Summary The variation with depth of the currents induced in the oceans is considered in reference to a model Earth completely covered by an ocean of uniform depth. The effect of the conductivity of the underlying earth is taken into account. The results show that for variations in the inducing field with periods up to 10 s, the ordinary plane skin effect formula can be applied, and that for variations with periods from 1–24h (including those of the Sq field) the current intensity is almost the same at all depths in the ocean.
