Description

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

Usage

1
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
