The goal of this project is to understand changes and interactions among arctic system components (climate, people, terrestrial and marine ecosystems, sea-ice and glacier extent) in Peary Land, north of the Greenland Ice Sheet, where people with stone tool technology managed to survive for prolonged periods during the past ~4500 years. We propose to produce multi-proxy high resolution, quantitative records of climate and vegetation from lake sediments, and to examine the persistence of polynyas along the coast, where marine mammals congregate, using high-resolution model simulations. Paleoenvironmental records will be coupled with new archaeological data generated from a field mapping campaign to comprehensively survey sites and a program to radiocarbon date existing archeological materials to improve the chronology of human activities in the region. We will explore the extent to which periods of settlement and times of abandonment were related to climatic fluctuations that affected the availability of terrestrial and marine resources, which were essential for survival in this very remote region. The target region is considered as a model to consider the nexus of climate change, resource availability, and human response in a paleo context-- issues that still resonate today throughout the Arctic.

该项目的目标是了解北极系统组成部分（气候，人类，陆地和海洋生态系统，海冰和冰川范围）之间的变化和相互作用，位于格陵兰冰盖北部的Peary Land，在过去的4500年中，人们使用石器技术设法长时间生存。我们建议产生多代理高分辨率，定量记录的气候和植被湖泊沉积物，并检查的持久性的polynyas沿着海岸，海洋哺乳动物聚集，使用高分辨率模型模拟。古环境记录将与新的考古数据相结合，这些数据是从实地测绘活动中产生的，以全面调查遗址，并计划对现有的考古材料进行放射性碳年代测定，以改善该地区人类活动的年表。我们将探讨定居时期和遗弃时期与气候波动的关系，气候波动影响了陆地和海洋资源的可用性，而陆地和海洋资源对这一非常偏远地区的生存至关重要。目标区域被视为一个模型，以考虑气候变化，资源可用性和人类在古环境中的反应-今天仍然在整个北极引起共鸣的问题。
