In this study, we used stable isotope analysis and radiocarbon dating to study diet, mobility and chronology in two late medieval/historical coastal populations in northern Norway. We have shown that the individuals buried at Kirkegårdsøya date between 1331 and 1953 cal AD and had a homogenous marine diet, whereas the individuals buried at Gullholmen had a more heterogeneous diet, consisting of both terrestrial and marine proteins and date between 1661 and 1953 cal AD. We have demonstrated that reindeer protein was not an important part of their diet, and also discussed the importance of correcting for the marine reservoir effect in populations with a coastal subsistence. Our interpretation is that individuals buried at Kirkegårdsøya primarily belonged to a Coastal Sámi community, although Norwegians with a similar diet (and likely comprising a minor population in the area) cannot be ruled out. The more varied diet and mobility at Gullholmen could, as predicted, indicate that these individuals may have had a more diverse cultural affinity.

14-19 世纪芬兰北部沿海地区的饮食和文化特征

在这项研究中，我们使用稳定同位素分析和放射性碳测年来研究挪威北部两个中世纪晚期/历史沿海人口的饮食、流动性和年代学。我们已经证明，埋葬在 Kirkegårdsøya 的个体的日期在公元 1331 年到 1953 年之间，并且具有同质的海洋饮食，而埋葬在 Gullholmen 的个体的饮食更加异质，包括陆地和海洋蛋白质，日期在公元 1661 年到 1953 年之间. 我们已经证明驯鹿蛋白质不是他们饮食的重要组成部分，并且还讨论了纠正沿海生计人群的海洋水库效应的重要性。我们的解释是，埋葬在 Kirkegårdsøya 的人主要属于沿海萨米社区，尽管不能排除饮食相似的挪威人（并且可能包括该地区的少数人口）。正如预测的那样，Gullholmen 更多样化的饮食和流动性可能表明这些人可能具有更多样化的文化亲和力。
