Ocean Bottom Seismograph:Instrumentation and Experimental Technique


A set of Ocean Bottom Seismographs (OBS) has been constructed recently at the National Taiwan Ocean University (NTOU) for offshore seismic surveys and earthquake observations. The instrument is identical in design to the recently upgraded Texas OBS. It is controlled by an 80C88 microprocessor. Signals from up to four channels of sensors are recorded digitally R/V Ocean Researcher I cruise No. 227 in 1991, and has been in use in subsequent cruises.
