Magnetotelluric (MT) data were recently collected on Brøggerhalvøya, Svalbard, in a 0.003– 1000 s period range along a curved WNW–ESE profile. The collected data manifested strong three-dimensional (3D) effects. We modelled the full impedance tensor with tipper and bathymetry included in 3D, and ben...
