Reconstructing Late Holocene Climate Change in the Central Canadian High Arctic Using Laminated Sediments

题目：利用层状沉积物重建加拿大中部高北极地区晚全新世气候变化。该奖项支持利用层状湖泊和海洋沉积物对加拿大中部北极群岛地区晚全新世气候变化的研究。此外，通过对几个含阀盆地的现代气候学、水文和沉积学过程的研究，研究人员将试图了解将阀沉积记录与气候系统联系起来的一些复杂性，从而为解释沉积物中的古气候记录提供准确的手段。这些研究的主要重点是评估近千年来气候变化的影响和意义，特别是中世纪暖期和小冰期的影响和区域变率。该地区的不同沉积物记录将扩展仪器记录（1950年以后）的详细信息，并提供与其他来源的古气候信息相匹配的空间分辨率。

Abstract ATM-9809963 Ratelle, Michael J. Bates College Title: Reconstructing Late Holocene Climate Change in the Central Canadian High Arctic Using Laminated Sediments This award supports a study of late Holocene climate change in the central Canadian arctic archipelago using laminated lacustrine and marine sediments. In addition, through studies of modern climatological, hydrological, and sedimentological processes in several basins containing varves, researchers will attempt to understand some of the complexities linking the varved sediment record to the climate system, thus providing an accurate means for interpreting the paleoclimate record in the sediments. The major focus of these studies is to evaluate the impacts and significance of climate changes of the last millennia, particularly the impacts and regional variability of the Medieval Warm period and Little Ice Age. Varved sediment records from the region will extend the detailed information from instrumental records (post-1950) and provide a spatial resolution to accompany paleoclimatic information from other source.
