Whatever the particular circumstances of individual float may be, it is fair to assume that any change of water properties
observed at the depth of AAIW is due to the fact that the float encountered different parcels of AAIW after every ascent
and dive cycle.
This allows us to study the spatial structure of AAIW in some detail. AAIW is particularly suited to such a study because it is associated with a distinct salinity minimum.
If the ocean is dominated by smooth diffusive flow, any change in the salinity minimum observed by the floats should be slow and uniform, from lower salinity values closer to the AAIW formation region to higher values further afield. If, on the other hand, the flow is turbulent and AAIW is interspersed with fronts and eddies, variations of the AAIW salinity minimum will show more random behaviour.
