Classification: CPC B  G | IPC B  G

Claim 18:
19. Seismic survey apparatus for use on at least one surface vessel, the seismic apparatus comprising:
a seismic source arranged to transmit seismic energy;
a first transceiver apparatus for a first acoustic positioning system to communicate with a plurality of submersible autonomous nodes;
a command control system arranged to provide centralised communication, control and monitoring of the plurality of submersible autonomous nodes;
wherein the command control system is configured to:

i. define a seismic survey schedule, the schedule defined such that the plurality of submersible autonomous nodes can transit within a transit envelope below the water surface and above a seabed along an oscillating path created by a buoyancy system, from a first submarine location to a second submarine location using a second acoustic positioning system;
ii. communicate to each node the seismic survey schedule; and
iii. provide navigation control via the first transceiver apparatus for the plurality of nodes during their final approach to their respective submarine locations, the submarine locations including initial node location and subsequent node locations following node repositioning.
