U. of Colorado study shows massive CO2 burps from ocean to atmosphere at end of last ice age
A University of Colorado at Boulder-led research team tracing the origin of a large carbon dioxide increase in Earth's atmosphere at the end of the last ice age has detected two ancient "burps" that originated from the deepest parts of the oceans. view more (2007-05-11)
Has the mystery of the Antarctic ice sheet been solved?
A team of scientists from Cardiff University's School of Earth and Ocean Sciences and Amgueddfa Cymru - National Museum Wales travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet. view more (2008-02-28)
Scientists Detect Melting of Antarctic Ice Shelf
A giant ice shelf the size of Scotland is melting rapidly in warm Antarctic waters, a report in SCIENCE will reveal today. Thinning of the Larsen Ice Shelf - vast sections of which collapsed catastrophically during the 1990's - was discovered by scientists at the University of Cambridge, University College London, University of Bristol and the... view more...

Discarded human debris threatens global biodiversity
Discarded human debris is encouraging colonization of exotic marine animals in the world`s oceans and threatening global biodiversity, particularly in the Southern Ocean. The findings, reported in this week`s NATURE, are based on a 10-year study of human litter (mostly plastic) washed ashore on 30 remote islands around the globe, from the Arctic... view more...

Human impacts on coral reefs of Northwestern Hawaiian islands revealed
Results of a new study shed light on how threats to the world's endangered coral reef ecosystems can be more effectively managed. view more (2009-04-08)
Global warming will reduce ocean productivity, marine life
A 10-year, satellite-based analysis has shown for the first time that primary biological productivity in the oceans-the growth of phytoplankton that forms the basis for the rest of the marine food chain-is tightly linked to climate change, and would be reduced by global warming. view more (2006-12-07)
Nitrogen fixation and phytoplankton blooms in the southwest Indian Ocean
Observations made by Southampton scientists help understand the massive blooms of microscopic marine algae - phytoplankton - in the seas around Madagascar and its effect on the biogeochemistry of the southwest Indian Ocean. view more (2009-08-17)
Genetics links whale to two different ocean basins
For the first time ever, a genetic study has followed a single humpback whale from one ocean basin to another, adding to traditional notions of the migratory patterns of these majestic marine mammals in the process. view more (2005-08-18)
Soil moisture and ocean salinity satellite ready for launch
A new European Earth observation satellite will be launched in the early hours of Monday morning (2 November 2009) from the Plesetsk Cosmodrome in northern Russia. view more (2009-10-30)
Call for network to monitor Southern Ocean current
In a commentary published in the journal Science today, Dr John Church of the Antarctic Climate and Ecosystem Cooperative Research Centre and CSIRO, through the Wealth from Oceans Flagship, said a Southern Hemisphere observing network is needed to complement a network of moorings now spanning the North Atlantic Ocean. view more (2007-08-20)
Europa does the wave to generate heat
One of the moons in our solar system that scientists think has the potential to harbor life may have a far more dynamic ocean than previously thought. view more (2008-12-12)
Southern Ocean could slow global warming
The Southern Ocean may slow the rate of global warming by absorbing significantly more heat and carbon dioxide than previously thought, according to new research. view more (2006-12-06)
Outflow from World's Largest River - the Amazon - Powers Atlantic Ocean Carbon
Nutrients from the Amazon River's outflow spread well beyond the continental shelf and drive carbon cycling in the tropical ocean, say scientists who conducted a multi-year study. They will publish their results this week online in the journal Proceedings of the National Academy of Sciences (PNAS). view more (2008-07-23)
Slowdown in tropical Pacific flow pinned on climate change
The vast loop of winds that drives climate and ocean behavior across the tropical Pacific has weakened by 3.5% since the mid-1800s, and it may weaken another 10% by 2100. view more (2006-05-04)
University of Copenhagen
Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. In shallow coastal regions, these zones can be caused by runoff of excess fertilizers from farming. view more (2009-01-26)
Acid Rain Has a Disproportionate Impact on Coastal Waters
The release of sulfur and nitrogen into the atmosphere by power plants and agricultural activities plays a minor role in making the ocean more acidic on a global scale, but the impact is greatly amplified in the shallower waters of the coastal ocean, according to new research by atmospheric and marine chemists. view more (2007-09-10)
Toxic to aliens -- but key to health of planet
Scientists at the University of Leicester are using an ingredient found in common shampoos to investigate how the oxygen content of the oceans has changed over geologically recent time. view more (2008-06-19)
New findings blow a decade of assumptions out of the water
The Atlantic Ocean doesn't receive the mother lode of fixed nitrogen, the building block of life, after all. Instead, comparing fathom for fathom, the Pacific and Indian oceans experience twice the amount of nitrogen fixing as the Atlantic. view more (2007-01-11)
Can ancient rocks yield clues about catastrophes like Hurricane Katrina?
Hurricane Katrina and other natural catastrophes in recent years have shown how vulnerable mankind is in the face of nature. view more (2005-09-08)
Without its insulating ice cap, Arctic surface waters warm to as much as 5 C above average
Record-breaking amounts of ice-free water have deprived the Arctic of more of its natural "sunscreen" than ever in recent summers. The effect is so pronounced that sea surface temperatures rose to 5 C above average in one place this year, a high never before observed, says the oceanographer who has compiled the first-ever look at average... view more...
