Description:
Abstract:
The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy in the fall of 2012. The U.S. Geological Survey conducted cruises during the summers of 2014 and 2015 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. Geophysical data collected during the cruises include swath bathymetric, sidescan sonar, chirp and boomer seismic reflection profiles, grab sample and bottom photograph data. 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/, https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-002-FA and https://cmgds.marine.usgs.gov/fan_info.php?fan=2015-001-FA. Data collected during the 2014 survey can be obtained here: https://doi.org/10.5066/F7MW2F60
Purpose:
This dataset contains trackline navigation for approximately 5,500 km of swath interferometric bathymetry data collected by the U.S. Geological Survey during cruise 2015-001-FA along the Delmarva Peninsula, MD and VA. This information can help spatially correlate the bathymetric data with other data in the GIS.

Data_Quality_Information:
Logical_Consistency_Report:
These swath bathymetry data were collected at 200 meter line spacing. The M/V Scarlet Isabella can only survey in water depths greater than 8 meters, so there are some gaps in the survey lines where the vessel had to avoid crossing shallow shoals. Most of the gaps were planned with breaks in tracklines or maneuvers around the shoals. Most of the data were acquired roughly parallel to the orientation of Assateague Island at an average speed of 5 knots. Line numbering begins at line 1 and ends at line 183. Any spurious bathymetry navigation data points were removed during processing.
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 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 data were acquired in WGS 84 coordinate system with an Applanix Wavemaster POS MV, which blends Global Navigation Satellite Systems (GNSS) with acceleration data from a Motion Reference Unit (MRU) and GPS azimuthal heading. The POS MV uses a dual antenna array with a designated primary and secondary antenna. Positions from the primary (forward) Applanix antenna were sent via Ethernet satellite link (from a KVH Mini-VSAT Broadband receiver) to shore stations in MD and VA. Returned Radio Technical Commission for Maritime Services (RTCM) 3.1 position corrections were passed through to the Applanix Wavemaster and applied to the Submetrix System for Real Time Kinematic (RTK) position solutions (accurate to less than 1 m, horizontally). Backup Differential Global Positioning System + Wide Area Augmentation System (DGPS+WAAS), which is accurate to within 2 m horizontally, were also acquired using an Ashtech Proflex 800; however, the backup DGPS and WAAS data were not implemented into the bathymetry data since the primary POS MV positioning provided continuous data throughout the survey. Positional offsets from the primary antenna to the MRU were corrected within the BathySwath acquisition software.

USGS used a 234 kHz Systems Engineering and Assessment Ltd. (SEA) SWATHplus-M (now Bathyswath) interferometric sonar pole-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 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:
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 (vers. 3.10.6.0). This step and subsequent steps were performed by Wayne Baldwin.

Process_Description:
A new Computer Aided Resource Information System (CARIS) Hydrographic Information Processing System (HIPS) project (vers. 9.0.14) was created with projection information set to Universal Transverse Mercator (UTM) Zone 18N, WGS 84. 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.

Process_Step:
Process_Description:
AWK, Python and Shell scripts were used to extract and reformat the navigation fixes stored in the CARIS HIPS database and add them to a geospatial SQLite (version 3.7.9) database. The processing flow for this step follows:
A. Extract navigation for each line in CARIS HDCS directory using the CARIS program printfNav for all the lines. (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 directory of TXT navigation files for each survey line in the CARIS project.
B. The output TXT files from the printfNav process are parsed to remove rejected navigation records then reformatted into CSV files containing additional fields for survey ID, vessel name and system name using Shell and AWK scripts.
C. A Python script (pySQLBathNav) runs on each reformatted CSV file parsing the file from each record and adding points to a SQLite database (which is created if it does not already exist). The pySQLBathNav script creates both point and trackline navigation for each survey line.
D. When all of the survey lines have been processed into SQLite database, a polyline shapefile is exported from the database using the spatialite_tool command (Spatialite version 3.0.1).
Steps B, C and D were all run within a shell script called printfnavconv.
