GEOTRACES is launching a new community effort to produce a set of global gridded climatologies for the trace elements and isotopes (TEIs) measured over the last two decades by the international GEOTRACES program. These climatologies, referred to as GEOTRACES State Estimates (GSEs) are intended to complement the Intermediate and Final Data Products released by the program, by providing global TEI distribution estimates that will broaden the reach of GEOTRACES data to new scientific communities. The GSE product will comprise model-predicted TEI distributions that are informed by and validated against the original GEOTRACES data, compiled into a single accessible archive.
The GSE for each TEI will be the result of a model intercomparison project (MIP), in which an ensemble of new and/or existing models are validated against observations from the GEOTRACES data products. Each MIP will be conducted by a collaborative team with expertise in the TEI of interest (including modelers and observationalists) in coordination with the GEOTRACES Data Management committee, who will oversee the GSE project and ensure that all MIPs are performed in a consistent manner.
That sounds great, how can I get involved?
- Talk to your colleagues and start to form a MIP team comprising modelers with expertise in modeling the TEI of interest, and observationalists who contributed data for that TEI.
- Watch this space: In late February 2026 (during the Ocean Sciences Meeting) we will publish a Best Practice Guide here with detailed instructions on how to conduct a GSE MIP.

- Contact GSE leads Tom Weber (t.weber@rochester.edu) and Zanna Chase (zanna.chase@utas.edu.au) if you have any questions.
