Comment:
Dating method:
(a) radiocarbon + correlation with nearby MD98-2176
(b) AMS 14C on ME-43JC; ODP1242 is correlated with ME43-JC through comparison of d18O. Mg/Ca and sediment density data; SST of both sequences are together
(c) The chronology was obtained by attributing ages to the key stratigrahic events identified in other cores from the North Atlantic with detailed radiocarbon chronologies.
