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...
