MarChemSpec at the Ocean Sciences Meeting

Those will long GEOTRACES memories will be aware of the chemical speciation modelling initiative that began as SCOR Working Group 145. This initiative has now transitioned to be a part of the IAPSO/SCOR/IAPWS Joint Committee on the Properties of Seawater.

At Ocean Sciences 2024 the group will release version 1.1 of the software product. The software is freely available via the website, and can be run standalone or called from MATLAB or Python. New for version 1.1 is the ability to fix any two of the CO2 system parameters.

Project leaders David Turner and Simon Clegg will present posters on MarChemSpec applications to marine carbon dioxide removal (mCDR) (CM24A-1140) and trace metal complexation (OB34C-0880) at OSM24. Meet them at their posters and visit the Ocean Carbon & Biogeochemistry (OCB) Exhibit Booth (BOOTH 512, OSM Exhibit Hall) to test drive the new software. David and Simon will be at the meeting all week, and their availability at the OCB booth is likely to be broadly:

  • Tuesday: 10 am – 6 pm
  • Wednesday: 10 am – 4 pm
  • Thursday: 10 am, 12 noon – 1 pm
