The interplay between regeneration and scavenging fluxes drives ocean iron cycling

Tagliabue, Alessandro; Bowie, Andrew; DeVries, Timothy; Ellwood, Michael; Landing, William M.; Milne, Angela; Ohnemus, Daniel C.; Twining, B.S.; Boyd, Phillip


Despite recent advances in observational data coverage, quantitative constraints on how different physical and biogeochemical processes shape dissolved iron distributions remain elusive, lowering confidence in future projections for iron-limited regions. Here we show that dissolved iron is cycled rapidly in Pacific mode and intermediate water and accumulates at a rate controlled by the strongly opposing fluxes of regeneration and scavenging. Combining new data sets within a watermass...[Show more]
