The distribution of benthic habitats for a 1-kilometer (km) x 1-km area around Crocker Reef in the Florida Keys is based upon underwater digital images of the seafloor collected June 24–25, 2014. The imagery was collected using the U.S. Geological Survey 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 four general habitat types found at Crocker Reef: hardbottom, rubble, sand, and seagrass. The data were collected under Florida Keys National Marine Sanctuary permit FKNMS-2013-097.
