Here we demonstrate enhanced natural community APase activity following iron amendment within the low zinc and moderately low iron Western North Atlantic. In contrast we find no evidence for trace metal limitation of APase activity beneath the Saharan dust plume in the Eastern Atlantic. Such intermittent iron limitation of microbial phosphorus acquisition provides an additional facet in the argument for iron controlling the coupling between oceanic nitrogen and phosphorus cycles. ... : Supplement to: Browning, Thomas J; Achterberg, Eric Pieter; Yong, Jaw-Chuen; Rapp, Insa; Utermann, Caroline; Engel, Anja; Moore, C M (2017): Iron limitation of microbial phosphorus acquisition in the tropical North Atlantic.
