The present disclosure generally relates to systems and methods for acquiring seismic data. In one exemplary embodiment, a method for acquiring seismic data is described in which recorder instruments are deployed to the seafloor and utilized for recording pressure wave and shear wave data. An acoustic array, displaced from the seafloor, is also provided for sending acoustic signals to the instruments on the seafloor. The orientation of the instruments on the seafloor is determined via acoustic communication between the acoustic array and the instruments. Related systems and methods for acquiring seismic data are also described.
