gsw_sigma2: Potential density anomaly referenced to 2000 dbar

Description

This uses the 48-term density equation, and returns potential density referenced to a pressure of 2000 dbar, minus 1000 kg/m^3.

Usage

gsw_sigma2(SA, CT)

Arguments

SA

Absolute Salinity [ g/kg ]

CT

Conservative Temperature [ deg C ]

Value

potential density anomaly [ kg/m^3 ]
