International audience We have monitored the atmospheric concentrations of Be-7 and P-32 at the French Antarctic station "Dumont d'llrville" from 1977 to 1981. The results show that the mean monthly value of the air flux exchanged between stratosphere and troposphere is particularly high close to Antarctica. reaching up to 60 kg m-* day I .
