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东部北极向东延伸到格陵兰岛和冰岛的古气候。这是一个整合现在和过去气候变化记录的关键领域，特别是在北极系统科学计划（ARCSS）研究议程的背景下。研究的主要目标将集中在以下方面的评价、综合和解释：1)仪器记录；ii)冰岛的历史数据来源；iii) GISP2同位素时间序列；东格陵兰附近高分辨率海洋序列；巴芬岛东南部和冰岛的年际湖层积记录。该项目将包括对冰岛近几个世纪气候影响的分析。因此，尽管侧重于古气候的重建和解释，该研究也有人类维度的视角，并与新的ARCSS古计划（考古学和民族史）的需求直接相关，该计划涉及记录和理解气候变化在北欧人整个北大西洋扩张中的作用，以及人类对所谓的“中世纪温暖期”和“小冰河期”的反应。最后，总的目标是提高对该区域气候年至世纪时间尺度波动的了解，以及这种变化对人类的影响。
