Select the couple of variables available. The flags which can be used are:
flag = 1 pH and CO2 given
flag = 2 CO2 and HCO3 given
flag = 3 CO2 and CO3 given
flag = 4 CO2 and ALK given
flag = 5 CO2 and DIC given
f
sys
0 if the manipulation is carried out in a system closed to the atmosphere or 1 if its is carried out in a system open to the atmosphere
var1
Value of the first variable in mol/kg, except for pH and for pCO2 in $\mu$atm
var2
Value of the second variable in mol/kg, except for pH
pCO2a
CO2 partial pressure in the atmosphere pCO2 in $\mu$atm. It is only used in systems open to the atmosphere (i.e. when sys=1)
vol
Volume of acid or base added in liter. By convention, it is given a negative sign for acid additions and a positive sign for base additions
N
Normality of the acid or base in mol/kg
S
Salinity
T
Temperature in degrees Celsius
P
Hydrostatic pressure in bar (surface = 0)
Pt
Concentration of total phosphate in mol/kg
Sit
Concentration of total silicate in mol/kg
Value
The function returns a data frame containing the following columns:
commentThe initial or final state water
SSalinity
TTemperature in degrees Celsius
PPressure in bar
pHpH
CO2CO2 concentration (mol/kg)
pCO2pCO2, CO2 partial pressure ($\mu$atm)
fCO2fCO2, CO2 fugacity ($\mu$atm)
HCO3HCO3 concentration (mol/kg)
CO3CO3 concentration (mol/kg)
DICDIC concentration (mol/kg)
ALKALK, total alkalinity (mol/kg)
