HOTSPOT results: Download the ICEMAN and ICECRT models

From here you can download the raw model files along with code to extract P-and S-velocities from the raw model data files. For more details on the development and resolution of the models see the brief web page descriptions: ICEMAN | ICECRT, or the full publications: ICEMAN | ICECRT.

Iceland Mantle Models: ICEMAN Download and save the following seven files. extracticeman.f - fortran77 code to extract velocities from the model data files (ascii) ICEMAN-S - model data file (ascii) ICEMAN-LP - model data file (ascii) ICEMAN-HP - model data file (ascii) model.cube.iceman - grid info file for all three models (ascii) icein - example input file for extracticeman (ascii) iceout - output expected for the example input (ascii) Once you have the files, compile the fortran code and execute it in the same dir as where you save the model data files. The code takes an input file, see the top of extracticeman.f for a description of the necessary input and output. An example input file (icein) and the expected output (iceout) is also included.

Iceland Crustal Model: ICECRTb 3D velocity model (includes velocity variation across the moho) Download and save the following five files. extracticecrt.f - fortran77 code to extract velocities from the model data file (ascii) sol.ICECRTb.abs - model data file (ascii) model.cube.ICECRTb.abs - grid info file for the model (ascii) icecrtin - example input file for extracticecrt (ascii) icecrtout - output expected for the example input (ascii) Once you have the files, compile the fortran code and execute it in the same dir as where you save the model data files. The code takes an input file, see the top of extracticecrt.f for a description of the necessary input and output. An example input file (icecrtin) and the expected output (icecrtout) is also included. Crustal thickness map The file ICECRTb.mohomap.griddata contains lat lon and crustal thickness (km) for the box 63 to 67 deg lat, -25 to -13 deg lon. The grid increment is 0.044943820685148 deg in both lat and lon directions, there are 267 grid points W-E and 89 N-S. Note that the crustal thickness is only constrained where there is local surface wave coverage (see manuscript) which approximately corresponds to onshore Iceland. Iceland's crustal thickness varies from ~15 km around the coast to 46 km in the center.
