Fig. 2: Larsen C study area in 2008/09.
From: Seawater softening of suture zones inhibits fracture propagation in Antarctic ice shelves
ASTER-GDEM [http://nsidc.org/data/docs/agdc/nsidc0516-cook/] derived DEM is superimposed on a 2008 MODIS image [https://earthdata.nasa.gov/data/near-real-time-data/rapid-response]. Inset shows location of Larsen C Ice Shelf on the Antarctic Peninsula, with Joerg Peninsula (JP), Trail Inlet (TI), Solberg Inlet (SI) and Table Nunatak (TN) labelled. The magenta lines trace the outlines of the JP suture zone, the first ~50 km of which is its formation area that is laterally compressed (white arrows) as TI- and SI-derived meteoric ice-shelf units converge. The filled blue circles mark the locations of our seismic reflection profiles at JP-Seis and SI-Seis, and the two red dotted arrows show our ground-penetrating radar (GPR) profiles across and along flow. The solid black arrow indicates the unnamed glacier on the JP that calves glacier-derived blocks into the JP suture zone, and the light grey shaded area indicates the large tabular iceberg (A68) that calved in July 201732,33.
