Creatures Of The Abyss Invade Surface World

"Don't panic," Douglas Adams might have said. Author of the sci-fi novel Hitchhiker's Guide to the Galaxy, Adams advised "don't panic" whenever facing invaders. What Adams might not have known is that the inner space of the oceans conceals aliens every bit as resourceful as any that might lurk in outer space. "And now these deep-sea-dwellers have turned the tables on us," says Janet Voight, a biologist at the Field Museum of Natural History in Chicago. Voight and other scientists...

Deep Sea Animals Reach New Territory By Clinging Onto Submarines
2012-05-24 07:50:04

Marine scientists studying life around deep-sea vents have discovered that some hardy species can survive the extreme change in pressure that occurs when a research submersible rises to the surface. The team's findings, published in Conservation Biology, reveal how a species can be inadvertently carried by submersibles to new areas, with potentially damaging effects on marine ecosystems. After using the manned submersible Alvin to collect samples of species from the Juan de Fuca Ridge...

Image 1 - Hot Meets Cold At New Deep-Sea Ecosystem

Habitats overlap at Jaco Scar in depths off Costa Rica Decades ago, marine scientists made a startling discovery in the deep sea. They found environments known as hydrothermal vents, where hot water surges from the seafloor and life thrives without sunlight. Then they found equally unique, sunless habitats in cold areas where methane rises from seeps on the ocean bottom. Could vents and seeps co-exist in the deep, happily living side-by-side? No one thought so. Until now....

Researchers discover unknown species at juncture where hot and cold habitats collide Among the many intriguing aspects of the deep sea, Earth's largest ecosystem, exist environments known as hydrothermal vent systems where hot water surges out from the seafloor. On the flipside the deep sea also features cold areas where methane rises from "seeps" on the ocean bottom. It's extremely rare to find both habitat types intersecting in one place, but that's what researchers found and explored...

New evidence found for ecological succession in microbial communities on deep-sea hydrothermal vents Scientists at USC have uncovered evidence that even when hydrothermal sea vents go dormant and their blistering warmth turns to frigid cold, life goes on. Or rather, it is replaced. A team led by USC microbiologist Katrina Edwards found that the microbes that thrive on hot fluid methane and sulfur spewed by active hydrothermal vents are supplanted, once the vents go cold, by microbes...

Researchers Find New Species At World’s Hottest, Deepest Ocean Vents
2012-01-11 12:30:50

New research from an intrepid team of British oceanographers reveals that the world´s deepest submarine volcanic vents are also the hottest that scientists have yet discovered. Moreover, they appear to be teeming with a variety of previously unknown life forms. According to measurements made in a recent expedition, the mineral-rich water streaming out of volcanic jets at the bottom of the Cayman Trough reaches temperatures exceeding 840 degrees Fahrenheit. Located over 3 miles below...

Researchers Find New Species Around Antarctic Hot Springs

Oceanographers exploring some of the most remote deep-sea hot springs have discovered one distinct biological zone teeming with life that nobody ever knew existed. The discovery, located more than a mile down in the ocean just north of Antarctica, uncovered the most strikingly unique array of life forms found in decades, including thousands upon thousands of a particular crab species never seen before, as well new species of barnacle, anemone, snail and starfish. The assembly of living...

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...

Pyrite nanoparticles from hydrothermal vents provide a rich source of iron for deep sea life, according to new research published in the current issue of the journal Nature Geoscience. Bacteria and tiny plants living in the ocean need iron for energy and growth, but are without the ability to use natural sources such as leafy greens or red meat.  But scientists have found evidence that points to an iron source on the seafloor: tiny particles of pyrite, or fool's gold, from hydrothermal...

By studying the tolerance of marine invertebrates to a wide range of temperature and pressure, scientists are beginning to understand how shallow-water species could have colonized the ocean depths. Scientists believe that climate changes at various at various times during Earth's history caused extinctions of creatures living at bathyal (1,000"“4,000 meters) and abyssal (>4,000 m) depths. These extinctions were apparently followed by re-colonization of the deep sea by shallow-water...
