AbstractThe seabed of Frobisher Bay exhibits a complex topography reflecting the predominance of exposed bedrock. Superimposed on the bedrock are landforms created by the flow of grounded ice during the last glacial period. As this ice retreated, glaciomarine sediment was deposited in bedrock troughs and subsequently overlaid by postglacial mud. Areas of the seafloor were impacted by icebergs at the retreating ice margin and by the modern iceberg flux. Slope failures in the seabed sediments are numerous.
