pHDrift: Compute the pH drift in seawater after partial equilibration...

In EcoNum/EN-test: Test Code for EcoNum

Description

Calculate the final pH of seawater after a given time considering equilibration with a mixed gas phase considered as infinitely large (constant pCO2air).

Usage

pHDrift(pHini, alk, elapsed, pCO2air = 400, tau = 560)

Arguments

pHini	The initial pH in the seawater.
alk	The initial alkalinity in mmol/kg.
elapsed	Time elapsed waiting for equilibration in min.
pCO2air	CO2 partial pressure of the gas phase in microatm
tau	Cinetic constant for gas-liquid exchange of CO2 in the system.

Value

the final pH

Examples

pHDrift(pHini = 7.5, alk = 0.00230, elapsed = 60)
pHDrift(pHini = c(7, 8), alk = 0.00230, elapsed = c(60, 12000))
plot(1:500, pHDrift(pHini = 7, alk = 0.00230, elapsed = 1:500))
