USAGE:
dynamic_enthalpy_CT_exact = gsw_dynamic_enthalpy_CT_exact(SA,CT,p)
DESCRIPTION:
Calculates the dynamic enthalpy of seawater from Absolute Salinity and
Conservative Temperature and pressure. Dynamic enthalpy is defined
as enthalpy minus potential enthalpy (Young, 2010).
Note that this function uses the full Gibbs function. There is an
alternative to calling this function, namely gsw_dynamic_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:
dynamic_enthalpy_CT_exact = dynamic 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;]
dynamic_enthalpy_CT_exact = gsw_dynamic_enthalpy_CT_exact(SA,CT,p)
