A key Earth system science question is the role of atmospheric deposition in supplying vital
nutrients to the phytoplankton that form the base of marine food webs. Industrial and …

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

The Southern Ocean plays a critical role in regulating global climate as a major sink for
atmospheric carbon dioxide (CO2), and in global ocean biogeochemistry by supplying …

Iron is important in regulating the ocean carbon cycle. Although several dissolved and
particulate species participate in oceanic iron cycling, current understanding emphasizes …

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 …

Atmospheric deposition is a source of potentially bioavailable iron (Fe) and thus can partially
control biological productivity in large parts of the ocean. However, the explanation of …

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 …

Aerosols supply bioaccessible iron to marine biota which could affect climate through
biogeochemical feedbacks. This paper review progresses in research on pyrogenic aerosol …

The manuscript assesses the current and expected future global drivers of Southern Ocean
(SO) ecosystems. Atmospheric ozone depletion over the Antarctic since the 1970s, has been …
