Interpretation of the distribution of Pleistocene fluvioglacial gravelly sand deposits on the inner-continental shelf within the New York Bight, derived from seismic data collected by the U.S. Geological Survey, 1995 - 1999 (Esri polygon shapefile, Geographic, WGS84)

These data orginate from interpretations of seismic reflection and sidescan-sonar data. The derivative data are in an ESRI shapefile, polygon vector format and are intended to represent the distribution of Pleistocene fluvioglacial gravelly sand deposits (reworked into a series of low-amplitude, fine sand, transverse bedforms) throughout the inner-continental shelf within the New York Bight. These data are helpful in understanding the stratigraphic evolution of the inner-continental shelf, the regional sediment transport system, and the influence of the inner-shelf framework on coastal processes.本数据集源自地震反射（seismic reflection）与侧扫声呐（sidescan-sonar）数据的解译结果。其衍生数据采用ESRI形状文件（ESRI shapefile）多边形矢量格式，旨在表征纽约湾（New York Bight）内陆架范围内更新世冰水砾质砂沉积（经改造形成一系列低振幅细砂横向床形体）的分布情况。本数据集有助于理解内陆架的地层演化、区域沉积物输运系统，以及内陆架框架对海岸过程的影响。
