Abstract
Active and passive seismology require high-resolution,
low-level signal acquisition. In both methods,
the equipment most widely used to acquire seismic
data in the marine environment is an ocean bottom seismometer
(OBS). We designed and built a high-resolution acquisition
system prototype for an OBS that is mainly used in active
seismic experiments in which maps are generated of the width
and material of ocean bottom sublayers. Other OBS system applications,
in which the objective is to estimate the location and
magnitude of an earthquake require higher autonomy. When
an OBS is used in a permanent seafl oor observatory with no
power supply limitation, it can generate tsunami alert signals
to shore.
