V. CONCLUSION
A pre-loaded fiber optic pressure transducer has been
fabricated that is capable of recording the small variations
in pressure typical of sub-surface wave induced pressure
fluctuations. The transducer had a resolution of ∼2 cmH2 O
which was limited by the analogue to digital converter in the
data acquisition unit used for the tests. A single transducer
has been tested using an analogue detection scheme and
resolutions of 100 individual sensing elements
