Description: 

Silicate concentration estimated as the average of the values from the first and last timepoint. Biologically there should be no change in silicate concentration because coccolithophores do not take up silicate. However silicate values are needed to calculate the carbonate chemistry parameters in CO2sys so the average was used for timepoints when carbonate chemistry values were calculated.
