Long distance dissolved iron transport in the North-East Pacific revealed by multiple tracers and an ocean circulation model
Sieber and co-authors have made extensive use of the multi-tracer approach, coupled to an oceanic circulation model…
Manganese
What are the drivers of the distributions of cadmium, nickel, zinc, copper and cobalt, manganese and aluminium in the Atlantic Ocean? Two papers are tackling this issue
Chen and co-authors reveal that the distributions of dissolved tracers at depth in the South Atlantic are predominantly controlled by the mixing of North Atlantic Deep Water and waters of Antarctic origin…
Aluminium, manganese, iron, cobalt, and lead display contrasting fate along north–south and east–west sections in the North Pacific Ocean
Chan et co-authors provide a comprehensive view of trace metal distribution in the subarctic Pacific Ocean.
Extremely high radioactive levels in the manganese nodules
Volz and co-authors demonstrate that radioisotopes in the manganese nodules mostly exceed exempt activity levels…
A detailed study of the land-ocean input of dissolved iron, manganese and cobalt in the Northeast Atlantic Ocean
Chen and co-authors propose a detailed study of the spatial and seasonal distributions of dissolved iron, manganese and cobalt in the Northeast Atlantic continental margin.
Dissolved manganese distribution in the Arabian Sea reveals many variable triggers
Analysis of dissolved manganese on samples collected on GEOTRACES cruises allowed Singh and colleagues to establish its basin-wide distribution in the Arabian Sea.
Different fates of four poorly soluble trace elements in the Pacific Ocean
Zheng and co-authors present the full-depth distributions of aluminum, lead, manganese and copper in the western South Pacific.
Shelf sediments in the Benguela Upwelling System as a major source of trace metals to the shelf and eastern South Atlantic Ocean
Liu and her colleagues investigated dissolved trace metals distributions within the Benguela Upwelling System sampled from GEOTRACES GA08 cruise.
Distributions, boundary inputs, and scavenging processes of trace metals in the East Sea (Japan Sea)
Seo and his colleagues show pronounced atmospheric and shelf inputs of trace elements in the Japan Sea.
New trace metal data in the Seas of Japan and Okhotsk
Nakaguchi and colleagues realized full-depth and section distributions of traces metals collected from the Seas of Japan and Okhotsk.
Contrasting distributions of dissolved manganese, nickel, cadmium and zinc in the Mediterranean Sea
Extensive trace metal clean sampling during the Dutch GEOTRACES cruise in the Mediterranean Sea allowed Middag and his colleagues to establish the basin scale distribution of these trace metals.
Surprising conservativity of trace metals along a costal embayment salinity gradient
Chen and co-workers analyzed an array of trace metals together with Rare Earth Elements in a salinity gradient in the Jinhae Bay, the largest semi-enclosed bay in South Korea…
Manganese: a surprising co-limiting factor of phytoplankton growth in the Southern Ocean
One of the main consequences of this work is that manganese should be included in ocean-climate models, more particularly to improve the accuracy of their predictions in this area.
Spatial and temporal variability of bioactive trace metals, speciation and organic metal-binding ligands in the eastern Gulf of Mexico
Mellett and Buck present the concentrations of bioactive trace metals (Fe, Cu, Mn, Zn, Co, Ni, Cd, and Pb), Fe-and Cu-binding organic ligands, and electroactive Fe-binding humic substances in the eastern Gulf of Mexico.
Dissolved iron and manganese fates reveal processes along the hydrothermal TAG plume
Authors performed high-spatial resolution analyses of dissolved iron and manganese samples collected at the Mid Atlantic Ridge
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?
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 […]
