Abstract

Instruments that record the concentration of suspended sediments and particles by the photoextinction method are coupled with electromagnetic current meters to sense the dispersal of coastal sediments. These instruments have been employed as part of the study of the infamous New York Bight, the area that extends from Montauk Point, Long Island, to Cape May, New Jersey.

It has been determined that sediment transport occurs within the New York Bight only during major storms, usually northeasters, according to a report by the Atlantic Oceanographic and Meteorological Laboratories (part of NOAA) in Miami. The results of this study and of a study planned for the northern California coast may form the basis of new sedimentary models. It may be possible to determine the rate and the extent of horizontal sand movement.
