pHconv {seacarb} | R Documentation |
Conversion factors from the total scale to the free and seawater scales
pHconv(S=35,T=25, P=0)
S |
Salinity, default is 35 |
T |
Temperature in degrees Celsius, default is 25oC |
P |
Hydrostatic pressure in bar (surface = 0), default is 0 |
The function returns a list with 3 conversion factors :
pHtotal2SWS |
to convert from the total scale to seawater scale |
pHtotal2free |
to convert from the total scale to the free scale |
pHfree2SWS |
to convert from the free scale to the seawater scale |
