a, Bathymetric map of part of the upper Congo Canyon derived from data collected in 2005. b, Bathymetric map of the same area from 2019. A canyon-flank landslide that has dammed the canyon is shown. The landslide-dam has resulted in the trapping of sediment leading to infilling up-canyon of the landslide-dam. c, Difference map of the 2005 data and the 2019 bathymetry resampled to 25 m showing the canyon-flank landslide, the landslide-dam and the sedimentary infill. This is overlain on a hillshade map of the 2019 bathymetric data. It allows the patterns of erosion and deposition to be characterized.
