ADVANCED OCEAN-BOTTOM SEISMOMETER

Abstract

The five advanced ocean-bottom seismic monitoring and recording devices incorporate many features of the prototype units, with improvements suggested through experience, and field testing. Major advantages of the new systems are: (1) Capable of operation to 20,000 feet versus 10,000 feet previously; (2) Choice of using a tripod type base as well as the original pointed nose cone; (3) Addition of an overload circuit which eliminates amplifier shock susceptibility; (4) Increased dynamic range by dual-level recording which provides 72 db over-all versus 36 db previously; (5) Addition of a calibration signal applied to each trace every hour; (6) Simplification of power requirements to one rechargeable
