gsw_pot_rho_t_exact

potential density

Contents

USAGE:

pot_rho_t_exact = gsw_pot_rho_t_exact(SA,t,p,p_ref)

DESCRIPTION:

Calculates potential density of seawater.  Note that this 
function outputs potential density, not potential density 
anomaly; that is, 1000 kg/m^3 is not subtracted.

density.

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 )
p_ref = reference pressure                                     [ dbar ]
        ( i.e. reference absolute pressure - 10.1325 dbar )
SA & t need to have the same dimensions.
p & p_ref may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & t
are MxN

OUTPUT:

pot_rho_t_exact  =  potential density                        [ kg/m^3 ]
                    (not potential density anomaly)

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;]
p_ref  = 0
pot_rho_t_exact = gsw_pot_rho_t_exact(SA,t,p,p_ref)
