Below you can find a list of science highlights of main GEOTRACES discoveries on manganese research:

Science Highlights
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.

Science Highlights
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.

Science Highlights
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.

Science Highlights
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…

Science Highlights
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.

Science Highlights
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.
