Scientists discover giant carbon sink in deep ocean

August 1, 2012CLIMATE The world’s oceans are known to be carbon sinks, but the process that draws CO2 from the air down into the deep ocean hasn’t been documented. Until now. A team of British and Australian scientists have identified huge plunging currents – as much as 1,000 kilometers wide – that appear to be key to the process of storing CO2 in the deep ocean. Those currents, the researchers say, are the result of local eddies (resulting from a combination of wind, currents, and massive whirlpools) that create localized pathways down from the surface. Published in Nature Geoscience, the research used Argo robotic floats to help explore ocean dynamics up to 2 Km down, along with analysis of temperature, salinity, and pressure data. The Argo floats – 80 in total – were deployed in 2002 and collected data for ten years as the basis of this research. CTD (conductivity, density and temperature) profilers were also used to collect data at depths of up to 7 Km, the researchers say. The Southern Ocean is an important carbon sink (at least for those who believe that anthropogenic carbon emissions are driving climate change – a list which now includes formerly skeptical scientist Richard Muller). It’s calculated to take up as much as 40 percent of the CO2 absorbed by oceans (which in turn soak up a quarter of total annual emissions). The British Antarctic Survey’s Dr. Jean-Baptiste Sallée says the study means scientists are “better placed to understand the effects of changing climate and future carbon absorption by the ocean.” Collaborator Dr Richard Matear of Australia’s CSIRO noted that while observations had measured the CO2 found in the deep ocean, it’s important to identify the pathways used to get there – particularly since significant climate change could change the behavior of those processes. Southern Ocean currents are also affected by other atmospheric changes like ozone depletion, which could also change its effectiveness as a carbon sink. –Register

    I learn something new everyday reading your articles Alvin. Thanks.

    This can’t be good news for aquatic life can it?

    i wander if this means the ocean floor should have more chance of large diamonds seeing how its such a carbon trap, and being so far below the ocean there is tremendous amounts of pressure on it…hmm…maybe i need to go deep deep deep sea diving…

    This is God and his wonderful design and creation to maintain this planet suitable for us, yet the atheist will deny it as coincidence despite overwhelming evidence. This is proof that we are deeply envious of God and want to deny his existence no matter what and that is why we have been sent to the material world in the first place. Because we became envious of God and wanted to forget Him and try to enjoy separate from God.
