Abstract

Iron is important in determining the biogeochemistry of the oceans and has a strong control on ocean productivity. The sources of iron vary from atmospheric supply of desert dust, resuspension of oceanic sediments and fluxing of volcanic material out of vents into the deep ocean. Iron is very reactive in the water column and interacts with organic ligands, to form metal complexes, and particles via surface association. The interaction of these processes determines the ocean basin-wide distribution of total dissolved iron. Observational measurements of 234Th and 238U were used to estimate the particle scavenging fluxes of iron in the subpolar North Atlantic, resulting in mean iron losses of 1.03�0.89 pM Fe d
