Float 3900225 (Fig. 12 bottom) presents a case where the
float was initially located over a well established front but
moved away from it after about 160 days, when its record
begins to mirror the smoothness of the climatological field.
While it was near the frontal region it found its parking position
sometimes on the high salinity side of the front, sometimes
on the low salinity side. If the mean of the two salinities
is taken it corresponds well to the climatological mean
