gsw_rho_t_exact

in-situ density of seawater

Contents

USAGE:

rho_t_exact = gsw_rho_t_exact(SA,t,p)

DESCRIPTION:

Calculates in-situ density of seawater from Absolute Salinity and
in-situ temperature.  Note that the output, rho_t_exact, is density,
not density anomaly; that is, 1000 kg/m^3 is not subracted from it.

INPUT:

SA  =  Absolute Salinity                                        [ g/kg ]
t   =  in-situ temperature (ITS-90)                            [ deg C ]
p   =  sea pressure                                             [ dbar ]
        ( i.e. absolute pressure - 10.1325 dbar )
SA & t need to have the same dimensions.
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & t are MxN.

OUTPUT:

rho_t_exact  =  in-situ density (not density anomaly)         [ kg/m^3 ]

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
t =  [28.7856; 28.4329; 22.8103; 10.2600;  6.8863;  4.4036;]
p =  [     10;      50;     125;     250;     600;    1000;]
rho_t_exact = gsw_rho_t_exact(SA,t,p)
