- Download mean dynamic topography (m2.s-1) from Argo and ship data . Please feedback to me and reference if you use it.
- Download matrix of ACC front (PF, SAF and SAF-North) position from 1993 to now (~100 Mo). Please feedback to me and reference if you use it.

1) Subantarctic Front variability. panel (a): Map of bottom topography in the Southern Ocean with the mean SAF position superimposed (solid line black), the dashed line represents the two standard deviation enveloppe around th mean SAF position. Panel (b): The frequency of occurrence of SSH gradients at the SAF position, as measure of the front intensity at each longitude. Colors range from black (often) to white (rare). Also marked are the mean SSH gradient at each longitude (solid black) and the two standard deviation limit (dashed line). Panel (c): Depth of the bathymetry along the mean SAF pathway.
2) Polar Front variability. Same as above for the PF
