The biogeochemical ventures of dissolved iron and manganese across the Arctic Ocean
The spatial distributions and biogeochemical cycling of dissolved Fe (dFe) and dissolved manganese (dMn) across the Arctic Ocean were established during summer and fall 2015. The Canadian GEOTRACES transect extended […]

About the decoupled fates of aluminium, manganese, cobalt and lead in the North Pacific Ocean
Did you know that each of these tracers could follow its own marine story, quite decoupled from the others? This is what is shown and discussed by Zheng and co-workers […]

Manganese in the west Atlantic Ocean in the context of the first global ocean circulation model of manganese
Marco van Hulten and co-workers (2017, see reference below) ran a global ocean model to understand manganese (Mn), a biologically essential element. The model shows that: (i) in the deep […]

What controls hydrothermal plume transport of iron over 4000 km in the deep Pacific Ocean?
The striking extension of the dissolved iron and manganese plumes over more than 4000 km from their hydrothermal sources along the US GEOTRACES East Pacific Zonal Transect (EPZT) cruise (GP16) has […]

Unprecedented set of dissolved manganese data in the North Atlantic Ocean (US GEOTRACES cruise)
Manganese (Mn) is an essential nutrient for biological growth. In the ocean, manganese distribution is sensitive to several processes: redox conditions, photochemistry, biological activity, abiotic scavenging, and also eolian, hydrothermal […]

Overview of the dissolved iron, manganese and aluminium distributions along the North Atlantic GEOTRACES GA03 section
Three trace elements distributions (iron, manganese and aluminium) help to constrain the sources of chemical elements in the North Atlantic Ocean. Atmospheric, Mediterranean Sea and margin inputs are confirmed while […]

Large amounts of soluble manganese(III) identified at the land-ocean interface
Soluble manganese(III) [Mn(III)] is a phase traditionally considered non important in aqueous redox reactions. However, applying a spectrophotometric method sensitive to Mn oxidation state, Madison and co-authors found that up […]

Basin-scale inputs of cobalt, iron, and manganese from the Benguela-Angola front to the South Atlantic Ocean
The African coast appeared to be a major source of dissolved total dissolved cobalt, iron, manganese, and labile cobalt to the South Atlantic basin, with high cobalt concentrations in the […]
