pH at in situ temperature

Description

pH at in situ temperature

Usage

pHinsi(PH=8.2, ALK=2.4e-3, Tinsi=20, Tlab=25, S=35, Pt=0, Sit=0, k1k2 = "l", kf = "pf", pHscale = "T")

Arguments

PH pH measured in the laboratory
ALK ALK, total alkalinity (mol/kg)
Tinsi In situ temperature in degrees Celsius
Tlab Measurement temperature in degrees Celsius
S Salinity
Pt value of the concentration of total phosphate in mol/kg
Sit the value of the total silicate in mol/kg
k1k2 "l" for using K1 and K2 from Lueker et al. and "r" for using K1 and K2 from Roy et al. , default is "l"
kf "pf" for using Kf from Perez and Fraga (1987) and "dg" for using Kf from Dickson and Goyet (1979), default is "pf"
pHscale choice of pH scale: "T" for the total scale, "F" for the free scale and "SWS" for using the seawater scale, default is "T" (total scale)
