Sediment Grain-size Data from sediment grab samples and box cores collected in May 2014 from Barnegat Bay, New Jersey (U.S. Geological Survey Field Activity Numbers 2014-310-FA).

Barnegat Bay, located along the eastern shore of New Jersey, was significantly impacted by Hurricane Sandy in October 2012. Scientists from the U.S. Geological Survey (USGS) developed a multidisciplinary study of sediment transport and hydrodynamics to understand the mechanisms that govern estuarine and wetland responses to storm forcing. This report details the physical and chemical characteristics of surficial and downcore sediments from two areas within the bay. Eleven sites were sampled in both the central portion of the bay near Barnegat Inlet and in the southern portion of the bay in Little Egg Harbor. Laboratory analyses include Be-7, Pb-210, bulk density, porosity, x-radiographs, and grain-size distribution. These data will serve as a critical baseline dataset for understanding the current sedimentological regime and can be applied to future storms for understanding estuarine and wetland evolution. This report serves as an archive for sedimentological and radiochemical data derived from the surface sediments and box cores. Downloadable data are available as Excel spreadsheets, PDF files, and JPEG files, and includes sediment core data plots and x-radiographs, as well as, physical-properties, grain-size, alpha-spectoscopy, and gamma-spectroscopy data. Federal Geographic Data Committee metadata are available for analytical datasets in the data downloads page of this report.

巴内加特湾（Barnegat Bay）位于新泽西州东海岸，2012年10月的飓风桑迪对其造成了显著影响。美国地质调查局（U.S. Geological Survey, USGS）的科研人员开展了一项针对沉积物输运与水动力过程的多学科研究，旨在阐明调控河口与湿地对风暴胁迫响应的内在机制。本报告详细记述了该海湾内两个区域的表层与岩心沉积物的物理及化学特征。研究团队在巴内加特湾入口附近的湾中部，以及小埃格港所在的湾南部共布设11个采样点位并完成采样。实验室分析项目涵盖铍-7（Be-7）、铅-210（Pb-210）、容重、孔隙度、X射线影像（x-radiographs）以及粒度分布。上述数据将作为理解当前沉积学动态的关键基准数据集，可应用于后续风暴事件研究，以解析河口与湿地的演化历程。本报告作为表层沉积物与箱式岩心（box cores）相关沉积学及放射化学数据的归档载体。可下载数据涵盖Excel电子表格、PDF文件及JPEG文件格式，包含沉积物岩心数据图件、X射线影像，以及物理性质、粒度、α能谱分析和γ能谱分析数据。本报告的数据下载页面提供了分析数据集对应的联邦地理数据委员会（Federal Geographic Data Committee, FGDC）元数据。
