TL;DR: Chever et al. as discussed by the authors used a global ocean model to assess the impacts of an annual dissolved iron flux of approximately 9×108 mol, as estimated from regional observations of hydrothermal activity.

TL;DR: In this article, an important role of sea ice in the global biogeochemical cycles, promoted by active biological and chemical processes within the sea ice, fluid and gas exchanges at the sea-ice interface through an often permeable sea ice cover, and tight physical, biological, and chemical interactions between the Sea ice, the ocean and the atmosphere.

TL;DR: In this article, a high-resolution study of the water column of the Southern Ocean was conducted using 27 stations from 65.50 to 44.00 m with up to 15 depths (0-4440 m) between Antarctica and Tasmania along the 140!E meridian.

TL;DR: In this paper, the relative importance of sea ice in supplying Fe to East Antarctic surface ocean waters was evaluated compared to other possible sources, and the most striking feature was that total-dissolvable Fe concentrations in sea ice were up to an order of magnitude higher than those measured in the underlying seawater.

TL;DR: The eGEOTRACES Electronic Atlas is the visual representation of the IDP2014 data providing section plots and a new kind of animated 3D scenes that provide geographical and bathymetric context that is crucial for the interpretation and assessment of observed tracer plumes.
