In seacarb: Seawater Carbonate Chemistry

Converts pCO2 (partial pressure in CO2) into fCO2 (fugacity of CO2)

Description

Converts pCO2 (partial pressure in CO2) into fCO2 (fugacity of CO2)

Usage

p2fCO2(T = 25, Patm=1, P=0, pCO2)

Arguments

T	Temperature in degrees Celsius, default is 25oC
Patm	Surface atmospheric pressure in atm, default is 1 atm
P	Hydrostatic pressure in bar, default is 0 bar (surface)
pCO2	Partial pressure in CO2 in \muatm, the same units as that for the fugacity output

Value

fCO2	Fugacity of CO2 in \muatm, the same units as that for the pCO2 input.

Note

Warning: pCO2 estimates below 100 m are subject to considerable uncertainty. See Weiss (1974) and Orr et al. (2015)
