The effects of seismic activity on marine mammals in UK waters, 1998-2000
Marine mammals use sound to communicate and, in some cases, echolocate. The ability to detect calls from conspecifics, echolocation signals and other natural sounds is of paramount importance to them. Man-made sounds thus have the potential to interfere with their natural functions, such as feeding, social interactions (including breeding) and navigation, as well as having the potential to cause physical harm. Concern over the issue of acoustic disturbance to marine mammals has led to attention being focussed on seismic surveys as one of a number of potential sources of such disturbance. Seismic surveys use airguns to generate sound at low frequencies for geophysical purposes. These low frequencies overlap with those used by baleen whales. In addition, the airguns incidentally emit higher frequency sounds (Goold and Fish 1998) that overlap with those used by toothed whales and dolphins (odontocetes). Therefore, most species of cetacean may be affected by sounds produced during seismic surveys, peaked in August, with most occurring to the west of Shetland and in the northern North Sea, which reflected the location and timing of surveys - JNCC Report
