Fig. 9From: Approximate treatment of seafloor topographic effects in three-dimensional marine magnetotelluric inversion(a) Relative errors of real responses obtained from 25 ocean bottom electromagnetometers (OBEMs) deployed in and around the Philippine Sea (Baba et al., 2010). Circles and stars indicate the errors for each OBEM’s data and their averages, respectively. Dashed lines in the xy- and yx-components indicate 3% error levels. (b) Absolute errors of the MT responses. Circles and stars indicate the errors for the OBEM data and their averages, respectively.Back to article page
