Abstract:

The presence and absence of the four substrate and four biological cover types were documented at 1,353 locations on the insular shelf south of St. Thomas and St. John. At each location, an underwater camera system was used to collect high definition (HD) video at 30 frames per second at 1080x1920 resolution. This GIS dataset depicts the location of these underwater videos, as well as the name, location, time collected, and the presence and absence of the substrate and cover types. A portion of these underwater videos (n=1,005) were used to develop the habitat predictions and the composite habitat map. A separate subset of these underwater videos (n=348) were used to assess the performance of the habitat predictions and accuracy of the composite habitat map.

Purpose:

The insular shelf south of St. Thomas and St. John, in the U.S. Virgin Islands (USVI) is an expansive geomorphologic feature with extensive mesophotic coral reefs occurring at 30 to 150 meter depths. These mesophotic reefs are part of a broader coral reef community in the U.S. Caribbean that provide a wide range of ecosystem goods and services estimated to provide $187 million per year (in 2007 US dollars) to local communities. While these reefs provide great economic value to local communities, they are increasingly under threat from multiple human-caused stressors, making it critical for the USVI and Puerto Rico jurisdictions to find ways to preserve and sustainably manage them. Ideally, the first step in any marine management process is to comprehensively map and inventory the location of coral reef resources. The geographic information system (GIS) layers and products provided in this report represent the first complete habitat map for the insular shelf south of St. Thomas and St. John. These products also represent the culmination of an extensive seafloor mapping campaign conducted by NOAA’s National Centers for Coastal Ocean Science (NCCOS) in collaboration with regional partners.

Process Steps

Process Step 1

CC ID: 696808
Description:

The process for collecting both the GV and AA data was identical at each site in the field. Sites were accessed via small boat using a hand-held Garmin 76 global positioning system (GPS) unit. Once the drop camera was deployed, boat location and drift was recorded every five seconds for the duration of the underwater video using a Trimble GeoXH GPS receiver. As the video camera was deployed to the bottom, the presence and absence of the five substrate and four cover types were recorded at each site in real time on the Trimble GeoXH. Once back in the office, GPS data were post-processed and differentially corrected using the closest Continually Operating Reference System (CORS) station, which were on St. Thomas (station STVI), Culebra Island, Puerto Rico (station CUPR) and St. Croix (station CR01). All underwater videos were reviewed a second time by benthic experts and the presence (1) and absence (0) of each substrate and cover type were confirmed in the office. Multiple substrate and cover types were often present at each site. For a complete description of the processing and analysis methods see Costa et al. 2017.
