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.

格鲁吉亚大学的凯瑟琳·纳波拉女士和维克托·汤普森博士将研究气候变化对4500年至3100年前居住沿着格鲁吉亚海岸的美洲土著群体的影响。本研究将厘清海岸贝壳环村落遗址废弃与环境变迁的时间关系。这项研究的动态人类与环境的相互作用在格鲁吉亚海岸有助于更广泛的知识，应对重大气候变化，长期的环境趋势，并在美国东南部的关键转型差异弹性这个项目将有助于这些群体如何能够适应巨大的生态变化的信息。这项工作还将为本科生研究人员提供机会，以获得树木年代学方法的经验，并为更广泛的公众通过项目期间举行的宣传和教育活动了解东南沿海的深层文化和环境历史。为了进行这项研究，该项目将检查来自贝壳贝冢的终端放射性碳年代，并从该地区挖掘的样本中创建一个6000年的秃柏环宽年表。树木年代学是一种独特的方法，适合于对人类时间尺度上经历的事件进行综合研究，并在深层时间框架的背景下进行理解。利用树木年轮数据结合建模的大型终端晚白垩世网站的最终职业日期，本研究旨在重建气候条件，并提供一个更精确的时间轴的壳环遗弃北方格鲁吉亚海岸。这项研究将生成这一时期环境条件的年度规模数据，并将对壳环和壳贝冢地点现存和新的放射性碳测年进行建模，以与树木年代学序列进行比较，该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识产权进行评估来支持。优点和更广泛的影响审查标准。
