Description

Compute freezing temperature of seawater.

Usage

swTFreeze(salinity, pressure=NULL)

Arguments

salinity

either salinity [PSU] or a ctd object from which salinity will be inferred.

pressure

seawater pressure [dbar]

Value

• Temperature [$^\circ$C]

Details

In the first form, the argument is a ctd object, from which the salinity and pressure values are extracted and used to for the calculation.
