Paolo Favali’s SN-4 (Submarine Network-4, Geostar) sea floor observatory system including the folling sensors: broad-band 3-component seismometer; hydrophone triaxial, single-point current meter; CTD (conductivity, temperature and depth) sensor CH 4 sensors (at least 2 in parallel) O 2 sensor

Other sensors to monitor fluid seepages and mass flows: 1.Time-lapse cameras with one or two pictures a week to monitor fluids, mass-flows bacterial growth, benthic fauna, etc. 2. Optical backscatter sensors (or turbidometers) to monitor water turbidity and sediment influx.
