Underwater noise


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


  • The working group recognizes that underwater noise may potentially impact a broader range of aquatic species other than just marine mammals. While the initial objective of this indicator covers marine mammals, future development of this Performance Indicator may expand its 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.
