REMINDER – Goldschmidt 2022 – Call for GEOTRACES session proposals

Dear colleagues,

We would like to remind you that the submission deadline for session proposals for the Goldschmidt conference 2022 in Honolulu is coming up soon.

The deadline for session proposals is September 30, 2021.

Please consider submitting a session proposal for Theme 12: Metals and Nutrient Cycling (see summary below)

Session proposals should be submitted online:
(Please remember to inform the GEOTRACES IPO – – to ensure that your session is publicised to the GEOTRACES community!)

We are looking forward to your contributions!

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.
