Development of an Advanced Ocean-Bottom Sensor System, ONR Contract N00014-77-C-C0606 (Final Technical Report, period covered 15 August 1977 - 31 December 1982)
MetadataShow full item record
A low-cost, light-weight, long-life ocean-bottom sensor system has been developed. It incorporates three microprocessors, which control data acquisition, intermediate processing, and recording, all in digital form. The system has been used successfully in several seismic field experiments, which include detection of natural earthquakes, seismic refraction surveys and investigation of acoustic wave propagation.
