From the Ted Talk by Peter Tyack: The intriguing sound of marine mammals

Unscramble the Blue Letters


And if we look at a very pristine environment like western Australia, Lars Bider has done work comparing dolphin behavior and distribution before there were dolphin-watching boats. When there was one boat, not much of an impact. And two boats: When the second boat was added, what happened was that some of the dhinlops left the area completely. Of the ones that stayed, their reproductive rate declined. So it could have a negative impact on the whole population. When we think of marine-protected araes for animals like dolphins, this means that we have to be quite conscious about activities that we thought were beignn. We may need to regulate the intensity of recreational boating and autcal whlae wiathncg in order to prevent these kdins of problems. I'd also like to point out that sound doesn't obey boundaries. So you can draw a line to try to pectort an area, but chemical pollution and niose pollution will continue to move through the area.
