Seawater potential density anomaly

Description

Compute sigma-theta, the potential density of seawater, minus 1000 kg/m^3.

Usage

  sigma.theta <- sw.sigma.theta(S, t, p);

Arguments

S in-situ salinity [PSU]
t in-situ temperature [degC]
p in-situ pressure [dbar]

Details

Definition: sigma_theta=rho(S,theta(S,t,p),0) - 1000 kg/m^3.

Value

Potential density anomaly [kg/m^3].
