The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Coral ecosystem connectivity from Pulley Ridge to the Florida Keys: habitat and benthic macrobiota from underwater still images from 2012-08-17 to 2015-09-02 (NCEI Accession 0210993) |
| Abstract: | This dataset comprises still images recorded by remotely operated vehicle (ROV) surveys during four cruises from 2012 to 2015, which characterized the mesophotic coral ecosystems at Pulley Ridge and Dry Tortugas. A total of 87 ROV dives surveyed 91 random blocks in the Pulley Ridge and Dry Tortugas regions, and covered a distance of 150 kilometers at depths from 22.9 to 114.4 meters. The dataset totals 14,942 in situ digital still images, of which 11,104 were analyzed using Coral Point Count with Excel Extensions (CPCe) for benthic habitat, benthic macrobiota, and coral/sponge/algal cover. |

| Supplementary information: | METHODS: Each ROV dive was approximately 1 km in length, lasting approximately 3–4 hours, which documented 1 km x 1 km randomly selected blocks with continuously recording digital video and digital still images. Survey blocks were selected using a statistically rigorous sampling protocol. In ArcGIS, a fishnet grid of 1 km x 1 km blocks was overlaid on the available bathymetry maps for Pulley Ridge and Dry Tortugas from which 91 random blocks were selected for the surveys over the four-year period. To characterize benthic habitat and macrobiota, five random 100-m video/photo transects were conducted within each block. Generally, the ROV was kept Submission Package ID: TPY1TH |
