pgas: pgas

Description

Calculates the carbonate chemistry after changes in pCO2 generated by gas bubbling

Usage

pgas(flag, var1, var2, pCO2g, S=35, T=20, P=0, Pt=0, Sit=0)

Arguments

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 f
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
pCO2g
CO2 partial pressure of the gas used for bubbling in $\mu$atm
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)
  • OmegaAragoniteOmega aragonite, aragonite saturation state
  • OmegaCalciteOmega calcite, calcite saturation state
