Researchers establish common seasonal pattern among bacterial communities in Arctic rivers
New research on bacterial communities throughout six large Arctic river ecosystems reveals predictable temporal patterns, suggesting that scientists could use these communities as markers for monitoring climate change in the polar regions.   view more (2009-11-24)

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)

Oceans' uptake of manmade carbon may be slowing
The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air.   view more (2009-11-19)

A glimpse at the Earth's crust deep below the Atlantic
Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor, says geologist Dr Bram Murton of the National Oceanography Centre, Southampton.   view more (2009-11-13)

How much water does the ocean have?
The calculation of variations in the sea level is relatively simple. It is by far more complicated to then determine the change in the water mass.   view more (2009-11-13)

Earth's early ocean cooled more than a billion years earlier than thought: Stanford study
The scalding-hot sea that supposedly covered the early Earth may in fact never have existed, according to a new study by Stanford University researchers who analyzed isotope ratios in 3.4 billion-year-old ocean floor rocks.   view more (2009-11-12)

A bubbling ball of gas
The Sun is a bubbling mass. Packages of gas rise and sink, lending the sun its grainy surface structure, its granulation. Dark spots appear and disappear, clouds of matter dart up - and behind the whole thing are the magnetic fields, the engines of it all.   view more (2009-11-12)

Cave Study Links Climate Change to California Droughts
California experienced centuries-long droughts in the past 20,000 years that coincided with the thawing of ice caps in the Arctic.   view more (2009-11-11)

Antarctica glacier retreat creates new carbon dioxide store
Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula.   view more (2009-11-10)

Tags reveal white sharks have neighborhoods in the north Pacific, say Stanford researchers
The white shark may be the ultimate loner of the ocean, cruising thousands of miles in a solitary trek, but a team of researchers has discovered that the sharks have maintained such a consistent pattern of migration that over tens of thousands of years the white sharks in the northeastern Pacific Ocean have separated themselves into a population... view more...

Iron controls patterns of nitrogen fixation in the Atlantic
Scientists including researchers from the National Oceanography Centre, Southampton and the University of Essex have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic.   view more (2009-11-03)

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)

African Desert Rift Confirmed as New Ocean in the Making
In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent pulled apart, but the claim was controversial.   view more (2009-11-03)

North Atlantic Fish Populations Shifting as Ocean Temperatures Warm
About half of 36 fish stocks in the Northwest Atlantic Ocean, many of them commercially valuable species, have been shifting northward over the last four decades, with some stocks nearly disappearing from U.S. waters as they move farther offshore, according to a new study by NOAA researchers.   view more (2009-11-03)

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)

Ocean acidification may contribute to global shellfish decline
Relatively minor increases in ocean acidity brought about by high levels of carbon dioxide have significant detrimental effects on the growth, development, and survival of hard clams, bay scallops, and Eastern oysters, according to researchers at Stony Brook University's School of Marine and Atmospheric Sciences.   view more (2009-10-27)

Arctic Sediments Show That 20th Century Warming Is Unlike Natural Variation
The possibility that climate change might simply be a natural variation like others that have occurred throughout geologic time is dimming, according to evidence in a Proceedings of the National Academy of Sciences paper published today.   view more (2009-10-26)

Queen's scientists on international team discover 'ecologically unique' changes in Arctic lake
Queen's University biologists are part of an international research team whose discovery of a rare sediment core in a remote Arctic lake provides compelling evidence of unprecedented environmental changes occurring over the past few decades.   view more (2009-10-20)

Arctic lake sediments show warming, unique ecological changes in recent decades
An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change, according to a new study led by the University of Colorado at Boulder.   view more (2009-10-20)

Arctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide.   view more (2009-10-15)
