Unseen Armies Of Viruses And Bacteria Battle In The Deep
2014-05-02 03:58:44

National Science Foundation More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war. Like pirates boarding a treasure-laden ship, the viruses infect bacterial cells to get the loot: tiny globules of elemental sulfur stored inside the bacterial cells. Instead of absconding with their prize, the viruses force the bacteria to burn their valuable sulfur...

Not so dirty: Methane Fuels Life In Pristine Chalk Rivers
2014-04-02 16:47:40

Queen Mary, University of London Scientists from Queen Mary University of London have found that naturally high concentrations of the greenhouse gas methane contributes to energy production in chalk rivers, in a new study published today in the journal Proceedings of the Royal Society B. Chalk rivers, found from Dorset to Cambridgeshire, sustain a diverse range of protected animals and plants, and are renowned globally for fly fishing, an industry worth more than £4M on the Rivers Test...

Methane Seeps Of The Deep Sea Are A Bacteria Feast For Lithodid Crabs

Helmholtz Centre for Ocean Research Kiel (GEOMAR) Photos and analyses reveal more about a highly specialized food web The bottom of the deep sea is largely deserted. Oases occur for example at cold seeps where water transports dissolved elements from the seabed: Specialized microbes convert methane and sulfate from sea water to hydrogen sulfide releasing carbon dioxide. Highly adapted bacteria, many of which live in symbiosis with worms and clams, use the hydrogen sulfide for their...

First Evidence Of Life Deep Under Oceanic Crust Realized
2013-03-15 12:56:53

Lee Rannals for redOrbit.com — Your Universe Online Scientists writing in the journal Science say they have found the first direct evidence of life in the deeply buried oceanic crust. Researchers on board the Integrated Ocean Drilling Program's (IODP) research vessel JOIDES Resolution drilled a water depth of 1.5 miles and hundreds of feet of sediment into the oceanic crust off the west coast of North America. After examining rock samples from this depth, they were able to uncover...

Rare Cold Volcanic Vent Discovered In Antarctic Waters
2013-02-07 10:51:55

April Flowers for redOrbit.com - Your Universe Online Scientists at the National Oceanography Centre (NOC), Southampton have discovered the location of an underwater volcanic vent in the Southern Ocean. In a study published this week in the journal PLOS ONE, the researchers describe how this vent, marked by a low-lying plume of shimmering water, differs from "classic" hydrothermal vents. The research group used the NOC´s high-resolution deep-towed camera platform SHRIMP to image...

Max Planck researchers discover hydrogen-powered symbiotic bacteria in deep-sea hydrothermal vent mussels The search for new energy sources to power mankind's increasing needs is currently a topic of immense interest. Hydrogen-powered fuel cells are considered one of the most promising clean energy alternatives. While intensive research efforts have gone into developing ways to harness hydrogen energy to fuel our everyday lives, a natural example of a living hydrogen-powered 'fuel cell' has...

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...
