Terrigenous components in the core P31 from the Chukchi Plateau, western Arctic Ocean, have been investigated to reconstruct source regions and related climate changes. Together with AMS14C dating, the stratigraphy of the core was established by a combination of variations of lithological features, color cycles, XRF scanned elements content, foraminifera abundance, Ice Rafted Detritus (IRD, >250 μm and >154 μm) events and grain size components. The Core P31 extends back to the Marine Isotope Stage (MIS) 3.A. The overall picture of the western Arctic Ocean shows high sedimentation rates in the ice edge, and low sedimentation rates in areas with permanent sea ice cover. High sedimentation rates occur in areas of shallow water depth, and close to the terrigenous source regions, and low sedimentation rates in the high latitude area of Mendeleev-alpha ridge and Canada Basin area.
