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.

该项目研究从加拿大东部北极向东延伸至格陵兰岛和冰岛的地区的古气候。 这是一个对于整合现在和过去的气候变化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。该研究的主要目标将集中于评估、综合和解释：i）仪器记录； ii) 来自冰岛的历史数据源； iii) GISP2 同位素时间序列； iv) 东格陵兰附近的高分辨率海洋系列； v) 每年对东南巴芬岛和冰岛的湖泊记录进行分层。 该项目将包括对近几个世纪冰岛气候影响的分析。 因此，虽然侧重于古气候重建和解释，但该研究也具有人类维度的视角，并与新的 ARCSS 古倡议（考古学和民族史）的需求直接相关，涉及记录和理解气候变化在整个北大西洋的北欧扩张中的作用，以及人类对所谓“中世纪温暖期”和“小冰河期”的反应。总而言之， 总体目标是提高对该地区气候年至百年时间尺度波动以及此类变化对人类影响的了解。
