Abstract: The cores were collected using a small gravity corer aboard the MV Nuliajuk in September 2014, and a piston corer aboard the CCGS Amundsen during October of 2014 and 2015. Initial data included records of sample location and core length. Laboratory work has produced lithological logs, photography and x-radiography, grains size analysis, and radiocarbon dates from the cores sampled in 2014. For the 2015 cores, lithological logs, photography and x-radiography have also been obtained, with grains size analysis and radiocarbon dating in progress. The sediment cores were collected to better constrain the submergence history of the east coast of Baffin Island. Through analysis of the stratigraphic record preserved in these cores and the dating of organic material contained within it, it is possible to determine when the sampled sedimentary features would have stopped developing due to submergence. The dates obtained from these cores are intended to complement dates retrieved from elevated shoreline features in order to provide the emergence history of the region.
