On October 9th, 2002, the seafloor observatory SN-I (Submarine Network -1) was successfully deployed in 2105 m w.d. offshore Catania (Southern Italy) and was successfully recovered on May 12th, 2003. The observatory worked properly for 130 days (depending on the power of the lithium battery), acquiring high quality seismic, gravimetric and environmental signals. SN-I has been developed within a project funded by the Italian National Group for the Protection against Earthquake (GNDT) and co-ordinated by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) and takes advantage of a partnership including Universities, Research Institutes, and the industrial company Tecnomare (EN1 Group). SN-1 was straightforward derived from the previous GEOSTAR observatory, funded by the European Commission in the period 1995-2001, which performed a deep-sea mission of 7 months in 2000-2001 at about 2000 m w.d. in the southern Tyrrhenian Sea. In the next future SN-1 observatory will be connected to a submarine cable owned and deployed by the Italian National Institute for Nuclear Physics (INFN), having the main purpose to support a scientific pilot experiment of natural neutrino detection in deep sea (NEutrino Mediterranean Observatory, NEMO Project). This will make possible the real-time data transmission and communication, and therefore the complete integration of SN-1 to the existing Italian land-based network, and significantly contribute to the knowledge of a key sector of the central Mediterranean Geodynamics. Presently SN-1 is the longest worldwide seismological experiment (130 days) on the deep seafloor.

“…The most transformative aspect of the observatory design will be its ability to address interdisciplinary objectives simultaneously across scales and relate that information to researchers and hazard managers in a timely manner. Various designs have been under consideration for more than a decade (Thiel et al 1994, Berta et al 1995, Rigaud et al 1998, Beranzoli et al 2002, Priede et al, 2003, Blandin and Rolin, 2005, Favali et al 2006a, Frugoni et al 2006). These tools can be brought to bear in the water-column, on the seafloor, and sub-seafloor depending on the application Ocean observatories can be attached to a cable providing power and data transfer or operate as independent benthic and moored instruments.…”

We assess the first mission of the GEOSTAR (GEophysical and Oceanographic STation for Abyssal Research) deep-sea multidisciplinary observatory for its technical capacity, performance and quality of recorded data. The functioning of the system was verified by analyzing oceanographic, seismological and geomagnetic measurements. Despite the mission's short duration (21 days), its data demonstrated the observatory's technological reliability and scientific value. After analyzing the oceanographic data, we found two different regimes of seawater circulation and a sharp and deepening pycnocline, linked to a down-welling phenomenon. The reliability of the magnetic and seismological measurements was evaluated by comparison with those made using on-land sensors. Such comparison of magnetic signals recorded by permanent land geomagnetic stations and GEOSTAR during a "quiet" day and one with a magnetic storm confirmed the correct functioning of the sensor and allowed us to estimate the seafloor observatory's orientation. The magnitudes of regional seismic events recorded by our GEOSTAR seismometer agreed with those computed from land stations. GEOSTAR has thus proven itself reliable for integrating other deep-sea observation systems, such as modular observatories, arrays, and instrumented submarine cables.
