Almost 10 years have passed from the 1st experiment in Europe with GEOSTAR multiparameter seafloor<br />

observatory developed within EC projects. After that experience, many other developments and<br />

experiments has been completed both at European level (GEOSTAR-2, ORION-GEOSTAR-3, ASSEM) and<br />

at National level (NEMO-SN1). The presentation gives an overview of the technical-scientific solutions<br />

adopted for realisation of sensor prototypes, sensors installation and data quality control. The<br />

inadequacy of some sensors is also discussed. Finally the benefits of a multiparameter approach for the<br />

data quality assessment will be presented.<br />

Keywords: multiparameter, sefloor, observatory
