Read MoreMaking Organic Molecules in Hydrothermal Vents in the Absence of Life
In 2009, scientists from Woods Hole Oceanographic Institution embarked on a NASA-funded mission to the Mid-Cayman Rise in the Caribbean, in search of a type of deep-sea hot-spring or hydrothermal vent that they believed held clues to the search for life on other planets. They were looking for a site with a venting process that produces a lot of hydrogen because of the potential it holds for the chemical, or abiotic, creation of organic molecules like methane – possible precursors to the prebiotic compounds from which life on Earth emerged.
For more than a decade, the scientific community has postulated that in such an environment, methane and other organic compounds could be spontaneously produced by chemical reactions between hydrogen from the vent fluid and carbon dioxide (CO2). The theory made perfect sense, but showing that it happened in nature was challenging.
Now we know why: an analysis of the vent fluid chemistry proves that for some organic compounds, it doesn’t happen that way.
New research by geochemists at Woods Hole Oceanographic Institution, published June 8 in the Proceedings of the National Academy of Sciences, is the first to show that methane formation does not occur during the relatively quick fluid circulation process, despite extraordinarily high hydrogen contents in the waters. While the methane in the Von Damm vent system they studied was produced through chemical reactions (abiotically), it was produced on geologic time scales deep beneath the seafloor and independent of the venting process. Their research further reveals that another organic abiotic compound is formed during the vent circulation process at adjacent lower temperature, higher pH vents, but reaction rates are too slow to completely reduce the carbon all the way to methane.

Read MoreScientists Release First Images of Hydrothermal Vents Found in the Indian Ocean
Scientists exploring a remote area of the central Indian Ocean seafloor two and one-half miles deep have found animals that look like fuzzy snowballs and chimney-like structures two stories tall spewing super-heated water full of toxic metals. The findings, released on the Woods Hole Oceanographic Institution’s Dive and Discover Web site (http://www.divediscover.whoi.edu/) were made at the start of a month-long expedition funded by the National Science Foundation. Images and data from the seafloor may provide critical answers to long standing questions about the diversity of life in the deep sea, how animals move from place to place and how the ocean crust is changing. A Japanese team is reported to have discovered hydrothermal vents in the Indian Ocean last fall, but little information has been publicly available.

Read MoreStudy Tests Theory that Life Originated at Deep Sea Vents
One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about exactly how life began. One possibility – that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world – has grown in popularity in the last two decades.
Recent research by geochemists Eoghan Reeves, Jeff Seewald, and Jill McDermott at Woods Hole Oceanographic Institution (WHOI) is the first to test a fundamental assumption of this ‘metabolism first’ hypothesis, and finds that it may not have been as easy as previously assumed. Instead, their findings could provide a focus for the search for life on other planets. The work is published in Proceedings of the National Academy of Science.
