Question

How are marine mammals affected by sonar?

Answer

The link between Navy active Sonar and marine mammal strandings is not fully understood and remains a focus for numerous research activities. Our research indicates that some species tend to leave the area when exposed to sonar and that they return within hours or days after sonar events conclude. In order to reduce the risk of strandings, Navy planners ensure that exercises are not held in conditions that have been linked with stranding events, such as surface ducts and certain bathymetric conditions. Since 2005, the US Navy has used a mandatory suite of world-wide mitigation measures developed to prevent injury to marine mammals.
