How will the key science questions be addressed?

The global carbon cycle

What is the effect of climate variability on the uptake of anthropogenic CO2 by the ocean?

How does the accumulation of carbon in the ocean, and its release from the ocean, respond to climate variability?

How will the biotic changes impact on carbon uptake and sequestration?

What factors determine the efficiency of the biological carbon pump?

These questions will be partly addressed through the local observations of pCO2 at the Maria island National Reference Station and other observations.

What is the effect of climate variability on the ocean's biological pump?
