Annex 4.A note of the Recommendations from the 2004 meeting of the Scientific Committee of theInternational Whaling Commission.At its 2004 meeting, the Scientific Committee of the International Whaling Commission (thelargest annual gathering of cetacean scientists) made a special review of the anthropogenic effectsof noise on marine mammals. Several invited experts contributed to this review and itsconclusions and recommendations were reviewed and endorsed by the full Scientific Committee(IWC, 2004).Potential impacts resulting from chronic or acute exposure to loud noise were discussed andincluded those resulting from the increasing use of powerful sound sources – for example seismicairgun arrays and military sonars - as well as increasing levels of ambient noise from shipping.The spatial and temporal scales over which impacts may occur can differ by several orders ofmagnitude. For example: low frequency (
