    Escaping gas is chilling gulf water?

    The water is near freezing at that depth anyway. The reason the coffer dam did not work is because the compressed methane gas in the oil is expanding and freezing after it combines with the water. And the well oil/gas is not nearly as cold as the water to begin with - I thing maybe 200F or so? It still would end up absorbing a lot of heat from the water if it's starting out 3000PSI over the surface pressure. It has a mile of water to cool off on the way up, but I can't imagine that amounts to much when you consider all the heat in the Gulf water to begin with.
