A submersible node and a method 10 and system 100 for using the node to acquire data, including seismic data is disclosed. The node incorporates a buoyancy system 16 to provide propulsion for the node between respective landed locations by varying 5 the buoyancy between positive and negative. A first acoustic positioning system is used to facilitate positioning of a node when landing and a second acoustic positioning system is used to facilitate a node transiting between respective target landed locations.
