ABSTRACT:
A method and apparatus for measuring the thickness of an ice sheet floating on a body of sea water is disclosed. The electrical inductance of a coil embedded in an ice sheet is measured. This inductance is solely dependent on the geometrical factors of the coil and is minimally affected by variations in salinity of the sea water on which the ice sheet is floating. The measured inductance is the actual inductance only of the part of the coil in the ice. The other part of the coil, protruding in the sea water, is shorted out by the sea water. Hence, the thickness of the ice sheet is directly related to the measured inductance.
