GEOTRACES Science Highlights
Dissolved iron and manganese fates reveal processes along the hydrothermal TAG plume
González-Santana and co-workers performed high-spatial resolution analyses of dissolved iron and manganese samples collected at the Mid Atlantic Ridge

The power of combining geochemical tracer data with direct current measurements
Learn about new discoveries done combining seawater Rare Earth Elements concentrations and direct physical oceanographic observations

Loss of old Arctic sea ice increases methylmercury concentrations
Researchers from the SCRIPPS, the Stockholm Natural Museum and the Mediterranean Institute of Oceanography show the importance of sea ice composition on methylmercury budgets

Estimating Atmospheric Trace Element Deposition Over the Global Ocean
A recently developed method based on the natural radionuclide beryllium-7 has provided a means to estimate the bulk atmospheric trace element deposition velocity

Pre-announcement of 3rd GEOTRACES Summer School
