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. The work 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 a total of 169 locations on Stellwagen Bank during three separate surveys from September 2020 to August 2021. During these surveys 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 including temperature, salinity, density, and fluorescence. 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. The images in this dataset are frame-grabs from GoPro video. Supplemental_Information: The locations of image can be extracted from the EXIF header of the images (described in the process steps). Alternatively, the image locations are available from the 2020-2021_station_data_summary dataset available from the Larger Work citation.

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 the SEABOSS (Blackwood and Parolski, 2001; Valentine and others, 2000). The two images from a station are not from the same geographic location on the video drift, but the coordinates stored in the EXIF header information in each station's images are the same. This is because the source video imagery did not display time. The latitude and longitude of the two images are based on the station location time recorded in the cruise logbook (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 2020-2021_station_data_summary dataset (available from the Larger Work citation) station locations are the same as the image locations at each station. All the field activities took place on the Stellwagen Bank National Marine Sanctuary's research vessel, R/V Auk. Although these data represent three separate field activities, the set-up and acquisition on all the cruises is consistent with the exception of the navigation - which was sometimes acquired at 2-second intervals and sometimes at 5-second intervals. Completeness_Report: The images are frame-grab images from video imagery. Each station that has video data 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. In some images from shallow depths, ambient daylight is the dominant light source and causes the images to have a “greenish” coloration. During cruise 2020-012-FA, station 4973 had no video collected therefore there are no seabed images. The 32 stations with video imagery results in 64 seabed images. Cruise 2021-016-FA has video imagery from all 43 stations yielding a total of 86 seabed images. Cruise 2021-017-FA has video imagery from all 93 stations yielding a total of 186 seabed images. 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 dataset (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) in geographic coordinates (World Geodetic System of 1984 [WGS 84]) with a horizontal accuracy of 10 m. Cruise 2020-012-FA acquired navigation at two-second intervals on September 24 and five-second intervals on September 25. Cruise 2021-016-FA acquired navigation at a two-second interval. Cruise 2021-017-FA acquired navigation at a two-second interval. The navigation antenna was located 5.3 m forward of the SEABOSS deployment location. This offset was not accounted for in the navigation acquisition, so navigation fixes represent the antenna location. The SEABOSS may also drift away from the survey vessel when deployed to the sea floor. Lineage: Process_Step: Process_Description: Seabed video imagery was collected using two battery-operated, high-definition (1920 x 1080 pixels) GoPro digital video cameras and a SeaViewer high-definition (1920 x 720 pixels) digital camera mounted on the SEABOSS. The SeaViewer camera had a live feed to the surface and was used only to observe obstacles, like gill nets and lobster gear, in order to avoid entanglement. In the case of camera failure, the additional cameras provided backup video. All images in this dataset are frame-grabs from the the GoPro videos. As the SEABOSS drifted over the seabed, the cameras imaged the seabed at a rate of 60 frames per second from an altitude of ~1 meter. Lighting was provided by two battery-operated Keldan LED dive lights. Each light 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 imagery. Video imagery includes the launch of the SEABOSS, transit through the water column, and the drift over the seabed. The duration of 168 individual video files ranges from 2 to 13.5 minutes. Video files are archived in .MP4 format and range in size from 0.2 to 3.0 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. Data were collected from 2020 to 2021 with the process date representing the most recent acquisition year.

Two video frame-grab images are provided for each station. One image (staXXXX_1) shows a broad view of the landscape as the SEABOSS drifted over the seabed. The second image (staXXXX_2) shows a close-up of the seabed as the SEABOSS was stationary during the collection of the sediment sample.

The location (latitude and longitude), date, and time for each station was extracted from the CSV file. This information was reformatted using an AWK script so that the following columns of information were available: image name (based on the station number), latitude, longitude, GPS time (in the format HH:MM:SS), and GPS date (in the format YYYYMMDD). This information was written to a new CSV file. This process was repeated for each of the three field activities.
