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: These video tracklines indicate where imagery data of the sea floor were collected. 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. All stations collected video. 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 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 videos were 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). See the cross-references for additional description of the SEABOSS system. 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 and recovery 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 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 (latitude and longitude) and time of the start of the video drift was recorded from the navigation receiver by hand in the log book at the time of the deployment of the SEABOSS, when it reached the seabed, and when it left the seabed. Latitude and longitude positions recorded by hand in the log book were later adjusted to match the data recorded in the GPS navigation file based on time. Video was recorded during the descent through the water column (1-2 minutes) and during the drift over the seabed.

The Julian day was determined by the original date in the filename of the navigation file as the GPGGA string does not contain any date information. The script made sure to round the latitude and longitude values to five decimal places in the same way that Excel would round the values. The AWK script also made sure that there were no duplicate records in terms of time, such as two navigation points recorded at 16:38:23. Depending on the boat drift rate, navigation fixes carried out to only five decimal places could have duplicate 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.

Ideally, there is a match of the same time (with a corresponding navigation fix) in the GPS file to the start and end video times recorded in the log book. 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. These extracted points were then combined into a polyline shapefile. The resulting shapefile has a polyline for every video drift. Based on the navigation system, the coordinate system of the dataset was set to geographic coordinates, WGS 84.
