The micronutrient iron is now recognized to be important in regulating the magnitude and
dynamics of ocean primary productivity, making it an integral component of the ocean's …

Abstract The Southern Ocean, although relatively understudied owing to its harsh
environment and geographical isolation, has been shown to contribute substantially to …

Advances in iron biogeochemistry have transformed our understanding of the oceanic iron
cycle over the past three decades: multiple sources of iron to the ocean were discovered …

Numerical models of ocean biogeochemistry are relied upon to make projections about the
impact of climate change on marine resources and test hypotheses regarding the drivers of …

The availability of iron limits primary productivity and the associated uptake of carbon over
large areas of the ocean. Iron thus plays an important role in the carbon cycle, and changes …

Low levels of iron limit primary productivity across much of the Southern Ocean. At the basin
scale, most dissolved iron is supplied to surface waters from subsurface reservoirs, because …

The acidification caused by the dissolution of anthropogenic carbon dioxide (CO2) in the
ocean changes the chemistry and hence the bioavailability of iron (Fe), a limiting nutrient in …

Trace metals shape both the biogeochemical functioning and biological structure of oceanic
provinces. Trace metal biogeochemistry has primarily focused on modes of external supply …

Atmospheric aerosols have complex and variable compositions and properties. While
scientific interest is centered on the health and climatic effects of atmospheric aerosols …

Climate change is projected to significantly alter the delivery (stratification, boundary
currents, aridification of landmasses, glacial melt) of iron to the Southern Ocean. We report …
