Response function of the magnetic field for different sea depths.
Showing amplitude (top) and phases (bottom) of the response function of the vertical magnetic field Z(ω; h, σ′) as a function of the period ( = 2π/ω) (as shown in Equation (5) and (6), respectively of the Methods) for the depths h = 7000, 5000, 3000, 1000, 500 and 200 m and for σ′ = 0.
