Arctic Coring Expedition Continues to Yield New Clues About Climate Change
For the second time in as many months, the IODP Arctic Coring Expedition (ACEX) is making news with new analysis of ocean-floor sediments.   view more (2006-08-10)

Cooling Off Periods
Research by a team of Cambridge scientists has provided new clues about the first dramatic cooling of the Earth's climate 34 million years ago. The team, based at the University of Cambridge's Department of Earth Sciences said that ocean temperature drops were apparently not responsible for the... view more (2000-01-12)

Twentieth "Polarstern" expedition to Arctic is drawing to a close
On October 3rd, the German research vessel "Polarstern" of the Alfred Wegener Institute for Polar and Marine Research will return to Bremerhaven from its 20th arctic expedition. During the last leg of the voyage, 44 scientists from Germany, Russia and South Korea, supported by crew... view more (2004-10-04)

IODP Tahiti Sea Level Expedition Examines History of Global Sea Level Change, El Ni√ħo Events
Scientists from nine nations have set sail for the Integrated Ocean Drilling Program (IODP) Tahiti Sea Level Expedition, a research expedition initiated to investigate global sea level rise since the last glacial maximum, approximately 23,000 years ago.   view more (2005-10-10)

Global warming can trigger extreme ocean, climate changes
Newly published research results provide evidence that global climate change may have quickly disrupted ocean processes and lead to drastic shifts in environments around the world.   view more (2006-01-05)

Ocean's 'twilight zone' may be a key to understanding climate change
A major study sheds new light on the role of carbon dioxide once it's transported to the oceans' depths. The research indicates that instead of sinking, carbon dioxide is often consumed by animals and bacteria and recycled in the "twilight zone," a dimly lit area 100 to 1,000 meters below... view more (2007-04-30)

ODP scientists say no large Northern Hemisphere ice sheets 41 million years ago
New research to test global ice volume approximately 41.6 million years ago shows that ice caps at this time, if they existed at all, would have been small and easily accommodated on Antarctica.   view more (2007-08-23)

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)

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)

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... view more (2004-05-17)

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... 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)

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)

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... view more (2007-04-09)

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)

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... 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)

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)

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)

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... view more (2004-11-17)

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)
