CO2-in-seawater reference materials: yesterday, today, and tomorrow webinar

We welcome all who work on ocean acidification and ocean carbonate chemistry studies to attend. This is the first community engagement in a larger effort to increase the resilience of the production and distribution of ocean carbonate chemistry reference materials.

Abstract: In 1989, the US National Science Foundation awarded a grant to the Scripps Institution of Oceanography in preparation for the upcoming US JGOFS program. This grant was intended to enable the preparation of standards for the measurement of the CO2 properties of seawater that could be distributed to laboratories participating in the program so as to assure the production of a coherent data set from the differing labs and methodologies likely to be involved in the program. The model for this activity was the production and distribution of IAPSO Standard Seawater. This initial program was expanded through additional support from the US Department of Energy to enable international distribution to laboratories making CO2 measurement as part of the extensive joint ocean survey supported by JGOFS and  the WOCE Hydrographic Program.


Since then – and despite various setbacks – the Scripps Laboratory has produced such reference materials consistently, and has distributed them to a wide variety of laboratories around the world who are involved in ocean CO2measurements.  Since the early 2000s, and as a consequence of the growth in interest in studies of ocean acidification, this has grown to a substantial activity (~10,000 bottles of reference material distributed per year to a large number of laboratories in many different countries around the world). Throughout this time, Scripps has been supported in this activity by the US National Science Foundation alone (the US DOE withdrew in 1997).
