Approximately 130 linear kilometers of subbottom (seismic-reflection) and 234-kilohertz interferometric sonar (bathymetric and backscatter) data were collected along with sediment samples, sea floor photographs, and (or) video at 26 sites within the geophysical survey area. Sediment grab samples were collected at 19 of the 26 sampling sites and video and (or) photographic imagery of the sea floor were taken at all 26 sites. These survey data are used to characterize the sea floor by identifying sediment-texture, seabed morphology, and underlying geologic structure and stratigraphy. Data collected during these 2016 surveys are included in this data release: https://doi.org/10.5066/P9HZHXXV. More information can be found on the websites for the Woods Hole Coastal and Marine Science Center field activities at https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-017-FA and https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-037-FA. Purpose: This dataset is used to display the videos and locations of bottom videos acquired with a SeaViewer 6000 HD Sea-Drop video camera on the Mini SEABed Observation and Sampling System (MiniSEABOSS) aboard the Research Vessel (R/V) Rafael by the U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center during USGS field activity 2016-037-FA (July 15, 2016). Video data serve as a means to visually classify grain size and are especially important for sites where no physical sediment sample was collected. Supplemental_Information: Bottom photographs were also taken at all but one station (see shapefile 2016-037-FA_photos.shp available from the larger work citation). Physical sediment samples, which provide additional information about the seabed, were also collected at most stations and analyzed in the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center (see 2016-037-FA_samples.csv available from the larger work citation). For more information about this field activity, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-037-FA. The sampling data were collected to ground truth (verify) acoustic data collected during USGS field activity 2016-017-FA.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The end time of the video drift used to map the bottom video tracklines (field ENDTIME in the shapefile) was calculated using the video start time and duration. This end time may be off by up to two seconds and was not assessed for accuracy by comparing it with the time burned on to the upper right corner of the video's last frame. Logical_Consistency_Report: All bottom videos were acquired using a SeaViewer 6000 HD Sea-Drop video camera on the MiniSEABOSS. One video (clip 022) was of two stations and was split to create separate videos for each station. Gaps in sequential clip numbers exist because videos taken in the water column were not processed. The tracklines may self-intersect or self-overlap; at times the ship was moving so slowly that the resolution of the Differential Global Positioning System (DGPS) makes a trackline appear to double back on itself. Completeness_Report: This dataset includes bottom video in MP4 format and a trackline shapefile of the location of the ship for the duration of the video during USGS survey 2016-037-FA. Twenty-six stations were occupied within the study area, and bottom video was acquired at all 26 stations. Three acquired videos are not included in this publication: two videos of the water column (clip 027 and clip 028) and one video used for camera calibration (clip 031). One video (clip 022) was of two stations; it was split to create separate videos for each station and clipped to the duration that the camera was within view of the sea floor. A total of 26 videos and 26 video tracklines are included in this dataset. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Sources of horizontal inaccuracy may be due to the video end time used to create the shapefile or the navigation data. The end time of the video drift used to map the bottom video tracklines (field ENDTIME in the shapefile) was calculated using the video start time and duration, rather than using the time burned on to the upper right corner of the video's last frame. The calculated end time may be off by up to two seconds and accounts for +/- 1 meter of horizontal uncertainty. Navigation for survey 2016-037-FA used DGPS. The DGPS was set to receive fixes at a one-second interval in geographic coordinates (World Geodetic System of 1984 [WGS 84]). The recorded position of each point along the video trackline is the position of the DGPS antenna on the survey vessel, located on the aft of the R/V Rafael's cabin just port of the centerline, not the location of the MiniSEABOSS sampler. The MiniSEABOSS was deployed approximately 2 meters to the starboard side of the DGPS antenna. No layback or offset was applied to the recorded position. In addition to the +/- 2-meter offset, the sampler may drift away from the survey vessel when deployed to the sea floor. Based on the various sources of horizontal offsets, a conservative estimate of the horizontal accuracy of the video trackline locations is 2-4 meters. At times the ship was moving so slowly that the resolution of the DGPS makes a trackline appear to double back on itself.

The observations from video and still cameras and the sediment data are used to explore the nature of the sea floor and, in conjunction with high-resolution geophysical data, to make interpretive maps of sedimentary environments and validate acoustic remote sensing data. This setup of the MiniSEABOSS incorporates a downward-looking SeaViewer 6000 HD Sea-Drop video camera with topside feed, two GoPro HERO4 Black digital cameras, a modified Van Veen sediment sampler, and a dive light. A compass and depth sensor were attached to the sampler as well and are sometimes visible in the top-mounted GoPro to be used for troubleshooting as necessary. The elements of this particular MiniSEABOSS system are held within a stainless-steel frame that measures ~1 x 1 meters. The frame has a stabilizer fin that orients the system as it drifts over the seabed. A dive light was mounted at the top of the frame and aimed downward to illuminate the seabed for photographs. One of the GoPro HERO4 Black cameras was mounted lower, approximately 40 centimeters from the bottom, on the MiniSEABOSS frame and captured bottom photos every 5 seconds and backup video, while the other was mounted higher, approximately 70 centimeters from the bottom of the frame, and recorded additional backup bottom video. Two red lasers were set 20 centimeters apart (both as they are mounted on the MiniSEABOSS frame and as seen in photographs and video on the seabed) for scale measurements. The red laser dots can usually be seen in the imagery depending on the bottom type and distance to the sea floor. A third laser is positioned at an angle so that when it intersects the other lasers, the MiniSEABOSS is at the optimum height (approximately 75 centimeters) off the bottom for a still photograph. The R/V Rafael occupied one of the target stations and the MiniSEABOSS was deployed off the vessel's starboard side. The winch operator lowered the sampler until the sea floor was observed in the top-side live video feed. The vessel and sampler drifted with wind and current for up to a few minutes to ensure a decent image with a clear view of the sea floor and then at most stations the winch operator lowered the Van Veen sampler until it rested on the sea floor. When the system was raised, the Van Veen sampler closed and collected a sample as it was lifted off the sea floor. The sampler was recovered to the deck of the survey vessel where a subsample was taken for analysis at the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center. Sediment samples were only attempted in areas where collecting a sample would not damage the MiniSEABOSS; therefore, no samples were collected in areas with a cobble, boulder, or rocky seabed, as identified in real time using the top-side live video feed. Bottom video was recorded from the downward-looking SeaViewer 6000 HD Sea-Drop video camera directly on to solid-state drive (SSD) media using an Odyssey7 video recorder. DGPS navigation from a Hemisphere DGPS receiver was logged through HYPACK navigation software and a DataBridge data logger. The DGPS was set to receive fixes at a one-second interval in geographic coordinates (WGS 84). A log file for the survey was saved in ASCII text format. Process_Step: Process_Description: Twenty-six stations were occupied aboard the R/V Rafael during USGS survey 2016-037-FA with the MiniSEABOSS (Blackwood and Parolski, 2001). The MiniSEABOSS was equipped with a Van Veen grab sampler, two GoPro HERO4 Black digital cameras, and a downward-looking SeaViewer 6000 HD Sea-Drop video camera. The R/V Rafael occupied one of the target stations, the MiniSEABOSS was deployed, and then the vessel and MiniSEABOSS drifted with wind and current for up to a few minutes to ensure a decent video with a clear view of the sea floor. Bottom video was recorded from the downward-looking SeaViewer video camera directly on to SSD media using an Odyssey7 video recorder.

A log file for the survey was saved in ASCII text format. An AWK script (awkhypack.gpgga_v0_9.awk) was run on the log file to parse for the GPGGA navigation string and create an ASCII Comma Separated Value (CSV) text file. The output file was then reformatted using an AWK script (nav_time_reformat.awk), creating a final processed navigation file for the entire sampling survey.

A shell script (do_concat_and_TCBurn.sda) was run to join the video clips for each station (the Odyssey7 splits clips into less than 4GB segments), burn the date and time in UTC on to the upper right corner of the video, and transcode the video from MOV to MP4 format. The script also created a text file with the date, start time, and duration of each video recording. One video (clip 022) was of two stations, so it was split to create separate video for each station and clipped to the duration that the camera was within view of the sea floor. The videos were renamed to include the field activity identifier, camera, and date and start time in the ISO 8601 standard in the filename.

The script reads the video start time and duration from the text file, calculates the video end time, extracts the navigation points that fall within those start and end times, and exports the navigation fixes to a CSV file. The script had an error for the last video (clip 031) because corresponding navigation data were not available. This video is a calibration video and was not included in this publication.

The Points to Line tool was then run with the video trackline points as the input features and the video filenames as the line field to create a polyline shapefile of the video tracklines. XTools Pro (version 12.0) for Esri ArcGIS was used to rename, reorganize, and add new fields (Table Operations - Table Restructure) to the polyline shapefile, including an attribute for the station number of the video trackline (FIELD_NO), start time of the bottom video drift in UTC (STARTTIME), end time of the video drift in UTC (ENDTIME), Julian day of collection (JD), date of collection (DATE), year of collection (YEAR), trackline length in meters (LENGTH_M), camera used (CAMERA), survey ID (FA_ID), sampling device used to collect the video (DEVICE_ID), and survey vessel (VEHICLE_ID). XTools Pro changed some of the bottom video trackline features from singlepart to multipart features if they overlapped or intersected themselves. To correct this, the Spatial Join tool was run with the original bottom video tracklines shapefile as the input features and the updated tracklines shapefile as the join features using the intersect match option to add the updated attributes to the original singlepart features. Unnecessary fields created when running the Spatial Join tool were deleted (i.e., Join_Count and TARGET_FID). The Spatial Join tool was then run with the bottom photos shapefile to assign the station number (FIELD_NO) of the video trackline based on any intersecting bottom photos. Three video tracklines did not intersect any bottom photos; two of these videos (clip 027 and clip 028) were of the water column and were deleted, while one (clip 004) was assigned a station number using information from the data acquisition log. Unnecessary fields created when running the Spatial Join tool were deleted (i.e., Join_Count and TARGET_FID). The bottom video tracklines shapefile was then joined with the trackline points shapefile to add the start and end times of the video drifts (STARTTIME and ENDTIME, respectively), Julian day of collection (JD), and date of collection (DATE). Next, the trackline length (LENGTH_M) was calculated using the Calculate Geometry tool (Property=Length; Use coordinate system of the data frame=WGS 1984 UTM Zone 19N; Unit=Meters). Finally, the bottom video line name (LINENAME) was updated to match the new video filenames, which include the field activity identifier, camera, and date and start time in the ISO 8601 standard in the filename.
