sw.sigma.t {oce} | R Documentation |
Compute sigma-t, a quasi-potential density of seawater, minus 1000 kg/m^3.
sigma.t <- sw.sigma.t(S, t, p);
S |
in-situ salinity [PSU] |
t |
in-situ temperature [degC] |
p |
in-situ pressure [dbar] |
Definition: sigma_t=rho(S,t,0) - 1000 kg/m^3.
Quasi-potential density anomaly [kg/m^3].
