Description:
Abstract:
The northeastern North Carolina coastal system, from False Cape, Virginia, to Cape Lookout, North Carolina, has been studied by a cooperative research program that mapped the Quaternary geologic framework of the estuaries, barrier islands, and inner continental shelf. This information provides a basis to understand the linkage between geologic framework, physical processes, and coastal evolution at time scales from storm events to millennia. The study area attracts significant tourism to its parks and beaches, contains a number of coastal communities, and supports a local fishing industry, all of which are impacted by coastal change. Knowledge derived from this research program can be used to mitigate hazards and facilitate effective management of this dynamic coastal system.
This regional mapping project produced spatial datasets of high-resolution geophysical (bathymetry, backscatter intensity, and seismic reflection) and sedimentary (core and grab-sample) data. The high-resolution geophysical data were collected during numerous surveys within the back-barrier estuarine system, along the barrier island complex, in the nearshore, and along the inner continental shelf. Sediment cores were taken on the mainland and along the barrier islands, and both cores and grab samples were taken on the inner shelf. Data collection was a collaborative effort between the U.S. Geological Survey (USGS) and several other institutions including East Carolina University (ECU), the North Carolina Geological Survey, and the Virginia Institute of Marine Science (VIMS).
The high-resolution geophysical data of the inner continental shelf were collected during six separate surveys conducted between 1999 and 2004 (four USGS surveys north of Cape Hatteras: 1999-045-FA, 2001-005-FA, 2002-012-FA, 2002-013-FA, and two USGS surveys south of Cape Hatteras: 2003-003-FA and 2004-003-FA) and cover more than 2600 square kilometers of the inner shelf. Single-beam bathymetry data were collected north of Cape Hatteras in 1999 using a Furuno fathometer. Swath bathymetry data were collected on all other inner shelf surveys using a SEA, Ltd. SwathPLUS 234-kHz bathymetric sonar. Chirp seismic data as well as sidescan-sonar data were collected with a Teledyne Benthos (Datasonics) SIS-1000 north of Cape Hatteras along with boomer seismic reflection data (cruises 1999-045-FA, 2001-005-FA, 2002-012-FA and 2002-013-FA). An Edgetech 512i was used to collect chirp seismic data south of Cape Hatteras (cruises 2003-003-FA and 2004-003-FA) along with a Klein 3000 sidescan-sonar system. Sediment samples were collected with a Van Veen grab sampler during four of the USGS surveys (1999-045-FA, 2001-005-FA, 2002-013-FA, and 2004-003-FA). Additional sediment core data along the inner shelf are provided from previously published studies.
A cooperative study, between the North Carolina Geological Survey and the Minerals Management Service (MMS cores), collected vibracores along the inner continental shelf offshore of Nags Head, Kill Devils Hills and Kitty Hawk, North Carolina in 1996. The U.S. Army Corps of Engineers collected vibracores along the inner shelf offshore of Dare County in August 1995 (NDC cores) and July-August 1995 (SNL cores). These cores are curated by the North Carolina Geological Survey and were used as part of the ground validation process in this study.
Nearshore geophysical and core data were collected by the Virginia Institute of Marine Science. The nearshore is defined here as the region between the 10-m isobath and the shoreline. High-resolution bathymetry, backscatter intensity, and chirp seismic data were collected between June 2002 and May 2004. Vibracore samples were collected in May and July 2005.
Shallow subsurface geophysical data were acquired along the Outer Banks barrier islands using a ground-penetrating radar (GPR) system. Data were collected by East Carolina University from 2002 to 2005. Rotasonic cores (OBX cores) from five drilling operations were collected from 2002 to 2006 by the North Carolina Geological Survey as part of the cooperative study with the USGS. These cores are distributed throughout the Outer Banks as well as the mainland.
The USGS collected seismic data for the Quaternary section within the Albemarle-Pamlico estuarine system between 2001 and 2004 during six surveys (2001-013-FA, 2002-015-FA, 2003-005-FA , 2003-042-FA, 2004-005-FA, and 2004-006-FA). These surveys used Geopulse Boomer and Knudsen Engineering Limited (KEL) 320BR Chirp systems, except cruise 2003-042-FA, which used an Edgetech 424 Chirp and a boomer system. The study area includes Albemarle Sound and selected tributary estuaries such as the South, Pungo, Alligator, and Pasquotank Rivers; Pamlico Sound and trunk estuaries including the Neuse and Pamlico Rivers; and back-barrier sounds including Currituck, Croatan, Roanoke, Core, and Bogue.
Purpose:
Swath and single-beam bathymetric data were collected along with sidescan-sonar, boomer and chirp sub-bottom geophysical data along the inner continental shelf study area. The single-beam and swath bathymetric data are used to define the regional seabed morphology within the study region. These data will augment the sidescan-sonar and chirp sub-bottom data.

Attribute_Accuracy_Report:
These data were acquired during four surveys: 1999-045-FA, 2001-005-FA, 2002-012-FA and 2002-013-FA. The 1999 data were collected with a single-beam Furuno echo-sounder and the 2001-2002 data with a SEA, Ltd. SwathPLUS 234-kHz bathymetric sonar.
Logical_Consistency_Report:
This grid represents interpolated data; processed to account for gaps that occurred along-track and between adjacent lines.
Completeness_Report:
All quality shore-parallel survey line bathymetric data that were collected within the inner continental shelf survey area north of Cape Hatteras to the Virginia border were incorporated in this grid. Soundings from both the single-beam and swath bathymetry surveys were processed and edited using the University of New Brunswick's Ocean Mapping Group (OMG) SwathEd multibeam processing software. Tielines (generally shore perpendicular) were not used in grid generation but used to verify tide corrections during post-processing.
The single-beam bathymetry trackline spacing was 300 meters and only provided depth data directly along the track resulting in data gaps between tracklines. The swath bathymetry trackline spacing was 300 meters resulting in roughly 30 - 40% coverage with the SwathPlus bathymetric sonar. Thus, there are data gaps between tracklines. Both datasets were interpolated to fill areas of NODATA and generate a continuous bathymetric surface.
Only the subset of bathymetry data collected north of Cape Hatteras has been included in this spatial dataset. Additional bathymetry data collected south of Cape Hatteras are included in a separate file available from: <https://pubs.usgs.gov/of/2011/1015/data/bathymetry/innershelf/shatt.zip>.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
All navigation data were acquired using the Differential Global Positioning Systems (DGPS). As such, horizontal accuracy is assumed to match that of DGPS: 1-3 meters (<http://www.navcen.uscg.gov>).
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Ship motion was recorded with a TSS DMS 2-05 Attitude Sensor, mounted on a head directly above the SwathPlus transducers. Navigation was recorded using Differential Global Positioning System (DGPS). Vertical accuracy is affected by the accuracy of both the navigation system and tidal measurements. DGPS vertical accuracy is assumed to be 0.2 meters. The data have been corrected for ship motion (roll, pitch, heave, and yaw). Tidal elevations were derived from the ADCIRC circulation model and referenced to Mean Sea Level (MSL). Changes in vessel draft due to fuel and water usage were not considered. The single-beam data was tide corrected and the draft of the transducer was accounted for during post-processing.

Process_Step:
Process_Description:
For single-beam data collected in 1999: Bathymetric data were extracted from the survey navigation and stored as an ASCII file, listing longitude, latitude, and depth in meters. These data were then reformatted and loaded into MATLAB (MathWorks, Inc.). The trackline spacing during data acquisition was 300 meters. Within MATLAB (MathWorks, Inc), a median filter with a 15 pixel boxcar size was applied to the bathymetric data to remove spurious spikes and anomalous readings. In order to account for the distance of the transducer below the sea surface, one meter was added to the bathymetric values. These data were then corrected for tidal fluctuations. The ADCIRC circulation model was used to extract tidal coefficients at the locations along the cruise track. These processed values were then exported from Matlab as an ASCII file listing longitude, latitude and depth in meters. This process step and all subsequent process steps were performed by Erika Hammar-Klose.

Process_Step:
Process_Description:
For swath bathymetry data collected in 2001 and 2002: Bathymetric data were corrected for variations in the speed of sound throughout the water column; sound velocity profiles were acquired throughout the survey area using an Applied MicroSystems SVPlus Sound Velocimeter. These data were downloaded and reformatted to the required format needed for use within University of New Brunswick's Ocean Mapping Group (OMG) SwathEd multibeam processing software. The raw SwathPlus data were "unraveled" and reformatted into the OMG format. This process creates several files on disk: 1) bathymetric soundings, 2) raw backscatter, 3) navigation, and 4) parameter files describing the configuration of the system (i.e. offsets between motion reference unit and DGPS antenna, etc). This process also incorporates the sound velocity profiles in order to properly trace the travel path of the acoustic rays.
Process_Date: 2004
Process_Step:
Process_Description:
The OMG formatted swath bathymetric data were then graphically edited using the SwathEd multibeam processing software. This enabled editing on a "ping-by-ping" basis, both in the across- and along-track dimension. Spurious or erroneous data were removed. The navigation data were also graphically examined for each line of data.
Process_Date: 2004
Process_Step:
Process_Description:
Navigation data output during the unravel were reformatted for entry into MATLAB. The time of day and position were used to extract the tidal elevation from within the ADCIRC circulation model. The ADCIRC circulation model is referenced to Mean Sea Level. The tidal elevations were then written to an ASCII file and reformatted to OMG format for use within SwathEd. The tidal data were then written into the headers of the OMG formatted files, using the 'mergeTide' command. (an example of SwathEd Commands:
binTide -year 2002 adcirc_ascii.txt tide.bin mergeTide -tide tide.bin *.merged
)
Process_Date: 2004
Process_Step:
Process_Description:
SwathEd Software was used to generate a blank grid at a 20m/pixel resolution into which the bathymetric data were written. make_blank areanumber_20m
SwathEd software was then used to grid the bathymetric data utilizing the 'weigh_grid' command. The tidal elevations stored in the file headers are used by default during the gridding routine.
weigh_grid -omg -butter -max_incidence 60 -maxdep -55 -mindep -4 -power 2 -cutoff 20 -lambda 10 areanumber_20m *.merged
Process_Date: 2004
Process_Step:
Process_Description:
The 20 meter gridded data were then viewed using the SwathEd Jview command. The PatchTool was used to assess the roll misalignment of the data; slight roll misalignment artifacts were visible in the gridded data. After the needed adjustments were recorded, the configuration and navigation were remerged with the OMG bathymetric data using the mergeNav command. (mergeNav -use_params 0 -nav *.nav -swath *.merged)
The remerged data were regridded for a second round of QC.
Process_Date: 2004
Process_Step:
Process_Description:
The bathymetric data to this point have been edited, checked for navigation errors and corrected for tides (relative to MSL). Sound velocity corrections have been applied, and the roll misalignment was rectified. The 20 meter gridded data were exported as xyz ASCII file using the SwathEd command 'r4toASCII'.
(r4toASCII areanumber_20m areanumber_20m.xyz)
Process_Date: 2004
Process_Step:
Process_Description:
The 20 meter xyz data for each area (both single-beam data and swath bathymetry data) were imported into a GRASS database as a sites file. Command s.in.ascii input=areanumber_20m.xyz sites=areanumber_20m fs=. This sites file was interpolated at 40 meters using a regularized spline with tension gridding technique. s.surf.rst input=areanumber_20m elev=areanumber_40m dmin=20 tension=200 smooth=40 npmin=200 theta=45 scalex=40 The interpolated raster file was exported as an ASCII raster file. r.out.arc input=areanumber_40m output=areanumber_40m.asc
Process_Date: 2004
Process_Step:
Process_Description:
Each area's .asc file was converted into an ESRI Grid using the ASCII to Raster utility in ArcToolbox (v9.1) under Conversion Tools > To Raster > ASCII to Raster.
Process_Date: 2004
Process_Step:
Process_Description:
The individual grids for areas 1 through 10 (surveys from 1999, 2001, and 2002) were combined in GRASS using the "merge" command and smoothed with neighborhood statistics (mean, circle, 5 cells).
Process_Date: 20041106
Process_Step:
Process_Description:
The final, merged grid was clipped in ArcToolbox (v9.1) using Analysis Tools > Extract > Clip. A polygon coverage of the sidescan sonar extent was used to clip interpolated data that exceeded the survey coverage extent.
