MARINE ELECTROMAGNETIC SIGNAL ACQUISITION APPARATUS WITH FOLDABLE SENSOR ARM ASSEMBLY

摘要

A marine electromagnetic acquisition apparatus includes a sensor module (22) having at least one sensor associated therewith. A sensor arm assembly (49) is coupled to the sensor module. The sensor arm assembly has at least one sensor arm (22A) and at least one sensor (23B) disposed along the at least one sensor arm. An actuator (50) is coupled to the sensor arm assembly for moving the sensor arm assembly between a folded position and an unfolded position.
