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 Riley (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) |
