Abstract
Apparatus for use in determining electric potentials underwater includes Luggin tubes of small diameter which are open to the water at outer ends thereof. The outer ends are arranged at known spaced positions relative to one another. The potentials at the ends of the tubes are connected selectively via fluid in the tubes to a reference electrode. The potential at the reference electrode relative to a further electrode is measured.
