gsw_enthalpy_CT_exact

Contents

USAGE:

enthalpy_CT_exact  =  gsw_enthalpy_CT_exact(SA,CT,p)

DESCRIPTION:

Calculates specific enthalpy of seawater. 

Note that this function uses the full Gibbs function.  There is an 
alternative to calling this function, namely gsw_enthalpy(SA,CT,p), which
uses the computationally efficient 75-term expression for specific volume
in terms of SA, CT and p (Roquet et al., 2015).

INPUT:

SA  =  Absolute Salinity                                        [ g/kg ]
CT  =  Conservative Temperature                                [ deg C ]
p   =  sea pressure                                             [ dbar ]
       ( i.e. absolute pressure - 10.1325 dbar )

SA & CT need to have the same dimensions.
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & CT are MxN.

OUTPUT:

enthalpy_CT_exact  =  specific enthalpy                         [ J/kg ]

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
CT = [28.8099; 28.4392; 22.7862; 10.2262;  6.8272;  4.3236;]
p =  [     10;      50;     125;     250;     600;    1000;]

enthalpy_CT_exact = gsw_enthalpy_CT_exact(SA,CT,p)
