Chelsea delivers acoustic array to Norwegian university

Oceanography group Chelsea Technologies has delivered an acoustic array to the Norwegian University of Science and Technology (NTNU).

The six-metre-long, oil-filled array houses six omni directional identical hydrophones and is designed to be suspended from a small boat or buoy to depths of 100 metres.

Dr Zhang Guosong of NTNU commissioned Chelsea to build the custom hydrophone array to conduct underwater acoustic experiments in the Trondheim fjord.

His team are looking to exploit spatial diversity in order to research novel communications and acoustic propagations.
