Hot Water, Hot Earth

Calopteryx notes a New Scientist article on the discovery of "supercritical" water emerging from a vent in the Atlantic Ocean at 407 deg. C (765 deg. F). One of its discoverers actually said, "It's water, but not as we know it"; it's the hottest water ever found on earth. The cause seems to be a huge bubble of magma beneath the ocean floor, 3 km below the sea surface. Meanwhile Nymz shares a journal entry on a hot spot on land: a 2-acre patch in Ventura county, in California, that has heated up to 433 deg. C (812 deg. F). Here geologists blame buried hydrocarbons burning as they get access to air through cracks in the ground. That high temperature was measured a foot below the ground surface.

The Year Was 1977 ...

I think I saw a special about black smokers on TV, I believe they were discovered in 1977 and I remember watching an interview of miniature sub (Alvin) pilot explaining that his temperature sensor melted when they came upon one of them and he decided to get a reading. If I recall the anecdote correctly, they were slowly drifting toward it as his friend explained to him that the hull of their craft was made of the same metal as the thermometer. He then very carefully began to operate the propellers in reverse.

I think it was even back then that speculation began of life starting around this geothermal energy. That these minerals only populated the sea and made for nutrient rich sea water in which life could propagate.

The only news here is that the 400 ÂC has been passed on record. I think everyone knew these could get insanely hot.
