Abstract

The investigation of the seabed is a major concern for the offshore mining, cable installation and<br>dredging companies. SAGE proposes two new tools based on geo-resistivity and seismic refraction<br>methods to address these requirements. While acoustic based methods (subbottom profiler, seismic<br>reflection) give structural information of the upper part of the seabed, geo-resistivizy and seismic<br>refraction give a measurement of the resistivity and of the seismic velocity for the investigated part of the<br>seabei The measurements can be correlated to in-situ geotechnical data such as coring, CPT,<br>vibrocores, etc...<br>In this paper, the REDAS and SEABIRD techniques will be presented and typical data will be shown,<br>validated by ground truthing with cores and CPT data.
