This is a project that is jointly funded by the National Science Foundation’s Directorate of Geosciences (NSF/GEO) and the National Environment Research Council (UKRI/NERC) of the United Kingdom (UK) via the NSF/GEO-NERC Lead Agency Agreement. This Agreement allows a single joint US/UK proposal to be submitted and peer-reviewed by the Agency whose investigator has the largest proportion of the budget. Upon successful joint determination of an award, each Agency funds the proportion of the budget and the investigators associated with its own investigators and component of the work.Arctic communities have a long history of endurance in extreme climates. How people responded to environmental change in the past is of direct relevance today and will offer those who live in the North a window into a time when ancient people found ways to endure in the most difficult circumstances. The research will document how periods of human settlement and abandonment in northern Greenland were related to climate fluctuations over the past 4500 years. In this remote region, climate change played a critical role in the survival of people by affecting vegetation and the abundance of grazing animals, as well as the presence of marine mammals on the coast. When climate was favorable, resources were abundant and the vulnerability of humans to environmental change was low. During times of less favorable climate, resources became more limited and sensitivity to fluctuations in climate increased. When conditions became sufficiently inhospitable to humans, exceeding the ability of people to adapt, they left the area for more favorable locations. The project will assess the conditions under which early people were able to adapt and survive, as well as conditions that may have led them to abandon the region. The project will examine interactions among physical, biological, and human systems in an extreme, High Arctic environment. The project will produce high resolution, quantitative records of climate and vegetation change from lake sediments, obtained from locations adjacent to prehistoric settlements. Measurements of the inorganic content, lipid biomarkers, compound specific stable isotopes, pollen and spores, chironomids, diatoms, and sedimentary ancient DNA will shed light on paleoclimate patterns in the region. An archaeological survey using fixed-wing drones will be conducted to inventory archaeological sites in the region, and the project will model past coastal sea-ice extent under different climatic conditions. Several students and early career researchers will be trained throughout the project, and outreach to communities in Greenland as well as students in the United States will communicate research outcomes to a wide audience.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.

这是一个由国家科学基金会地球科学局（NSF/GEO）和英国国家环境研究委员会（UK）（UK）（UK）共同资助的项目。该协议允许该机构提交和同行评审的一项联合提案，其调查员的预算比例最大。成功确定奖励后，每个机构都为预算的比例以及与其自己的调查人员和工作组成部分相关的调查人员提供了资金。在极端气候中，阿克社区的耐力历史悠久。人们如何应对过去的环境变化是直接相关的，它将为北部生活的人提供一个窗户，进入古老的人们在最困难的情况下找到忍受的方式。该研究将记录格陵兰北部的人类定居和遗弃时期与过去4500年中的气候波动有关。在这个偏远地区，气候变化通过影响蔬菜和放牧动物的抽象以及海岸的海洋哺乳动物的存在，在人们的生存中起着至关重要的作用。当气候有利时，资源丰富，人类对环境变化的脆弱性很低。在气候不佳的时期，资源变得更加有限，对气候波动的敏感性增加。当条件变得足够多的人对人类的荒凉，超过人们适应的能力时，他们离开该地区前往更有利的位置。该项目将评估早期人们能够适应和生存的条件，以及可能导致他们放弃该地区的条件。该项目将在极端高的北极环境中检查物理，生物和人类系统之间的相互作用。该项目将产生高分辨率，气候和植被从湖泊沉积物的变化的定量记录，从史前定居点附近获得的湖泊沉积物。无机含量，脂质生物标志物，复合特定稳定同位素，花粉和孢子，哲学，硅藻，硅藻和沉积古DNA的测量将使该地区的古气候模式揭示。使用固定翼无人机的考古调查将用于该地区的库存存档地点，该项目将在不同的气候条件下对过去的沿海海冰范围进行建模。几名学生和早期的职业研究人员将在整个项目中接受培训，并向格陵兰的社区以及美国的学生进行宣传，将向广泛的受众传达研究成果。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响来评估的珍贵的支​​持。
