pHinsi: pH at in situ temperature

In seacarb: Calculates parameters of the seawater carbonate system

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)

Value

pH	pH at in situ temperature
