Sea-surface observations of the magnetic signals of ocean swells

Lilley, Frederick (Ted); Hitchman, A; Milligan, P; Pedersen, T.

Description

Ocean swells have a magnetic signal, caused by the motional induction of sea water moving in the steady main magnetic field of Earth. To check the character of such signals at the sea surface, a magnetometer has been set free from a ship to float unrestricted on the surface of the ocean for periods of several days. The path of the floating magnetometer was tracked by satellite; this procedure enabled also the eventual recovery of the magnetometer by the ship. Superimposed upon a background of...[Show more]
