Life under extreme contidions, microbiology of the hydrothermal vents
Microorganisms are found everywhere, even under the most extreme environmental conditions. These include extremely high temperature environments in which growth of certain Archaea - the most primitive forms of life - is possible at temperatures up to 110oC or higher, and hypersaline environments saturated with salt. The deep-sea hydrothermal vents... view more... (2003-05-29)
British oceanographers find 'smoking' submarine volcano in the Indian Ocean
At over three thousand metres down in the north-west Indian Ocean, the Carlsberg Ridge is "probably the best ridge in the world". So say excited scientists from Southampton Oceanography Centre who have just found the first evidence of hydrothermal activity in this previously unexplored area of a volcanic mid-ocean ridge. The team aboard... view more... (2003-07-29)
U of Minnesota-led study reveals mysteries of deep-sea nutrients
Iron dust, the rare but necessary nutrient for most life, can not only be washed into the ocean from rivers or blown out to sea, but it can bubble up from the depths of the ocean floor, a new study led by a University of Minnesota scientist shows. view more (2009-02-09)
Scientists break record by finding northernmost hydrothermal vent field
Well inside the Arctic Circle, scientists have found black smoker vents farther north than anyone has ever seen before. The cluster of five vents - one towering nearly four stories in height - are venting water as hot as 570 F. view more (2008-07-25)
At an underwater volcano, evidence of man's environmental impact
Scientists studying hydrothermal vents, those underwater geysers that are home to bizarre geological structures and unique marine species, have discovered something all too familiar: pollution. view more (2006-08-02)
Iron on its route to the sea-floor: A new path
Iron dust, the rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or--a surprising new study finds--float up from the sea floor in the material spewed from hydrothermal vents. view more (2009-02-09)
Shining a light on deep-sea vents: Science meets policy
Scientists first discovered undersea hot springs, known as hydrothermal vents, nearly 30 years ago. These vents, which are among the world's most extreme ecosystems, are found along the ocean ridge, 40,000 miles of underwater mountain range that zig-zags throughout the world's ocean basin. view more (2006-02-21)
News Release : Carbon Acts Like Rustoleum Around Hydrothermal Vents
The cycling of iron throughout the oceans has been an area of intense research for the last two decades. Oceanographers have spent a lot of time studying what has been affectionately labeled the Geritol effect ever since discovering that the lack of iron is a reason why phytoplankton grow lackadaisically in some of the most nutrient-rich surface... view more...

Bacteria 'Feed' on Earth's Ocean-Bottom Crust
Seafloor bacteria on ocean-bottom rocks are more abundant and diverse than previously thought, appearing to "feed" on the planet's oceanic crust, according to results of a study reported in this week's issue of the journal Nature. view more (2008-05-29)
New deep-sea hydrothermal vents, life form discovered
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 (NSF) to explore the Pacific Ocean floor off Costa Rica. view more (2007-04-20)
Deep sea expedition sets sail
Setting sail on the Pacific, a University of Delaware-led research team has embarked on an extreme adventure that will find several of its members plunging deep into the sea to study hydrothermal vents on the ocean floor. view more (2008-11-11)

Genetic adaptations key to microbe's survival in challenging environment
The genome of a marine bacterium living 2,500 meters below the ocean's surface is providing clues to how life adapts in extreme thermal and chemical gradients, according to an article published Feb. 6 in the journal PLoS Genetics, an open-access publication published by the Public Library of Science. view more (2009-02-11)
Volcanic plumbing dictates development of deep-sea hydrothermal vents
After years of results that repeatedly dogged him, University of Oregon geologist Douglas R. Toomey decided to follow the trail of data surfacing from the Pacific Ocean. In doing so, he and his collaborators may have altered long-held assumptions involving plate tectonics on the ocean floor. view more (2007-03-22)
Hydrothermal vents: Hot spots of microbial diversity
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 (Marine Biological Laboratory) and University of Washington's Joint Institute for the Study of Atmosphere and Ocean. view more (2007-10-05)
New undersea vent suggests snake-headed mythology
A new "black smoker" — an undersea mineral chimney emitting hot, iron-darkened water that attracts unusual marine life — has been discovered at about 8,500 feet underwater by an expedition currently exploring a section of volcanic ridge along the Pacific Ocean floor off Costa Rica. view more (2007-04-18)
Scientists Discover First Seafloor Vents on Ultraslow-Spreading Ridge
Scientists have found one of the largest fields of seafloor vents gushing super-hot, mineral-rich fluids on a mid-ocean ridge that, until now, remained elusive to the ten-year hunt to find them. view more (2007-04-16)
Some like it hot: Worms at deep-sea vents favor a fiery 45-55°C
Scientists have found that worms dwelling at deep-sea hydrothermal vents opt for temperatures of 45-55 degrees Celsius (113-131 degrees Fahrenheit) when given a choice of conditions, giving them the highest thermal preference of any animal studied to date. view more (2006-04-14)
Quakes under Pacific floor reveal unexpected circulatory system
Zigzagging some 60,000 kilometers across ocean floors, earth's system of mid-ocean ridges plays a pivotal role in many workings of the planet, from its plate-tectonic movements to heat flow from the interior, and the chemistry of rock, water and air. view more (2008-01-10)
Deep-sea rocks point to early oxygen on Earth
Red jasper cored from layers 3.46 billion years old suggests that not only did the oceans contain abundant oxygen then, but that the atmosphere was as oxygen rich as it is today, according to geologists. view more (2009-03-25)
