Title: Abstract: Comparison of Late Holocene and Pleistocene sedimentologic and oceanographic records in the Amundsen Gulf, Northwest Territories, Canada
Abstract: Analysis of sediments of two box cores from Canadian Arctic Shelf Exchange Study (CASES), stations 403B (59 m) and 415B (56 m) located in the Amundsen Gulf, allow the determination of the sedimentologic and oceanographic records from the area. Arctic benthic foraminiferal assemblages of the Late Holocene (403B) and Pleistocene (415B) show differences in foraminifers between an environment of high sedimentation (core 403B) and an area of low sedimentation (415B) with evidence of erosion related to glaciation. This contrast will provide insight into glacial records and Arctic productivity. Potential impacts on the Arctic ecosystem need to be explored, since the Arctic is most vulnerable to changes in climate and specifi cally changes in sea ice cover. This study will contribute to the assessment of the factors that presently infl uence sea ice cover which are important in the understanding of the impacts on coastal shelf region of the Arctic.
