  This article presents a monitoring of the atmospheric dust in the south polar
region during spring of martian year 27. Our goal is to contribute to
identifying the regions where the dust concentration in the atmosphere shows
specific temporal patterns, for instance high, variable, and on the rise due to
lifting or transport mechanisms. This identification is performed in relation
with the seasonal ice regression. Based on a phenomenological examination of
the previous results, hypothesis regarding the origin of aerosol activity of
the southern polar region are proposed. This is of paramount importance since
local dust storms generated in this region sometimes grow to global
proportions. T
