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.本数据集包含采集于舒马金间隙（Shumagin Gap）阿拉斯加电磁GeoPRISMS实验（EMAGE）测线的海洋可控源电磁（Controlled-Source Electromagnetic, CSEM）数据及其对应的二维电阻率反演模型。本次发布涵盖预处理后的CSEM数据文件、反演流程中生成的最终电阻率模型，以及配套的海底水深地形文件。 文件说明 `EMAGE_CSEM_Line5_s5_m3.data`：预处理后的CSEM数据文件，包含用于反演的实测电磁响应（振幅与相位）。 `202406mainP90.24.resistivity`：MARE2DEM软件输出的二维电阻率模型结果。 `202406mainP90.poly`：反演所用的有限元网格几何形状（多边形文件）。 `202406mainP90.24.resp`：模拟得到的电磁响应数据。 `mare2dem.settings`：反演配置文件。 `bathy_line5_s2d_20240229.txt`：海底水深地形数据。
