We are happy to inform you that the registration is now open for the “Wepal-Quasimeme Workshop on Quality Assurance for inorganic carbon system measurements in context of ocean acidification monitoring”. The in-person workshop will be held on 18-20 March 2025 at the National Oceanography Centre, Southampton (NOC), UK.

Invited speaker: Andrew Dickson (MPL, Scripps Institution of Oceanography, Un. California, S.Diego)

Organising Committee: Helen Findlay (PML, GOA-ON), Amy Kenworthy (PML, GOA-ON), Sue Hartman (NOC), Steven Crum (Wepal-Quasimeme), Célia Bento (Wepal-Quasimeme), Koen Parmentier (RBINS), Marc Knockaert (RBINS)

Aims of the Workshop

1. To obtain a consistent approach to sampling, sample pre-treatment sample storage across the OSPAR contracting parties and AMAP countries for all four carbonate parameters (TA / DIC / pCO₂ / pH) and discuss sample preservation alternatives for HgCl₂. 
2. Discuss the key analytical techniques for all four carbonate chemistry parameter measurements; challenges, limitations and misconceptions affecting quality of results. The emphasis of the workshop will be on the parameters of TA/DIC/pH since these are likely to progress to the OSPAR CEMP but considerations will also be given to pCO₂. Discuss new more automated analytical techniques and measurements with sensors. Can these instruments provide data that obtain the weather or climate goals? Are the methods fit for purpose?
3. To obtain a consistent approach to the analysis of TA/DIC/pH, and correct use of reference materials/standards across the OSPAR and AMAP regions. 
4. The role of Quasimeme exercises in Quality assurance and Quality assessment. What are the results after 3 years AQ15 intercalibration exercises and what is the way forward?
5. Consider the limitations of reference materials across the OSPAR and AMAP regions i.e. salinity ranges, open oceans and coastal waters. New initiatives?
6. Address data quality objectives needed for various assessment purposes. GOA-ON identified the need for two different levels of data quality to ensure the availability of data and permit assessment of short-term variability as well as longer term trends, to be in line with recent years Accreditation Bodies.
