GEOTRACES

An International Study of the Marine Biogeochemical Cycles of Trace Elements and Isotopes

News

Two synthesis articles resulting from the Joint GEOTRACES-PAGES Workshop available

They both assess the potential of a number of bioactive elements and their isotopes to inform on past ocean productivity.

New GEOTRACES webODV services released

The extractor has a fresher, clearer look as well as a new station selection feature by date and time. In addition, users can now plot and inspect their selected data.

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
