J. Denny W. Baldwin W. Schwab R. Morton P. Gayes N. Driscoll W. Barnhardt 2007 <p>The inner continental shelf off northern South Carolina is a sediment-limited environment characterized by extensive hardground areas, where coastal plain strata and ancient channel-fill deposits are exposed at the sea floor. Holocene sand is concentrated in large shoals associated with active tidal inlets, an isolated shore-detached sand body, and a widespread series of low-relief sand ridges. The regional geologic framework is a strong control on the production, movement and deposition of sediment. High-resolution geologic mapping of the sea floor supports conceptual models indicative of net southwestward sediment transport along the coast.</p> application/pdf 10.1061/40926(239)169 en American Society of Civil Engineers Geologic framework of the long bay inner shelf: implications for coastal evolution in South Carolina text
