Abstract We present the first controlled-environment measurements of the optical path-length change response of telecommunication submarine cables to active seismic and acoustic waves. We perform the comparison among integrated (optical interferometry) and distributed (distributed acoustic sensing. DAS) fibre measurements and ground truth data acquired by 58 geophones. 20 three-axis s... https://www.spidertattooz.com/Powell-Mahoney-Bloody-Mary-Mix-750ml/
