Paleomagnetism from IODP Site 303-U1307

We present new sedimentological and environmental magnetic records spanning ~3.2–2.2 Ma, during the intensification of Northern Hemisphere glaciation, from North Atlantic Integrated Ocean Drilling Program Site U1307 on Eirik Drift. Underpinned by a high-fidelity relative paleointensity-based age model, these datasets provide a high-resolution picture of ice-rafting from the proximal southern Greenland Ice Sheet as well as environmental magnetic variability throughout the study interval, with implications for sediment source and relative strength of bottom-currents
