On a interesting note:
Titan related, this shark Observer is pinging several GPS tagged sharks in the area of the Titanic and thinks they may be attracted to the remains scent.

I suppose its possible that those in the area might have known.
I saw someone reporting that tagged sharks near the coast knew and reacted. I think we can assume that such a thing is just nonsense or misunderstanding by the reporter. While sound does travel a long way under water, for sharks to react then this would have to happen so often that sharks have come to associate the sound of implosion with meals, meals at a depth that they could reach and somehow gather. I think blood would be carried the wrong way in the current.
A couple of locals swimming around enjoying the smell maybe but responding from anywhere else then no.
Funny. GPS doesn’t penetrate the water.
