Running the models: GSM: A full description of the GSM with the associated code archive and complete documentation will soon be submitted and then linked here. We are happy to provide the code upon individual request. The input files used specifically for "Numerical issues in modeling ice sheet instabilities such as binge-purge type cyclic ice stream surging" are described here. The GSM uses bed masks to set the sediment cover of each grid cell. The bed masks for all four resolutions (25 km, 12.5 km, 6.25 km, and 3.125 km) with an abrupt transition between soft sediment and hard bedrock are: inputGSM01.bedMskLISsqHighRes25kmSymmetric.dat inputGSM02.bedMskLISsqHighRes12p5kmSymmetric.dat inputGSM03.bedMskLISsqHighRes6p25kmSymmetric.dat inputGSM04.bedMskLISsqHighRes3p125kmSymmetric.dat The GSM bed masks with a small (3.125 km) and wide (25 km) transition zone between soft sediment and hard bedrock are: inputGSM05.bedMskLISsqHighRes3p125kmSymmetricSmallSmoothTransition.dat ...
