While that's certainly possible, then you'd see this same scenario occurring all around the world where sonar is used for mapping around shipping lanes and whale migratory paths. Now I don't keep up with any news with stuff like that, so maybe it has been witnessed before, but I personally would need to see this scenario being seen elsewhere to truly be on board that sonar right now off our coast is to blame. There could also be a litany of other factors around our shoreline specifically that could be attributed to it too. Cleaner waters than we've had in the past could be leading to a healthier ecosystem with more fish and shrimp-esque organisms the whales will feed on, drawing them closer to shore and into shipping lanes. I've also seen theories of disease circulating around populations off our coast, which of the organisms are tested and that's found to be the case, would be a factor then. It should certainly be looked at, and if proven to have an actual correlation with the sonar, then yes it should be addressed. I haven't looked at any data, but if there's been an increase in beachings over the last several years preceding any mapping occurring, then that would point to something else being a cause as well.
