Abstract

Atmospheric dust has been sampled over the Mediterranean by mesh panels and by filtration during a three years research program. The concentration and the composition of the dust was investigated and have been shown to depend on the origin and mode of transport.

Occasional episodes of direct transport contrast with more continuous nature of “background” indirect transport. Mass concentration values emphasize the indirect eolian supply. Along constant sampling tracks, dust mineralogy shows a clear evolution of typical “mineral assemblages” depending on the source areas of the particulate and on meteorological patterns variable on synoptic scale. The average composition of the dust samples has been compared with that of marine sediments, and it is suggested that wind-blown dust contributes significantly to marine sedimentation in particular areas of the Mediterranean.
