[geo] CO2 effects on plankton

[Rau, Greg]

In situ studies predict major changes to plankton community structure and C 
cycling/storage as CO2 increases. As an aside, interesting to ponder the 
politics/ethics of adding CO2 versus iron to ocean experiments at this scale.

As the climate changes and oceans’ acidity increases, tiny plankton seem set 
to succeed. An international team of marine scientists has found that the 
smallest plankton groups thrive under elevated carbon dioxide (CO2) levels. 
This could cause an imbalance in the food web as well as decrease ocean CO2 
uptake, an important regulator of global climate. The results of the study, 
conducted off the coast of Svalbard, Norway, in 2010, are now compiled in a 
special issue published in Biogeoscienceshttp://www.biogeosciences.net/, a 
journal of the European Geosciences Union.

“Time and [time] again the tiniest plankton benefits from the surplus CO2, they 
produce more biomass and more organic carbon, and dimethyl sulphide production 
and carbon export are decreasing,”
