Short-circuit found in ocean circulation
Scientists have discovered how ocean circulation is working in the current that flows around Antarctica by tracing the path of helium from underwater volcanoes. The details are published in Nature this week. view more (2007-05-11)
Salty oceans provide early warning for climate change
Monitoring the saltiness of the ocean water could provide an early indicator of climate change. Significant increases or decreases in salt in key areas could forewarn of climate change in 10 to 20 years time. view more (2007-06-11)
Geologists Discover New Way of Estimating Size and Frequency of Meteorite Impacts
Scientists have developed a new way of determining the size and frequency of meteorites that have collided with Earth. view more (2008-04-14)
Metagenomics of the deep Mediterranean
Metagenomics is a revolutionary approach to study microbes. Rather than isolating pure cultures, the power of high-throughput sequencing is applied directly to environmental samples to obtain information about the genomes of the prokaryotic cells present in a specific habitat studied. view more (2007-09-19)
The dawn of deep ocean mining
We're on the brink of the era of deep ocean mining, says a global pioneer in the study of sea floor mineral deposits. view more (2006-02-21)
Asphalt flows from deep-sea volcanoes
New kind of volcano discovered in the Gulf of Mexico Underwater volcanoes that spew asphalt instead of lava: they were discovered in the Gulf of Mexico during an expedition of the research vessel SONNE, led by Prof. Gerhard Bohrmann of the DFG Research Center Ocean Margins. On these volcanoes the multinational team of scientists encountered a... view more... (2004-05-17)
Invisible waves shape continental slope
A class of powerful, invisible waves hidden beneath the surface of the ocean can shape the underwater edges of continents and contribute to ocean mixing and climate, researchers from The University of Texas at Austin have found. view more (2008-07-01)
British oceanographers find 'smoking' submarine volcano in the Indian Ocean
At over three thousand metres down in the north-west Indian Ocean, the Carlsberg Ridge is "probably the best ridge in the world". So say excited scientists from Southampton Oceanography Centre who have just found the first evidence of hydrothermal activity in this previously unexplored area of a volcanic mid-ocean ridge. The team aboard... view more... (2003-07-29)
Antarctic krill provide carbon sink in Southern Ocean
New research on Antarctic krill (Euphausia superba), a shrimp-like animal at the heart of the Southern Ocean food chain, reveals behaviour that shows that they absorb and transfer more carbon from the Earth's surface than was previously understood. view more (2006-02-07)
32-mile cable installed for first deep-sea observatory
Oceanographers have completed an important step in constructing the first deep-sea observatory off the continental United States. Workers in the multi-institution effort laid 32 miles (52 kilometers) of cable along the Monterey Bay sea floor that will provide electrical power to scientific instruments, video cameras, and robots 3,000 feet (900... view more...

X-rays use diamonds as a window to the center of the Earth
Diamonds from Brazil have provided the answers to a question that Earth scientists have been trying to understand for many years: how is oceanic crust that has been subducted deep into the Earth recycled back into volcanic rocks? view more (2008-08-13)
Indian eddies supply Atlantic Ocean with warm water
Water from the Indian Ocean does not reach the South Atlantic Ocean continuously, but in separate packages. These are called Agulhas eddies, after the current along the east coast of Southern Africa where they originate from. view more (2005-10-11)
Marine researchers explore sediment highways
A European team of researchers has demonstrated that sediment is transported to the deep sea via canyons in the seabed. The sediment accumulates in the head of the submarine canyons. At the end of the canyons, mud avalanches disperse into the deep sea. Scientists from the Netherlands Institute for Sea Research (NIOZ) presented their findings at an... view more... (2002-04-18)
Meteor no longer prime suspect in great extinction
The greatest mass extinction in Earth's history also may have been one of the slowest, according to a study that casts further doubt on the extinction-by-meteor theory. view more (2007-10-25)
Low oxygen and molybdenum in ancient oceans delayed evolution of life by 2 billion years
A deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth by nearly two billion years, a study led by UC Riverside biogeochemists has found. view more (2008-03-27)
A robot for building planes
Fatronik Technological Centre has put the finishing touches to the development of a portable climbing robot capable of carrying out precision operations and originally designed for the aeronautics sector. view more (2005-04-13)
Aquatic creatures mix ocean water
Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El Niño on our weather. Modern ocean models primarily incorporate the effects of winds and tides. However, they do not generally take into account the mixing generated by swimming animals. view more (2009-11-23)
Deciphering Arctic climate puzzles - New findings from the Arctic Coring Expedition
An international team of scientists is currently evaluating sediment cores collected during the Arctic Coring Expedition, ACEX, conducted under the auspices of the Integrated Ocean Drilling Program (IODP). ACEX, conducted in August and September this year, is an exploration success story. At a press conference in the University of Bremen, Germany,... view more... (2004-11-17)
Global warming doubles rate of ocean rise
Global ocean levels are rising twice as fast today as they were 150 years ago, and human-induced warming appears to be the culprit. view more (2005-11-28)
Climate variability impacts the deep sea
Deep-sea ecosystems occupying 60% of the Earth's surface could be vulnerable to the effects of global warming warn scientists writing in the Proceedings of the National Academy of Sciences. view more (2009-11-03)
