FloaTEM is a transient electromagnetic method for data acquisition on water and is a further development of the land based tTEM systems. The system is towed behind a boat with the transmitter and receiver coils resting on pontoons. With dense survey lines a 3D coverage is obtained down to a depth of 30-70 m, depending on the water conductivity.

The system is quick to deploy and easily managed by a field crew of two persons. Data from the FloaTEM system is fully integrated with the Aarhus Workbench software package for data processing, inversion and reporting.
