Catastrophic 'lake burst' chills climate
Ocean circulation changes during the present warm interglacial were more extensive than previously thought, according to new research by the University of East Anglia (UEA) and Cardiff University.   view more (2006-06-30)

Melting of the Greenland ice cap may have consequences for climatic change
According to two international-research studies on the last ice age, studies with the participation of Dr Rainer Zahn, research professor in the ICREA at the UAB Institute of Environmental Science and Technology (ICTA), before the great ice sheets of the Arctic Ocean began to melt, early sporadic... view more (2007-05-08)

Food source threatened by carbon dioxide
Carbon dioxide increasing in the atmosphere may affect the microbial life in the sea, which could have an impact on a major food source, warned Dr Ian Joint at a Science Media Centre press briefing today.   view more (2007-12-11)

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... view more (2001-07-16)

Biodiversity hotspots, centres of endemicity, and the conservation of coral reefs
Coral reefs are renowned for their spectacularly high biodiversity, yet there is widespread concern for their future in the face of threats from land-clearing, over-fishing and global warming. A new study published in Ecology Letters by Australian scientists - Terry Hughes, David Bellwood and Sean... view more (2002-10-30)

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)

Expedition allows teachers to participate in polar research
What better way to engage students in science than to apply lessons learned from fieldwork? This is the philosophy of Alaska teachers participating in the Arctic Expedition for K-12 Teachers, a program organized by the International Arctic Research Center (IARC) at the University of Alaska... view more (2006-09-14)

Ocean satellite launch critical to Australian science
A new earth observing satellite being launched in California today will help guide future Australian ocean and climate science.   view more (2008-06-23)

Scientists Find Good News About Methane Bubbling Up From the Ocean Floor Near Santa Barbara
Methane, a potent greenhouse gas, is emitted in great quantities as bubbles from seeps on the ocean floor near Santa Barbara.   view more (2007-12-21)

NASA data show some African drought linked to warmer Indian Ocean
A new study, co-funded by NASA, has identified a link between a warming Indian Ocean and less rainfall in eastern and southern Africa. Computer models and observations show a decline in rainfall, with implications for the region's food security.   view more (2008-08-06)

Declining sharks
The transformation of terrestrial and coastal ecosystems by humans is well known, but only recently have the impacts of anthropogenic forces in the open ocean been recognized. In particular, intense exploitation by industrial fisheries is rapidly changing oceanic ecosystems by drastically reducing... view more (2004-02-05)

NASA co-sponsors ocean voyage to probe climate-relevant gases
More than 30 scientists will embark next week on a research mission to the Southern Ocean. Researchers will battle the elements to study how gases important to climate change move between the atmosphere and the ocean under high winds and seas.   view more (2008-02-22)

Scientists derive bottom-up air-sea momentum transfer under major hurricane
Scientists at the Naval Research Laboratory-Stennis Space Center (NRL-SSC) have directly derived the air-sea momentum exchange at the ocean interface using observed ocean currents under Hurricane Ivan and determined that it decreases when winds exceed 32 meters per second.   view more (2007-03-29)

The striking deep current reversal in the tropical Pacific Ocean
The ocean's immense heat storage capacity means that it has a dominant role in the regulation of heat exchange and of the Earth's climate. And it is the ocean's currents that drive thermal exchanges between ocean and atmosphere and contribute to climate balance.   view more (2006-11-14)

Changes in Ocean Circulation Could Lead To Rapid Regional Sea Level Change
One of the major consequences of future ocean circulation changes would be sea level change. This is shown in a new study by scientists from the Potsdam Institute for Climate Impact Research in Germany which was published in the recent issue of "Climate Dynamics". They investigated the scenario of... view more (2005-04-04)

Future climate change in North-Western Europe may come as a shock
North-Western Europe could be in for some sudden climatic surprises in the future, say scientists speaking at the launch of a new book on global environmental change*. North-Western Europe is kept warm by an ocean current known as the North Atlantic Current, an extension of the Gulf Stream which... view more (2004-01-16)

Climate kick from the Southern Ocean
This much was already known: in the closing phase of the last ice age the Southern Hemisphere began warming first. As a result, the Antarctic sea ice melted. It was at least a thousand years later - as evidenced by investigations of Greenland ice cores - that the high northern latitudes began to... view more (2003-07-29)

Ocean temperature predicts spread of marine species
Scientists can predict how the distance marine larvae travel varies with ocean temperature - a key component in conservation and management of fish, shellfish and other marine species - according to a new study from the University of North Carolina at Chapel Hill.   view more (2006-12-26)

Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today.   view more (2007-12-11)

Deft diving turtle tactics
How do turtles survive long trips across the ocean? At the Society for Experimental Biology conference on Friday 12 April Ms Corinne Martin (University of Wales Swansea) will present evidence of energy-saving diving patterns adopted by green turtles to survive long ocean trips. The turtles breed at... view more (2002-04-04)

Oceans turning to acid from rise in CO2
A report issued by the Royal Society in the U.K. sounds the alarm about the world's oceans. "If CO2 from human activities continues to rise, the oceans will become so acidic by 2100 it could threaten marine life in ways we can't anticipate," commented Dr. Ken Caldeira, co-author of the... view more (2005-07-01)

Geologists: Opening of passage may be tied to Antarctic cooling
Ancient fish teeth are yielding clues about when Antarctica became the icy continent it is today, highlighting how ocean currents affect climate change.   view more (2006-04-21)

Snowball Antarctica - early Drake passage opening led to global change
New results shed light on how Antarctica became the icy, barren continent that we know today.   view more (2005-08-31)

Scientists discover new life forms in the Arctic Ocean
An international team of scientists including Université Laval biologist Connie Lovejoy has discovered new life forms in the Arctic Ocean. The team's findings are reported in the January 12 edition of the journal Science.   view more (2007-01-12)

NASA study solves ocean plant mystery
A NASA-sponsored study shows that by using a new technique, scientists can determine what limits the growth of ocean algae, or phytoplankton, and how this affects Earth's climate.   view more (2006-09-01)
