Science Highlights

Particulate Trace Element Export in the North Atlantic Ocean

Authors estimated particulate trace element export fluxes and residence times in the upper North Atlantic Ocean

Surface water trace element and isotope data challenge dust flux models

They reveal that atmospheric deposition and not the physical transport, is the most important process supplying Fe to phytoplankton in the South Pacific Gyre

Dissolved iron and manganese fates reveal processes along the hydrothermal TAG plume

Authors 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
