2D interpretation of land and seafloor magnetotelluric data at the Horonobe coastal area

Abstract We conducted magnetotelluric (MT) field measurements on land and under shallow sea in Horonobe, northern Hokkaido, Japan. We have applied two-dimensional (2D) inversion to land and seafloor MT data simultaneously to obtain seamless resistivity model across the shoreline. In order to deal with both TE- and TM-mode data, static shifts are incorporated as unknowns in the inversion. 2D models by the inversions for two survey lines indicate
