Acquisition of Distributed Acoustic Sensing (DAS) interrogators

MARMOR project will acquire one DAS interrogator to allow almost continuous measurement of dynamic strain along optical fibers up to many tens of km long measurements along an offshore decommissioned telecom optic fiber between Monaco and Italy (Host: OCA/CNRS).

 Aside from earthquakes, DAS data will be used to study the noise pollution of oceans, to quantify vessel traffic, and to evaluate the dynamic of the shallow and deep-water columns (see ID-FOO Project). OCA will operate the DAS and setup the data flow to the RESIF-SI portal.

 Challenges for DAS technology (e.g. the amount of data (T-bytes per day) and coupling of the optic fiber with the ground), will be both investigated.
