This dataset is used to display the locations of sound velocity profiles collected during USGS cruises within Vineyard Sounds and Buzzards Bay, MA. The information contained within the sound velocity profiles is needed to adequately account for refraction artifacts that may be present within raw swath bathymetric data. This dataset contains hyperlinks to graphs of the sound velocity profile at each station location, as well as location in easting and northing (UTM, Zone 19N, WGS 84, meters), time of day and date.

Differential Global Positioning System (DGPS) navigation data were acquired with a Communications Systems International (CSI), Inc. LGBX Pro receiver and recorded with HYPACK (www.hypack.com). The CSI received positions from a DGPS antenna located on the port, aft roof of the R/V Rafael cabin. Ship location was used for the sound velocity deployments. The SV plus v2 sound velocity profiler was hand deployed. Once the system reached bottom, positions were read from HYPACK and stored. DGPS accuracy is 1 to 3 meters, depending on the distance from a US Coast Guard coastal repeater station. However, offsets from the location of hand-deployment and the DGPS antenna were not measured, and the ship is allowed to drift during deployment which can last several minutes depending on water depth. The horizontal accuracy of the sound velocity locations is considered to be +/- 50 meters.
Water depth of the sound velocity profiles is recorded from the fathometer when GPS location of profile is recorded. Assumed vertical accuracy of the shipboard fathometer on the R/V Rafael is about .25 meters. However, vessel drift druing SVP deployment and recovery could add an additional meters of change in water depth. Water depth should be considered an approximation of water depth at the location of SVP deployment.
All sound velocity profiles not associated with the patch test collected during cruises 2011-013-FA and 2009-068-FA are included in this Esri shapefile. For cruise 2007-039-FA, only data from JD 309 and JD341 were needed to complete the bathymetry coverage over middle ground. JD 304 and JD 305 were excluded from this report because the data were redundant and ran for swath system comparison tests.
All sound velocity profiles were acquired with the same instrument; an Applied Microsystems SV plus v2.
