In this paper, we propose a mathematical model and an appropriate algorithm that allows one-time measurement of the frequency response and phase response of the MET sensor under normal conditions to construct a complex transfer function of the MET at any other temperatures from the allowable range of -35 + 55 °C with the experimental accuracy not worse than a few percent. This model and the algorithm for setting up and selecting thermocompression circuits of electronic amplification and filtration circuits introdu...

The area of underwater seismic and geophysical exploration is now rapidly growing with increasing complexity of the employed equipment. At present, more reliable data are gathered by Ocean Bottom Seismometers - autonomous instruments used in long duration seismic surveys. The general idea behind this equipment is that autonomous devices are unable to transmit data in real-time and require offshore operations for periodical deployment. However, the task of a permanent underwater monitoring for seismic events with o...
