<p>There is provided an underwater measurement system (20, 30, 40) for monitoring an underwater region (10). The system (20, 30, 40) includes a sensor assembly operable to sense at least one physical variable in the region (10) for generating at least one corresponding sensor signal, and a data processing arrangement (170, 510, 520) for processing the at least one sensor signal to generate processed data for presentation and/or logging. The sensor assembly (20) includes one or more voltage sensors (190) configured to sense electric fields present in the underwater region (10) and provide information in the at least one signal indicative of the electric fields. Moreover, the sensor assembly (20) includes one or more hydrophones (200) operable to receive sonic energy generated in the underwater region (10) and to include corresponding information in the at least one sensor signal for communicating to the data processing arrangement (170, 510, 520).</p> |
