The researcher is a planetary geologist from Cornell, named Gold. The
original reason for investigating the deep sea vents for micro-organisms
came from his idea that nearly all methane is abiogenic. Much to his
surprise, they found TONS of laughing happy methanogens (archae) living
in the heated sediments and the anoxic 300 C to 4 C water column gradient.
