A self-contained seismic station that has a modular structure adjustable to different operational conditions—like onshore, offshore to 500-m depth, and at transition zones—has been developed and field tested. The station operation frequency band is 1–300 Hz, which is wider than that of the majority of seismic stations based on using standard (10 Hz) geophones. Such improvement was achieved through the use of molecular-electronic transfer seismic sensors that allow for covering a low-frequency part of the spectrum that is needed for broadband processing and receiving information on subsurface formation. Basically, the system includes a module of sensing elements, a module of digital electronics, and a battery module. Optionally, a self-surfacing module could be used. The field test of the station was performed in August 2016 in the Sea of Azov.
