Impact assessments for sonar operations typically use received sound levels to predict behavioural disturbance in marine mammals. However, there are indications that cetaceans may learn to associate exposures from distant sound sources with lower perceived risk. To investigate the roles of source di...

Impact assessments for sonar operations typically use received sound levels to predict behavioural disturbance in marine mammals.
