The present invention relates to a dual a ccelerometer vector sensor (DAVS) device. Said device comprises two tri-axial accelerometers and one hydrophone moulded in one unit. Such device is useful to measure and improve the efficiency of methodologies used to perform geophysical acoustic surveys at sea. The DAVS has the potential to contribute to this aim in various ways, for example, owing to its spatial filtering capability, it may reduce the amount of post processing by discriminating the bottom from the surface reflections. Also its compact size allows easier integration with AUVs and hence facilitates the vehicle manoeuvrability compared to the classical towed arrays. Therefore, another object of the present invention refers to an Autonomous Underwater Vehicles (AUVs) comprising the DAVS device of the present invention for acquiring and monitoring underwater seismic data. The present invention is thus useful for acquiring and monitoring seismic data and belongs to the technical field of seismology, seismic prospecting, detecting and monitoring.
