Location and analysis of grain-size data sampled from vibracores collected by the U.S. Geological Survey within Apalachicola Bay, Florida, 2007 (APP-07_GrainSize, points)

In 2007, the U.S. Geological Survey collected 24 vibracores within Apalachicola Bay, Florida. The vibracores were collected using a Rossfelder electric percussive (P-3) vibracore system during a cruise on the R/V Gilbert. Selection of the core sites was based on a geophysical survey that was conducted during 2005 and 2006 in collaboration with the National Oceanic and Atmospheric Administration’s (NOAA) Coastal Services Center (CSC) and the Apalachicola Bay National Estuarine Research Reserve. Available data include the vibracore data logs and photographs, select seismic-reflection profiles (from the geophysical survey), and core-derived data including: grain size analyses, radiocarbon ages, microfossil counts, and sedimentological interpretations. The long-term goal of this study is to provide maps, data, and assistance to the Apalachicola Bay National Estuarine Research Reserve in their effort to monitor and understand the geology and ecology of Apalachicola Bay Estuary. These data will inform coastal managers charged with resource preservation.

2007年，美国地质调查局（U.S. Geological Survey）在佛罗里达州阿巴拉契科拉湾采集了24根振动岩芯（vibracore）。本次采样依托搭载于R/V Gilbert号科考船的Rossfelder电动冲击式（P-3型）振动岩芯系统完成。岩芯点位的筛选基于2005至2006年间与美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）海岸服务中心（Coastal Services Center，CSC）及阿巴拉契科拉湾国家河口研究保护区合作开展的地球物理勘探结果。
本数据集包含的可用数据包括振动岩芯日志与影像照片、精选的反射地震剖面（seismic-reflection profiles），以及由岩芯衍生的各类分析数据，具体涵盖粒度分析、放射性碳定年结果、微古生物计数与沉积学解释。
本研究的长期目标是为阿巴拉契科拉湾国家河口研究保护区提供地图、数据与技术支持，助力其监测并解析阿巴拉契科拉湾河口的地质与生态特征。相关数据将为负责海岸资源保护的管理者提供决策依据。
