Controlled-Source Electromagnetic Data from EMAGE Trench-Normal Profile at the Shumagin Gap

This dataset contains marine Controlled-Source Electromagnetic (CSEM) data and the corresponding 2D resistivity inversion models from the ElectroMagnetic Alaskan GeoPRISMS Experiment (EMAGE) survey profile in the Shumagin Gap. This release includes the processed CSEM data file, the final resistivity models generated during the inversion process, and the associated bathymetry file. File description `EMAGE_CSEM_Line5_s5_m3.data`: The processed CSEM data file containing observed EM responses (amplitudes and phases) for inversion. `202406mainP90.24.resistivity`: 2D resistivity model output from MARE2DEM. `202406mainP90.poly`: The finite element mesh geometry (polygon file) used for the inversion. `202406mainP90.24.resp`: The modeled responses. `mare2dem.settings`: Inversion configuration file. `bathy_line5_s2d_20240229.txt`: Seafloor bathymetry.
