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 Find New Species At World’s Hottest, Deepest Ocean Vents

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...

Giant Amoebas Found Deep in Mariana Trench

During a summer expedition to the deepest region on the planet, the Mariana Trench, a team of researchers and engineers witnessed a breed of giant amoebas known as xenophyophores living at depths that had never been recorded before, various media outlets reported over the weekend. The team, which consisted of scientists representing the Scripps Institution of Oceanography at UC San Diego and National Geographic engineers, used untethered landers known as dropcams, lights, and digital video...

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...

Scientists aboard the Royal Research Ship James Cook have discovered a new set of deep-sea volcanic vents in the chilly waters of the Southern Ocean.  The discovery is the fourth made by the research team in three years, which suggests that deep-sea vents may be more common in our oceans than previously thought. Using an underwater camera system, the researchers saw slender mineral spires three meters tall, with shimmering hot water gushing from their peaks, and gossamer-like white mats...

Hydrothermal vents may contribute more to the thermal budget of the oceans than previously assumed Scientists from the MARUM Center for Marine Environmental Sciences and the Max Planck Institute for Marine Microbiology in Bremen on board the German research vessel Meteor have discovered a new hydrothermal vent 500 kilometers south-west of the Azores. The vent with chimneys as high as one meter and fluids with temperatures up to 300 degrees Celsius was found at one thousand meters water depth...

Method included first use of Nereus hybrid vehicle in 'autonomous' mode The first expedition to search for deep-sea hydrothermal vents along the Mid-Cayman Rise has turned up three distinct types of hydrothermal venting, reports an interdisciplinary team led by Woods Hole Oceanographic Institution (WHOI) in this week's Proceedings of the National Academy of Sciences. The work was conducted as part of a NASA-funded effort to search extreme environments for geologic, biologic, and chemical...

An expedition partially funded by NASA, part of a program to search extreme environments for geological, biological and chemical clues to the origins and evolution of life, has discovered the deepest known hydrothermal vent in the world, nearly 5,000 meters (16,400 feet) below the surface of the western Caribbean Sea. The research will help extend our understanding of the limits to which life can exist on Earth and help prepare for future efforts to search for life on other planets. An...

A British scientific expedition has discovered the world's deepest undersea volcanic vents, known as 'black smokers', 3.1 miles (5000 meters) deep in the Cayman Trough in the Caribbean. Using a deep-diving vehicle remotely controlled from the Royal Research Ship James Cook, the scientists found slender spires made of copper and iron ores on the seafloor, erupting water hot enough to melt lead, nearly half a mile deeper than anyone has seen before. Deep-sea vents are undersea springs where...
