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 75 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 temperature, conductivity, and depth measurements of the water column. Additional information regarding this field activity is available from https://cmgds.marine.usgs.gov/fan_info.php?fa=2015-062-FA. Purpose: These tracklines record the location of the R/V Auk while collecting continuous video of the sea floor. These tracklines will help geolocate the information displayed in the video to the sea floor. This information will be used in making the seabed geologic map.

Completeness_Report: This represents the video trackline information for every video drift line obtained during this cruise. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30, GPS receiver) at one 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: Video methods and data availability: Seabed video images were collected using a battery-operated, high-definition (1920 x 1080 pixels) GoPro digital video camera mounted on the USGS SEABed Observation and Sampling System (SEABOSS). The SEABOSS system actually had two GoPro cameras attached to it - with the second camera mounted a little higher on the frame which only shows a partial view of the seabed. This second camera was used only to observe obstacles, like gill nets and lobster gear, in order to avoid entanglement. Or, in the case of station 4382, provide a backup system if the primary camera failed. As the SEABOSS drifted over the seabed, the forward-looking camera 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 video 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 video images. Video imagery includes the launch and recovery of the SEABOSS, transit through the water column, and the drift over the seabed. The duration of individual video files ranges from 4 to 12 minutes. Video files are archived in .MP4 format and range in size from 0.9 to 2.6 gigabytes. These video files are not available as 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 position (lat/lon) of the start of the video drift was recorded (from the navigation receiver) in the log book at the time of the deployment of the SEABOSS. Video was recorded during the descent through the water column (1-2 minutes), during the drift over the seabed, and during the ascent to the surface. The position (lat/lon) of the end of the video drift was recorded at the beginning of the ascent through the water column. The corresponding times are also recorded.

The julian day was determined by the original start date in the filename of the navigation file as the GPGGA string does not contain any date information. The awk script also made sure that there were not duplicate records in terms of time - such as two navigation points recorded at 16:38:23. However, the script does not check for duplicate coordinate fixes. The individual navigation files were concatenated into a single file - in order of acquisition. This process step and the remaining process steps were performed by the same person - VeeAnn A. Cross.

This was necessary because no time was recorded on the GoPro video, just the time the video file was created. Ideally, there is a match of the same time (with a corresponding navigation fix) in the GPS file to the start video time recorded in the log book. Same thing with the ending time. However, if this situation does not exist, then the closest (in time) navigation record to the start and end time of the video transect is used - along with all the navigation points in between those two times. The python script also combines the extracted points for each video drift line and combines these points into a polyline within a shapefile. The resulting shapefile has a polyline for every video drift comprised of all the navigation points available corresponding to the start and end time of each drift line. Based on the navigation system, the projection of the dataset was set to geographic, WGS 84.
