OPERATORS UNDERTAKING A SEISMIC SURVEY ARE REQUIRED TO:

Have present two independent trained marine mammal observers and two passive acoustic monitoring operators. Record all observations/sightings of marine mammals before and during operations. Have regard to the mitigation zones. 1.5km radius for species of concern with young, 1km for species of concern without young, and 200m for all other species. The acoustic source must be stopped if any marine mammals enter the relevant mitigation zones. Use the lowest practical acoustic source volume for the survey that will still achieve survey objectives. Conduct 30 minutes of pre-observation prior to commencing the soft-start procedures, which slowly builds up the source volume over a period of 20 minutes.
