Abstract
Apparatus which penetrates a hole through an ice cap from the water beneath the ice cap. A positively buoyant unit containing water under high pressure discharges the water through a nozzle causing erosion of the ice. The nozzle is connected to a telescopic tube arrangement the total length of which is at least equal to the ice thickness so that when penetration is made the tube arrangement can act as an antenna for a surveillance sensor package carried by the unit.
