Accurate data and maps of sea-floor geology are important first steps toward protecting habitat, delineating marine resources, and assessing environmental changes due to natural or human effects. Initiated in 2003, the primary objective of the Geologic Mapping of the Massachusetts Sea Floor program is to develop regional geologic framework information for the management of coastal and marine resources. The program is focused on the inshore waters (primarily 5-30 meters deep, although the region surveyed in this field activity includes waters up to 90 meters deep) of Massachusetts. This dataset, collected aboard the Ocean Survey Vessel (OSV) Bold as part of the Geologic Mapping of the Massachusetts Sea Floor Program, is from U.S. Geological Survey (USGS) sampling survey 2012-035-FA (August 21-27, 2012) by the USGS Woods Hole Coastal and Marine Science Center and the Massachusetts Office of Coastal Zone Management with partners from the Massachusetts Bays Program, the Massachusetts Department of Environmental Protection, the Massachusetts Division of Marine Fisheries, and the U.S. Environmental Protection Agency. During the survey, surficial sediment samples and bottom still and video imagery were collected in Ipswich Bay and Massachusetts Bay, Massachusetts.
This dataset is used to display the locations of bottom videos acquired with a Kongsberg Simrad OE1365 video camera on the SEABed Observation and Sampling System (SEABOSS) collected during USGS survey 2012-035-FA. Video data serve as a means to visually classify grain size and are especially important for sites where no physical sediment sample was collected.
To view the bottom videos, see the Coastal and Marine Geology Program Video and Photograph Portal (Golden and others, 2015; link available from the cross-reference citation). Bottom still imagery was also taken at each station (see shapefile 2012-035-FA_photos.shp available from the larger work citation). Physical sediment samples were also collected at many stations and analyzed for grain size (see shapefile 2012-035-FA_samples.shp available from the larger work citation) and benthic infauna (see report by the Massachusetts Office of Coastal Zone Management [2013] available from the cross-reference citation).

All bottom videos were acquired using a Kongsberg Simrad OE1365 video camera on the SEABOSS. The station numbers (FIELD_NO) were determined before the survey and are not necessarily in sequential order of when they were occupied. Gaps in sequential station numbers exist as not all planned stations were occupied during the survey. Two stations (stations 164 and 179) have two SEABOSS bottom video tracklines, so the tracklines were named "a" and "b" to indicate back-to-back deployments at the same station (e.g., line names 164a and 164b). 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.
Three hundred fifty stations were occupied within the study area. Two stations (stations 164 and 179) have two video tracklines from two deployments of the SEABOSS at the station, so the tracklines were named "a" and "b" to indicate back-to-back deployments at the same station (e.g., line names 164a and 164b). Some videos were clipped to the duration that the camera was within view of the sea floor. A total of 352 video tracklines are included in this dataset.
Navigation for survey 2012-035-FA used DGPS. The DGPS was set to receive fixes at a two-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, not the SEABOSS sampler. The antenna was mounted at the top of the vessel's A-frame from which the sampler was deployed, within a few meters of the sampler (+/- 3 meters). No layback or offset was applied to the recorded position. In addition to the +/- 3-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 10 meters. At times the ship was moving so slowly that the resolution of the DGPS makes a trackline appear to double back on itself.

Bottom video was acquired using the InterOcean SEABOSS. 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. The InterOcean SEABOSS incorporates a downward-looking video camera (a Kongsberg Simrad OE1365 in this setup), a still camera, and a modified Van Veen sediment sampler. The elements of this particular SEABOSS system are held within a stainless-steel frame that measures 1.15 x 1.15 meters. The frame has a stabilizer fin that orients the system as it drifts over the seabed. The OSV Bold occupied one of the target stations and the SEABOSS was deployed off the vessel's A-frame on the stern of the ship. 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 sea floor was sampled with the SEABOSS's integrated Van Veen grab. Sediment samples were only attempted in areas where collecting a sample would not damage the SEABOSS; 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. The system was then raised and recovered to the deck of the survey vessel. Bottom video was recorded from the Kongsberg Simrad OE1365 downward-looking video camera on Digital8 tapes and backup DVDs. DGPS navigation from a Garmin GPSMAP 76CSx receiver was logged through a Microsoft HyperTerminal (version 5.1) session on a Dell Latitude D820 laptop computer running Windows XP SP2 via serial cable and was also recorded to the audio channel of the video files. The DGPS was set to receive fixes at a two-second interval in geographic coordinates (WGS 84). Log files were saved approximately for each Julian day in ASCII text format.

DGPS navigation from a Garmin GPSMAP 76CSx receiver was logged through a Microsoft HyperTerminal (version 5.1) session on a Dell Latitude D820 laptop computer running Windows XP SP2 via serial cable. The DGPS was set to receive fixes at a two-second interval in geographic coordinates (WGS 84). Log files were saved approximately for each Julian day in ASCII text format. Dates and times were recorded in Coordinated Universal Time (UTC). The original log files were reformatted into log files by full Julian day based on UTC time. An AWK script (awkseth.gprmc.12035.awk) was run on the log files to parse for the GPRMC navigation string and create ASCII Comma Separated Value (CSV) text files. The output files were merged and then reformatted using an AWK script (nav_time_reformat.awk), creating a final processed navigation file for the entire sampling survey.

Bottom video was originally recorded on Digital8 tapes and backup DVDs. Each tape was played back and imported to a separate iMovie project (version iMovie HD 6). Within iMovie, each individual SEABOSS deployment was separated as its own video clip. In order to batch export all of the clips for a particular iMovie project, a Perl script (parse_iMovie_XML_Mar2014.pl) was run to parse the iMovie XML project file and create a shell script (do_convert.sh). Each line of the shell script was a one-liner command to run the program FFmpeg (version 0.11) with video and audio codec parameters (libx264 and libfaac, respectively) and output a video file named by station number. The shell script was run for each iMovie project creating individual video clips for each station in the M4V file format.

A drift log was created by parsing and reformatting the manually kept Microsoft Excel survey log for station number, start date and time in UTC, and end date and time in UTC for each video drift. The accuracy of the drift log was evaluated by comparing the manually entered start and end times to their companions extracted from the audio channel of the video files using the program Horax (version 0.1). Manually recorded times for some stations were replaced with more precise values obtained from the audio channel. The bottom video for four stations (stations 16, 88, 214, and 274) was not recorded on the Digital8 tapes but was available on backup DVDs in the VOB file format. The DVD videos have an overlay of the Global Positioning System (GPS) time, date, latitude, and longitude, as well as a user-input station number. The DVD videos for these four stations were viewed in VLC media player (version 2.2.4) to verify the start and end times as shown on the overlay. This process step and all subsequent process steps were performed by the same person, Emily Huntley.

Navigation was not recorded by the Microsoft HyperTerminal session at station 77 due to a system malfunction. Instead, five fixes were extracted from the audio, which has the navigation embedded in it, of the video file for station 77. An additional known fix was identified based on the sediment sample site recorded in a log maintained by the U.S. Environmental Protection Agency during the survey. These known fixes were interpolated in Esri ArcGIS (version 10.3.1) to get one-second fixes. The Construct Points editing tool was used to create evenly spaced points along the line segments between the known fixes so that a point was created for each second. The coordinates of the points were calculated using the Calculate Geometry tool (Property=X Coordinate of Point and Y Coordinate of Point; Use coordinate system of the data source=WGS 1984; Unit=Decimal Degrees). The interpolated points were exported as a CSV file and added to the one-second navigation file.

A polyline shapefile was created by using a Python script (seaboss_trackline_creator_v1_1.py) to join the drift log with the one-second navigation file. The Python script reads the start and end times from the drift log, extracts the navigation points that fall within those start and end times, and then creates a polyline shapefile from the navigation points with a unique line for each video drift.
