  • The Arctic Ocean was covered by a shelf ice and filled with freshwater

    marine deposits, the scientists could demonstrate that the Arctic Ocean as well as the Nordic Seas did not contain sea-salt in at least two glacial periods. Instead, these oceans were filled with large amounts [...] amounts of freshwater under a thick ice sheet. This water could then be released into the North Atlantic in very short periods of time. Such sudden freshwater inputs could explain rapid climate oscillations
