swSTrho: Seawater salinity from temperature and density
Description
Compute in-situ salinity, given temperature,
density, and pressure.
Usage
swSTrho(temperature, density, pressure)
Arguments
temperature
in-situ temperature [$^\circ$C]
density
in-situ density or sigma value [$kg/m^3$]
pressure
in-situ pressure [dbar]
Value
In-situ salinity [PSU].
Details
Finds the salinity that yields the given density, with the
given temperature and pressure. The method is a bisection search with
a salinity tolerance of 0.001. The isopycnal lines on
temperature-salinity diagrams (plot.TS) are computed
with this function.
