Resupply of mesopelagic dissolved iron controlled by particulate iron composition

Bressac , M.; Guieu , C.; Ellwood, Michael; Tagliabue, Alessandro; Wagener, T.; Laurenceau-Cornec, E. C.; Whitby, H.; Sarthou, G.; Boyd, Phillip


The dissolved iron supply controls half of the oceans' primary productivity. Resupply by the remineralization of sinking particles, and subsequent vertical mixing, largely sustains this productivity. However, our understanding of the drivers of dissolved iron resupply, and their influence on its vertical distribution across the oceans, is still limited due to sparse observations. There is a lack of empirical evidence as to what controls the subsurface iron remineralization due to...[Show more]
