ppH {seacarb} | R Documentation |
Calculates the carbonate chemistry after pH manipulations through addition of acid or base
ppH(flag, sys, var1, var2, pCO2a, vol, N, S=35, T=20, P=0, Pt=0, Sit=0)
flag |
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 flag = 6 pH and HCO3 given flag = 7 pH and CO3 given flag = 8 pH and ALK given flag = 9 pH and DIC given flag = 10 HCO3 and CO3 given flag = 11 HCO3 and ALK given flag = 12 HCO3 and DIC given flag = 13 CO3 and ALK given flag = 14 CO3 and DIC given flag = 15 ALK and DIC given flag = 21 pCO2 and pH given flag = 22 pCO2 and HCO3 given flag = 23 pCO2 and CO3 given flag = 24 pCO2 and ALK given flag = 25 pCO2 and DIC given |
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 μatm |
var2 |
Value of the second variable in mol/kg, except for pH |
pCO2a |
CO2 partial pressure in the atmosphere pCO2 in μatm. 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 |
The function returns a data frame containing the following columns:
comment |
The initial or final state water |
S |
Salinity |
T |
Temperature in degrees Celsius |
P |
Pressure in bar |
pH |
pH |
CO2 |
CO2 concentration (mol/kg) |
pCO2 |
pCO2, CO2 partial pressure (μatm) |
fCO2 |
fCO2, CO2 fugacity (μatm) |
HCO3 |
HCO3 concentration (mol/kg) |
CO3 |
CO3 concentration (mol/kg) |
DIC |
DIC concentration (mol/kg) |
ALK |
ALK, total alkalinity (mol/kg) |
OmegaAragonite |
Omega aragonite, aragonite saturation state |
OmegaCalcite |
Omega calcite, calcite saturation state |
