As shown in numerous studies of sediment cores from the Amerasian Basin, the lithostratigraphy of CLARK et al. (1980) seems to be a very useful tool for core correlation and for getting a relative stratigraphie framework in large parts of the Amerasian Basin. Because from Clark's cores collected from Ice Island T3 in the Amerasian Basin between 1952 and 1974, neither untouched archive and fresh (unaltered) sediment material nor stateof-the-art paleo-records used in modern paleoceanography (e.g., stable isotopes, geochemical proxies, MSCL logging, and XRF scanning), are available, a precise correlation to more recently recovered sediment cores from the Amerasian and Eurasian basins is difficult or even not possible. Thus, sediment core PS72/392-5 was recovered in the Nautilus Basin, a small sub-basin of the Canada Basin in the vicinity of the Mendeleev Ridge, during RV ., stern" ARK-XXIII/3 expedition in 2008 at the same location as Clark's key core FL-224. In core PS72/392-5, all the thirteen standard lithostratigraphic (SL) units A through M developed by CLARK et al. (1980), including the most prominent pink-white/white layers PW1, PW2 and W3, could clearly be identified. Future studies of this unique core material will allow to use up-to-date tools and methods in paleoceanography needed for a precise core correlation, a development of a more accurate age model, and a more detailed reconstruction of the circum-Arctic environmental history. Based on a still preliminary age model, the more sandy intervals of SL units L, J, H, F, and C are correlated with periods of a maximum ice-sheet extent and its subsequent disintegration (glacial/deglacial phases) during glacial Marine Isotope Stages (MIS) 6, 8, 10, 12, and 16. Except MIS 6, these intervals are characterized by increased dolomite contents indicating ice-rafted debris (IRD) input from the Laurentide Ice Sheet (LIS). The dolomite-rich pink-white layers PW1 and PW2 probably represent short-lived events of IRD input related to a collapse of the LIS during MIS 8 and MIS 5d. During MIS 16 - for the first time - the LIS may have been large enough to reach the shelf break and release major amounts of (dolomite-laden) icebergs into the ocean when the disintegration of the LIS started. This still speculative hypothesis, however, has to be approved by further more detailed studies.
