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


Special Issue on Marine Particle Chemistry is complete!

Six papers in this collection report on results from the GEOTRACES programme. Together, they help to fill critical gaps in the knowledge of the role of particles and elements in marine biogeochemical cycles.

Release of version 1 of FeMIPeval ocean model assessment tool

FeMIPeval is designed to facilitate the assessment of ocean iron cycle models against GEOTRACES intermediate data product 2017 (IDP2017) via a set of different skill metrics in a systematic manner.

Compilation of dissolved organic matter (DOM) data obtained from global ocean observations from 1994 to 2020

Science Highlights

Updated compilation of the global continental and marine lithogenic neodymium isotopic measurements

This new compilation and gridded datasets offer a concrete way forward to improve the application of Nd isotopes as a useful tracer of ocean circulation.

Neodymium concentrations and isotopes help disentangling Siberian river influences on the Arctic Ocean

Paffrath and co-autors followed the relative contributions of the main Siberian rivers to the waters of the Transpolar Drift using neodymium parameters.

A new and more quantitative atlas of the deep-sea burial fluxes of major and trace elements

Among other findings, authors find that the new opal flux is roughly a factor of 2 increase over previous estimates having important implications for the global silicon cycle.
