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.

佐治亚大学的凯瑟琳·纳波拉（Katharine Napora）女士和维克多·汤普森（Victor Thompson）博士将研究气候转变对居住在乔治亚海岸沿线的美国原住民群体的影响，从4500年到3100年前。这项研究将阐明沿海壳环村遗址的遗弃与环境变化之间的时间关系。对佐治亚海岸人类环境相互作用动态的这项研究有助于更广泛地了解对主要气候变化的反应，长期的环境趋势以及美国东南部关键过渡期间的差异弹性，该项目将有助于有关此类群体如何适应剧烈生态变化的信息。这项工作还将为本科研究人员提供机会，从而通过在项目过程中举办的外展和教育活动来了解东南海岸的深层文化和环境历史，以了解东南海岸的深厚文化和环境历史。为了进行这项研究，该项目将检查壳中部的末端放射性碳，并从该地区发掘的样品中创建6000年的秃头柏树环宽。树突年代学是一种独特的方法，适合于人类时间范围内经历的事件的综合研究，并在深度时间框架的背景下被理解。该研究使用树环数据结合建模大型终端晚期古站的最终职业日期，旨在重建气候条件，并为佐治亚州北部海岸提供更精确的壳环放弃时间表。这项研究将在此期间生成有关环境状况的年度尺度数据，并将建模现存和新的放射性碳的日期，其日期是与壳牌中间站点相比，与树突年代学的序列进行比较，从而更加精确地理解了这种基础和沉降传统的转变，这反映了NSF的合法传统和宽广的依据。 标准。
