This section presents the GEOTRACES scientific activities.
Intense benthic nepheloid layers in the Northwest Atlantic Ocean lead to unexpected distributions of dissolved and particulate thorium-230 and protactinium-231
Chen and colleagues explore the behaviour of thorium-230 and protactinium-231 in the benthic nepheloid layers…
Specific features characterize the dissolved iron distribution in the North Western Indian Ocean
Venkatesh Chinni and Sunil Kumar Singh propose dissolved iron profiles along two meridional transects realized during spring and fall seasons between the Arabian Sea and the sub-tropical western Indian Ocean…
Quantifying the weathered fluxes to the ocean is far from over: the overlooked role of rock coast erosion
This study reveals that cliff derived sediment supply is only three times less than the solid discharge of rivers for Europe.
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.
Anthropogenic aerosol has become a dominant source of zinc in the deep water of the Northern South China Sea
Liao and colleagues determined zinc concentrations and isotope compositions in sinking particles collected in the Northern South China Sea…
An updated global ocean chromium biogeochemical cycle
Janssen and co-authors present an exhaustive compilation of ocean chromium data…
Mercury stable isotopes constrain atmospheric pathways to the ocean
The study’s results hold promise that the implementation of anti-pollution measures under the Minamata Convention will likely result in a faster decrease of oceanic mercury levels than previously thought.
New impetus to the debate on the sources of dissolved aluminium to the ocean
This study challenges the paradigm that dissolved aluminium in the bottom waters of the Arctic basins could result from a top-down process.
Icebergs as sources of trace metals to the ocean: which impact?
Earth’s Ice Sheets are known to release significant quantities of lithogenic particles into the ocean every year, but how does this material affect trace metal availability in the ocean?
