  Description:
    Abstract: "This study was initiated through a Memorandum of Agreement between the OBTF and the North Carolina Geological Survey in 1994 in order to identify potential beach nourishment sand resources and areas of potential hard bottom (environmentally sensitive areas) within the OBTF study area. The information collected includes seismic, side-scan, and vibracore data. The reports (see links below) summarize the geology of each area studied and provide information on the location and estimated amount of sand resources offshore of the erosional hotspots. This website contains a database of the vibracore data collected as part of this study. The interactive database shows core locations, core images, and textural (grain size) data derived from the core. Vibracores were collected during 8 weeks (July - August 1995) aboard the United States Army Vessel Snell from Oregon Inlet southward to Cape Hatteras, across Diamond Shoals, then westward to Ocracoke Inlet. Upon completion of the field-sampling program, all cores were transferred to the Coastal Plain Office of the North Carolina Geological Survey for processing. All cores were halved lengthwise, described, digitally imaged, and sampled to determine textural attributes. The digital images of each core were archived on CD-ROM and placed into the public domain at the Coastal Plain Office of the North Carolina Geological Survey. Core sediment samples were processed using standard laboratory methods by the Soils Testing Laboratory of the North Carolina Department of Transportation and textural attributes were compiled and archived on CD-ROM at the Coastal Plain Office of the North Carolina Geological Survey."
    Purpose: To identify potential beach nourishment sand resources and areas of potential hard bottom (environmentally sensitive areas) within the OBTF study area.
