Description
Summary:The data comprise meters composite depth (mcd) versus oxygen isotope measurements on Neogloboquadrina pachyderma from Integrated Ocean Drilling Program (IODP) Site U130 using a Fisons Optima mass spectrometer at Rutgers University (see Channell et al., 2014). Planktic oxygen isotope (δ18O) and relative paleointensity (RPI) data are used in tandem to generate an age model for the last 1 Myr from Integrated Ocean Drilling Program (IODP) Site U1306 drilled on the crest of the Eirik Drift (SW Greenland) in 2272 m water depth. For the 1-1.5 Ma interval, the age model is based on RPI alone due to insufficient foraminifera for isotope analyses. Utilizing RPI and δ18O in tandem allows recognition of low-δ18O "events" prior to glacial Terminations I, III, IV, V, VII, VIII, IX and X, that are independently supported by radiocarbon dates through the last deglaciation, and are attributed to local or regional surface-water effects. At Site U1306, Quaternary sedimentation rates (mean ~15 cm/kyr) are elevated during peak ...
