Abstract:

The Philberth probe is a surface-controlled, nonrecoverable instrumented vehicle that can penetrate polar ice sheets down to 3600 m by melting. It can be used to measure temperature, stress, ice movement, and seismic, acoustic and dielectric properties. It can also be used for other investigations with remote instrumentation. The probe consists of a hot point for melt penetration, instrumentation for control and measurement functions, two supply conductor coils to link the probe with the surface for transmission of power and measurement signals, and a reservoir section. The probe is filled with a dielectric fluid. Author
