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 61 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: The record of data acquired at each station provides water depths, times, and coordinates of video imagery and samples to aid in the interpretation and mapping of seabed substrate types. This data summary file indicates what data are available for the interpretation at each station. Supplemental_Information: Additional information regarding the field activity can be obtained from https://cmgds.marine.usgs.gov/fan_info.php?fan=2015-017-FA . The grain-size analyses of the sediment samples collected during this field activity is available in a separate publication (Valentine and Cross, 2019; link available from the cross-reference citation).

The locations (latitude and longitude values) are based on information recorded in the cruise log book and later adjusted to match the data recorded in the GPS navigation file. For this field activity, all but one station has the station location and sample acquisition at the start of the video drift. The one station with the station location and sample acquisition at the end of the video drift is station 4308. Completeness_Report: These station locations and data collection information represent all the information pertinent to the 2015-017-FA field activity. 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) with a horizontal accuracy of 10 m. Navigation data were recorded at two-second intervals on May 29 and June 3, 2015. Navigation data were recorded at 11-second intervals or better on May 18-19, 2015 due to a problem with the GPS receiver. 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). The SEABOSS may also drift away from the survey vessel when deployed to the sea floor. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Water depth was determined using a Simrad ES60, 120 kHz, single beam echosounder using a dual frequency 120-25 kHz transducer, which detects the seabed to a depth of 800 m. Depth values were rounded to the nearest meter to account for ship motion. Lineage: Process_Step: Process_Description: Sediment sampling methods: > As a part of the process of mapping the sea floor, the USGS developed the SEABed Observation and Sampling System (SEABOSS) to collect samples and video and photographic images of the seabed to aid in the interpretation of seabed sonar imagery. A modified Van Veen sediment grab sampler is mounted in the center of the SEABOSS frame, which ensures the sampler is properly oriented on the seabed when a sample is collected. Before deployment, the sampler bucket jaws are opened by collapsing the extended arms to a near-horizontal position and locking them in place with two catches. The sampler operates passively to sample the seabed; it is not spring loaded. To collect a sediment sample, the SEABOSS frame was lowered gently onto the seabed, reducing tension on the cable, which caused the two locking catches to be automatically released by gravity. As the cable was retrieved, the grab sampler arms were pulled upward, closing the bucket around the sediment, and the SEABOSS was lifted off the seabed. > The SEABOSS was retrieved and set upon a wooden platform that kept the sampler bucket and camera systems above the deck. The sampler arms were held in the upright position manually or by tension on the cable, the two doors on the upper side of the bucket were opened, and the sediment was removed. For this project, the upper 2 cm of sediment, representing the surface of the seabed, were removed with a rectangular shovel 2-cm deep and stored in a plastic bag for grain-size analysis. The remaining sediment was dumped into a tray on the deck below the sampler and discarded, after which the sampler was washed in preparation for sampling at the next site. Further information on the SEABOSS can be found in Blackwood and Parolski (2001) and Valentine and others (2000). > Grain-size analyses of the sediment samples were performed at the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center in Woods Hole, Massachusetts, by using a standard suite of analytical methods (Poppe and others, 2014). This laboratory has been in operation since 1963 and has analyzed many thousands of sediment samples collected by the USGS in New England. > Video methods and data availability > Seabed videos were collected using two battery-operated, high-definition (1920 x 1080 pixels) GoPro digital video cameras mounted on the SEABOSS. The SEABOSS system also had a Subsea Video Systems digital camera attached to it with a live feed to the surface. It was mounted a little higher on the frame and was used to observe obstacles, like gill nets and lobster gear, in order to avoid entanglement. In case of camera failure, the second GoPro camera provided backup video. As the SEABOSS drifted over the seabed, the GoPro cameras 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 60 individual video files ranges from 3.5 to 14.2 minutes. Video files are archived in .MP4 format and range in size from 0.8 to 3.1 gigabytes. The video files are not part of this data release, but they are archived at the USGS Woods Hole Coastal and Marine Science Center. > The position (latitude and longitude) and time were 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, when a grab sample was attempted, 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. 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. > Video frame grabs were captured to show typical images of the seabed. These images are available from the Larger Work citation. > The station position (latitude and longitude) represents the location of the sediment sample (if collected). For this field activity, the sample acquisition occurred at the start of the video drift except for station 4308, which occurs at the end of the video drift. If a sediment sample was not collected, the station position represents the end of the video drift. > Water depth was determined using a Simrad ES60, 120 kHz, single beam echosounder using a dual frequency 120-25 kHz transducer, which detects the seabed to a depth of 800 m. Depth values were recorded in a log book at the time of deployment of the SEABOSS and were rounded to the nearest meter to account for ship motion.
