Warning on Polonium-210/Lead-210 data quality!
Alerted by the fact that the published Polonium-210:Lead-210 profiles showed ubiquitous disequilibrium in the deep ocean, Mark Baskaran and colleague conducted a critical review…

Xu and Weber developed a data-assimilation model of the aluminum oceanic cycle.
Using historical (1987-2007) and recent GEOTRACES data, authors compiled an impressive data set comprising dissolved, filtered and trap-collected particulate iron
They both assess the potential of a number of bioactive elements and their isotopes to inform on past ocean productivity.
Joint Science Highlight with US Ocean Carbon and Biogeochemistry (OCB). Iron (Fe) is a key element to life but in seawater it is present at extremely low concentrations. The scarcity […]
After a brief reminder on the motivation and foundation processes of the international and ambitious programme GEOTRACES, Bob Anderson (2020, see reference below) proposes an overview of many results of […]
Joint Science Highlight with US-Ocean Carbon & Biogeochemistry (OCB). Carbon storage in the ocean is sensitive to the depths at which particulate organic carbon (POC) is respired back to CO2 […]
Microorganisms play a central role in the transfer of matter and energy in the marine food web. Microbes depend on micronutrients (e.g. iron, cobalt, zinc, and a host of other […]
Browning and co-workers (2017, see reference below) find that multiple nutrients must be supplied to stimulate phytoplankton growth on the southeast Atlantic GEOTRACES GA08 cruise. The paper has been published […]
