Abstract:
We measured two years of total deposition at Kerguelen and Crozet Islands (South Indian Ocean) and three years of aerosol emission at Rio Galegos (Patagonia). We have shown a strong seasonal pattern of the Patagonian source with larger emissions during summer time. This seasonal pattern is recorded at Kerguelen. During winter, when Patagonian emission is low and storm are strong, dust is coming probably from Southern Africa and Patagonia, mixed. During other periods, Patagonia regularly feed Kerguelen, while Crozet is subjected to more variable sources.
