Multibeam swath bathymetry data sets collected over the past two decades have been compiled to identify palaeo-ice stream pathways in the easternmost Amundsen Sea Embayment. We mapped ~ 3000 glacial landforms to reconstruct ice flow in the ~ 250-km-long cross-shelf Abbot Trough. This bathymetric fea...
