“…However, a large number of ice streams were uncovered in the early 2000s (e.g. Clark and Stokes, 2001;Shaw, 2003), such that by 2004, a new map of ice streams in the LIS depicted a total of 49 ice streams, 34 of which had good evidence, with the remainder more uncertain (Winsborrow et al, 2004). Much of the evidence was based on the terrestrial glacial geological record, but the recognition of discrete layers of ice rafted debris (IRD) in North Atlantic sediment cores (Heinrich, 1988) had also begun to implicate episodic ice streaming, particularly in Hudson Strait, as being primarily responsible for their deposition (Bond et al, 1992;Andrews and Tedesco, 1992;MacAyeal, 1993;Marshall and Clark, 1997a, b;Andrews, 1998).…”

“…They identified four distinct ridges at the lateral margin of the M'Clintock Channel Ice Stream (cf. Hodgson, 1994;Clark and Stokes, 2001). The southernmost moraine is shown in Figure 2 and represents a 22 km long sinuous ridge of till.…”

“…Technological advances in geophysical exploration of active sub-ice stream environments will also go a long way towards solving this particular conundrum. The ice stream lineations indicate flow to the north on the right of the image, whereas the area to the west of the moraine is outside of the margin and show no evidence of stream-lining (see Hodgson, 1994 andStokes, 2001 for discussion of the reconstructed glacial history). : Erosion/deposition rates and downstream velocities for different basal properties.…”

“…top right of the image). See (Stokes and Clark, 2002) and can be seen here bordering a south to north flowing ice stream (the M'Clintock Channel Ice Stream: Hodgson, 1994;Clark and Stokes, 2001), recorded by mega-scale glacial lineations. The long esker that runs east to west across the centre of the image dissects the moraine and the age control from Hodgson (1994) indicates that slow-flowing ice must have been present adjacent to the ice stream (i.e.…”
