Deep in the ocean, a clam that acts like a plant
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. view more (2007-02-21)
Novel protein complex enables survival in hostile environment
Biswarup Mukhopadhyay and Eric Johnson from the Virginia Bioinformatics Institute at Virginia Tech have discovered a novel enzyme that represents an ancient detoxification system and provides a clue to the development of early metabolism on earth. view more (2005-11-17)
Study outlines eruption at undersea volcano
An international team of scientists has presented its findings from the first observations of the eruption of a submarine volcano that in 2004 and 2005 spewed out plumes of sulfur-rich fluid and pulses of volcanic ash 550 meters below the ocean's surface near the Mariana Islands northwest of Guam. view more (2006-05-25)
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)
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)
Richness of Marine Life is Under Threat
Future potential for the production of new wonder drugs - including anti-cancer agents - from marine animals and plants, is under threat according to biodiversity expert Professor Carlo Heip, speaking at the European marine science and ocean technology conference EurOCEAN 2004 in Galway, today. According to Professor Heip, marine biodiversity -... view more... (2004-05-11)
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)
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)
Foot-dragging Mars rover finds Yellowstone-like hot spring deposits
Deposits of nearly pure silica discovered by the Mars Exploration Rover Spirit in Gusev Crater formed when volcanic steam or hot water (or maybe both) percolated through the ground. view more (2008-05-23)
Undersea Vehicles to Study Formation of Gold and Other Precious Metals On the Pacific Ocean Floor
An international team of scientists will explore the seafloor near Papua New Guinea in the western Pacific Ocean later this month with remotely operated and autonomous underwater vehicles, investigating active and inactive hydrothermal vents and the formation of mineral deposits containing copper, gold and other commercially valuable minerals. view more (2006-07-17)
Meteor impacts: Life's jump starter?
Meteor impacts are generally regarded as monstrous killers and one of the causes of mass extinctions throughout the history of life. view more (2005-08-09)
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)
Giant Deep-Sea Tubeworm's Meal Ticket Comes in as a Skin Infection
Giant tubeworms found near hydrothermal vents more than a mile below the ocean surface do not bother to eat: lacking mouth and stomach, they stand rooted to one spot. view more (2006-05-22)
NASA-funded Robotic Sub Makes Final Dive To Reach Bottom of Earth's Deepest Sinkhole
Scientists this week begin the final leg of a five-year, NASA-funded mission to reach the bottom of Cenote Zacatón in Mexico, the world's deepest known sinkhole. view more (2007-05-16)
Discovering an ecosystem beneath a collapsed Antarctic ice shelf
The chance discovery of a vast ecosystem beneath the collapsed Larsen Ice Shelf will allow scientists to explore the uncharted life below Antarctica's floating ice shelves and further probe the origins of life in extreme environments. view more (2005-07-19)
Radioactive crystals help identify and date ore deposits
Reddish-brown crystals of a radioactive mineral called monazite can act as microscopic clocks that allow geologists to date rock formations that have been altered by the action of high-temperature fluids, a process that frequently leads to the formation of rich ore deposits. view more (2006-08-01)
Nuclear cannibals
Nuclear energy production must increase by more than 10 percent each year from 2010 to 2050 to meet all future energy demands and replace fossil fuels, but this is an unsustainable prospect. view more (2008-03-05)
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)
Scientists gain new insights into 'frozen' methane beneath ocean floor
An international team of scientists supported by the Integrated Ocean Drilling Program (IODP) has completed a unique research expedition aimed at recovering samples of gas hydrate, an ice-like substance hidden beneath the seafloor off Canada's western coast. view more (2005-11-01)
