GEOTRACES Science Highlights
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.
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...
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.
