Description/Abstract
Since the mid-1980s, our understanding of nutrient limitation of oceanic primary production has
radically changed. Mesoscale iron addition experiments (FeAXs) have unequivocally shown that
iron supply limits production in one-third of the world ocean, where surface macronutrient
concentrations are perennially high. The findings of these 12 FeAXs also reveal that iron supply
exerts controls on the dynamics of plankton blooms, which in turn affect the biogeochemical
cycles of carbon, nitrogen, silicon, and sulfur and ultimately influence the Earth climate system.
However, extrapolation of the key results of FeAXs to regional and seasonal scales in some
cases is limited because of differing modes of iron supply in FeAXs and in the modern and
paleo-oceans. New research directions include quantification of the coupling of oceanic iron and
carbon biogeochemistry.
