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 (plotTS) are computed with this function.
