Description:
Abstract: In June 2022, the U.S. Geological Survey, in collaboration with the Massachusetts Office of Coastal Zone Management, collected high-resolution geophysical data, in Nantucket Sound to understand the regional geology in the vicinity of Horseshoe Shoal. 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, resolve the influence of sea-level change and sediment supply on coastal evolution, and strengthen efforts to understand the type, distribution, and quality of subtidal marine habitats. This collaboration produces high-resolution geologic 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.
Purpose: Water column speed of sound data were acquired periodically throughout the survey and used during collection and post-processing of Reson T-20P bathymetry data. Sound speed profile data are included in this publication as CARIS SVP format text files, PNG image plots of the profiles, and an ESRI point shapefile of the profile locations.
Supplemental_Information: Support for 2022-001-FA was provided to the USGS from the Massachusetts Office of Coastal Zone Management. Data were collected using the R/V Rafael, owned and operated by the USGS Woods Hole Coastal and Marine Science Center. Additional information on the field activity is available from https://cmgds.marine.usgs.gov/fan_info.php?fan=2022-001-FA.

Data_Quality_Information:
Logical_Consistency_Report: Sound velocity profiles were acquired with an AML-3 LGR or AML Minos-X CTDSV sensor.
Completeness_Report: A total of 46 sound velocity profiles were collected during cruise 2022-001-FA and are included in this dataset.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: When using the AML-3 LGR unit, navigation data were acquired by the Differential Global Positioning System (DGPS) inside the unit and directly inserted into the raw AML file header. When using the AML Minos-X, navigation data were recorded using an Applanix POS MV Wavemaster (model 220, V5) Global Navigation Satellite Systems (GNSS) and logged continuously in HYPACK (version 22.1.4.0). HYPACK targets were created at each cast location, coordinates were copied, and inserted manually into the AML SeaCast software (version 4.40) during download and export of each profile. The POS MV was configured with two AeroAntenna Technologies GPS antennas located at either end of a 2-m baseline, which was oriented athwartship and mounted atop the after end of the cabin. POS MV DGPS positions were obtained from the primary antenna (port end of the 2-m baseline configuration). DGPS positions are horizontally accurate to 0.5 - 2 meters. However, offsets between the deployment location and the primary antenna were not accounted for, so the sound velocity profile positions are considered to be accurate to within 2-5 m.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report: AML-3 LGR or Minos-X profile depths are calculated by either AML SeaCast (version 4.4) or Sailfish (version 4.4) software, respectively; 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:
PROCESSING STEP 1: COLLECT SOUND VELOCITY PROFILES.
Sound velocity profiles were collected 1-7 times per survey day using AML-3 LGR or Minos-X CTDSV sensors. Cast timing was determined depending on water column properties and the quality of real-time multibeam bathymetric data acquisition. The profiler sensor was hand-deployed from the after deck of R/V Rafael while the vessel was not making way. Once back on deck, data from the sensor were downloaded using either AML SeaCast (version 4.4; for AML-3 LGR) or Sailfish (version 4.4; for AML Minos-X) software, then files containing the full cast information were saved to the raw AML format (.csv) and downcast portions were saved to the CARIS SVP (.svp) format.

Process_Description:
PROCESSING STEP 2: SOUND VELOCITY PROFILE PROCESSING AND EXPORT FROM QIMERA.
Sound Velocity profiles for each day were imported and converted to Qimera (version 2.5.0) format using the Source/import/Caris svp menu. Each profile was reviewed for positional accuracy and erroneous depth/sound velocity values using the SVP editor. Incorrect records near the surface or within the water column were flagged using the "reject selection" context menu.
Edited SVP data were exported from Qimera using the Export/svp/export to CARIS SVP option, resulting in one svp text file that included all 46 svp casts.

PROCESSSING STEP 3: CREATE SVP PROFILE TEXT FILES, PNG IMAGES, AND POINT NAVIGATION FEATURE CLASS.
A python Jupyter notebook was used to read the single svp file exported from Qimera, split it by profile, and write out a CARIS SVP format file for each profile.
A second python Jupyter notebook utilized the python modules pandas (version 1.5.2), geopandas (version 0.12.1), shapely (version 1.8.5.post1), matplotlib (version 3.6.2), and sqlite3 (version 3.40.0) to read the individual svp files and create a PNG plot for each, containing speed of sound (meter/second) on the x-axis and depth (meters) on the y-axis. Position, Date, Time, and Profile ID were extracted from the SVP header line and written into the image as a title line for reference. The image files were named based on the date and time each sound velocity cast was collected. The latitude and longitude position, Cast ID, and Date/UTC time information for each cast, along with fields containing the Survey ID, Device ID, and Vehicle ID were appended as rows by profile to a Pandas dataframe during processing. After all profiles were processed, geopandas and shapely were used to create a point geometry column from the geographic station coordinates and the composite dataframe was imported to a geospatial SQLite database table using the pyspatialite interface.
Finally, the svp location SQLite database table was imported to QGIS (version 3.26) as a point feature layer and exported (Right click on database feature class > Data > Save Features As) to the ESRI point shapefile 2022-001-FA_SVP_data.shp.
