New deep-sea hydrothermal vents, life form discovered
04-19-2007 · EurekAlert!A new "black smoker" -- an undersea mineral chimney emitting hot springs of iron-darkened water -- has been discovered at 8,500-foot depths by an expedition funded by the National Science Foundation to explore the Pacific Ocean floor off Costa Rica.

- Hydrothermal vents: Hot spots of microbial diversity
10-04-2007 · EurekAlert!
Thousands of new kinds of marine microbes have been discovered at two deep-sea hydrothermal vents off the Oregon coast by scientists at the MBL and University of Washington's Joint Institute for the Study of Atmosphere and Ocean. Their findings, published in the Oct. 5 issue of the journal Science, are the result of the most comprehensive, comparative study to date of deep-sea microbial communities that are responsible for cycling carbon, nitrogen, and sulfur to help keep Earth habitable.

- Deep in the ocean, a clam that acts like a plant
02-20-2007 · EurekAlert!
How does life survive in the black depths of the ocean? At the surface, sunlight allows green plants to "fix" carbon from the air to build their bodies. Around hydrothermal vents deep in the ocean live communities of giant clams with no gut and no functional digestive system, depending on symbiotic bacteria to use energy locked up in hydrogen sulfide to replace sunlight. Now, the genome of this symbiont has been completely sequenced.

- Lost City pumps life-essential chemicals at rates unseen at typical black smokers
01-31-2008 · EurekAlert!
Hydrocarbons -- molecules critical to life -- are being generated by the simple interaction of seawater with the rocks under the Lost City hydrothermal vent field in the mid-Atlantic Ocean. Being able to produce building blocks of life makes Lost City-like vents even stronger contenders as places where life might have originated on Earth.

"Editors' Choice" in the current issue of Science magazine, tags them, "Singing Vents." Long assumed to be silent, fluids in black smoker hydrothermal vents not only produce a rumbling sound but, as an added surprise, are producing resonant tones. Have a listen to what University of Washington scientists have recorded.

- Life-giving rocks from a depth of 250 km
09-26-2007 · EurekAlert!
If our planet did not have the ability to store oxygen in the deep reaches of its mantle there would probably be no life on its surface. This is the conclusion reached by scientists at the University of Bonn who have subjected the mineral majorite to close laboratory examination. Majorite performs an important function as an oxygen reservoir. Near the Earth's surface the mineral breaks down, releasing oxygen, which then binds with hydrogen from the Earth's interior to form water.
