Submarine Debris Flows on a Glacially-Influenced Basin Plain, Faeroe-Shetland Channel

Abstract

The Faeroe-Shetland Channel is a narrow deep-water basin separating the West Shetland and Faeroe shelves (Fig. 1), which acted as a trap for glacigenic sediment during the mid- to late Pleistocene [Stoker et al, 1991]. At the south-west end of the basin, debris flows are preserved within the basinal succession; acoustic profiling with a 6 kV deep-tow boomer (Table 1) has provided extremely well-imaged examples of their seismic facies, depositional features, and stratal geometries and relationships (Fig. 2).
