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.

摘要ATM-9809963 Ratelle，Michael J. Bates学院标题：使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 该奖项支持在加拿大北极群岛中部使用层状湖泊和海洋沉积物的晚全新世气候变化的研究。 此外，通过对几个含有纹层的盆地的现代气候学、水文学和沉积学过程的研究，研究人员将试图了解纹层沉积物记录与气候系统之间的一些复杂性，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上千年气候变化的影响和意义，特别是中世纪温暖期和小冰期的影响和区域变化。 该地区的沉积物记录将扩展仪器记录（1950年后）的详细信息，并提供空间分辨率，以伴随其他来源的古气候信息。
