Apparatuses, systems, and methods for the deployment of a plurality of autonomous underwater seismic vehicles (AUVs) on or near the seabed based on acoustic communications with an underwater vehicle, such as a remotely operated vehicle. In an embodiment, the underwater vehicle is lowered from a surface vessel along with a subsea station with a plurality of AUVs. The AUVs are configured to acoustically communicate with the underwater vehicle or a second surface vessel for deployment and retrieval operations. The underwater vehicle and/or second surface vessel is configured to instruct the AUVs to leave the subsea station or underwater vehicle and to travel to their intended seabed destination. The underwater vehicle and/or second surface vessel is also configured to selectively instruct the AUVs to leave the seabed and return to a seabed location and/or a subsea station for retrieval.
