Abstract:We collected a 118-cm-long and well-preserved sediment profile, which contains a large number of mollusk shell fragments - predominantly Mya truncata, from a paleo-notch on Ny-Ålesund, Svalbard, high Arctic. AMS14C dating and stable oxygen and carbon isotope analyses were performed on the shell fragments. The average reservoir-corrected radiocarbon age is ~9,400 yr B.P., indicating the mortality time of fossil mollusk in the paleo-notch sediments. The aragonite isotopic temperature equation was calibrated for Ny-Ålesund based on the δ18O profiles of modern mollusks. The calculated paleotemperature was between – 0.52 and + 4.78 ºC, warmer than today by about 1 ºC; and this is consistent with the reconstructed Sea Surface Temperature (SST) in west Svalbard. As inferred from reduced insolation, weakened thermohaline circulation (THC), and abrupt decreased SST, there was an abrupt cooling event at ~9,400 yr B.P.; and this cooling event very likely caused the mortality of the fossil mollusks. While great amount of attention has been paid towards global warming in today\\\ | |||
