Goldschmidt 2022 – Call for GEOTRACES session proposals

Dear colleagues,

Please find below a call for session proposals for the Goldschmidt conference 2022 (submission deadline is September 30, 2021).

We kindly remind to those planning a GEOTRACES Session or Workshop for this conference to inform the International Project Office (IPO, before September 15, 2021.

We will share information about potential sessions or workshops on similar topics among the proponents so that they can coordinate their sessions before submitting their proposals rather than being required to merge sessions after the program committee has reviewed the session proposals. At the same time this will ensure that your session is publicised to the GEOTRACES community.

Thank you very much,



Dear colleagues,

We would like to encourage you to submit a session proposal for Theme12: Metals and Nutrient Cycling at the Goldschmidt conference 2022 in Honolulu (planned as hybrid meeting). Please find the theme description below.

Session proposals should be submitted online:

Submission deadline is September 30, 2021.

Looking forward to many exciting session proposals!

Nicholas Hawco, Alakendra Roychoudhury, Katharina Pahnke (theme 12 chairs)


Theme 12: Metals and Nutrient Cycling 
Joined in their participation in the chemistry of life, the journeys of essential elements separate as they travel through atmosphere, land and oceans. This coupling and uncoupling of the biogeochemical cycles of nitrogen, phosphorus, iron, sulfur, and other major and trace elements have sustained and constrained life on earth for billions of years. An even broader set of elements are now utilized to trace the fluxes that control these cycles. This theme will highlight the state of the art in describing and quantifying elemental cycles and their interaction with ecosystems and the solid earth. We welcome session proposals that focus on: 1) nutrient limitation of the marine and terrestrial biosphere, 2) past changes to nutrient cycles, 3) metal and nutrient fluxes across land-atmosphere-ocean interfaces, 4) microbial ecology and redox reactions in soils, sediments, and seawater, 5) plant-microbe-mineral interactions, 6) the mapping of elements and their isotopes in the oceans, 7) new perspectives on element cycles from genomics, transcriptomics and proteomics, 8) human perturbation of local and global biogeochemistry, 9) interactions between elements and evolution, 10) micro- and nano-scale aspects of global cycles, 11) modelling, laboratory, and culture studies that constrain biogeochemical fluxes, and 12) additional aligned topics.
