Abstract

An airborne electromagnetic surveying system including one or several buoyant elements, particularly adapted to be towed by a helicopter. A transmitter assembly consists of a transmitting loop, a transmitter and a power supply. A receiver assembly consisting of a buoyant element carrying at least one receiving coil is towed behind the transmitter assembly whereby the buoyant element stabilizes the motion of the transmitter assembly during towing by an aircraft. This buoyant element contributes a large part to the overall performance of the system allowing for a large separation, hence use of increased radiated power as well as a stable geometry.
