Summary

During the last ice age, the Barents Sea ice sheet began to grow 22 kyr ago, only 8 kyr before it began to disintegrate. Such rapid growth of a large ice sheet requires significant amounts of moisture. The authors present data from deep-sea sediment cores from the Fram Strait, which suggest that relatively warm water from the North Atlantic Ocean was advected into the region, in two short-term events (27-22.5 and 19.5-14.5 kyr ago). They suggest that the resulting seasonally ice-free waters were an important regional moisture source for the Barents Sea ice sheet.
