Previously initial tests were reported by one of the authors on an existing ocean bottom seismometer (OBS) which uses velocity sensors (geophones). Geophysicists have used OBS instruments primarily to time discrete seismic events. This paper describes a new OBS designed to measure sea floor vibration amplitudes, down to the ambient noise level, in the 1-50 Hz range. The design goal was to minimize both the self noise (an additive effect), and the multiplicative effect of the transfer function which relates sea floor motion to the motion recorded by the OBS ER -
