Abstract : Evaluation tests of the vibrotron absolute pressure transducer for detecting small pressure changes under a high ambient pressure were begun two years ago at the Hawaii Institute of Geophysics. This work has demonstrated the feasibility of using this instrument as a sensing element for a tsunami gage system which is bottom-mounted in oceanic depths. The methods of testing and the results are presented together with two possible instrument systems. A successful test in situ at a depth of 1500 meters is described. (Author)
