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:
This grid represents the thickness of Quaternary sediment that are derived from analysis of the high-resolution seismic stratigraphy from the offshore and back barrier of North Carolina, from the Virginia border to Cape Lookout. The purpose of this data set is to map the thickness of Quaternary sediment above the top of Pliocene surface, Q0, using high-resolution seismic reflection data. These data were collected by the U.S. Geological Survey during twelve separate research cruises beginning in 1999 and ending in 2004. Approximately 13,600 line-km of high-resolution seismic reflection data were collected along the inner continental shelf and back barrier of North Carolina. These data will be used to characterize the subsurface of the seafloor for regional geologic framework investigations.

All of the original boomer and chirp seismic reflection data were used from U.S. Geological Survey inner shelf and back-barrier cruises 1999-045-FA, 2001-005-FA, 2001-013-FA, 2002-012-FA, 2002-013-FA, 2002-015-FA, 2003-003-FA, 2003-005-FA, 2003-042-FA, 2004-003-FA, 2004-005-FA, and 2004-006-FA.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
All boomer seismic lines from cruises 20010-13-FA, 2002-015-FA, 2003-005-FA, 2004-005-FA, and 2004-006-FA were positioned using Differential GPS (DGPS), with accuracy less than 5 meters. The position (layback) of the seismic source and receiver were not factored in the shotpoint position. The shotpoint position is relative to the position of the DGPS antenna, not the seismic source. Accuracy is assumed to be approximately 10 meters. For cruises 1999-045-FA, 2001-045-FA, 2002-012-FA, 2002-013-FA Teledyne Benthos (Datasonics) SIS-1000 chirp lines were positioned using Differential GPS (DGPS), with accuracy less than 5 meters. The position (layback) were factored in the shotpoint position. Uncertainty of layback corrections likely degraded accuracy. The shotpoint position is relative to the DGPS antenna. For cruises 2003-003-FA and 2004-003-FA a GPS receiver was mounted on the Edgetech 512i Chirp that was towed aft of the ship, one meter below the water surface and positioned without differential corrections resulting in about 30 meters accuracy. Therefore total uncertainty is approximately 30 meters.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Time zero of two-way travel time is relative to local sea surface. No corrections for sea level or tide variation (which is less than 2 meters offshore and less than one meter in Pamlico and Albemarle Sounds) are applied. Vertical resolution of less than one meter of the seismic reflection systems are less than the tidal ranges. Vertical accuracy of the final derived grid is also a function of the vertical accuracy of the NOAA Coastal Relief Model (CRM).

Process_Description:
For boomer data: Back-barrier (2001-013-FA, 2002-015-FA, 2003-005-FA, 2003-042-FA, 2004-005-FA) and inner shelf (1999-045-FA, 2001-005-FA, 2002-012-FA, 2002-013-FA) surveys were acquired using a Triton-Elics Delph Seismic acquisition system. The data were recorded in 16-bit integer standard SEG-Y format. DGPS navigation data were input in realtime to the acquisition system through HYPACK navigation software. The data are stored in the SEG-Y trace headers as UTM Zone 18 coordinates (meters). Back-barrier survey 2004-006-FA was acquired with a Delph Seismic Plus acquisition system with geographic coordinates in the SEG-Y header. For chirp data: Inner shelf chirp (Edgetech 512i) surveys 2003-003-FA and 2004-003-FA were acquired with an Edgetech JStar acquisition system with geographic coordinates in Edgetech JSF header. All JSF files were then converted to SEG-Y format. This process step and all subsequent steps were performed by the same person: David S. Foster.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The link to the data catalog was fixed. The source information was incomplete and had to be modified to meet the standard. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
