CO2-in-seawater reference materials community survey

Dear GOA-ON member,

The U.S. Interagency Working Group on Ocean Acidification is engaging in efforts to increase the resilience of the production and distribution of reference materials for the quality control of measurements of seawater CO2 system parameters. 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).

We are reaching out today to encourage your participation in a community survey about your use of CO2-in-seawater reference materials. Use this link to access the survey:

This survey is part of a larger effort, the first being a webinar by Andrew Dickson entitled, “CO2-in-seawater reference materials: yesterday, today, and tomorrow”. You can view a recording of that webinar here, with questions, conversation, and a pdf of the slides available here.

Data from this survey will be used 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. 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. 

This survey will take 5-10 minutes to fill-out. While the survey will not close on a specific date, we request that you complete it by May 21, 2021. 

Sincerely,
Michael Acquafredda, United States National Oceanic & Atmospheric Administration (NOAA)

Privacy statement:
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.

Timeline:
While the survey will not close on a specific date, we request that you complete it by May 21, 2021.

Rationale:
Reference materials are fundamental for accurate and precise measurements of seawater CO2 system parameters and research related to ocean acidification and oceanic carbon cycles. 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). The U.S. Interagency Working Group on Ocean Acidification is engaging in efforts to increase the resilience of the production and distribution of reference materials for the quality control of measurements of seawater CO2 system parameters. This survey is the second community engagement in this larger effort, the first being a webinar by Andrew Dickson entitled, “CO2-in-seawater reference materials: yesterday, today, and tomorrow” which can be viewed using Link #1 (below). A pdf of the slides and a conversation thread resulting from the webinar are available by accessing Link #2 (below).
