>theres way more noise pollution along shipping channels just from all the propellers that it is more likely to fuck with whales than sonar
Noise levels in shipping channels are minuscule compared to a sonar ping. We are talking 100 or more extra Db's than a rock concert.

Not to mention water is an extremely effective medium for sound to travel. Whales are routinely fucked up by sonar, we just cant speak their language to understand how endemic the problem (likely) really is. At the very least it affects the hearing of the whales.
