Bayesian assessment of northern Alaskan chronological issues: Implications for future research

Cultural interaction and exchange across the Bering Strait of northern Alaska played a central role in the emergence of Arctic maritime adaptations. Yet poor chronological control limits our ability to explore processes of cultural change over the last 5000 years. We address this problem by synthesizing the available radiocarbon record for the region, carrying out Bayesian analysis of a regional radiocarbon database, and analyzing the BAR-1 (Birnirk) site using new dates published in this paper. Our synthesis and our illustrative analysis of the BAR-1 site highlights several intriguing temporal and spatial trends with implications for interaction between cultural groups. Our analysis also underscores the uncertainty associated with dating cultural phases and identifies specific areas where additional research is needed to further our understanding of cultural interaction in this complex region.
