sw.T.freeze {oce} | R Documentation |
Compute freezing temperature of seawater.
T.freeze <- sw.T.freeze(ctd) T.freeze <- sw.T.freeze(S, p=NULL)
ctd |
an object of class "ctd ". |
S |
salinity [PSU] |
p |
pressure [dbar] |
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.
Temperature [degC]
