This project deals with the paleoclimate of the region that extends from the Eastern Canadian Arctic eastward to Greenland and Iceland. This is an area that is critical for the integration of present and past records of climatic change, especially within the context of the Arctic System Science Program (ARCSS research agenda. The main objectives of the research will be to concentrate on the evaluation, synthesis and interpetation of: i) instrumental records; ii) historical data sources from Iceland; iii) the GISP2 isotopic time-series; iv) high-resolution marine series near East Greenland; and v) annually laminated lake records from Southeast Baffin Island and Iceland. The project will include an analysis of climate impact in Iceland in recent centuries. Thus, although focussing on paleoclimatic reconstruction and interpretation, the research also has a human dimensions perspective and links directly with the needs of the new ARCSS Paleo initiative (Archeology and Ethnohistory) regarding the documentation and understanding of the role of climatic variations in the Norse expansion throughout the North Atlantic, and human responses to the so- called "Medieval Warm Period" and Little Ice Age". In conlcusion, the overall goal is directed towards improving the understanding of annual to century timescale fluctuations of climate in this region, as well as the influences of such changes on Humankind.

该项目涉及从加拿大北极东部向东延伸到格陵兰岛和冰岛的地区的古气候。 这是一个对整合气候变化的现在和过去记录至关重要的领域，特别是在北极系统科学计划（ARCSS研究议程）的背景下。 研究的主要目标是集中评价、综合和解释：一）仪器记录;二）冰岛的历史数据来源;三）GISP 2同位素时间序列;四）东格陵兰附近的高分辨率海洋序列;五）巴芬岛东南部和冰岛的年度分层湖泊记录。 该项目将包括对冰岛近几个世纪来气候影响的分析。 因此，虽然侧重于古气候重建和解释，研究也有一个人的尺寸的角度来看，并直接与新的ARCSS古倡议的需要（考古学和民族史）关于记录和了解气候变化在整个北大西洋北欧扩张中的作用，以及人类对所谓的“中世纪温暖期”和“小冰河期”的反应。 总的目标是提高对该地区气候年至世纪尺度波动的认识，以及这种变化对人类的影响。
