gsw_pot_enthalpy_from_specvol_ice_poly

Contents

USAGE:

specvol_ice = gsw_specvol_ice(t,p)

DESCRIPTION:

Calculates the potential enthalpy of ice from the specific volume  
of ice.  The reference sea pressure of the potential enthalpy is zero
dbar. 

Note that this is a computationally efficient polynomial version of 
specfic volume from potential enthalpy ice.

INPUT:

specvol_ice  =  specific volume of ice                       [ kg/m^3 ]
p  =  sea pressure                                             [ dbar ]
       ( i.e. absolute pressure - 10.1325 dbar )

p may have dimensions 1x1 or Mx1 or 1xN or MxN, where specvol_ice is MxN.

OUTPUT:

pot_enthalpy_ice  =  potential enthalpy of ice                  [ J/kg ]

EXAMPLE:

specvol_ice = ...
       [1.0889e-3; 1.0884e-3; 1.0884e-3; 1.0884e-3; 1.0882e-3; 1.0881e-3]
p = [     10;      50;     125;     250;     600;    1000;]

pot_enthalpy_ice = gsw_pot_enthalpy_from_specvol_ice_poly(specvol_ice,p)

pot_enthalpy_ice =
