Is the ocean carbon sink sinking?

This article discusses the difficulties in using models to predict what the oceans are really all about with respect to CO2 and calcium carbonate, and why the southern ocean seems to be saturated and emitting CO2 back into the atmosphere. A huge amount of non-measurement calculation has been done, which may or may not reflect the totality or intricacy of what is really happening with our oceans, particularly vis a vis the ocean circulation and deep sequestration of atmospheric carbon.

The following article gives us a glimpse , from climate scientists , of just how complex this whole process is

'How much net CO2 do photosynthesizing plants and algae absorb per annum?'
The results are more than frustrating.....how many plants and and how much algae exist on our earth, how is this changing with time near 2008 or 2009, how has it been changing, what is the average uptake per plant , per kg of algae, we need remote sensing to answer these questions, and the satellite that might have answered this didn't make it all the way up into its proper intended orbit.....
