TRI scan area. a TRI amplitude image overlain on a Landsat-8 image (both acquired on 13 June 2016). Black areas are in radar line-of-sight (LOS) shadow. Yellow line outlines the area within 10 km of the radar, shown in Fig. 2a. Dashed red line indicates glacier front location. Cyan arrows mark the elevation step-change in the mélange. Upper right inset shows location of Jakobshavn Isbræ in Greenland. b Dashed blue box outlines the area presented in a. Red lines show calving front positions in different years, courtesy of NASA Earth Observatory. Both a and b are in polar stereographic projection (EPSG: 3413)
