Abstract:
1. An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey, the AUV comprising: a body that is configured to be selectively steered to land on the bottom of the ocean; wherein the body has a front end and a tail end, wherein a cross-sectional profile of the body is substantially uniform from the front end to the tail end, and wherein the front end and tail end have substantially similar shapes, and an intake water element located on the body and configured to take in water when deployed underwater; at least one propulsion nozzle located at the tail end of the body and configured to eject the water taken from the intake water element for propelling the AUV; at least one guidance nozzle located on the body and configured to eject water to change a travelling direction of the AUV; and a seismic payload located on the body of the AUV and arranged to record seismic signals while the AUV is resting on the bottom of the ocean.
