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