GEOTRACES Science Highlights
Microbial trace metal trafficking on marine particles
This study provides evidence for the processing of nine particulate trace metals in multiple manners by diverse microbial communities.
Volcanic emissions in the Southern Ocean: an efficient and unexpected source of iron for this remote area
This study suggests that volcanic emission can represent a significant source of bioavailable iron to open ocean anaemic ecosystems.
Surprisingly heavy silicon isotopes in the surface and deep Arctic Ocean
Brzezinski and his colleagues report on a comprehensive study of the Arctic Ocean silicic acid concentrations and silicon isotopic composition...
Unique winter dataset of particulate and dissolved cadmium in the Indian sector of the Southern Ocean
Cloete and collaborators analysed particulate and dissolved cadmium at 7 stations in austral winter along a North South section off South Africa.
