Dr. Craig R. Smith, oceanography professor at the University of Hawai'i at Mānoa, recently published a paper in Marine Ecology Progress Series titled, "Biogeochemistry of a deep-sea whale fall: sulfate, reduction, sulfide efflux and methanogenesis."The research by Smith and collaborators is the first detailed study of microbial processes at a deep-sea whale fall. The work evaluated the biogeochemical effects of a 30-ton whale carcass deployed at 1,675 mile depth for...

University of Colorado scientists detect microscopic life near 19,850 feet Gases rising from deep within the Earth are fueling the world's highest-known microbial ecosystems, which have been detected near the rim of the 19,850-foot-high Socompa volcano in the Andes by a University of Colorado at Boulder research team. The new study shows the emission of water, carbon dioxide and methane from small volcanic vents near the summit of Socompa sustains complex microbial ecosystems new to science...

Researchers are exploring extreme conditions for life in a place not known for extremes. As little as 20 meters (66 feet) below the surface of Lake Huron, the third largest of North America's Great Lakes, peculiar geological formations"”sinkholes made by water dissolving parts of an ancient underlying seabed"”harbor bizarre ecosystems where the fish typical of the huge freshwater lake are rarely to be seen. Instead, brilliant purple mats of cyanobacteria"”cousins of microbes...

U.S. scientists say they have discovered iron dust can not only be carried to the ocean by rivers or blown to sea, but can also rise from the ocean floor. Researchers found iron dust -- the rarest nutrient for most marine life -- can float up from the sea floor in material spewed from hydrothermal vents. Scientists from the University of Southern California, University of Minnesota, Woods Hole Oceanographic Institution and Lawrence Berkeley National Laboratory took samples from the East...

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.The research focused on the bacterium Nautilia profundicola, a microbe that survives near deep-sea hydrothermal vents. Microorganisms that thrive at these geysers on the sea floor must adapt to...

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 waters. Just like humans, sometimes the ocean needs a dose of iron to function more effectively. It is well known that the hydrothermal vents lining...

A team of scientists led by the University of Minnesota has discovered that 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. The study, published in the journal Nature Geoscience, connects life at the surface to events occurring at extreme depths and pressures"”two worlds long assumed to have little interaction. Brandy Toner, an assistant professor in...

Discovery provides clues to how life thrives in extreme environments The genome of a marine bacterium living 2,500 meters below the ocean's surface is providing clues to how life adapts in extreme environments, according to a paper published Feb. 6, 2009, in the journal PLoS Genetics. The research focused on the bacterium Nautilia profundicola, a microbe that survives near deep-sea hydrothermal vents. It was found in a fleece-like lining on the backs of Pompeii worms, a type of tubeworm that...

Huge methane gas bursts on Mars appear to be caused by bacteria rather than volcanic activity, U.S. government scientists said Thursday. The researchers at NASA's Goddard Space Flight Center in Greenbelt, Md., did not say what bacteria created the methane, the principal component of natural gas. But their findings, published in the journal Science, suggest the possibility of present-day microbes living on the fourth planet from the sun, The New York Times reported. On Earth, bacteria known as...

Scientists say they have captured a live deep-sea fish and three shrimp species at a record depth of 2,300m on the hot vents of the Mid-Atlantic Ridge. A new trapping device has been developed that allows recovery of live animals under their natural pressure at greater depths than previously achieved. The researchers hope to be able to transfer the animals into an experimental lab to study their normal biology. "Pressurized recovery has been around for the past 30 years, but this is the...

Pompeii Worm, Alvinella pompejana
2014-01-12 00:00:00

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
2013-04-16 18:50:25

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....
