Description:

Abstract:

These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program. The primary objective of this program, initiated in 2003, is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human effects. The project is focused on the inshore waters (5-30 meters deep) of Massachusetts. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (<http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html>). This spatial dataset is from the study area located in Buzzards Bay and Vineyard Sound Massachusetts, and consists of ground-validation data which include the spatial extent of sea-floor sediment sample analyses, the location of sea-floor bottom photographs, and the tracklines along which sea-floor video was collected. These ground-validation (or ground-truth) data accompany a suite of high-resolution geophysical data, including swath bathymetry, sidescan-sonar backscatter intensity, and seismic-reflection data that were released in USGS Open File Reports 2012-1002 and 2012-1006. The sea-floor sampling data were collected during USGS survey 2010-005-FA in 2010 and cover more than 750 square kilometers of the inner continental shelf where the geophysical data were collected in 2009 and 2010.

Purpose:

This data set includes the tracklines (the linear extent) where seafloor photographs and video were acquired with the large SEABed Observation and Sampling System (SEABOSS, SEABOSS Mark II configuration) during USGS survey 2010-005-FA, conducted September 9-14, 2010 aboard the R/V Connecticut offshore Massachusetts in Buzzards Bay and Vineyard Sound. This data set was collected to ground-truth (verify) the acoustic data sets that were acquired during NOAA hydrographic survey H11319 (2004) and USGS geophysical surveys 09002 (2009) and 10004 (2010). Bottom photographs were also taken at each station occupied by the SEABOSS (see shapefiles BBVS_BottomPhotos_wBio.shp). Physical sediment samples were also collected and analyzed in the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center (see shapefile BBVS_SedimentSamples.shp).

Data_Quality_Information:

Logical_Consistency_Report:

Gaps in sequential video station numbers may exist. Some stations may have more than one video trackline.

Completeness_Report:

This dataset includes the video trackline locations for SEABOSS stations occupied during USGS survey 2010-005-FA aboard the R/V Connecticut within the Buzzards Bay and Vineyard Sound survey areas. Three-hundred and one stations were occupied within the study area during survey 2010-005-FA; some stations may have more than one video trackline and in these cases the tracklines are typically name "a" and "b" (e.g. Linename 40a and 40b exist for SEABOSS station 40). Sediment samples were obtained at 246 of these sites.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Navigation for survey 2010-005-FA used Differential Global Positioning System (GPS). The recorded position of each point along the video trackline is actually the position of the GPS antenna on the survey vessel, not the SEABOSS sampler. The SEABOSS was deployed approximately 5 meters astern of the GPS antenna off the ship's A-frame on the stern of the ship. No layback or offset was applied to the recorded position. In addition to the +/-5 meter offset the SEABOSS may additionally drift away from the survey vessel when deployed to the seafloor. Based on the various sources for horizontal offsets, a conservative estimate of the horizontal accuracy of the video trackline locations is 20-30 meters.

Process_Description:

DGPS navigation was logged through a Microsoft HyperTerminal (version 5.1) session on a HP laptop computer running Windows XP, SP2. Log files were saved for each sampling watch then reformatted into log files by Julian Day (e.g., JD252.txt) during post-processing. The AWK script awkseth.gpgga10005.sda was run on the group of Julian Day files creating a comma separated value (CSV) ASCII text file that parsed for the GPGGA navigation string (> awk -f awkseth.gpgga10005.sda JD*.txt > all_nav_10005.csv). The output file was then reformatted for the Python ground-truth toolset using the AWK script nav_time_reformat.awk (> awk -f nav_time_reformat.awk all_nav_10005.csv > 10005_UConn_ALLnav_final.csv), creating a final processed navigation file for the entire sampling survey (10005_UConn_ALLnav_final.csv).

Process_Description:

A "drift log" was created by parsing and reformatting the manually kept Microsoft Excel survey log 10005_seaboss_log_FINAL_DRAFT_v2.xls for SEABOSS station number, date, and the start and end time of each video drift. This log was checked and modified as a number of stations had unreliable start and end times based on the manually kept log. To check and determine correct start and end times, the program ffmpeg was used to create JPEG images of the first frame from each video file to verify the video start time (the DVD video has an overlay of the GPS time, latitude and longitude, as well as a user-input station number) and then another ffmpeg output calculated the length of each DVD video segment.

Process_Description:

Create polyline shapefile joining the SEABOSS drift time log with the navigation based on matching date and time fields using ArcGIS 9.3 ArcToolbox tool "z_SEABOSStools_demo2012 - 4. Seaboss_Trackline_Creator" (which uses the Python script "seaboss_trackline_creator_v1_1.py; inputs: drift file - drift_log_10005.csv; navfile - 10005_UConn_ALLnav_final.csv; outfile shapefile - vid_track_10005_v2.shp). The Python script reads the start and end times from the drift log file (drift_log_10005.csv) and extracts the navigation points that fall within those start and end times, then it creates a polyline shapefile from the points with a unique line for each SEABOSS drift site.

Process_Description:

XTools Pro (version 9.2) for ArcGIS desktop (version 10.1) was used to reorganize, delete unnecessary fields and add new fields to the polyline shapefile's attribute table (Table Operations - Table Restructure). Table attributes for the date ('Date'), survey ID ("SurveyID'), device used to collect the data ('DeviceID'), survey vessel name ('VehicleID') and imagelink ('ImageLink') were added and populated using the table editor in ArcMap (version 10.1). The length field ('Length') was populated using 'Calculate Geometry' (Property=Length; Use coordinate system of the data frame=WGS 1984 UTM Zone 19N; Unit=Meters), which can be accessed by right-clicking on the attribute field name in the table view. The attributes for Julian day ('JulDay'), year ('Year'), start time ('StartTime'), end time ('EndTime'), and SEABOSS station number ('Linename') were already populated.
