Abstract:
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. 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.
Purpose:
These data were collected to support the Benthic Habitat Mapping & Monitoring task of the USGS Coral Reef Ecosystem Studies project (http://coastal.er.usgs.gov/crest/). Benthic community composition, topographic relief, areal extent, and temporal stability are critical factors that contribute to the value of a given marine habitat. With the emergence of Marine Protected Areas (MPAs) as a priority management tool for protecting coral reef resources, knowledge of these essential habitat components is paramount for designing effective strategies for the management of marine reserves. This dataset was acquired during USGS field activity number 09DAF01, additional survey and data details are available at https://cmgds.marine.usgs.gov/fan_info.php?fan=09DAF01.
Supplemental_Information:
sATRIS images were 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 Marine antenna, Model 111661, S/N 6655) by a fixed distance (408.94 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 Exchangable Image File format (Exif) header of most images. More information on ATRIS can be found in Lidz and Zawada, 2013.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All soundings were collected with an Airmar EchoRange SS510 Smart Sonar Depth Sensor. Manufacturer specifications state a 9-degree beam angle; a Depth Reading Range of 0.4 m to 200 m; a Depth Resolution of 0.01 m; a Depth Precision of 0.25% at full range; and a Frequency of 200 kHz.
Logical_Consistency_Report:
Data cover the area specified for this project without any 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. Images without depth sounder data are included in this data release, but the depth and camera height information is missing from those images.
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.

Process_Step:
Process_Description:
High-resolution, geo-located images of the seafloor were captured between June 13 and 14, 2009, to characterize the seafloor and ground truth benthic habitat mapping efforts. The sATRIS was deployed from the USGS research vessel (R/V) Halimeda, running at a nominal speed of 2 knots and following pre-determined survey tracklines. GPS data were simultaneously collected at a fixed land-based location (24 37 46.70015 N, 82 52 22.29828 W) 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 5 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 (2011) and the North American Vertical Datum of 1988 (using the GEOID12A model), and have sub-decimeter accuracy. Please note that these data are not suitable for navigational use, nor for determining absolute elevation measurements.

Process_Description:
Water depths were computed for each sATRIS image with valid, differentially-corrected GPS and depth-sounder data using USGS-developed software. Not all images have valid GPS and/or sounder data. These images could not be differentially-corrected, and no water depths were computed for them, so they were excluded from this data release. All the data collected during this survey are stored on hard drives and archived at the U.S. Geological Survey office in St. Petersburg, Florida.

Overview_Description:
Entity_and_Attribute_Overview:
All Exif headers contain: Caption, Artist, Credit, Copyright, CopyrightNotice, Comment, Keywords, Contact, Caption-Abstract, GPSLatitude, GPSLatitudeRef, GPSLongitude, GPSLongitudeRef, water depth (labeled as GPSAltitude), GPSAltitudeRef, camera distance to seafloor (labeled as SubjectDistance), GPSTimeStamp, GPSDateStamp. Information is duplicated in some tags, this was done because different software packages access different tags.
Entity_and_Attribute_Detail_Citation:
To extract the information from the image headers using ExifTool, the following command can be used (tested with ExifTool version 10.2.5.0): Exiftool -csv -f -filename -GPSTimeStamp -GPSDateStamp -GPSLongitude -GPSLatitude -GPSAltitude -GPSAltitudeRef -n -SubjectDistance -Artist -Credit -Comment -Keywords -Caption -Caption-Abstract -Copyright -CopyrightNotice -Contact -ImageDescription directoryname/*.jpg > out.csv. The -csv flag writes the information out in a comma-delimited format. The -n option formats the latitude and longitude as signed decimal degrees.
