Overview of the fifth international conference on the effects of noise on aquatic life

The Effects of Noise on Aquatic Life took place in Den Haag, the Netherlands, in July 2019. The potential effects on animals ranging from plankton, shrimps, crabs, and lobsters, to fishes, seals, dolphins, and whales were discussed. Reported effects include behavioral responses, auditory masking, cardiac rate changes, stress, a temporary loss of hearing, and perhaps more serious tissue and organ damage. Short-term and long-term, individual and population-level effects were portrayed. Several studies also looked at the fundamentals of animal sound production and perception. One session dealt with the regulation and management of underwater noise. Another integral part of the meeting focused on the sounds and sound sources that might affect aquatic life. As a consequence, underwater noise from pile driving, seismic surveying, shipping, and sonars, as well as from non-anthropogenic sources such as wind and waves was examined. The social program was intended to encourage more leisurely discussions amongst conference participants in order to facilitate networking and the strengthening of relationships. The feedback from conference delegates (submitted via an online survey after the meeting) was very positive
