The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited 33 locations on Stellwagen Bank at which a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties. Purpose: To provide images of the sea floor acquired with the SEABed Observation and Sampling System (SEABOSS). These data provide ground-truth information for geophysical datasets and are used in seabed interpretations. Supplemental_Information: The locations for each image can be extracted from the EXIF header of the images (described in the process steps). Alternatively, the image locations are available from the 2014-070-FA_station_data_summary file available from the Larger Work citation. Additional information regarding the field activity can be obtained from https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-070-FA.

Online_Linkage: https://doi.org/10.5066/P9FWFLPD Online_Linkage: https://www.sciencebase.gov/catalog/item/5d95153ee4b0c4f70d10a4f7 Data_Quality_Information: Logical_Consistency_Report: The image names are in the format staXXXX_Y.jpg where XXXX is the station number and Y is the image number at that station. Each station has two images - one showing a broader view of the landscape (Y=1) and the second a close-up of the seabed (Y=2). The difference in view is related to the closeness of the SEABOSS to the seafloor. See the cross-references for a description of SEABOSS. The two images from a station are not from the same geographic location on the video drift, but the EXIF header information in each is the same. This is because the video source imagery did not display time. The latitude and longitude of the two images is based on the station location time recorded in the cruise log book (the location of a sediment sample, or if no sample was collected, the video drift end location). The latitude and longitude of stations recorded in the log book were later adjusted to match the latitude and longitude recorded at that time in the GPS navigation file. The 2014-070-FA_station_data_summary (available from the Larger Work citation) station locations are the same as the image locations at each station. Completeness_Report: Each station has two images - one showing a broader view of the landscape and the second a close-up of the seabed that was recorded when sampling was attempted. With 33 stations, this makes a total of 66 JPEG images. In some images from shallow depths, ambient daylight is the dominant light source and causes the images to have a “greenish” coloration. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Although the images do not represent spatial data, the spatial information is available in the EXIF header of each image, which is derived from the station location in the station data summary file (available from the Larger Work citation). The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30, GPS receiver) at two second intervals with a horizontal accuracy of 10 m. The navigation antenna is located 5.3 m forward of the SEABOSS deployment location. This offset was not accounted for in the navigation acquisition (navigation fixes represent antenna location). Lineage: Process_Step: Process_Description: Seabed video imagery was collected using one battery-operated, high-definition (1920 x 1080 pixels) GoPro digital video camera mounted on the USGS SEABed Observation and Sampling System (SEABOSS). As the SEABOSS drifted over the seabed, the GoPro camera imaged the seabed at a rate of 60 frames per second from an altitude of ~1 meter. Lighting was provided by one battery-operated Keldan LED video light that provided a light flux of up to 9000 lumens at a correlated color temperature of 5000 kelvins. Two parallel red lasers mounted 20 centimeters apart provided a scale in the video images. Video imagery includes the launch of the SEABOSS, transit through the water column, and the drift over the seabed. The duration of individual video files ranges from 2.5 to 4.5 minutes. Video files are archived in .MP4 format and range in size from 0.6 to 1.1 gigabytes. These video files are not part of this data release. Video files are archived at the USGS Woods Hole Coastal and Marine Science Center, 384 Woods Hole Road, Woods Hole, MA 02543.

The location (latitude and longitude), date, and time for each station was extracted from the CSV file.

Although the two images from each station are not from the exact same place, the same information for that station was populated in each photo. The Python script uses ExifTool (version 11.54) to write the information to the image headers of the full-resolution images. The following tags were populated in the JPEG image headers.
