description |
The data comprise meters composite depth (mcd) versus component declination, inclination and maximum angular deviation (MAD) values for natural remanent magnetization (NRM) from Integrated Ocean Drilling Program (IODP) Site U1306 drilled on the crest of the Eirik Drift (SW Greenland) in 2272 m water depth. The component magnetizations were determined from stepwise alternating field demagnetization of NRM and measured on a pass-through u-channel magnetometer (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. 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.
