Shallow ATRIS (sATRIS) Images-Dry Tortugas National Park, Florida, 2011

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, FL, 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, track2, track3, track4, track5, track6, track7, track8, track9, track10, track11, track12, track13, and 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. 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.
