Abstract: An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey. The AUV includes a body extending along an axis X and having a front region, a middle region, and a tail region, wherein the middle region is sandwiched between the front region and the tail region along the X axis. The AUV also includes a seismic payload located within the body and configured to record seismic signals. The tail region has a trapezoidal cross-section.

Abstract: An autonomous underwater base for handling an autonomous underwater vehicle (AUV) equipped with seismic sensors for recording seismic signals during a marine seismic survey. The autonomous underwater base includes a storing module configured to store the AUV; an inlet/outlet module configured to control access of the AUV to the storing module; and a control module having a positioning system configured to adjust a position of the base in water. The positioning system autonomously drives the storing module from a first position to a second position underwater.

Abstract: A seismic acquisition system including a source flotilla that includes a first source and a second source for generating seismic waves and a receiver flotilla that includes a first receiver and a second receiver for recording reflected seismic waves. The first source moves independent of the second source, the first receiver moves independent of the second receiver, and the first source and the second source move independent of the first receiver and the second receiver.
