Stable and Radio-Isotope Chemistry of the Nuvuk Mortuary Assemblage, Point Barrow, Alaska

该项目需要对阿拉斯加巴罗角Nuvuk墓地遗址的人类遗骸进行加速器放射性碳测年（AMS）和稳定同位素分析。这是对Dennis O'Rourke和M. Geoffrey Hayes （OPP-0732846）进行的基因研究的补充，他们的研究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和北极东部的现代群体之间的关系，这些墓葬正在迅速侵蚀到北冰洋。先前的研究表明，东北极群体起源于巴罗角；然而，Nuvuk墓地缺乏必要的时间控制来锚定史前遗传变异，并提供重建迁徙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测年和稳定碳氮同位素分析。前一种程序将建立急需的时间控制，而后一种程序将允许研究人员在研究的时间跨度内检查饮食模式。Nuvuk的研究是与Barrow社区合作进行的，包括Barrow高中学生参与的研究活动。

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.
