 and appeared in good health in 1993. Sea fans are subject to the fungal infection Aspergillosis, a land based fungus that enters the marine environment via storm water run off and by atmospheric deposition. Thousands of sea fans have been lost to this infection near Key West.
subject sf2
Subject sf2 Gorgonia ventalina Common Sea Fan. It is located on the east face of YB1 and will dissappear over time.
subject YB1
Montastrea faveolata Mountainous star coral This is the first coral colony discoverd to have Yellow band disease see catagory YB1 chronology. This coral is located several hundred feet south of subject 3. Core samples were removed from the diseased area for analysis in an attempt to discover the cause of the disease.
subject YB2
Montastrea faveolata Mountainous Star Coral Subject YB2 is located 50 feet due south of subject YB1.
subject YB3
Montastrea faveolata Mountainous Star Coral. This subject is located about 50 feet south of YB2. It will go through some very strange transitions after the 1997 coral bleaching event.
