Autonomous underwater vehicle for marine seismic surveys

An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey, the AUV comprising:

• a body extending along an axis X and having a head portion, a middle portion, and a tail portion, wherein the middle portion is sandwiched between the head portion and the tail portion along the X axis;
• a cross-section of the middle portion, substantially perpendicular on the X axis, having a triangular-like shape;
• the head portion including a base portion having the triangular-like shape and configured to match the middle portion;
• the head portion having a tip that, when projected along the X axis on the base portion to a projection point, the projection point lies on an altitude of the base portion having the triangular-like shape, between a centroid (GC) of the triangular-like shape and a corresponding side of the base portion;
• and
• a seismic payload located within the body and configured to record seismic signals.
