It is using Sonar-dyne’s Fetch instrument (functionally equivalent to the AMT, but with a much bigger battery that enables deployments of up to 10 years) for the seabed com-ponent of the study. The technology is also the basis of a Japanese Govern-ment funded collaboration between the University of Kyoto, Universidad Na-cional Autónoma de México and New Zealand’s GNS Science; “Hazard As-sessment of Large Earthquakes and Tsu-namis in the Mexican Paci? c Coast for Disaster Mitigation”. Further signi? cant programs are also being proposed.PRECISE, ACCESSIBLE INSIGHTOur seabed deformation monitoring system is giving operators and scientists centimetric detail of sea? oor movement, to help manage and maximize their re-sources and monitor submarine plate tectonic movements in far greater detail than they have ever been able to do be-fore, all at a fraction of the cost of previ-ous methods.www.marinetechnologynews.comMarine Technology Reporter 53MTR #2 (50-65).indd 53 3/11/2019 2:22:22 PM
