Underwater digital images, single-beam bathymetry, and global positioning system (GPS) data were collected June 24-25, 2014, within a 1-kilkometer (km) x 1-km area around Crocker Reef in the Florida Keys, USA. A total of 91,206 images of the seafloor and water column were collected along pre-defined transect lines and organized into three sets: track1, track2, and track3. This data release contains a subset of those images (25,485 images), all of which were used for benthic habitat classification, and contain GPS data. The data were collected using the U.S. Geological Survey (USGS) shallow Along-Track Reef-Imaging System (sATRIS), a boat-based, pole-mounted sensor package for mapping shallow-water benthic environments. Two other implementations exist, a towed system called Deep ATRIS and a profiling system called Drift ATRIS. All three ATRIS implementations incorporate a digital still camera and an acoustic depth sounder.

Underwater digital images, single-beam bathymetry, and global positioning system (GPS) data were collected July 13 to July 17, 2011 within Dry Tortugas National Park, Florida, USA. A total of 272,828 images of the seafloor and water column were collected along pre-defined transect lines and organized into 14 sets, track1-track14. This data release contains a subset of those images (43,991 images), all of which were used for benthic habitat classification and contain GPS data.

Underwater digital images, single-beam bathymetry, and global-positioning system (GPS) data were collected September 29-30, 2011 around Dustan Rocks Patch Reef, Thor Patch Reef, West Turtle Shoal Patch Reef, and Rawa Patch Reef in the Florida Keys. A total of 101,734 images were collected, covering 4672 square meteres (m2) of reef habitat. This data release contains a subset of 1,420 images, organized into four sets: Track1, Track2, Track3, and Track4. These images were used for coral bleaching assessments, contain GPS data and also include additional, survey-specific Exchangable Image File format (EXIF) header information. The data were collected using the USGS shallow Along-Track Reef-Imaging System (sATRIS), a boat-based, pole-mounted sensor package for mapping shallow-water benthic environments. Two other implementations exist: A towed system called Deep ATRIS and a profiling system called Drift ATRIS. All three ATRIS implementations incorporate a digital still camera, a video camera, and an acoustic depth sounder. In this study, sATRIS images were collected at a rate of 10 hertz (Hz), the single-beam depth soundings at 10 Hz, and the GPS data at 1 Hz. The survey was conducted using the USGS research vessel (R/V) Halimeda, running at a nominal speed of 2 knots.

Underwater digital images, single-beam bathymetry, and global positioning system (GPS) data were collected June 13-14, 2009 at Pulaski Shoal within Dry Tortugas National Park, Florida, USA. A total of 195,406 images of the seafloor and water column were collected along pre-defined transect lines and organized into 3 sets: track1, track2, and track3. This data release contains a subset of those images (32,135 images), all of which were used for benthic habitat classification, and contain GPS data.

Understanding the processes that govern whether a coral reef is accreting (growing) or dissolving are fundamental to questions of reef health and resiliency. A total of 52 surficial sediment samples were collected within a 1-km x 1-km area around Crocker Reef in the Florida Keys, USA, between 2013 and 2014. Samples 1-35 were collected in July 2013 and samples 36-52 were collected in July 2014. The samples were processed using conventional, published techniques (see process step section) to yield grain size and mineralogical data. The dataset, CRKR2013-2014_SEDIMENT_Images.zip contains photomicrograph images that correspond to each sediment sample. These images also include additional, survey-specific EXchangable Image File format (EXIF) header information.

The distribution of benthic habitats for a 1-kilometer (km) x 1-km area around Crocker Reef in the Florida Keys, USA, is based upon underwater digital images of the seafloor collected on June 24 and 25, 2014 (Zawada and others, 2016). The imagery was collected using the U.S. Geological Survey (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 the shapefile included in this data release, Habitat.shp, represent the four general habitat types found at Crocker Reef: hardbottom, rubble, sand, and seagrass.
