Claim Text:
1. An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey, the AUV comprising: a body having a base and sides; a propulsion system for guiding the AUV to a target on the ocean bottom; a pump-jet connected to an inlet and plural base outlets, wherein the plural base outlets are distributed on the base; a processor connected to the pump-jet and configured to activate the pump-jet when the base is on the ocean bottom; and a seismic sensor configured to record seismic signals while the AUV is buried in the ocean bottom, wherein the pump-jet has a first speed so that water jets expelled at the plural base outlets fluidize the ocean bottom underneath the base and buries the AUV.
