IUGS-CGGB 2021 Workshop on:  Extracting, visualising and interpreting structure in geochemical data through compositional data analysis (CoDA)

The workshop material will be found in the Workshop web page



As the World is still suffering from the Covid-19 pandemic only a few conferences will be posted on this web-page.  All members of the IUGS Commission will be informed by E-mail about pending conferences during 2022.


EGU General Assembly, Vienna | Austria | 23–27 May 2022

Co-organised by GI2/GMPV1
Convener: Marthe Klöcking Co-conveners: Alexander Prent, Lucia Profeta, Geertje ter Maat, Kirsten Elger

THIS IS AN INTERESTING SESSION FOR APPLIED GEOCHEMISTS.  IF ANY MEMBER OF THE IUGS Commission on Global Geochemical Baselines plans to attend the EGU General Assembly please get in touch with Anna Ladenberger ( and Alecos Demetriades (

Globally, geoscience and research analytical laboratories collect ever increasing volumes of data: an acute challenge now is how to collate, store and make these data accessible in a standardised, interoperable and machine-accessible form that is FAIR. Many solutions today are bespoke and inefficient, lacking, for example, unique identification of samples, instruments, and data sets needed to trace the analytical history of the data; and there are few community agreed standards to facilitate sharing and interoperability between systems.

The push for a solution is being driven by publishers and journals who increasingly require researchers to provide access to the supporting data from a trusted repository prior to publication of manuscripts or finalisation of grants. We urgently need community development of systems to facilitate easy and efficient management of geoanalytical laboratory data. We need to address the lack of global standards, best practices and protocols for analytical data management and exchange, in order for scientists to better share their data in a global network of distributed databases. Buy-in from users and laboratory managers/technicians is essential in order to develop efficient and supported mechanisms.

This session seeks a diversity of papers from any initiative around the world that organises and structures sample/field metadata and research laboratory data at any scale to facilitate sharing and processing of geoanalytical data. We welcome papers on data and metadata standardisation efforts and papers on data management and systems that transfer data/metadata from instruments to shared data systems and relevant persistent repositories. Efforts on how to collate, curate, share and publicise sample/data collections as well as papers on the social dynamics of building sharing systems/frameworks are also welcome.
