Textural description of surface sediment samples collected in March/April 2014 and October 2014 from Chincoteague Bay, Virginia and Maryland (U.S. Geological Survey Field Activity Numbers 14CTB01, and 14CTB22).

Scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center conducted a seasonal collection of surficial sediments from Chincoteague Bay and Tom's Cove, located between Assateague Island and the Delmarva Peninsula in March/April 2014 (2014-301-FA) and October 2014 (2014-322-FA). The sampling efforts were part of a larger U.S. Geological Survey study to assess the effects of storm events on sediment distribution. The objective of this study was to characterize the sediments of Chincoteague Bay in order to create baseline conditions to incorporate with hydrodynamic and sediment transport models in order to evaluate pre- and post-storm (Hurricane Sandy) change. This report serves as an archive for sedimentological data derived from the surface sediment. Data are available for a seasonal comparison between March/April 2014 and October 2014. Downloadable data are available as Excel spreadsheets (sediment samples) and as JPEG files (maps). Additional files include: detailed results of sediment grain size analyses, and formal Federal Geographic Data Committee metadata (data downloads).美国地质调查局（U.S. Geological Survey）圣彼得堡沿海与海洋科学中心的科研人员，于2014年3月/4月（采样批次编号2014-301-FA）及2014年10月（采样批次编号2014-322-FA），对坐落于阿萨蒂格岛（Assateague Island）与德尔马瓦半岛（Delmarva Peninsula）之间的钦科蒂格湾（Chincoteague Bay）和汤姆湾（Tom's Cove）开展了表层沉积物的季节性采集工作。此次采样工作是美国地质调查局一项更大规模研究的组成部分，该研究旨在评估风暴事件对沉积物分布的影响。本研究的目标是对钦科蒂格湾的沉积物进行特征表征，以建立基准环境条件，进而结合水动力与沉积物输运模型，评估飓风桑迪（Hurricane Sandy）前后的沉积物变化情况。本报告作为表层沉积物沉积学数据的存档载体。数据集包含2014年3月/4月与2014年10月的季节性对比数据。可下载的数据格式包括Excel电子表格（沉积物样品数据）与JPEG格式文件（地图）。附加文件还包括沉积物粒度分析的详细结果，以及正式的联邦地理数据委员会（Federal Geographic Data Committee）元数据（数据下载包）。
