Common issues between cabled and non cabled observatories in ASSEM project

Abstract

From EU funded project ASSEM (Array of Sensors for Seabed Monitoring of geohazard), some innovative monitoring devices have been demonstrated. The activity on the seabed of a very active seismic area in the Gulf of Corinth in Greece was measured. The parameters driving slope instability were acquired in the Finneidfjord in Norway. From these pilot experiments a discussion of some criteria for the choice of laying cabled observatories or non-cabled subsea observatories is proposed.
