The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the ...
Earth Sciences | Read moreOptical properties of the Antarctic system and new radiation information
During the summer of 1997-1998, measurements of beam absorption and beam attenuation coefficients, and downwelling and upwelling irradiance were made in the Southern Ocean along a S-N transect at 6 de...

Polar 5 will be used in three research programmes in the season 2009/10 and it will logistically support the established Antarctic flight network DROMLAN (Dronning Maud Land Air Network) as well as va...
Earth Sciences | Read moreHow 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. A team of geodesists and oceanographers from the Univ...
Earth Sciences | Read moreControversial new climate change results
This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected. The results run contrary to a significant body of recent ...

In other words, a biological specimen determined by traditional DNA testing to be 100,000 years old may actually be 200,000 to 600,000 years old, researchers suggest in a new report in Trends in Genet...

The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years,...
