f2pCO2 {seacarb}

Converts the CO2 fugacity to CO2 partial pressure

Description

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

Usage

f2pCO2(T = 25, Patm=1, P=0, fCO2)

Arguments

T

Temperature in degrees Celsius, default is 25oC

Patm

Surface atmospheric pressure in atm, default 1 atm

P

Hydrostatic pressure in bar, default is 0 bar (surface)

fCO2

Fugacity of CO2 in \muatm, the same units as that for the pCO2 output

Value

pCO2

Partial pressure of CO2 in \muatm, the same units as that for the fCO2 input

Note

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