NOAA/WDS Paleoclimatology - South Sawtooth Lake, Ellesmere Island 2,700 Year Sediment Magnetic Data

This paper synthesizes data collected to document the modern limnological and sedimentary processes in South Sawtooth Lake located on northern Ellesmere Island, Nunavut, Canada. Field observations show that the finely laminated sediments deposited in the distal basin are formed by the settling of overflows and interflows, and in rare occasions, by non-erosive hyperconcentrated density flows. Thin-sections of these sediments allowed for the classification of the sedimentary fabrics into six facies, each representing different limnological processes. The sediments in this distal basin are considered to be continuous and annually laminated (varved) based on radioisotope analyses, and both limnological and sedimentological evidence.本归档古气候学（Paleoclimatology）研究数据集可从美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）下属的国家环境信息中心（National Centers for Environmental Information, NCEI）获取，该数据集隶属于古气候学世界数据服务（World Data Service for Paleoclimatology, WDS）。其关联的NCEI研究类型为湖泊类。数据集涵盖古湖沼学（Paleolimnology）相关参数，研究地理位置位于加拿大努纳武特（Nunavut）地区。时间覆盖范围为距今（Before Present, BP）2650年至-50年。如需了解参数与研究地点的详细信息，请查阅相关元数据。使用本数据集时，请引用该研究。
