Surface sediment physical parameters data collected in August 2015 from Dauphin Island and the surrounding areas

Scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center collected 303 surface sediment samples from Dauphin Island, Alabama, and the surrounding water bodies in August 2015. These sediments were processed to determine physical characteristics such as organic content, bulk density, and grain-size. The environments where the sediments were collected include high and low salt marshes, over-wash deposits, dunes, beaches, sheltered bays, and open water. Sampling by the USGS was part of a larger study to assess the feasibility and sustainability of proposed restoration efforts for Dauphin Island, Alabama, and assess the island’s resilience to rising sea level and storm events. The data presented in this publication can be used by modelers to attempt validation of hindcast models and create predictive forecast models for both baseline conditions and storms. This study was funded by the National Fish and Wildlife Foundation, via the Gulf Environmental Benefit Fund. This report serves as an archive for sedimentological data derived from surface sediments. Downloadable data are available as Excel spreadsheets, JPEG files, and formal Federal Geographic Data Committee metadata (data downloads).

美国地质调查局（U.S. Geological Survey，简称USGS）圣彼得堡海岸与海洋科学中心的科研人员于2015年8月，从阿拉巴马州多芬岛及其周边水域采集了303份表层沉积物样本。研究人员对这批沉积物开展处理，以测定其有机质含量、容重、粒度等物理特征。本次采样覆盖的环境类型包括高盐沼、低盐沼、越流沉积体、沙丘、海滩、遮蔽海湾及开阔水域。USGS的此次采样工作，是一项大型研究的组成部分，该研究旨在评估阿拉巴马州多芬岛拟议修复工程的可行性与可持续性，并评估该岛应对海平面上升与风暴事件的恢复能力。本出版物刊载的数据可供建模人员用于验证后报模型，并可为基准条件与风暴场景构建预测预报模型。本研究由国家鱼类和野生动物基金会通过海湾环境效益基金资助。本报告作为表层沉积物沉积学数据的存档载体。可下载数据包含Excel电子表格、JPEG文件以及符合联邦地理数据委员会（Federal Geographic Data Committee）标准的正式元数据（数据下载包）。
