Abstract
Analyses of physical properties, lithofacies and biofacies indicate that there is a very sharp break in the record at around 12.4 cal ka, which is interpreted as a change from relatively ice-distal conditions to one characterized by a dramatic increase in cold, ice-proximal formaniniferal benthic species. At the same time, there was an extremely abrupt increase in detrital carbonate, most of which is dolomite. This abrupt event signals an increase in the transport of detrital carbonate derived from icebergs and/or meltwater from sources further north in Baffin Bay, or immediately to the south from Cumberland Strait.
