The 2009 final guidelines include the following provisions:
- pre-survey visual observance period of 60 minutes in water depths > 200 m
- PAM is not required on all seismic surveys but is recommended as a ‘best practice’ if seismic surveys are planned to commence at night or during low visibility
- recommend use of new, re-designed Marine Mammal Recording forms (these were developed as part of a JIP-funded project)
-line change procedures are differentiated for airgun array volumes of 500 in3 or larger and volumes 180 in3 or less
In addition to the provisions listed above, there are other differences between the June 2009 guidelines and the previous 2004 version of the guidelines. Therefore, please read the final revised guidelines in their entirety.
