MS Katharine Napora and Dr. Victor Thompson of the University of Georgia will undertake research on the effects of climate shifts on the Native American groups who lived along the Georgia Coast from 4500 to 3100 years ago. This research will clarify the temporal relationships between abandonments of coastal shell ring village sites and environmental change. This research into the dynamics of human-environmental interactions on the Georgia Coast contributes to broader knowledge of responses to major climatic change, long-term environmental trends, and differential resilience during pivotal transitions in the southeastern U.S. This project will contribute information about how such groups were able to adapt to dramatic ecological shifts. This work will also provide opportunities both for undergraduate researchers to gain experience in dendrochronological methodologies and for the broader public to learn about the deep cultural and environmental history of the Southeast coast through outreach and educational events held during the course of the project. To conduct this research, the project will examine terminal radiocarbon dates from shell middens and create a 6000-year bald cypress ringwidth chronology from excavated samples from the region. Dendrochronology is a methodology uniquely suited for an integrated study of events experienced at the human timescale and understood within the context of a deep time framework. Using tree-ring data combined with modeling the final occupational dates of large terminal Late Archaic sites, this research aims to reconstruct climatic conditions and provide a more precise timeline of shell ring abandonments for the northern Georgia Coast. This study will generate annual-scale data on environmental conditions during this period and will model extant and new radiocarbon dates from shell ring and shell midden sites to compare to the dendrochronological sequence, allowing for greater precision in understanding the timing of shifts in subsistence and settlement traditions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

乔治亚大学的 Katharine Napora 女士和 Victor Thompson 博士将研究气候变化对 4500 至 3100 年前居住在乔治亚州海岸的美洲原住民群体的影响。这项研究将阐明沿海贝壳村遗址的废弃与环境变化之间的时间关系。这项对乔治亚州海岸人类与环境相互作用动态的研究有助于更广泛地了解美国东南部重大气候变化、长期环境趋势以及关键转型期间的差异恢复能力的反应。该项目将提供有关这些群体如何应对的信息能够适应剧烈的生态变化。这项工作还将为本科生研究人员提供获得树木年代学方法经验的机会，并为更广泛的公众提供通过项目期间举办的外展和教育活动了解东南海岸深厚的文化和环境历史的机会。为了进行这项研究，该项目将检查贝冢的最终放射性碳测年结果，并根据该地区出土的样本创建 6000 年秃头柏环宽年表。树木年代学是一种独特的方法论，适用于对人类时间尺度上经历的事件进行综合研究，并在深度时间框架的背景下进行理解。这项研究利用树木年轮数据，结合对大型晚期晚期遗址的最终占领日期进行建模，旨在重建气候条件，并为乔治亚州北部海岸提供更精确的贝壳环废弃时间表。这项研究将生成有关这一时期环境条件的年度规模数据，并对来自贝环和贝丘遗址的现有和新的放射性碳年代进行建模，以与树木年代序列进行比较，从而更准确地了解生存和定居变化的时间该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
