sw.S.C.T.p: Seawater salinity from conductivity ratio, temperature and pressure

Description

Compute salinity, given conductivity ratio, temperature, and pressure.

Usage

S <- sw.S.C.T.p(C, t, p);

Arguments

C

conductivity ratio [unitless]

t

in-situ temperature [$^\circ$C]

p

pressure [dbar]

Value

• Salinity [PSU].

Details

Calculate S from what is actually measured by the CTD, i.e. the conductivity ratio C, the in-situ temperature T, and the pressure p. Often this is done by the CTD processing software, but sometimes it is helpful to do this directly, e.g. when there is a concern about mismatches in sensor response times. S is calculated using the UNESCO algorithm described by Fofonoff and Millard (1983).
