Abstract
Atmospheric concentrations and total deposition (wet+dry) of phosphorus were measured over the northwestern Mediterranean between april 1985 and march 1988. A seasonal cycle of both atmospheric concentrations and total deposition is observed, the higher values being recorded during the dry season. Air-mass trajectory analyses allow an identification of the major sources of atmospheric phosphorus: soil-derived dust from desert areas of north Africa and anthropogenic emissions from european countries. The impact of the atmospheric input as a source of phosphorus for surface Mediterrancan waters is tentatively assessed on both annual and seasonal time scales. The results suggest that the atmospheric input of phosphorus could be significant to Mediterranean oligotrophic zones, especially during summer when phosphorus input from deeper waters into the photic layer is minimum.
