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. Purpose: These data were collected to support a collaborative project between the U.S. Geological Survey, St. Petersburg Costal and Marine Science Center and the Coral Reef Evaluation and Monitoring Project (CREMP) of the Florida Fish and Wildlife Research Institute. The purpose of this study, was to evaluate the effectiveness of the Along-Track Reef Imaging System (ATRIS), an automated image-acquisition technology, for assessing a moderate bleaching event that occurred in the summer of 2011 in the Florida Keys. Data obtained from ATRIS were compared to diver-based bleaching assessments conducted contemporaneously by the Florida Reef Resilience Program (FRRP). More than 100,000 images were collected over 2.7 km of transects spanning four patch reefs in a 3-hour period. Corals were assigned to one of four categories: not bleached, pale, partially bleached, and bleached. This dataset was acquired during USGS field activity number 11CRE05, additional survey and data details are available at http://cmgds.marine.usgs.gov/fan_info.php?fan=11CRE05. Supplemental_Information: ATRIS images are saved in the Joint Photographic Experts Group (JPEG) format using a quality factor of 1000 (highest quality/minimal compression). Since the camera and depth sounder are co-located, sounding data corresponds to the distance of the camera above the seafloor. Because the camera and depth sounder are separated from the GPS antenna (Ashtech Geodetic IV antenna, Part Number 701975-01) by a fixed distance (521.5 cm), water depth can be estimated from these distance measurements. GPS position, collection date and time, and camera distance-above-seafloor are stored in the EXIF header of each image. Note: the cited cross reference primarily discusses Deep ATRIS, however, the same camera and control software are used for sATRIS. More information on ATRIS can be found in Lidz and Zawada 2013, and Zawada 2003.

Manufacturer specifications state a 9° beam angle; a depth reading range of 0.4m to 200m; a depth resolution of 0.01m; a depth precision of 0.25% at full range; and a frequency of 200 kHz. Logical_Consistency_Report: Data cover area specified for this project without known issues. Completeness_Report: Some of the sATRIS images collected during this survey did not have GPS and/or depth sounder data, due to drop-outs or recording errors. Images without GPS data could not be differentially corrected, and no water depths were computed for them, so they were excluded from this data release. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Sub-decimeter in horizontal accuracy. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Typically, sub-decimeter vertical elevation accuracies for these data are based on analysis of survey-line crossings. Vertical accuracies may differ based on the type of terrain and the accuracy of the GPS measurements. Lineage: Process_Step: Process_Description: High-resolution, geo-located images of the seafloor were captured between September 29-30, to characterize the seafloor and ground truth benthic habitat mapping efforts. The sATRIS was deployed from the USGS R/V Halimeda following pre-determined survey tracklines. GPS data were simultaneously collected at a fixed land-based location (24° 43' 2.85569", -81° 05' 2.36802") and on the R/V Halimeda during image and bathymetry acquisition using Ashtech Z-Xtreme GPS receivers. 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 GPS data were differentially corrected using GrafNav Version 8.40.5121, converted to the North American Datum of 1983(CORS96) and the North American Vertical Datum of 1988 (using the GEOID12A model) using in-house software, and have sub-decimeter accuracy. Please note that these data are not suitable for navigational use, nor for determining absolute elevation measurements.
