Latest Hydrothermal vent Stories
A research team led by the Woods Hole Oceanographic Institution (WHOI) has uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean.
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.
Two recent discoveries in astrobiology challenge many of our assumptions about an integrated biological community on Earth.
Arizona State University geochemist Lynda Williams and her colleagues have discovered that certain clay minerals under conditions at the bottom of the ocean may have acted as incubators for the first organic molecules on Earth.
Dr. Pan Conrad is on a quest. Her search for signs of life in extreme environments has taken the JPL astrobiologist from the icy realms of the Arctic and the dry valleys of Antarctica to the scorching sands of Death Valley, California. The hunt landed Conrad at the bottom of the ocean with Oscar-winning director James Cameron and a role in his film "Aliens of the Deep."
A team of researchers has found evidence of photosynthesis taking place deep within the Pacific Ocean. The team found a bacterium that is the first photosynthetic organism that doesn't live off sunlight but from the dim light coming from hydrothermal vents nearly 2,400 meters (7,875 feet) deep in the ocean.
The discovery of green sulfur bacteria living near hydrothermal vents has major implications for where photosynthesis happens and where life may reside.
Leaps in technology have made the darkest reaches of the sea much easier to explore, necessitating new rules to govern the precious resources of the deep, researchers said in a report.
New keys to understanding the evolution of life on Earth may be found in the microbes and minerals vented from below the ocean floor, say scientists at the University of California, Santa Barbara.
Film director and exploration enthusiast James Cameron (Titanic, Aliens) gave Stanford graduate student Kevin Hand a chance to search for "alien" life close to home -- a mere 2 miles below the ocean surface -- as part of Cameron's IMAX documentary, Aliens of the Deep, which opens today.
The Pompeii worm (Alvinella pompejana) is a species of polychaete worm, or bristle worm that is only found in the Pacific Ocean. It resides at hydrothermal vents, making it an extremophile, and was first discovered French marine biologists of the coat of the Galapagos Islands in the 1980s. It was described by Lucien Laubier and Daniel Desbruyeres as a deep-sea polychaete that could withstand extreme amounts of heat. The Pompeii worm can reach an average length of up to five inches and is...
Bathymodiolus thermophilus is a species of large, deepwater mussel, a marine bivalve mollusk belonging to the family Mytilidae. The species was discovered at abyssal depths when submersible vehicles began exploring the deep ocean. It occurs on the sea bed, frequently in large numbers, close to hydrothermal vents where hot, sulphur-rich water wells up through the floor of the Pacific Ocean. This is a very large mussel with a dark brown periostracum, growing to a length of about 8 inches....
