Here, we present the North American Repository for Archaeological Isotopes (NARIA), the largest open-access compilation of previously reported isotopic measurements (n = 28,374) from bioarchaeological samples in North America (i.e., Canada, Greenland, Mexico, and the United States of America) covering a time-frame of more than 12,000 years. This database consists of stable (δC, δN, δO) and radiogenic (Sr/Sr) isotope measurements from archaeological human, animal, and plant sources and their corresponding contextual information (e.g., location, chronology, cultural affiliation, etc.). This synthesis of isotopic measurements and other forms of data presents significant research potential for investigating past human lifeways, particularly in the realms of paleomobility, paleoenvironment, and paleodiet. Additionally, it serves to pinpoint spatial and temporal data gaps, offering valuable insights for future research directions.
在此，我们展示了北美考古同位素库（NARIA），这是北美（即加拿大、格陵兰、墨西哥和美利坚合众国）生物考古样本中先前报告的同位素测量数据（n = 28,374）的最大开放获取汇编，涵盖超过12000年的时间范围。该数据库包含来自考古人类、动物和植物来源的稳定同位素（δC、δN、δO）和放射性同位素（Sr/Sr）测量数据及其相应的背景信息（如位置、年代学、文化归属等）。这种同位素测量与其他形式数据的综合，为研究过去人类的生活方式提供了巨大的研究潜力，特别是在古迁移、古环境和古饮食领域。此外，它有助于查明空间和时间数据缺口，为未来的研究方向提供有价值的见解。
