“…These amplitudes are similar to those observed for well-preserved lineations on Antarctic shelves [Dowdeswell et al, 2004]. Streamlined subglacial bedforms, often referred to as 'mega-scale glacial lineations' [Clark, 1993[Clark, , 1994, have been used to infer the former presence of fast-flowing ice streams on continental shelves in both the Arctic and Antarctic [e.g., Shipp et al, 1999Shipp et al, , 2002Canals et al, 2000;Wellner et al, 2001;Ó Cofaigh et al, 2002;Ottesen et al, 2002Ottesen et al, , 2005.…”
