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
Dissolved gallium unravels Pacific and Atlantic waters in the Arctic Ocean
Whitmore and co-workers demonstrate that the dissolved gallium distribution provide a better water source deconvolution than the nutrient tracers
Precise estimate of the mercury export from the Arctic to the Atlantic Ocean
Using new observations acquired during GEOTRACES Arctic cruises, a refined arctic mercury budget has been established
