epoch, particularly during the Holocene climatic optimum. The increased flow from the nearby East Greenland Current was associated with increased glacial iceberg calving from the large Jakobshavn Isbrae glacial outlet within the western Greenland Ice Sheet, causing rapid melting and destabilization events. Following the Neoglaciation, the Jakobshavn outlet formed a floating
