kconv: Conversion factors to change the pH scale of dissociation...

In seacarb: Calculates parameters of the seawater carbonate system

Description

Conversion factors from the total scale to the free and seawater scales

Usage

kconv(S=35,T=25, P=0)

Arguments

S	Salinity, default is 35
T	Temperature in degrees Celsius, default is 25oC
P	Hydrostatic pressure in bar (surface = 0), default is 0

Value

The function returns a list with 3 conversion factors :

ktotal2SWS	to convert from the total scale to seawater scale
ktotal2free	to convert from the total scale to the free scale
kfree2SWS	to convert from the free scale to the seawater scale

Examples

##To convert dissociation constants from the total scale to the free scale
## (at salinity=35, temperature=25oC and atmospheric pressure):
kconv(35,25,0)
conv <- kconv()
 c(K1_total=K1(),K1_SWS=K1()*conv$ktotal2SWS,K1_free=K1()*conv$ktotal2free)
