Extended Data Fig. 8: Ice geometry and dynamics immediately downstream of the collapse basin.
From: Outburst of a subglacial flood from the surface of the Greenland Ice Sheet
Ice geometry and dynamics along a profile immediately downstream of the collapse basin, encompassing the region of surface fractures. a. the location of the profile, b. surface and bed elevations from BedMachine version 346, c. ice thickness and associated uncertainty (grey shading) from BedMachine version 346, d. ice velocity, and e. longitudinal strain rate. In panels b-e the green shading indicates the region where ice fracturing is observed at the surface. In panel e the blue and red shading indicate compressional and extensional flow, respectively, the dashed line denotes the longitudinal strain rate, and the solid line is a linear fit to the longitudinal strain rate, showing the large-scale trend across the region of interest.
