Deep Sea Gravity Measurements: GEOSTAR-2 Mission Results
Main Article Content
Abstract
A new concept gravity meter with sensitivity close to Hz ms / 10 2 8 ? ? in the range of 10 -5 ?1Hz intended for observation of the vertical component of the Earth gravity and
teleseismic waves was implemented at the Istituto di Fisica dello Spazio Interplanetario
(IFSI), CNR and successfully operated during the GEOSTAR-2 mission. The gravimeter has
demonstrated a capability to operate for long time in an autonomous regime and a good
reliability for operation in extreme environments; at the same time the experimental
measurements gave the information for the further gravimeters implementation. Results of
observation and data analysis included the registration of seismic waves excited by global
earthquakes and the evaluation of the low frequency modes of free oscillations of the Earth
are reported.
