Abstract:
We estimated E. huxleyi particulate inorganic to organic carbon ratio (PIC:POC) in order to detect changes in the carbonate counter-pump to carbon pump activity, which can act as either a positive or negative feedback to atmospheric CO2 modulating air-sea gas exchange.

Comment:
We calculated the molar ratio of particulate inorganic carbon to particulate organic carbon (PIC:POC) of the biomass obtained from SYRACO using formulas proposed by McClelland et al., 2016 (doi:10.1038/srep34263).
