Short summary

Arctic Pleistocene benthic foraminifers show distinct temporal and spatial distribution patterns in the Arctic Ocean. We refine previously applied calcareous benthic foraminiferal bioevents and correlated them with lithology changes and independent stratigraphic markers. Benthic foraminifera colonized the Arctic Ocean via advection of Atlantic water and ecological requirements must have been met locally for the species to settle. Yet, bioevents also reflect significant diagenetic loss.
