Description:
Abstract:
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
Purpose:

Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Real-Time Kinematic GPS (RTK-GPS), Differential GPS (DGPS) and Wide Area Augmentation System-enabled DGPS (DGPS+WAAS) data were collected during this survey using an Ashtech ProFlex 800, Coda Octopus F185R, Hemisphere DGPS, and Sitex Marine Electronics Depthfinder receivers. The data were processed and recorded using navigation software from HYPACK, Inc (<http://www.hypack.com>). These data were typically incorporated into the geophysical data during acquisition and logged to these HYPACK files in the event that post-processing the horizontal and vertical positional information was necessary. The DGPS positional accuracy is estimated to be within 3-5 m; WAAS enable DGPS accuracy is estimated to be less than 3 m and the accuracy of RTK-GPS is estimated to be less than 1 m.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Real-Time Kinematic GPS (RTK-GPS) height data were collected, processed and recorded using navigation software from HYPACK, Inc (<http://www.hypack.com>). The data were logged to these HYPACK files so that they could be post-processed to extract the RTK-GPS heights and provide improved vertical accuracy for the swath bathymetric data during post-cruise processing (if needed to replace zone tidal model). RTK-GPS provides accuracies on the order of tens of centimeters (<http://www.navcen.uscg.gov>).

Raw navigation data were saved in HYPACK format (<http://www.hypack.com>). File name convention is LLL_TTTT.DDD, where LLL is the HYPACK line number, TTTT is the 24 hour time for the beginning of the file, and DDD is the Julian day (JD). Times were recorded in UTC (Coordinate Universal Time). During survey 2014-002-FA, HYPACK version 14.0.9.47 was used.
Process_Step:
Process_Description:
Raw HYPACK navigation files were transferred from the navigation acquisition computer to a centralized data server on the survey vessel for accessibility and archival. The filenames are in the format of linenumber_starttime.julianday. For example, filename 24_1816.203 represents planned survey HYPACK line number 24, start time 1816 and Julian Day 203. Times are recorded in UTC (Coordinate Universal Time). Filenames that start with 000 have no geophysical data line associated with them because they were logging navigation associated with sediment samples and bottom photographs.

Overview_Description:
Entity_and_Attribute_Overview:
The times recorded in the navigation file are in UTC. Keywords and the information they provide are as follows:
FTP: The first record located at the top of the header used to identify the file format.
VER: HYPACK version number.
INF: General survey information filled in by the data technician. This typically contains the vessel name, agencies involved with the survey, and the location of the survey.
ELL: Ellipsoid information. The name of the ellipsoid followed by the semi-major axis in meters and the flattening ratio.
PRO: Project information record where TME indicates Transverse Mercator and the central meridian of -75 indicates UTM, zone 18.
DTM: Datum transformation record
GEO: Geoid model. Blank if not present.
HVU: Horizontal and Vertical Units (meters)
TND: Survey time and date in UTC.
DEV 0: For survey 2014-002-FA: Indicates that lines collected with device designation 0 are lines of Differential Global Positioning System (DGPS) collected with the Hemisphere DGPS receiver. When sampling began and geophysical surveying ended on Julian Day 203. The Hemisphere DGPS was disabled at DEV 0 and enabled as a DEV 5 with an offset to relocate the GPS at the stern of the vessel where the sampler was being deployed. All files ending in ***.203 and later will have a DEV 5.
OFF: Device Offsets in the format "OFF dn n1 n2 n3 n4 n5 n6 n7" where dn = device number; n1 = starboard or port offset (positive starboard); n2 = forward or aft offset (positive forward); n3 = height (antenna) or depth (transducer draft) offset; n4 = yaw rotation angle (positive for clockwise rotation); n5 = roll rotation angle (port side up is positive); n6 = pitch rotation angle (bow up is positive); n7 = device latency in seconds.
PRD: Private Device Data, which has multiple formats depending onf the type of device generating the data. KTD for is example is a Kinematic Tide Datum File.
DDT: identifies the device that the computer clock is being synchronized to.
DEV 1: For survey 2014-002-FA: Indicates that the device designation 1 is a web-interface that is relaying the hypack feed from the acquisition van to a bridge monitor and the processing van.
DEV 2: For survey 2014-002-FA: Indicates that the lines with device designation 1 are lines of Real Time Kinematic Global Positioning System (RTK-GPS) data collected with the Ashtech ProFlex 800 GPS RTK receiver. This device recorded the RTK-GPS heights and was capable of recording antenna elevations above a vertical datum (Kinematic Tide Datum).
DEV 3: For survey 2014-002-FA: Indicates that the lines with device designation 3 are lines of fathometer information collected by a Sitex DepthFinder. This device is utilized by the MVP30 to transmit depth measurements ensuring that the sound velocity profiler would not deploy below 4 meters from the sea floor.
DEV 4: For survey 2014-002-FA: Indicates the device designation 4 are NMEA Output lines.
DEV 5: For survey 2014-002-FA: indicates that the device designation 5 are also lines of Hemisphere DGPS, but only during 3 days at the end of the survey when samples were being collected. The DEV 0 hemisphere was disables and became DEV 5 with an offset (-13) to the stern as a backup for sample location.
LIN 2: planned line data follows
PTS: planned line waypoints (easting and northing, UTM, zone 18N, meters)
LBP: planned line begin point (easting and northing, UTM zone 18N, meters)
LNN: planned line name
