    I always just figured the whales were committing suicide. That's what they wanted to do so no one should try to push em back into the water.

    They have a "right" to kill themselves.

    Although this has always been so interesting a subject to me, I've never taken the time to research it much. I've read that sometimes one is sick or old and their navigation systems become faulty. Any of the whales following the leader simply become stranded right along with that one.

    It could also be El Nino. Whatever it is, it's sad, they're so old and awesome.

    I always figured that people like yourself are ignorant, selfish, and care nothing about the world that you are handing to our children. In fact, care nothing at all about our children as long as you have gotten "yours".

    Must be stifling, living within the bars of your own selfishness, prevented from seeing to world by walls of ignorance that are self constructed.

    At first we were using standardize "Marine Mammal Mitigation" measures. Watches were trained in whale spotting and then stationed as lookouts. Where technologically possible, passive sonar was monitored by another trained individual listening for whale calls and echo ranging. Any contact within a given range required immediate sonar shutdown and it could not be bought up again till the lookouts had no sightings for 30 minutes.

    This was taken much more seriously in PACFLT than LANTFLT. In San Diego harbor we've been stopped due to the appearance of a sea turtle. I appreciate that and feel the for turtle (he's an air breather so he's got air behind his ear drums and sonar will hurt him) but it surprised me to see sailors taking such a liberal interpretation.
