Supplemental Methods and Figures from Dolphins simplify their vocal calls in response to increased ambient noise
Ocean noise varies spatially and temporally and is driven by natural and anthropogenic processes. Increased ambient noise levels can cause signal masking and communication impairment, affecting fitness and recruitment success. However, the effects of increasing ambient noise levels on marine species...

Ocean noise varies spatially and temporally and is driven by natural and anthropogenic processes.
