Multiple Sound Source Synchronizer for Seafloor Surveying


The need to avoid interference between sound sources during seafloor surveys led to the design and assembly of a device which automatically controls the firing rate of different sound sources on board a ship. This synchronizer is built around a Z80 microprocessor which schedules the timing of a single channel seismic system, a 3.5 kHz subbottom profiler and a Sea Beam bathymetric survey system. The paper describes the design characteristics and the implementation of this synchronizer aboard the R.V. Thomas Washington.
