When transporting the two whales and seawater into the tank in the Star Trek movie The Voyage Home, what happened to the air in the tank? I've read the question and answers about regular transportation. One suggestion is that during the time it takes for rematerialization, the air is pushed aside. But the whales and water are transported into a sealed tank. Or should we presume that the top of the tank is open? Even then, that's a lot of air to displace. Whoosh!
And what about water splashing out when the whales swim around? Then there's the problem of making sure that the water is oxygenated enough. Separate questions, I know, but still . . .
