| Summary: | The sites occupied during Integrated Ocean Drilling Program Expedition 303/306 were chosen to recover late Miocene to Quaternary records of North Atlantic environmental variability at elevated mean sedimentation rates from locations appropriate for oxygen isotope (δ18O) and relative paleointensity (RPI) stratigraphies. The overall objective is to correlate these climate/paleoceanographic records to two (ostensibly) independent global stratigraphic sig-nals (δ18O and RPI), thereby enhancing stratigraphic resolution. One site at Orphan Knoll (Site U1302/U1303) provided a proxi-mal record of Laurentide Ice Sheet instability for the Brunhes Chron. Three sites from the Eirik Drift (Sites U1305, U1306, and U1307) provided records of the strength and location of the West-ern Boundary Undercurrents well as monitors of Greenland Ice Sheet instability back into the Pliocene.
