On behalf of the U.S. Interagency Working Group on Ocean Acidification we would like to encourage you to participate in a community survey about your use of CO2-in-seawater reference materials. The survey will take 5-10 minutes and will help to gain a baseline understanding of how reference materials for the quality control of measurements of seawater CO2 system parameters are used and how to build resilience in their production and distribution. Currently, there is a single source of reference materials for total alkalinity, dissolved inorganic carbon, and pH in seawater and a calibrated HCl titrant for seawater alkalinity analysis (A. Dickson Laboratory, Scripps Institution of Oceanography, UC San Diego). A recent webinar by Andrew Dickson entitled, “CO2-in-seawater reference materials: yesterday, today, and tomorrow” (see the video recording) provides the context and motivation for this larger effort.
While the survey will not close on a specific date, we request that you complete it by May 21, 2021. Individual responses to this survey are confidential. Data from this survey linked to respondents’ identities will never be released publicly. Rather, data for public release will be presented in aggregated forms.
