Stable isotope record and calcium carbonate concentrations of Late Pliocene sediments of the North Atlantic ...
High-resolution records of delta18O, delta13O, and percent CaCO3 from the late Pliocene North Atlantic (Deep Sea Drilling Project sites 607 and 609) are presented and oxygen isotope stages are formalized back to stage 116 at 2.73 Ma. From 2.8 to 1.6 Ma, the interval studied, variations in these reco...
