IODP Expeditions 303 and 306 Monitor Miocene-
Quaternary Climate in the North Atlantic

Introduction
The IODP Expeditions 303 and 306 drilling sites were
chosen for two reasons: (1) to capture Miocene-Quaternary
millennial-scale climate variability in sensitive regions at the
mouth of the Labrador Sea and in the North Atlantic ice-
rafted debris (IRD) belt (Ruddiman et al., 1977), and (2) to
provide the sedimentary and paleomagnetic attributes,
including adequate sedimentation rates, for constructing
high-resolution isotopic and magnetic stratigraphies.
High accumulation rates, reaching 20 cm ky-1, permit the
study of millennial-scale variations in climate and in the
Earth's magnetic field over the past several million years,
when the amplitude and frequency of climate variability
