Abstract
Cenozoic biostratigraphic, cosmogenic isotope, magnetostratigraphic, and cyclostratigraphic data derived
from Integrated Ocean Drilling Program Expedition 302, the Arctic Coring Expedition (ACEX), are merged into
a coherent age model. This age model has low resolution because of poor core recovery, limited availability of
biostratigraphic information, and the complex nature of the magnetostratigraphic record. One 2.2 Ma long hiatus
occurs in the late Miocene; another spans 26 Ma (18.2–44.4 Ma). The average sedimentation rate in the
recovered Cenozoic sediments is about 15 m/Ma. Core-seismic correlation links the ACEX sediments to the
reflection seismic stratigraphy of line AWI-91090, on which the ACEX sites were drilled. This
seismostratigraphy can be correlated over wide geographic areas in the central Arctic Ocean, implying that
the ACEX age model can be extended well beyond the drill sites.
