| Purpose | Determine the geographic extent of elkhorn coral populations in the past. Sample subfossil elkhorn corals for radiometric dating. | ||||||||
| Location | Dry Tortugas National Park | ||||||||
| Summary | Performed diver surveys to locate sub-fossil A. palmata reefs. GPS locations of identified sites were noted and 10 coral rock samples were taken using a hammer and chisel. | ||||||||
| Info derived | Hand samples from sub-fossil Acropora palmata (elkhorn coral), GPS coordinates of locations with subfossil A. palmata. | ||||||||
