2010, National Physical Laboratory, Marine Aggregates Levy Sustainability Fund (MALSF), Measurement of underwater noise arising from marine aggregate dredging operations

This project has been an extensive study of the noise generated by the UK’s fleet of trailing suction hopper dredgers during marine aggregate extraction. The objectives of the work were (i) to develop a suitable methodology for measuring underwater noise radiated by dredgers, (ii) undertake measurements on UK dredgers at up to four sites and report, whilst disseminating the results to the wider stakeholder community.
