pCO2insi {seacarb}

pCO2 at in situ temperature

Description

Correction to compensate for the difference in temperature between the temperature of measurement and in situ temperature.

Usage

pCO2insi(pCO2lab = 400, Tlab = 20, SST = 19)

Arguments

pCO2lab

Partial pressure of CO2 measured in the lab in \muatm

Tlab

Temperature of measurement in the lab in in degrees Celsius, default is 20oC

SST

Temperature in degrees Celsius, default is 19oC

Value

pCO2insi

Partial pressure of CO2 at in situ temperature in \muatm, the same units as that for the pCO2 input.

Note

The empirical correction applied is from Takahashi (1993) as recommended by Pierrot et al. (2009)
