gsw_pot_enthalpy_from_pt_ice_poly
potential enthalpy from potential temperature of ice (polynomial)
Contents
USAGE:
pot_enthalpy = gsw_pot_enthalpy_from_pt_ice_poly(pt0_ice)
DESCRIPTION:
Calculates the potential enthalpy of seawater from potential temperature (whose reference sea pressure is zero dbar). This is is a computationally efficient polynomial fit to the potential enthalpy of ice.
INPUT:
pt0_ice = potential temperature of ice (ITS-90) [ deg C ]
OUTPUT:
pot_enthalpy_ice = potential enthalpy of ice [ J/kg ]
EXAMPLE:
pt0_ice = [-10.7856; -13.4329; -12.8103; -12.2600; -10.8863; -8.4036;]
pot_enthalpy_ice = gsw_pot_enthalpy_from_pt_ice_poly(pt0_ice)
pot_enthalpy_ice =
