Glacigenic debris-flows observed in 3D seismic high-resolution seafloor imagery, Faroe–Shetland Channel, NE Atlantic

Glacigenic debris-flows represent successive mass-flow deposits that build out a prograding wedge of sediment beyond the grounding zone of an ice sheet (e.g. Laberg & Vorren 1995; King et al. 1998). A prograding sedimentary depocentre extending from the outer shelf to the upper slope has been ob...

Description
Summary:Glacigenic debris-flows represent successive mass-flow deposits that build out a prograding wedge of sediment beyond the grounding zone of an ice sheet (e.g. Laberg & Vorren 1995; King et al. 1998). A prograding sedimentary depocentre extending from the outer shelf to the upper slope has been observed in geophysical datasets from the West Shetland margin of the Faroe–Shetland Channel, NW of the UK in the NE Atlantic. Overlapping, glacigenic debris-flows comprise the Rona and Foula wedges and provide insight into the extent and stability of the northern sector of the British Ice Sheet during the last full-glacial period (Stoker & Varming 2011).
