he Deep-sea Drilling Vessel CHIKYU successfully completed riser drilling operations on Aug. 31, for IODP Expedition 319, Stage 2 of the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE). view more (2009-09-08)
Scientists obtain rocks moving into seismogenic zone
An international group of scientists aboard the Deep-Sea Drilling Vessel CHIKYU, operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for the Integrated Ocean Drilling Program (IODP), return from a 40-day scientific expedition off the shore of the Kii Peninsula, Japan on Oct. 10, 2009. view more (2009-10-12)
2000 meters deep in Antarctic ice
European ice core drilling project at Kohnen station retrieves old ice for climate research. At the Kohnen station operated by Alfred-Wegener-Institute for Polar- and Marine Research, Bremerhaven, the international drilling team reached a depth of 2000 meters on January 7 at 0210 hours. The ice from that depth is about 100.000 years old and yields... view more... (2004-01-08)
Scientists launch deep-sea scientific drilling program to study volatile earthquake zone
Today, the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) gets underway, with the Japanese drilling vessel Chikyu departing from Shingu Port with scientists aboard, all ready to log, drill, sample, and install monitoring instrumentation in one of the most active earthquake zones on Earth. view more (2007-09-21)
Ice and a slice of climate history
The first 40 million years of Arctic climate history was recovered from beneath the Arctic sea floor yesterday (Monday 23 August). view more (2004-08-24)
Aurora Borealis breaks new grounds - and old ice
It can crush ice sideways and stay precisely on station to an accuracy of a metre. It can drill a hole 1,000 metres deep into the seabed while floating above 5,000 metres of ocean and it can generate 55 megawatts of power. So far, Aurora Borealis is the most unusual ship that has never been built, and it represents a floating laboratory for... view more... (2007-12-03)
Stanford researchers say living corals thousands of years old hold clues to past climate changes
Using radiocarbon dating and samples of deep-sea corals snipped from the floor of the Pacific Ocean by a submersible, researchers from Stanford and Lawrence Livermore National Laboratory have discovered that deep-sea corals growing off Hawaii are much older than previously thought-some as old as 4,000 years. view more (2008-02-15)
Environmentally friendly drilling with computers
A new doctoral dissertation from Lule'å University of Technology in Sweden deals with processes, systems, and problems in the use of a newly developed, environmentally friendly rock drilling method. The method, which is patented for the entire world, uses only water both to run the drill and to flush out the crushed rock. view more (2004-12-20)
New research to help guarantee future of oil supplies
Scientists at the University of Liverpool are working with leading oil companies to further understanding of the nature of oil and gas reservoirs within deeply buried submarine channels. view more (2006-01-05)
Sunlight has more powerful influence on ocean circulation and climate than North American ice sheets
A study reported in today's issue of Nature disputes a longstanding picture of how ice sheets influence ocean circulation during glacial periods. view more (2008-11-07)
Nature publishes new evidence about the deep biosphere written by biogeoscientists
Biogeoscientists show evidence of 90 billion tons of microbial organisms-expressed in terms of carbon mass-living in the deep biosphere, in a research article published online by Nature, July 20, 2008. view more (2008-07-21)
U of Minnesota-led study reveals mysteries of deep-sea nutrients
Iron dust, the rare but necessary nutrient for most life, can not only be washed into the ocean from rivers or blown out to sea, but it can bubble up from the depths of the ocean floor, a new study led by a University of Minnesota scientist shows. view more (2009-02-09)
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)
Geophysical Research Letters European Highlights - 1 August 2001
Highlights 4. Deep water has many sources Hellmer and Beckmann ["The Southern Ocean: A Ventilation Contributor with Multiple Sources"] use a coupled ocean/ice-shelf model to determine the location and rate of Antarctic Bottom Water (AABW) formation. Their results suggest that the Atlantic and Indian-Pacific are equal contributors but produce... view more... (2001-07-16)
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 rapid formation of ice in Antarctica. Carrie Lear,... 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 members, helicopter pilots and technical staff,... 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 the surface. 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)
