gsw_specvol_from_pot_enthalpy_ice_poly

Contents

USAGE:

specvol_ice = gsw_specvol_from_pot_enthalpy_ice_poly(pot_enthalpy_ice,p)

DESCRIPTION:

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

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

INPUT:

pot_enthalpy_ice  =  potential enthalpy of ice                 [ J/kg ]
p  =  sea pressure                                             [ dbar ]
       ( i.e. absolute pressure - 10.1325 dbar )

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

OUTPUT:

specvol_ice  =  specific volume of ice                        [ kg/m^3 ]

EXAMPLE:

pot_enthalpy_ice = ...
[-3.5654e5;-3.6195e5;-3.6085e5;-3.5902e5;-3.5629e5;-3.5159e5]
p = [     10;      50;     125;     250;     600;    1000;]

specvol_ice = gsw_specvol_from_pot_enthalpy_ice_poly(pot_enthalpy_ice,p)
