Brothers 2015 2.0 data release DOI:10.5066/F7MW2F60 Reston, VA U.S. Geological Survey https://doi.org/10.5066/F7MW2F60 The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy. A U.S. Geological Survey cruise was conducted in the summer of 2014 to map the inner continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal system evolution at storm-event and longer timescales. Data collected during the 2014 cruise include swath bathymetry, sidescan sonar, chirp and boomer seismic-reflection profiles, acoustic Doppler current profiler, and sample and bottom photograph data. Processed data in raster and vector format are released here for the swath bathymetry, sidescan sonar, and seismic-reflection profiles. More information about the USGS survey conducted as part of the Hurricane Sandy Response-- Geologic Framework and Coastal Vulnerability Study can be found at the project website or on the WHCMSC Field Activity Web pages: https://woodshole.er.usgs.gov/project-pages/delmarva/ and https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-002-FA This dataset is used to display the locations of sound velocity profiles (SVP) collected during a 2014 USGS cruise along the Delmarva Peninsula. 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 graphs of the sound velocity profile at each station location, as well as location in easting and northing (UTM, Zone 18N, WGS84, meters), time of day and date of collection 20140618 20140722 ground condition; data were not collected on 20140702-20140704; 20140709; and 20140714-20140715 due to weather.

All sound velocity profiles not associated with the patch test (588 total) collected during cruise 2014-002-FA are included in the Esri shapefile. Differential Global Positioning System (DGPS) navigation data were acquired with a Hemisphere receiver and recorded with HYPACK (www.hypack.com). The DGPS antenna located on the port-side of the acquisition van. Ship location was used for the sound velocity deployments. The MVP30 sound velocity profiler is autonomously deployed while the vessel is underway and is computer controlled through a smart winch and deployment system. Deployment positions are recorded from the hemisphere DGPS. 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 deployment at the smart winch and the DGPS antenna were not measured. The horizontal accuracy of the sound velocity locations is considered to be +/- 25 meters.

This information is used to help correct any refraction artifacts that may be present within the swath bathymetric data due to unaccounted for changes in the speed of sound throughout the water column. Sound velocity profiles were collected every 1-2 hours and sometimes more frequently using a Brooks Ocean Moving Vessel Profiler (see <http://www.brooke-ocean.com/mvp_main.html> for details). A computer controlled smart winch and deployment system allows the free fall fish to be deployed while the vessel is underway at a user specified time interval. A Sitex DepthFinder informs the MVP of the approximate water depth at time of deployment to ensure that the fish does not make contact with the seafloor. The sound velocity data are written to a Kongsberg SIS format ASCII file (.asvp). 2014 Seth Ackerman U.S. Geological Survey Geologist mailing and physical address

This allows the profile locations to be turned into a shapefile. A python script is used to plot the SOS profile as speed of sound (m/s) versus Depth (meters). Position, Date, Time, and Profile ID are pulled from the ASVP header and written into the image (PNG) for reference. 2014 Seth Ackerman U.S. Geological Survey Geologist mailing and physical address

The comma-separated text file was then imported to ArcMap 10.2.2 using 'Add XY data' and saved as points (UTM WGS84 Zone 18N) in the Esri shapefile format. The shapefile was then projected from WGS84 UTM Zone 18N to Geographic WGS84. Additional fields for survey ID, vessel ID, and device ID were added in ArcMap version 10.2.2 2015 Seth Ackerman U.S. Geological Survey Geologist mailing and physical address
