| 摘要 |
The invention is a marine geophysical sensor cable (1) with one or more sensor cable sections (2), - each of said sensor cable sections (2) provided with seimic and electromagnetic sensors (10, 20) arranged along said cable (1), - the seismic sensors (10) comprising a hydrophone (11) and a seismic component receiver (12) for seimic vector measurments while said sensor cable (1) being at the seafloor, - the electromagnetic sensors (20) comprising both E-field sensors (22) and H-field sensors (24) - said E-field sensors (22) comprising pairs of first and second electrodes (22a, 22b) arranged with different positions along the cable (1) and connected to a voltage amplifier (23), - The H-field sensors (24) comprising three mutually orthogonally arranged H-field component sensors (24x, 24y, 24z). |
