Beranzoli The selected observatory for the LIDO Demo Mission in Gulf of Cadiz site is GEOSTAR. Previously GEOSTAR carried out four successful missions in Mediterranean Sea (1997-2005), and one year mission in the Gulf of Cadiz site (2007-2008, EU NEAREST project). After recovery (August 2008), GEOSTAR has been upgraded to meet LIDO Demo Mission scientific and technical requirements, and solve the problems evidenced during the mission (unreliable acoustic modem, seismometer malfunctioning, pressure sensor failure, buoy mooring line failure). The upgraded system (GEOSTAR and communication buoy) was assembled in Vigo, newly deployed during a cruise with Spanish R/V Sarmiento de Gamboa Spanish and it is operative in the Gulf of Cadiz from November, 10 th 2009.

Introduction and motivation On behalf ESONET-NoE, in Novembre 2010 we deployed in the Gulf of Cadiz a Tsunami Early Warning System (TEWS) designed to work in tsunami generation area. The TEWS was developed previously, in the framework of the EU project NEAREST. The core of the system is a tsunami detector. The tsunami detector communicates with a surface buoy through a dual acoustic link. The buoy is connected to land stations via satellite link. The tsunami detector prototype is hosted on board the abyssal station GEOSTAR, and placed above a major tsunamigenic structure. The tsunami detection is based either on pressure events either on seismic events. The bottom pressure data are analysed in real-time at the seafloor by a new tsunami detection algorithm, which can recognize tsunami waves as small as one centimetre. The system was designed for near-field conditions and operated from August 2007 to August 2008, 100 km SW of Cabo de Sao Vincente (Portugal) on behalf NEAREST. The new mission, of behalf ESONET NoE, started on November 11th, 2009 in the same location. The surface buoy has been upgraded, with respect to the first mission, to host bio acoustic sensors for mammals' listening and tracking. We selected the Gulf of Cadiz as test area for multi-parametric long term monitoring because this location is relevant for many topics: tsunami hazard and seismic monitoring, Atlantic-Mediterranean water circulation and climate change, mammals monitoring.

Introduction and motivationOn behalf ESONET-NoE, in Novembre 2010 we deployed in the Gulf of Cadiz a Tsunami Early Warning System (TEWS) designed to work in tsunami generation area. The TEWS was developed previously, in the framework of the EU project NEAREST. The core of the system is a tsunami detector. The tsunami detector communicates with a surface buoy through a dual acoustic link. The buoy is connected to land stations via satellite link. The tsunami detector prototype is hosted on board the abyssal station GEOSTAR, and placed above a major tsunamigenic structure. The tsunami detection is based either on pressure events either on seismic events. The bottom pressure data are analysed in real-time at the seafloor by a new tsunami detection algorithm, which can recognize tsunami waves as small as one centimetre. The system was designed for near-field conditions and operated from August 2007 to August 2008, 100 km SW of Cabo de Sao Vincente (Portugal) on behalf NEAREST. The new mission, of behalf ESONET NoE, started on November 11th, 2009 in the same location. The surface buoy has been upgraded, with respect to the first mission, to host bio acoustic sensors for mammals' listening and tracking. We selected the Gulf of Cadiz as test area for multi-parametric long term monitoring because this location is relevant for many topics: tsunami hazard and seismic monitoring, Atlantic-Mediterranean water circulation and climate change, mammals monitoring. The 2007 and 2009 test missions of GEOSTAR abyssal station are the first step toward the installation of a permanent multi-parametric abyssal observatory in this area.
