| Abstract | The method of analog physical modeling was applied to study conductivity structure of Antarctic Peninsula and adjusting regions. The 3D scale conductivity model of region from 51.4#2EW to 68.6#2EW and from 60#2ES to 67.2#2ES with factor 1:200000 was created in the electrolytic tank with dimension 54CH54CH0.7 m. according to a bathymetry map. The model was excited by the varying homogeneous magnetic field in the frequency band 6.0-0.1 MHz that corresponds to 2200 - 130000 s. band in natural conditions. The magnetotelluric and geomagnetic response functions was obtained at 12 point along profile across model of Antarctic Peninsula. 2D inversion of obtained response functions was compared with real geoelectric cross section which are reliable known for scale model. This comparison has allowed to estimate the influence of real 3D effects on geoelectric investigation in the region under study. |
