A Comprehensive Radiocarbon Date Database from Archaeological Contexts on the Coastal Plain of Georgia

This database consists of radiocarbon dates from archaeological contexts on the coastal plain of Georgia (samples from strictly geological contexts were not included). A comprehensive search was performed to find the original sources of dates reported for all archaeological sites in this area. As such, dates reported from any time (i.e., 1960s to the present) were incorporated, which includes dates with problems. Data were compiled by John Turck and numerous undergraduate work study and volunteer students over a large period of time (from January 2012 to July 2012, and from January 2013 to April 2013). John Turck added to and refined the dataset between May 2013 and February 2014. In general, the database was structured so the information could be easily input into CALIB's online calibration program. It includes information such as: sample IDs, raw age and standard deviation, delta 13 correction factor, adjusted age and standard deviation, site number and name, material, association, and references. Calibrated dates were not entered into this databse. These data can be used to aid in archaeological studies, refining our understanding of the timing of human occupations throughout the coastal plain, and especially in the coastal zone. These data can also be used to aid geological, and geomorphological studies. The nature of the data is such that it will need to be continually added to as new samples are processesd, and further refined as more information about dates entered previosuly are obtained. Note: The original radiocarbon date database contains sensitive information (i.e., the specific location of archaeological sites) that is for professional archaeologists only. If a professional archaeologist needs site location information, they can contact the Georgia Archaeological Site File.本数据库收录佐治亚州沿海平原考古背景下的碳十四测年数据（严格地质背景的样品未纳入统计）。研究团队对该区域所有考古遗址已报道测年数据的原始来源开展了全面检索，因此本数据集纳入了1960年代至今各时段发布的测年结果，其中亦包含存在瑕疵的测年数据。该数据集由约翰·特克（John Turck）与多名本科勤工俭学学生及志愿者耗时较长时段完成汇编，工作周期涵盖2012年1月至2012年7月，以及2013年1月至2013年4月；约翰·特克于2013年5月至2014年2月期间对本数据集进行了增补与优化。总体而言，本数据库的架构设计可便捷支持数据导入CALIB在线校准程序，数据集包含以下信息：样品编号、原始年龄及标准差、δ¹³C校正因子、校正后年龄及标准差、遗址编号与名称、测年材料、关联信息及参考文献。本数据库未收录校准后的测年数据。本数据集可用于辅助考古学研究，深化对佐治亚州沿海平原（尤其沿海地带）人类人居活动时序的认知；此外，该数据亦可服务于地质学与地貌学研究。本数据集的特性决定了其需要持续迭代更新：随着新样品完成测试，可补充纳入数据；同时，随着既往录入测年数据的相关信息进一步获取，数据集也需进一步优化完善。备注：本原始碳十四测年数据库包含敏感信息（即考古遗址的具体位置），仅供专业考古学家使用。若专业考古学家需要获取遗址位置信息，可联系佐治亚州考古遗址档案库（Georgia Archaeological Site File）。
