Paper Context: The study area is adjacent to the shipping lanes into Delaware Bay (electronic supplementary material, figure S1 ) and had ambient noise levels comparable to other coastal areas with frequent vessel traffic . If a vessel is located in a different direction from conspecifics, there may be a decrease in masking (spatial release from masking) , but the observed changes in the whistle signals indicate that the dolphins simplified their calls to counter the masking effects of vessel noise. Ambient noise levels are likely to rise in the future as vessel traffic increases and an offshore wind energy facility is proposed.
