Hurricane Sandy washover deposit data from southern Long Beach Island, New Jersey: Grain-size, elevations, and graphic core logs

Sedimentologic and topographic data from Hurricane Sandy washover deposits were collected from Southern Long Beach Island, New Jersey, in order to document changes to the barrier-island beaches, dunes, and coastal wetlands due to Hurricane Sandy and subsequent storm events. These data will provide a baseline dataset for use in future coastal change descriptive and predictive studies and assessments. The data presented here were collected as part of the U.S. Geological Survey's Barrier Island and Estuarine Wetland Physical Change Assessment project, which aims to assess ecological and societal vulnerability that results from long- and short-term physical changes to barrier islands and coastal wetlands. In April 2015, approximately two and a half years after Hurricane Sandy's landfall on 29 October 2012, washover deposits were photographed and described, and sediment cores, sediment samples, and surface elevations were collected.

本数据集收录了采集自新泽西州长滩岛南部的飓风“桑迪”风暴冲溢沉积（washover deposits）相关沉积学与地形数据，旨在记录飓风“桑迪”及后续风暴事件对障壁岛（barrier island）海滩、沙丘与滨海湿地造成的变化。该数据集将作为基准数据集，用于未来海岸变化的描述性、预测性研究与评估工作。本次发布的数据采集自美国地质调查局（U.S. Geological Survey）的“障壁岛与河口湿地物理变化评估”项目，该项目旨在评估由障壁岛及滨海湿地的长期与短期物理变化所引发的生态与社会脆弱性。2015年4月，即飓风“桑迪”于2012年10月29日登陆约两年半后，研究人员对风暴冲溢沉积进行了拍照与沉积学描述，并采集了沉积岩芯（sediment cores）、沉积物样品（sediment samples）与地表高程（surface elevations）数据。
