  Atmosphere is recognized to be an important pathway for the transport of trace elements of continental origin to oceanic areas.The input of Nitrogen (N),Phosphorus (P),and Iron (Fe),which are essential nutrients for the biological growth of oceanic biota,is of particular interest,especially for oligotrophic oceanic areas and semienclosed seas,such as the Mediterranean.Iron is present in environmental samples (rain,dry deposition samples,aerosols) as particulate and dissolved Fe and includes both Fe(II) and Fe(III) species.Model calculations and correlation analysis indicate that in the aqueous phase Fe(II)(aq) occurs almost exclusively as the free Fe whereas Fe(III)(aq) occurs as both iron oxalate and Fe(OH)2 +(aq) depending on the pH range.
