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）数据的解译成果。其衍生数据集采用ESRI形状文件（ESRI shapefile）多边形矢量格式，旨在表征纽约湾（New York Bight）范围内内陆架区域的更新世（Pleistocene）冰水砾质砂沉积（经改造形成一系列低幅细砂横向床形）的空间分布特征。该数据集有助于解析内陆架地层演化、区域沉积物输运系统，以及陆架内部结构对海岸过程的影响。
