Climatic "pause" during Termination II identified in shallow and intermediate waters off the Iberian margin
International audience The sequence of Termination II, from the end of marine isotopic stage 6 (MIS 6) to MIS 5e, is observed through an isotopic study (δ18O) of planktic and benthic foraminifera in core MD99-2331 (42°09′N; 09°41′W), collected in the North Atlantic, on the Iberian margin. First, to...
