Aeolian iron input to the ocean through precipitation

estimates suggest that the annual input of dissolved Fe by precipitation scavenging ranges from 0.5 to 4 1012 gyr 1, which is 4–30% of the total aeolian Fe fluxes. Dissolved Fe input through dry deposition is significantly lower than that by wet deposition, accounting for only 0.6–2.4 % of the total Fe
