Coastal Bathymetry and Backscatter Data Collected in August 2019 from Cedar Island, Virginia

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS SPCSMC), conducted a geophysical survey of Cedar Island, Virginia, August 2019. During this study, multibeam bathymetry and backscatter data were collected aboard the R/V Sallenger, while single-beam bathymetry were collected aboard a towed seismic sled. Efforts were supported by the Coastal Sediment Availability and Flux (CSAF) Project which aims to quantify how much sediment is available in coastal systems and measure sediment exchanges between barrier island environments to improve prediction of coastal response to storms and sea-level rise.

位于佛罗里达州圣彼得斯堡的美国地质调查局圣彼得斯堡海岸与海洋科学中心（U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, USGS SPCSMC）的科研人员，于2019年8月对弗吉尼亚州锡达岛开展了地球物理勘测。本次研究中，科研团队搭载"萨林杰号"研究船（R/V Sallenger）采集了多波束测深与反向散射数据，并通过牵引式地震橇采集了单波束测深数据。本项工作得到了海岸沉积物供给与通量（Coastal Sediment Availability and Flux, CSAF）项目的资助，该项目旨在量化海岸系统内的沉积物供给量，测定障壁岛环境间的沉积物交换过程，从而提升风暴与海平面上升背景下海岸响应的预测精度。如需了解数据采集与/或处理方法的更多细节，请参阅相关元数据。
