a Mapped HR3D seismic surface displaying two flowsets of multi-keeled iceberg ploughmarks cross-cut by smaller single-keeled ploughmarks. b–e Horizontal timeslices of multi-keeled iceberg ploughmarks buried at different depths in the HR3D seismic data. Note how the multi-keeled iceberg ploughmarks in (d) overprint the megascale glacial lineations (MSGLs), interpreted by Graham et al. 52 to be of Late Weichselian (last glacial) age. Ploughmark locations are displayed in Fig. 6.
