gsw_Helmholtz_energy_t_exact

Helmholtz energy of seawater

Contents

USAGE:

Helmholtz_energy_t_exact = gsw_Helmholtz_energy_t_exact(SA,t,p)

DESCRIPTION:

Calculates the Helmholtz energy of seawater
TEOS-10

energy.

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:

Helmholtz_energy_t_exact = Helmholtz energy                     [ J/kg ]

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;]
Helmholtz_energy_t_exact = gsw_Helmholtz_energy_t_exact(SA,t,p)
