The Live Access Server able you to look at an area along slightly different points of view. Low resolution gives the overview; variance shows the more turbulent areas (where the variations are strongest), etc. You can also plot averages over the whole available period (just over two years just now). This last map is more difficult to decipher, since very strong eddies can imprint their hight in it -- this is one of the reasons why we need long time series of altimetry data, to lessen this effect with more measurements. Last (but not least), if some eddies strike you as especially interesting, you can zoom on them (on a 10°x10° maximum area), to visualize the geostrophic currents that derive from their slopes.
