I read all 13 pages of that article and didn't find any discussions refuting the possibility that it could be something else, like some piece of equipment on a submarine. The fact that it's very close to 50Hz mains frequency and is otherwise very "un-whale-like" in behaviour suggests to me that it's man-made. This is probably getting into the realm of conspiracy theory now, but what better than to disguise a submarine to make it sound like a whale, and moreover convince everyone else that it is? Of course if it is actually some highly classified stealth submarine, we may never know... It somewhat reminds me of this: https://en.wikipedia.org/wiki/Peryton_(astronomy) https://en.wikipedia.org/wiki/Peryton_(astronomy)

Given the range over which it operates and how long it has been doing so and the fact that no one has admitted it is one of theirs suggests if it is a submarine, it is one from a major military. Those put considerable resources into making it hard to hear their submarines. This thing is way too easy to hear, which probably rules out submarines.

  If someone were trying to disguise a submarine as a whale, why wouldn't they give it a normal whale voice?

    Because 52Hz might be easier and have some other advantages (like perhaps masking some other more identifiable sounds)?

    why 'trying to disguise', could be inadvertent machine noise?

  Mains frequency has a max 0.2% deviation, which puts your whale well outside of what mains should ever be. And if you're trying to be all conspiratorial about it and suggest it's a submarine... well, how about making the submarine sound like a normal whale first.

Seaman Jones: Uh oh... Beaumont: Buried in the surface clutter... Seaman Jones: Yeeeesssss? Beaumont: I should go to SAPS? Seaman Jones: Correct!
