Ocean acidification (OA) is expected to affect all nations through its influence on living marine resources. To understand ocean carbonate chemistry, seawater samples must be measured in two or more ways (ex. total dissolved inorganic carbon and total alkalinity).

This requires calibrating measurements with a reference material. For 30 years, one laboratory has produced the world’s supply of certified reference materials (CRMs). The COVID-19 pandemic has elucidated the lack of resilience; the lab has been unable to produce CRMs and shortages now compromise monitoring efforts and laboratory studies. This project aims to diversify production of CRMs and enhance their accessibility.
