This project entails accelerator radiocarbon dating (AMS) and stable isotope analysis of human remains from the Nuvuk Cemetery site at Point Barrow, Alaska. It is complimentary to genetic research directed by Dennis O'Rourke and M. Geoffrey Hayes (OPP-0732846) designed to establish the relationship between burials from this prehistoric cemetery, which are rapidly eroding into the Arctic Ocean, and modern groups now living both along the North Slope of Alaska and in the eastern Arctic. Previous research suggests that eastern Arctic groups originated at Point Barrow; however Nuvuk Cemetery lacks the chronological control necessary to anchor prehistoric genetic variability and provide the temporal framework needed to reconstruct migratory events. Here, the research team will extract and purify bone collagen from 100 individuals for AMS dating and stable carbon and nitrogen isotope analysis. The former procedure will establish much needed temporal control while the latter will allow the investigators to examine dietary patterning over the temporal span of the study. The research at Nuvuk is in collaboration with the community of Barrow, including the participation of Barrow high school students in research activities.

该项目需要对阿拉斯加州巴罗角Nuvuk墓地的遗骸进行加速器放射性碳年代测定和稳定同位素分析。 这是对丹尼斯·奥罗克和M.杰弗里·海耶斯（Geoffrey Hayes）（编号0732846）的设计旨在建立这个史前墓地的墓葬与现在生活在阿拉斯加北坡沿着和北极东部的现代群体之间的关系。 以前的研究表明，北极东部群体起源于点巴罗，但Nuvuk墓地缺乏必要的时间控制锚史前遗传变异，并提供重建迁移事件所需的时间框架。 在这里，研究小组将从100个个体中提取和纯化骨胶原，用于AMS测年和稳定的碳和氮同位素分析。 前一个程序将建立非常需要的时间控制，而后者将允许研究人员在研究的时间跨度内检查饮食模式。 Nuvuk的研究与巴罗社区合作，包括巴罗高中学生参与研究活动。
