SN-1 - The First Italian Seafloor Observatory for Seismic Monitoring

This paper describes how the Instituto Nazionale di Geofisica and Vulcanologia (INGV) is coordinator of an experiment funded in the framework of the 2000-2003 program of the Gruppo Nazionale di Difesa dai Terremoti. The objective of the experiment is to develop and operate a deep-se observatory, namely Submarine Network, mainly to address seismic monitoring. The design and realization of SN-1 has been derived from previous European projects also coordinated by INGV and funded by the European Commission: GEOSTAR and GEOSTAR 2. These projects realized, tested and operate a European prototype of a benthic multidisciplinary observatory, name GEOSTAR. The prototype successfully performed a 7-month deep-sea mission in 2000-2001 in the Southern Tyrrhenian Sea, at around 2000 m w.d. SN-1 was deployed in October 2002, at a depth of 2105 m, around 22 km off-shore of the Eastern Sicily coast. The operating status and the data acquisition are presently checked month through acoustic communication from the sea surface during surveys on the deployment site. The connection to an existing underwater cable for power supply and real-time communication is foreseen in the near future, leading to the integration of the observatory in the existing monitoring networks. The paper presents the state of the art of SN-1 and the future developments.
