Location of radiocarbon age dates sampled from vibracores collected by the U.S. Geological Survey within Apalachicola Bay, Florida, 2007 (APP-07_AgeDates, 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）。这批振动岩芯采用Rossfelder电动冲击式（P-3型）振动岩芯系统，在R/V Gilbert号科考航次中完成采集。岩芯点位的选取依据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确定。可获取的数据包括振动岩芯数据日志与影像照片、精选的地震反射剖面（源自本次地球物理勘探），以及岩芯衍生数据，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。这些数据将为负责海岸资源保护的管理者提供科学参考依据。
