SW_Enthalpy    Specific enthalpy of seawater

=========================================================================
USAGE:  h = SW_Enthalpy(T,S)

DESCRIPTION:
   Specific enthalpy of seawater at atmospheric pressure (0.1 MPa) using Eq. (43)
   given by [1] which best fit the data of [2]. The pure water specific
   enthalpy equation is a best fit to the data of [3]. 
   Values at temperature higher than the normal boiling temperature are
   calculated at the saturation pressure.

INPUT:  (all must have same dimensions)
   T = temperature [degree C] (ITS-90)
   S = salinity    [g/kg] (reference-composition salinity)

OUTPUT:
   h = specific enthalpy   [J/kg]

VALIDITY: 10 < T < 120 C, 0 < S < 120 g/kg
 
ACCURACY: 1.5
