Astronomical age models for Pleistocene drift sediments from the western North Atlantic (ODP Sites 1055^1063)

Ten ODP sites drilled in a depth transect (2164^4775 m water depth) during Leg 172 recovered high-deposition rate (s 20 cm/kyr) sedimentary sections from sediment drifts in the western North Atlantic. For each site an age model covering the past 0.8^0.9 Ma has been developed. The time scales have a...
