Underwater noise


Manage underwater noise sources during ongoing activities, development/construction, and/or port maintenance activities to reduce impacts to marine mammals.


  • Green Marine recognizes that underwater noise may potentially impact a broader range of acoustic species than just marine mammals. While the initial objective of this indicator covers marine mammals, future development may expand the scope.
  • Applicable only for ports located on salt water.

See below the criteria each port authority has to fulfill to achieve each level of performance.
