## USAGE:

    SP_baltic = gsw_SP_from_SA_Baltic(SA,long,lat)

## DESCRIPTION:

    Calculates Practical Salinity for the Baltic Sea, from a value computed
    analytically from Absolute Salinity.
    Note. This program will only produce Practical Salinty values for the
    Baltic Sea.

## INPUT:

    SA    =  Absolute Salinity in the Baltic Sea                    [ g/kg ]
    long  =  Longitude in decimal degress east                [ 0 ... +360 ]
    lat   =  Latitude in decimal degress north               [ -90 ... +90 ]

## OUTPUT:

    SP_baltic  =  Practical Salinity                            [ unitless ]

## EXAMPLE:

    SA    = [6.6699; 6.7738; 6.9130; 7.3661; 7.5862; 10.3895;]
    long  = [    20;     20;     20;     20;     20;      20;]
    lat   = [    59;     59;     59;     59;     59;      59;]

    SP_baltic = gsw_SP_from_SA_Baltic(SA,long,lat)

    SP_baltic =

       6.568254668732918
       6.671923516821352
       6.810813831103450
