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


GEOTRACES session at AGU Fall Meeting 2021

Submit an abstract before 4 August 2021!

GEOTRACES – plenary talk and sessions at ASLO 2021!

Do not miss Katharina Pahnke’s plenary talk and the two GEOTRACES sessions!

Virtual Special Issue “Cycles of trace elements and isotopes in the ocean – GEOTRACES and beyond” finalised

In addition to hosting the overview of the GEOTRACES Intermediate Data Product 2017, this special issue includes 30 other research articles that contribute to the International GEOTRACES mission.

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.

GEOTRACES endorsed as Ocean Decade Action

It’s official! GEOTRACES has been selected by the United Nations as one of the first endorsed Ocean Decade Actions.

UPDATE on the release of the GEOTRACES Intermediate Data Product 2021

GEOTRACES will release the IDP2021 in November alongside a series of science webinars!

Science Highlights

Controls of cadmium-phosphate systematic unraveled by Neural Networks and Ocean Circulation Inverse Model

Roshan and DeVries explore the similarities and contrasts between oceanic cadmium and phosphate cycles using an Artificial Neural Network mapping technique and Ocean Circulation Inverse Model.

Retreat of large marine-terminating glaciers may increase iron supply to surface waters

The findings demonstrate that glacial retreat and loss of ice-shelves may potentially result in increases in dissolved Fe supply to surface waters downstream of large marine terminating glaciers in future.

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 two increase over previous estimates having important implications for the global silicon cycle.
