I haven’t read this stuff in detail.It’s been in science news for a few years. These researches claim an important role for H2S and the bacteria that handle it, in thermal vents. By now books have been written, such as “The Deep Hot Biosphere” by Thomas Gould. That book has little related to speculation about the origins of life, mostly proven facts.
But, what have you learned, from other papers?
Some links: http://taurus.ubishops.ca/~judy/symb.htm
Most of the stuff is explained in that link….
Other stuff, ocean ridges, etc, related but not as astounding to read:
Karen Von Damm
A professor at the University of New Hampshire, Karen is a geochemist. She studies the chemistry of water sampled from the vents. With graduate student Alison Bray, she stays up all night, running tests on the day’s water samples.
Marv is a geochemist who studies the gases dissolved in the vent fluids. On this trip, he has also been trying to isolate bacteria that make their living from those gases. He’s at the University of Washington, Seattle.
Also from the University of Washington, Eric takes the day’s water samples and runs them through an astonishing machine that captures the gas for study back in Seattle. He’s known as “Exxon” for the odors his machinery releases at the end of a run.
A former student of Marv’s, Betsy just took a job at Rutgers. On this cruise, she has been studying bacteria that produce energy from hydrogen, as opposed to photosynthesizing from the sun or chemosynthesizing from sulfur.
