OCEANCARE:
Marine animals are dependent on their hearing to navigate, communicate, find a mating partner and catch prey. But sound levels in the oceans are rising constantly. Military sonars used to locate submarines are a particular danger, as their sound waves can be heard within an underwater radius of about 3,000 kilometres. Shipping, offshore oil platforms and the use of airguns in seismic oil & gas explorations all add to the ear-battering racket.
