Sediment Physical Properties Data from Sediment Cores Collected in March 2012 Along the Northern Chandeleur Islands, Louisiana (U.S. Geological Survey Field Activity Numbers 12BIM01)

Scientists from the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center collected a set of sediment cores from the back-barrier environments along the Chandeleur Islands, Louisiana, in March 2012. The sampling efforts were part of a larger USGS study to evaluate effects on the geomorphology of the Chandeleur Islands following the construction of an artificial sand berm to reduce oil transport onto federally managed lands. The objective of this study was to evaluate the response of the back-barrier tidal and wetland environments to the berm. This report serves as an archive for sedimentological and radiochemical data derived from the sediment cores. The data described in this report is available for download.2012年3月，美国地质调查局（U.S. Geological Survey, USGS）圣彼得堡海岸与海洋科学中心的科研人员沿路易斯安那州尚德莱尔群岛的障壁后环境采集了一套沉积岩芯。此次采样是美国地质调查局一项大型研究的组成部分，该研究旨在评估为减少石油向联邦管辖土地运移而修建人工沙堤后，尚德莱尔群岛的地貌形态所受影响。本研究的目标为评估障壁后潮汐与湿地环境对该沙堤的响应情况。本报告作为本次研究获取的沉积岩芯相关沉积学与放射化学数据的存档资料，其中记述的数据均可下载获取。
