There seems to be some issues with this experiment if you can call it that. Were acoustic measurement/ spectrum analysis done when boats were fishing the area? If not what is the benchmark to determine if banning them is a success. Hopefully it’s more specific than a less boats= less background noise, therefore no need to actually measure and see if it’s accomplishing anything. If that’s the end game,then nothing short of complete closure for all vessels will be a 100% solution, so failing that what % of reduction is the target?
Are hydrophones currently collecting data currently, and if so will they analyze seasonal differences, ambient noise levels and or specific frequency range noise level ?Will the summer boating season when many pleasure craft transit the area be analyzed? Will the noise levels when Whales are not present be compared to when they and Whale Watchers are present?
I suspect that no measurables have been established, so guess what? Recreational Fishing Closure was the answer!
