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 is used to display the locations of sound velocity profiles collected with an AML MVP30 (moving vessel profiler) and an AML Minos X SVP (sound velocity profiler) during survey 2019-002-FA in Cape Cod Bay, Massachusetts. The information contained within the sound velocity profiles is needed to account for refraction artifacts that may be present within raw swath bathymetric data. This dataset contains graphs of the sound velocity profile at each station location, as well as location in Geographic Coordinate System (GCS) WGS 84 latitude and longitude, time of day and date of collection. 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.

Completeness_Report: A total of 439 sound velocity profiles were collected during cruise 2019-002-FA and are included in this dataset. Profiles were renamed as a result of the extra processing done after sound velocity profile edits were done in CARIS HIPS (see process steps). The new file naming convention is based on the day and time the data were collected (see Entity and Attribute Information). Data were collected on the following dates: 20190801-20190829 (Julian day 213-241). 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. Positioning data from these GPS receivers were recorded using HYPACK software version 19.0.6.0 during the entire geophysical survey and positions were used for MVP and SVP deployment locations. DGPS positions are horizontally accurate to 0.5 - 2 meters. However, offsets from the location of the MVP30 deployment point and the GPS antenna were not measured, and therefore the horizontal accuracy of the sound velocity profile locations is considered to be within 20 m. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: MVP30 tow fish depths are calculated by the MVP acquisition software (version 2.391) and the Minos X depths are calculated by the AML SeaCast software (version 4.4); both softwares convert pressure sensor readings to depth using the standard formulas described in Fofonoff, N.P. and Millard, R.C., Jr., 1988, Algorithms for computation of fundamental properties of seawater, UNESCO Technical Papers in Marine Science, No. 44. The depths are estimated to be accurate to within 1 meter.

Process_Step: Process_Description: Sound velocity profiles were collected approximately every 1-4 hours using an AML MVP30. A computer controlled smart winch and deployment system allowed the free fall MVP profiler to be deployed while the vessel was underway at a user specified time interval. Data from the sound velocity profiler were written to a Kongsberg SIS format ASCII file (.asvp). The MVP was set to only collect data on the down-cast. Beginning on Friday August 2 at 1655 UTC, the MVP30 was replaced by an AML Minos X SVTP hand-deployed sound velocity profiler. The Minos X was deployed every 1-3 hours to collect sound velocity, pressure, and temperature profiles in the water column though the remainder of the survey. AML SeaCast software (v. 4.4) was used to read the profile data from the Minos X, export all raw cast data to an AML SeaCast (.csv) formatted file, then edit the sound velocity profile to preserve only the downcast portion of the deployment and export it to a Kongsberg SIS ASCII (.asvp) formatted file.

These corrected CARIS SVP files were then split into individual files for each sound velocity cast using the terminal 'csplit' command. >> csplit -f Leg1_ -n3 -k Leg1_SVP_Master.svp '/^Section/' '{300}' >> csplit -f Leg2_ -n3 -k Leg2_SVP_Master.svp '/^Section/' '{300}' Then the Python script MVP_plot_intoSQL_5May2021.py was used to create a plot for each sound velocity cast as a PNG image graph with speed of sound (meter/second) versus depth (meters). Position, Date, Time, and Profile ID were pulled from the SVP header line and written into the image for reference. The image files are named based on the date and time each sound velocity cast was collected. The same script parses the position, Julian Day, time, and Profile ID and entered it into a geospatial SQLite (version 3.36) database using the pyspatialite interface. The geographic positions were used to create point geometries for the station locations, and additional fields indicating survey ID, vessel ID, and device ID were added within the Python script. The individual .svp files (created by the csplit commands above) were then renamed to match the file names of the PNG files (based on the day and time of collection) using the following script: >> for f in Leg*.svp; do x=`awk 'NR==1{print "cast_"substr($2,1,4)substr($2,6,3)"_"substr($3,1,2)substr($3,4,2)substr($3,7,2)".svp"}' $f`; echo mv -v $f $x | sh; done And finally the CARIS SVP header was restored using the following command line scripts: >> for f in *.svp; do x=`echo "$f" ; cat $f`; echo "$x" > $f; done >> for f in *.svp; do x=`echo "[SVP_VERSION_2]" ; cat $f`; echo "$x" > $f; done Process_Date: 20210505 Process_Step: Process_Description: The sound velocity cast locations were exported from the SQLite database as Geographic Coordinate System (GCS, latitude and longitude) WGS 84 point features in ESRI Shapefile format using Spatialite-tools (version 5.0.1) using the spatialite_tool command in Terminal: >> spatialite_tool -e -shp 2019-002-FA_MVPSVP_data -d ./2019-002-FA-SQLdb_NEWSVP.sqlite -t MVPNav_pt -g geom_MVPnav -c CP1252 -s 4326 --type POINT Process_Date: 20211119 Spatial_Data_Organization_Information: Direct_Spatial_Reference_Method: Vector Point_and_Vector_Object_Information: SDTS_Terms_Description: SDTS_Point_and_Vector_Object_Type: Entity point Point_and_Vector_Object_Count: 439 Spatial_Reference_Information: Horizontal_Coordinate_System_Definition: Geographic: Latitude_Resolution: 0.0000054863 Longitude_Resolution: 0.000007073695 Geographic_Coordinate_Units: Decimal degrees Geodetic_Model: Horizontal_Datum_Name: D_WGS_1984 Ellipsoid_Name: WGS_1984 Semi-major_Axis: 6378137.000000 Denominator_of_Flattening_Ratio: 298.257224 Entity_and_Attribute_Information: Detailed_Description: Entity_Type: Entity_Type_Label: 2019-002-FA_MVPSVP_data.shp Entity_Type_Definition: Sound velocity locations collected in Cape Cod Bay during USGS Field Activity 2019-002-FA.
