To address these concerns the U.S. Geological Survey, in cooperation with the Massachusetts Office of Coastal Zone Management (CZM), comprehensively mapped the Cape Cod Bay sea floor to characterize the surface and shallow subsurface geologic framework. Geophysical data collected include swath bathymetry, backscatter, and seismic reflection profile data. Ground-truth data, including sediment samples, underwater video, and bottom photographs were also collected. This effort is part of a long-term collaboration between the USGS and the Commonwealth of Massachusetts to map the State’s waters, support research on the Quaternary evolution of coastal Massachusetts, the influence of sea-level change and sediment supply on coastal evolution, and efforts to understand the type, distribution, and quality of subtidal marine habitats. This collaboration produces high-resolution geologic maps and Geographic Information System (GIS) data that serve the needs of research, management and the public. Data collected as part of this mapping cooperative continue to be released in a series of USGS Open-File Reports and Data Releases (https://www.usgs.gov/centers/whcmsc/science/geologic-mapping-massachusetts-seafloor). This data release provides the geophysical and geologic sampling data collected in Cape Cod Bay during USGS Field Activities 2019-002-FA and 2019-034-FA in 2019. Purpose: This dataset contains a polyline shapefile representing the trackline navigation for approximately 4912 kilometers of multibeam echo sounder bathymetry and backscatter data collected by the U.S. Geological Survey during survey 2019-002-FA in Cape Cod Bay, Massachusetts. This information can help spatially correlate the bathymetry and backscatter data with other geophysical data. Supplemental_Information: Support for 2019-002-FA was provided to the USGS from the Massachusetts Office of Coastal Zone Management. Additional information on the field activities associated with this project are available at https://cmgds.marine.usgs.gov/fan_info.php?fan=2019-002-FA and https://cmgds.marine.usgs.gov/fan_info.php?fan=2019-034-FA.

Acquisition may have been suspended briefly during file changes or for longer periods during turns and system calibration, malfunction, or troubleshooting system issues. Any gaps between the polyline features in this shapefile reflect those time periods where data were not recorded. This trackline shapefile was generated from the bathymetry data processed in Computer Aided Resource Information System (CARIS) Hydrographic Information Processing System (HIPS; version 11.3) using the Hysweep HSX raw sonar files. Note that backscatter imagery (processed in QPS FMGT version 7.8.9) was created using the Reson UI s7k raw files (M_ and S_ survey lines) that were collected simultaneously with the Hysweep HSX files. This polyline shapefile only represents the HSX tracklines which are generally the same extent as the s7k tracks. The s7k (M_ and S_) sonar files are mostly coincident with each other, although they can become unsynchronized. The small timing offset only affects the timing of survey file changes and the resulting line names, not the quality of the data. Completeness_Report: Data were collected on the following dates: 20190801-20190829 (Julian day 213-241); bathymetry data from 20190801 (Julian day 213) and 20190827 (Julian day 239) includes data processed for performing the patch test to calibrate the multibeam sonar but these data were not incorporated into the final bathymetry dataset or the backscatter mosaic. Data collected during some turns and along lines that extend beyond the area of a continuous geophysical survey data were also excluded from the final bathymetry dataset and backscatter mosaic. However, the patch test tracklines and tracklines that extend beyond the survey area are all included in this shapefile. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Navigation data were acquired using the WGS 84 coordinate system with an Applanix POS MV Wavemaster (model 220, V5), which blends Global Navigation Satellite Systems (GNSS) with acceleration data from a Motion Reference Unit (MRU) and GPS azimuthal heading. The POS MV was configured with two AeroAntenna Technologies GPS antennas located at either end of a 2-m baseline, which was oriented fore and aft and mounted atop the MBES pole, approximately midships on the port side of vessel. DGPS positions are horizontally accurate to 0.5 - 2 meters, but accuracy improves to less than 10 cm after post-processing with Applanix POSPac (version 8.1).

Vessel navigation and attitude data were acquired using an Applanix POS MV Wavemaster (model 220, V5). An AML Micro X SV mounted on the sonar bracket monitored sound speed near the sonars during acquisition, and an AML MVP30 moving vessel profiler (MVP) or an AML Minos X sound velocity profiler (SVP) was deployed from the stern of the vessel to collect water column sound speed profiles at 1 to 4 hour intervals while underway (See shapefile 2019-002-FA_MVPSVP_data.shp available from the larger work citation). The Reson SeaBat User Interface (version 5.0.0.6) was used to control the sonars, as well as to monitor and record the sonar data. Hypack/Hysweep (version 2019, 19.X.X.X) was also used for record and monitor the sonar data. The SeaBat User Interface logged the navigation, attitude, bathymetry, time-series backscatter, and water column data to s7k format files for each sonar. The line files were created by the Reson UI using the following naming convention: YYYYMMDD_HHMMSS_M/S. The line files were appended with a "M" or "S" suffix to denote the port (primary) and starboard (or secondary) sonar heads, respectively. Hypack Hysweep 2019 also was used to log the navigation, attitude, and bathymetry data for both sonars to a single HSX format file. Hypack Hysweep filenames have the format 'YYYYMMDD_HHMMSS_LLL_HHMM', which prepends the Reson filename (YYYYMMDD_HHMMSS) to the Hypack Hysweep filename (LLL_HHMM), where LLL indicates the three digit planned line number and HHMM is the UTC time. The Hysweep HSX data were used to produce the final processed bathymetry grid. The Reson SeaBat User Interface s7k data were used to produce the final processed backscatter mosaic. This dataset was created from the Hysweep HSX data in CARIS HIPS (version 11.3). Process_Step: Process_Description: PROCESSING STEP 1: CARIS HIPS DATA PROCESSING. Multibeam bathymetry processing within CARIS HIPS (version 11.3) post-survey consisted of the following flow: 1) A vessel configuration file was created in CARIS for the HSX sonar files (WarrenJrHSX_4-24-2020.hvf) which included relevant, linear and angular installation offsets for each T20-P unit as well as vendor specified uncertainty values for each of the survey sensors. 2) A CARIS HIPS project (version 11.3) was created with projection information set to Universal Transverse Mercator (UTM) Zone 19N, WGS84 using the vessel configuration file from step 1. 3) Each HSX file was imported to the new CARIS project using the Import/Conversion Wizard. 4) Delayed heave data from raw POS MV files were used to update HIPS survey lines using the import auxiliary data function. 5) Post-processed navigation, vessel attitude, and GPS height data from POSPac SBET files, and post-processed RMS attitude error data from POSPac smrmsg files were used to update HIPS survey lines using the import auxiliary data function. 6) Navigation source was set to Applanix SBET, and navigation was reviewed and edited as needed using the Navigation Editor tool. 7) Georeference Bathymetry was done to apply the sound velocity corrections from the final SVP file (2019-002-FA_SVP_MASTER_v2.svp) containing all the sound velocity profiles collected during the survey, specifying the nearest in time method, delayed heave source, and use surface sound speed. 8) 5-m resolution Swath Angle Weighted (SWATH) surfaces were created to incorporate all the files as they were processed, and the SWATH surfaces were reviewed for inconsistencies and anomalies. 9) The swath and subset editors were used to remove spurious points through manual editing and filter application, and the refraction editor was used to adjust sound speed values in areas where sound velocity data did not adequately correct depth profiles, which were obviously influenced by local anomalies in speed of sound through the water column. The steps described above were performed by Brian Andrews and Bill Danforth. The contact person for this and all subsequent processing steps below is Seth Ackerman.
