Comparison of the East Greenland iceberg dominated and Alaska glacial meltwater dominated environments indicates few major differences between sediments deposited in these two settings. Despite their proximity to each other, each fjord is distinguished by a distinct sedimentological signature: Kangerlussuaq Fjord has low total organic carbon contact, Miki Fjord has high mass magnetic susceptibility, and Nansen Fjord has high amounts of ice-rafted debris.
Alternating units of diamicton and fine-grained mud in Nansen Fjord are deposited by sediment rain-out from icebergs particle size is governed by the oceanographic conditions in the fjord at the time of deposition. Miki Fjord records rain-out of fine-grained muds from a river plume emanating from a proglacial delta at the fjord head. The sediments in Kangerlussuaq Fjord are predominately fine-grained muds deposited by rain-out from icebergs and glacier meltwater, with sediment gravity flows acting as secondary agents of deposition. Three major lithofacies, diamicton, fine-grained mud, and sand, are deposited by two processes, sediment rain-out and sediment gravity flows.
Sediment cores from three East Greenland fjords contain sediment lithofacies and depositional processes in an iceberg dominated glacial marine setting.
