Extended Data Fig. 5: The morphology of corrugation ridges within and beyond seafloor incisions.
From: Rapid, buoyancy-driven ice-sheet retreat of hundreds of metres per day

a, Corrugation ridge amplitude and spacing, coloured by whether they are found within or beyond seafloor incisions (Methods). b, Corrugation ridge spacing and seafloor gradient, coloured by whether they are found within or beyond seafloor incisions. c, Map showing the distribution of corrugation ridges within and beyond seafloor incisions. Detailed bathymetric data: ©Kartverket. Background bathymetry is Olex single-beam echo-sounder data (grid cell size 50 m)45. Shelf break, seaward limit of exposed bedrock and GZW locations are from Ottesen et al.22. Geographical boundaries from European Environment Agency46. Map produced using ESRI ArcMap.
