AUTONOMOUS UNDER WATER VEHICLE FOR THE ACQUISITION OF GEOPHYSICAL DATA

摘要

The present invention has, as a first object, an autonomous underwater vehicle equipped for the acquisition of the gravimetric and magnetic gradient near the seabed, characterized in that it comprises: - at least one gravimetric gradiometer; - at least one magnetic gradiometer. In particular, said autonomous equipped underwater vehicle allows underwater explorations as far as 3,000 m. A second object of the present invention relates to an analysis method of the geophysical characteristics of the subsoil, comprising the acquisition of the gravimetric and magnetic gradient in an underwater environment characterized by the following phases: - use of an autonomous equipped underwater vehicle according to the present invention; - immersion of said vehicle to the proximity of the seabed; - navigation along a programmed route; - acquisition and storage of the data collected by said gradiometers and said instruments with correlation to the geographic measurement point; - recovery of the data collected and use thereof for geophysical analysis of the subsoil.
