What does this data set describe?
    Title: CERCMR82_10: USACOE ICONS Cores, Central New Jersey
    Abstract:
    About 1800 square kilometers of the central New Jersey inner shelf between Avalon and 7.5 kilometers north of Barnegat Inlet was surveyed to assess and quantify marine sand and gravel resources 6 meters below the sea floor. The primary data consist of 1133 kilometers of high-resolution seismic reflection profiles, limited side-scan sonar coverage, and 97 vibracores, a maximum of 6 meters long. Limits of the surveys were generally from about -7 meter depth contour seaward to about the -21 meter depth contour, a maximum of some 22 kilometers offshore. Analyses of the survey data reveal that an estimated 172 million cubic meters of suitable sand is present in 15 different locales. Most of the sand is contained in linear and arcuate shoals that appear to be Holocene to modern in age. The shoals are resting on a pre-Holocene age substrate composed of sedimentary deposits of fluvial origin. These deposits show evidence of past subaerial erosion.
