MEDUSA is a new marine monitoring system based on instrumented buoys operating in the Gulf of Pozzuoli (close to Naples, Italy) within the local surveillance system of the Campi Flegrei volcanic caldera. It mainly monitors the local seismicity and the seafloor ground movements. MEDUSA consists of four buoys equipped with geophysical and oceanographic instrumentation and continuous and real time data acquisition and transmission to the Monitoring Center of INGV in Naples, where data are integrated to those acquired by the land networks.
MEDUSA implementation is based on the previous experience gained during the realization of CUMAS - Cabled Underwater Multidisciplinary Acquisition System, the first prototype of instrumented buoy operating the Gulf of Pozzuoli since 2008. By CUMAS we have acquired new expertise in the design and management of marine fixed monitoring systems in shallow waters and achieved valuable benchmarks in the field of geophysical monitoring technologies.
MEDUSA system is the result of the close collaboration between different groups inside INGV Departments (Osservatorio Vesuviano and Rome-2 ) and is part of the marine infrastructures developed in the EMSO-MedIT national project. This project was funded by MIUR (Italian Ministry of Education of the University and Research) as a contribution to one of ESFRI European Research Infrastructure, EMSO - European Multidisciplinary seafloor and water column Observatory. MEDUSA will help to better control and understand the evolution of the volcanic activity in the marine sector of the Campi Flegrei so far not fully understood yet.
