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 Purpose: This dataset contains trackline navigation for approximately 4500 km of Swath interferometric bathymetry data collected by the U.S. Geological Survey during cruise 2014-002-FA along the Delmarva Peninsula, MD and VA. This information can help spatially correlate the bathymetric data with other data in the GIS.

Completeness_Report: This shapefile includes trackline navigation from all the swath bathymetric data that was collected within the survey area. However, only quality sonar data along the main survey lines were included in the final bathymetry grid. Noisy or poor quality data were not included in the grid, but the line navigation are included in this shapefile. Data from some survey lines were omitted where they overlapped with equal or better quality data (for example lines l148f2 and l19f3 are nearly collocated and only data from l148f2 are included in the grid because attitude positioning was not useable from l19f3). Data along tie and transit lines were not included in the final grid or in the navigation shapefile. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Navigation was acquired with a Coda Octopus F185 Differential Global Positioning System + Wide Area Augmentation System (DGPS+WAAS), which is accurate to + or - 1 to 2 meters, horizontally and RTK positioning from an Ashtech Proflex 800, which is accurate to less than 1-meter, horizontally. X,Y data are referenced to WGS84. The SWATHPlus transducers were mounted on a rigid pole, approximately 4.195 m below the water line, along the port side of the M/V Scarlett Isabella. The DGPS antenna and an Ashtech ProFlex 800 RTK GPS were located on the same pole approximately 4.6m above the sea surface. RTCM corrections were being delivered via the web (ethernet) to the Ashtech ProFlex 800 from shore stations in MD and VA (ethernet satellite link is from a KVH Mini-VSAT Broadband receiver). The RTK corrections were passed through to the F185R giving the submetrix system kinematic (x,y) positioning accuracy from Julian Day 170 and later. Lines (l1f1-l7f1) collected prior to 20140719 at 12:40:00 UTC were recorded with WAAS-enabled DGPS because the F185 was not receiving RTCM corrections from the Ashtech ProFlex800. Positional offsets from antennae to MRU were corrected within the SWATHPlus acquisition software. WAAS enabled DGPS accuracy is estimated to be less than 3 m and the accuracy of RTK-GPS is estimated to be less than 1 m.

Source_Citation_Abbreviation: raw bathymetry Source_Contribution: USGS used a 234 kHz Systems Engineering and Assessment Ltd. (SEA) SWATHplus interferometric sonar mounted on the port side of the M/V Scarlett Isabella. Survey lines were run at an average speed of 5 knots and were spaced 200 m apart in the nearshore to approximately 3-km apart in the offshore. Full data coverage was obtained for sidescan sonar data, but not for bathymetric data. The SEA SWATHplus-M operates at a frequency of 234 kHz and a variable range (increased or decreased manually depending on water depth, but generally 85 m on both sides). The system was operated with a transmit power of 80 percent, a transmit length of 43 cycles, and 4096 samples per channel. Sound-velocity profiles were collected continuously with an ODIM MVP30 moving vessel profiler. Tides were corrected using a zone tidal model with observed tides from gauges in Atlantic City, NJ; Lewes, DE; Chesapeake Bay-Bridge-Tunnel, VA; and Duck, NC. Process_Step: Process_Description: 2014-002-FA: Raw to Processed Conversion: Survey navigation information is stored within each raw (sxr) data file. Each raw SWATHPlus bathymetric sonar file (sxr) was converted to a SWATHPlus processed file (sxp) using SEA SWATHPlus Swath Processor (ver. 3.10.04).

Each SWATHPlus processed file (sxp) was imported to the new CARIS project using the Import/Conversion Wizard. Navigation was checked and edited as needed using the Navigation Editor tool.

The processing flow for this step follows: A. Extract navigation for each line in CARIS HDCS directory using Perl script do_CARIS_nav3.pl (which runs the CARIS program printfnav for all the lines in the HDCS dir). (Extracted navigation file is tab-delimited in format YYYY-JD HH:MM:SS:FFF DD.LAT DD.LONG SSSSS_VVVVV_YYYY-JD_LLLL AR where YYYY=year, JD=Julian Day, HH=hour, MM=minute, SS=seconds, FFF=fractions of a second, DD.LAT=latitude in decimal degrees, DD.LONG=longitude in decimal degrees, SSSSS=survey name, VVVVV=vessel name, LLLL=linename, AR=accepted or rejected navigation fix) This step creates the file combined.txt B. The navigation files extracted from CARIS HIPS contained 4-5 navigation fixes per second. These files were subsampled to produce files containing 1 fix per second using AWK to remove the fractions-of-a-second from the time column then grabbing the first occurrence of each second. AWK was also used to eliminate spurious fixes outside the survey area and reformat the navigation for conversion from comma separated value (CSV) data to Esri point feature class Process_Date: 2014 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Seth Ackerman Contact_Organization: U.S. Geological Survey Contact_Position: Geologist Contact_Address: Address_Type: mailing and physical address Address: 384 Woods Hole Rd.

The 'uniqueline' field was used to define which points were used to generate each polyline feature, and the first occurrence of fields 'linename', 'yrjd', 'jd_time', 'vessel', and the last occurrence of 'jd_tim_end' were chosen to be included as attributes in the output shapefile. The trackline shapefile was checked to ensure there were no severely spurious navigation fixes. XTools Pro (version 10.2.1257) for ArcGIS desktop was used (Table Operations - Table Restructure) to reorganize and add fields to the polyline shapefile's attribute table. The length field ('Length_km') was also added and then populated using 'Calculate Geometry' (Property = Length, Use coordinate system of the data frame = WGS 1984 UTM Zone 18N, Unit = Kilometers), which can be accessed by right clicking on the attribute field name in the table view.
