gsw_deltaSA_from_SP

`Absolute Salinity Anomaly from Practical Salinity`

USAGE:

`delta_SA = gsw_deltaSA_from_SP(SP,p,long,lat)`

DESCRIPTION:

`Calculates the Absolute Salinity Anomaly from Practical Salinity.`
 ```Click for a more detailed description of the Absolute Salinity Anomaly.```

INPUT:

```SP   =  Practical Salinity  (PSS-78)                        [ unitless ]
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 ]```
`SP, p, long & lat need to have the same dimensions.`

OUTPUT:

`deltaSA  =  Absolute Salinity Anomaly                          [ g/kg ]`

EXAMPLE:

```SP =   [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
p =    [     10;      50;     125;     250;     600;    1000;]
lat =  [      4;       4;       4;       4;       4;       4;]
long = [    188;     188;     188;     188;     188;     188;]```
`deltaSA = gsw_deltaSA_from_SP(SP,p,long,lat)`
`deltaSA =              in_ocean =`
