The final version is available from the Geological Society of London via https://doi.org/doi.org/10.1144/M46.96Streamlined glacial landforms, produced by deformation of soft sediments at glacier beds (Dowdeswell et al. 2004; Ó Cofaigh et al. 2005; King et al. 2009), provide clear evidence of the direction of ice-flow at the time of their formation (e.g. Ottesen et al., 2005; Livingstone et al. 2012). Where sets of streamlined landforms are present at or close to the seafloor, swath-bathymetric imagery enables the reconstruction of multiple phases of ice-flow (e.g. Greenwood et al. 2012). In many cases, however, key morphological evidence is buried on palaeo-shelves within the Quaternary glacial sedimentary record (Fig. 1c-d), and can only be analysed by tracing these buried horizons in 3D-seismic datasets (Dowdeswell et al. 2007)
