Apr 15, 2016 · The continental shelf that lies off South Carolina’s coast is part of a larger continental shelf that runs from Canada to Mexico. It is formed, in part, by a continuation of the sediments of the coastal plain that are covered by seawater.

A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an "insular shelf."

Figure 2: The continental margin off Cape Hatteras, North Carolina, is a classic shelf-slope-rise sequence, while most of the southeast U.S. continental margin is terrace-like, with prominent features such as the Blake Plateau, Blake Ridge, and Blake Escarpment, as well as the Charleston Bump.

Continental margins are the submerged edges of a continent, with areas known as the shelf (closest to shore), slope and rise. Water depths on margins extend to beyond 3 km. The map below shows the regions included in studies by students, followed by links to posters by region.

Jan 1, 2013 · The inner continental shelf off the northern Outer Banks of North Carolina was mapped using sidescan sonar, interferometric swath bathymetry, and high-resolution chirp and boomer subbottom profiling systems.

The Northeastern United States Continental Shelf (NEUS) is the large marine ecosystem designated by the United States National Oceanic and Atmospheric Administration that occupies the portion of the continental shelf of the Atlantic Ocean.

Location of known (red points) and suspected (green points) hard bottom habitats on the shelf off South Carolina. Station locations (triangles) for biological sampling are noted. Isobath indicates shelf edge.

Apr 16, 2022 · About 35 miles off the coast of North Carolina, the continental shelf dramatically slopes off from a depth of approximately 200 meters (656 feet) to more than 2,000 meters (6,561 feet) toward the continental rise and eventually the deep and flat abyssal plain.

Jun 25, 2020 · The low-accommodation setting of the continental shelf influences the stratigraphic record in several key ways: 1) the geometry of progradational coastal lithosomes; 2) the development of composite allogenic erosional surfaces; 3) the deposition of widespread, thin transgressive sand sheets; and 4) the restriction of thicker transgressive ...

Lithologic and stratigraphic data from rocks dredged from the continental shelf off Onslow Bay, North Carolina, provide surface control for seismic studies of the southeastern United States continental margin and help to explain the distribution of potentially economic phosphate-rich sediments on this shelf.
