This report presents the initial results of a reconnaissance survey focused on identification of potentially suitable sand resources for beach nourishment along the North Carolina Outer Banks. Approximately 300 kilometers of high-resolution seismic-reflection profile data were collected along 15 separate tracklines offshore of Nags Head, North Carolina. These data have been interpreted, scale-rectified, and reduced to seismic stratigraphic sections. The seismic sections present a window to the shallow, subbottom geology. They depict several large shoals overlying a stacked series of tabular stratigraphic units. Each stratigraphic unit is 6 to 20 meters thick and all are bound by unconformity surfaces cut by multiple, relict (buried) stream valleys. The shoal features exhibit 3 to 15 meters of topographic relief, are common at water depths greater than 20 meters, and appear to be erosional in origin. By Stephen W. Snyder, 1993. 47 pages.
