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.
