Sounds of ships and windfarms ‘may alter marine ecosystem’

Underwater sound linked to human activity could alter the behaviour of seabed creatures which play a vital role in marine ecosystems, according to new research. The study found exposure to sounds that resemble shipping traffic and offshore construction results in behavioural responses in certain invertebrate species which live in the marine sediment. These species make a crucial contribution to the seabed ecosystem as their burrowing and bioirrigation activities (how much the organism moves water in and out of the sediment by its actions) are vital in nutrient recycling and carbon storage.
