Decadal climate sensitivity of contouritic sedimentation in a dynamically coupled ice-ocean-sediment model of the North Atlantic

Ocean sediment drifts contain important information about past bottom currents but a direct link between the study of sedimentary archives and ocean dynamics is not always possible. To close this gap for North Atlantic, we set up new coupled Ice-Ocean-Sediment Model N. Atlantic - Arctic region. In order to evaluate potential model, conducted decadal sensitivity experiments. our model contouritic sedimentation shows significant towards climate variability most contourite drift locations in domain. We observe general decrease rates during warm conditions with decreasing atmospheric oceanic gradients an extensive increase cold respective increased gradients. can relate these results changes dominant circulation supplying deep water masses sites under different conditions.
