The distribution of benthic habitats for a 1-km x 1-km area around Crocker Reef in the Florida Key is based upon underwater digital images of the seafloor collected June 24-25, 2014. The imagery was collected using the USGS shallow Along-Track Reef-Imaging System (sATRIS), a boat-based, pole-mounted sensor package for mapping shallow-water benthic environments. The polygons contained in this shapefile represent the 4 general habitat types found at Crocker Reef: hardbottom, rubble, sand, and seagrass.
