Results from mapping with a modern MBES system deployed from the Swedish icebreaker Oden in Pine Island Bay, West Antarctica. Multibeam acquisition system Kongsberg EM 122. Frequency 12 kHz. Grid-cell size 15 m. (a) Map showing the location of the multibeam imagery in (b) (from IBCAO v. 3.0). (b) Detailed map of the ship tracks and core sites (black dots) acquired during the Oden survey in Pine Island Bay. (c, e) Detailed multibeam images of the seafloor features referred to as corrugation ridges (Jakobsson et al. 2011). The spatial dimensions of these regular corrugation ridges were analysed statistically and the formation mechanism was linked to tidal motion of icebergs from a disintegrated ice shelf–ice stream system. (d) Bathymetric profile between X and X′ in (c) extracted from the MBES data. VE×121.
