Description:
Abstract:
The U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center (WHCMSC) completed a bathymetric and shallow seismic-reflection survey during the period of June 9, 2021 to June 24, 2021 in water depths from 2 m to 30 m for a portion of the outer Cape Cod nearshore environment between Marconi and Nauset Beaches. The products from this survey will help to support white shark research on their shallow-water behavior in the dynamic nearshore environment at Cape Cod National Seashore (CACO). CACO visitors’ safety is threatened by interactions between the public and white sharks. This project provides CACO with baseline data and information on nearshore white shark habitat, specifically in the nearshore shoreface, bathymetric trough, and longshore bar. This data release provides the geophysical data collected from outer Cape Cod during USGS Field Activities 2021-002-FA in 2021.
Purpose:
This dataset is used to display the locations of sound velocity profiles collected with AML Minos X SVP (sound velocity profiler) during survey 2021-004-FA from outer Cape Cod, 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 raw 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 2021-004-FA was provided to the USGS from the National Park Service, Cape Cod National Seashore. Additional information on the field activities associated with this project are available at https://cmgds.marine.usgs.gov/fan_info.php?fan=2021-004-FA

Data_Quality_Information:
Logical_Consistency_Report:
Sound velocity profiles were acquired with an AML Minos X Sound Velocity Profiler (SVP).
Completeness_Report:
A total of 45 sound velocity profiles were collected during survey 2021-004-FA and are included in this dataset. Profiles are named sequentially beginning with the casts collected on the first day of surveying. Any gap in sequential numbering indicates invalid or unusable profile data (there is no data for casts 3, 9-11, 14, 19, and 25).
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 athwartship and mounted atop the aft end of cabin. 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 SVP deployment locations. DGPS positions are horizontally accurate to 0.5 - 2 meters. However, offsets from the location of the SVP 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 2 m.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Minos X depths are calculated by the AML SeaCast software (version 4.4); the software converts 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.

Sound speed profiles were collected to correct refraction artifacts in the multibeam bathymetric data that can occur due to changes in the speed of sound throughout the water column.
Process_Step:
Process_Description:
The Minos X hand-deployed sound velocity profiler was deployed approximately 1-2 hours to collect sound velocity, pressure, and temperature profiles in the water column. 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.

Process_Step:
Process_Description:
A Python script (plotMVPsql_2021_004_py3) was used to read the ASVP data and plot the sound speed profile as speed of sound (meter/second) versus depth (meters). Position, Date, Time, and Profile ID were pulled from the ASVP header and written into the image (PNG) for reference. Within the same script, the Position, Julian day, Time, and Profile ID were also imported to a geospatial SQLite (version 3.26.0) 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. Lastly, the Python script also reformats the parsed ASVP data into sound velocity files that are ready for import into CARIS HIPS to be used for correcting refraction artifacts typically found in swath bathymetry data. The contact person for this and all subsequent processing steps below is Seth Ackerman.
