Benthic Habitats of Buck Island Reef National Monument, St. Croix U.S. Virgin Islands, 2004-02-18 to 2011-08-30 (NCEI Accession 0285904)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 04:32 AM | Dataset Last Updated: December 21, 2023 at 12:00 AM
This data package contains information about the geology and biology of the seafloor from approximately 0 to 1,830 meters in Buck Island Reef National Monument (BIRNM) St. Croix, U.S. Virgin Islands (USVI). It was created by delineating habitats visible in aerial photographs, lidar and multibeam echosounder imagery using ENVI's Feature Extraction (Fx) Module. The minimum polygon size for these habitat maps ranged from 100 square meters (in shallow <30 m depths) to 1000 square meters (in moderate 30 to 150 m depths) to 5,000 square meters (in deep >150 m depths). Additional habitat polygons were manually digitized if they were excluded during the feature extraction workflow. Polygon boundaries were smoothed in ArcGIS to reduce their pixelated appearance. A Classification and Regression Tree (CART) algorithm was used to classify each habitat polygon using georeferenced underwater video & photos collected using SCUBA divers, drop-cameras and remotely operated vehicles (ROVs). Major and detailed geomorphological structure, percent hardbottom, major and detailed biological cover and live coral cover were identified for each polygon. The moderate and deep maps mark the first time that habitats deeper than approximately 30 meters have been mapped in the Monument. These habitat maps will provide a baseline for future biological monitoring studies in BIRNM.
