## USAGE:

    Arsol = gsw_Arsol_SP_pt(SP,pt)

## DESCRIPTION:

    Calculates the argon, Ar, concentration expected at equilibrium with air
    at an Absolute Pressure of 101325 Pa (sea pressure of 0 dbar) including
    saturated water vapor.  This function uses the solubility coefficients
    as listed in Hamme and Emerson (2004).

    Note that this algorithm has not been approved by IOC and is not work
    from SCOR/IAPSO Working Group 127. It is included in the GSW
    Oceanographic Toolbox as it seems to be oceanographic best practice.

## INPUT:

    SP  =  Practical Salinity  (PSS-78)                         [ unitless ]
    pt  =  potential temperature                                   [ deg C ]
           with reference sea pressure (pr) = 0 dbar.

    SP & pt need to have the same dimensions.

## OUTPUT:

    Arsol = solubility of argon                                  [ umol/kg ]

## EXAMPLE:

    SP = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
    pt = [28.8099; 28.4392; 22.7862; 10.2262;  6.8272;  4.3236;]

    Arsol = gsw_Arsol_SP_pt(SP,pt)

    Arsol =
