Description:

Reference materials (RMs) 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 RMs for total alkalinity, dissolved inorganic carbon, and pH in seawater and a calibrated HCl titrant for seawater alkalinity analysis (Dickson Laboratory, Scripps Institution of Oceanography). However, the US Interagency Working Group on Ocean Acidification (US IWG-OA) and various international organizations are working to increase the resilience of production and distribution of CO2-in-seawater RMs. In this community discussion session, participants will receive status updates from American & European. Additionally, the US IWG-OA will share its findings from the “CO2-in seawater Reference Materials Community Survey” that was distributed earlier this year. There will be an extended Question & Answer panel discussion, and audience members will be given ample time to ask questions and share their thoughts.

Ocean Acidification Week 2021 was sponsored by the following organizations:

(1) GOA-ON, the Global Ocean Acidification Observing Network,

(2) NOAA, the United States National Oceanic & Atmospheric Administration,

(3) IAEA OA-ICC, the International Atomic Energy Agency – Ocean Acidification International Coordination Centre, and

(4) IOC-UNESCO – the Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific and Cultural Organization
