## USAGE:

    deltaSA_atlas = gsw_deltaSA_atlas(p,long,lat)

## DESCRIPTION:

    Calculates the Absolute Salinity anomaly.

    Click for a more detailed description of the
    Absolute Salinity anomaly atlas value.

## INPUT:

    p     =  sea pressure                                           [ dbar ]
             ( i.e. absolute pressure - 10.1325 dbar )
    long  =  longitude in decimal degrees                     [ 0 ... +360 ]
                                                        or [ -180 ... +180 ]
    lat   =  latitude in decimal degrees north               [ -90 ... +90 ]

    p, long & lat need to have the same dimensions.

## OUTPUT:

    deltaSA_atlas  =  Absolute Salinity anomaly atlas value         [ g/kg ]

## EXAMPLE:

    p =    [   10;   50;  125;  250;  600; 1000;]
    lat =  [    4;    4;    4;    4;    4;    4;]
    long = [  188;  188;  188;  188;  188;  188;]

    [deltaSA_atlas, in_ocean] = gsw_deltaSA_atlas(p,long,lat)

    deltaSA_atlas =              in_ocean =
