Linear Shoals on the Atlantic Inner Continental Shelf, Florida to Long Island

Résumé du livre

The inner Atlantic continental shelf from Long to Florida is characterized by fields of linear, northeast trending shoals. The shoals exhibit up to 30 ft of relief, have side slopes of a few degrees and extend for tens of miles. Clusters of linear shoals merge with the shoreface in water as shallow as 10 ft. Most of the shoals out to depths of 120 ft have been examined by means of seismic profiling, precision depth profiling, grab sampling, coring; current monitoring has been conducted on a few shoals. These inner-shelf sand bodies or shoalscan be grouped as arcuate (inlet and cape-associated) and linear. Linear shoals may radiate from estuary mouths, as a second order structure on arcuate, inlet-associated shoals, or may occur on the open coast. Linear shoals on the open coast may be shoreface-connected or isolated. All linear shoals of the open coast form a small angle (most
