We would like to let you know that on Thursday, 20 May 2021, 11:00-12:00 UTC, the European Marine Board (EMB) will host a webinar on Big Data and the value chain of ocean CO₂ measurements. The webinar will build on the science presented in EMB's 6^th Future Science Brief on Big Data in Marine Science, and will be presented by one of the co-authors of this publication, Dr. Dorothee Bakker (short bio).

The webinar will be hosted on ZOOM, for which you can register via this link. The recording of the webinar will also be made available on the EMB YouTube page.

We are excited to announce that IOC-UNESCO has just published the "Integrated Ocean Carbon Research: A Summary of Ocean Carbon Knowledge and a Vision for Coordinated Ocean Carbon Research and Observations for the Next Decade", a report which sets out to accomplish the vital task of indicating the current gaps and future directions for the integrated ocean carbon cycle research.

IOCCP was one of the five international research and coordination programmes on ocean-climate interaction, which have been working together since 2018 in the IOC Working Group on Integrated Ocean Carbon Research (IOC-R). The other organizations are: the Integrated Marine Biosphere Research Project (IMBeR), the Surface Ocean Lower Atmosphere Study (SOLAS), the Climate and Ocean Variability, Predictability and Change (CLIVAR) project and the Global Carbon Project (GCP).

The report presents a synthesis of the state of knowledge about the oceans’ role in the carbon cycle and points to the way ahead. Its objective is to provide decision-makers with the knowledge needed to develop climate change mitigation and adaptation policies for the coming decade. It also emphasizes the importance of scientific knowledge to the taking of informed decisions within the United Nations Framework Convention on Climate Change in order to achieve the goals of the Paris Agreement and build more resilient societies. Through continued collaboration amongst IOC-R WG co-conveners, we hope to develop an innovative joint programme of medium- and long-term integrated ocean carbon research to fill the gaps in this field.

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.
