We wanted to share an exciting news that an open-access book Chemical Reference Materials for Oceanography: History, Production, and Certification has now been published in the Springer Oceanography book series.

The book explores the history, production, and certification of reference materials for essential parameters in oceanography and provides a comprehensive understanding of them to readers.

The organizers of the OceanObs’29 Conference invite us to apply to its Program Committee, an exclusive leadership role that will directly shape the vision, themes, and outcomes of this landmark event. They seek a broad range of ocean knowledge-holders, including classical ocean observation experts and Early Career Professionals (ECPs), indigenous representatives, and thought leaders - spanning science, engineering, policy, and industry to guide this effort.

The OceanObs’29 Program Committee applications are open until 31 May 2025. It's important that marine biogeochemistry is adequately represented on the Program Committee and we hope that some of you will consider taking this opportunity to shape the next decade of ocean science and observations.

We would like to remind you that the call for SCOR working groups is open until 16 May 2025. The SCOR Secretariat invites proposals for new working groups to commence activities in late 2025. SCOR typically supports 1-3 new working groups annually, pending availability of funds and the outcome of the proposal review.

We are happy to inform you that the registration is now open for the “Wepal-Quasimeme Workshop on Quality Assurance for inorganic carbon system measurements in context of ocean acidification monitoring”. The in-person workshop will be held on 18-20 March 2025 at the National Oceanography Centre, Southampton (NOC), UK.

IOCCP in close collaboration with our global partners, continues to foster the integration of efforts around quality assurance for inorganic carbon measurements with the global metrology systems so that those measurements are metrologically traceable to the International System of Units.

We would like to inform you about the upcoming webinar on "Advancements in Biogeophysical 4D reconstructions: New methods development and exploitation of existing products for scientific investigations" organised by SCOR Working Group 168 (4D-BGC) on 26 November 2024, at 12:00 pm CET.

During the OA Week on 18-22 November, the ocean biogeochemistry community will have a great opportunity to discuss the most challenging issues around ocean acidification. This year we’d like to specifically encourage you to participate in a community discussion on “Building capacity in physical chemistry for oceanography: how to address the emerging skills gaps”.

We are happy to share that the call for abstracts for the One Ocean Science Congress is now open until 14 November 2024, 13:00 CET. The One Ocean Science Congress (OOSC), organised by CNRS and IFREMER, will be held in Nice, France, from 4 to 6 June 2025. It is a UN Special Event serving as the scientific foundation of the Third United Nations Ocean Conference (UNOC3).

We are excited to let you know that the Surface Ocean CO₂ Observing Network (SOCONET) alongside the Fishing Vessel Observing Network (FVON) and Science Monitoring And Reliable Telecommunications (SMART) Subsea Cables became a Global Ocean Observing System emerging network. Find out more on these 3 new additions from an article published on the GOOS website.

We are thrilled to let you know that the Global Greenhouse Gas Watch (G3W) Implementation Plan has been endorsed!

Thanks to the excellent work of the Joint Study Group on WMO Greenhouse Gas Monitoring (SG-GHG), the G3W Implementation Plan has been approved by INFCOM-3 (the WMO Technical Commission for Infrastructure) in April 2024, and by EC-78 (the Executive Council of WMO) in June 2024. We all owe a big Thank You to Adrienne Sutton (IOCCP SSG, NOAA, US) and Richard Sanders (IOCCP SSG, NORCE, Norway) for leading the writing of the Implementation Plan for the surface ocean CO2 (SOCONET and SOCAT). Other (SOCONET & SOCAT) contributors to the IP are Dorothee Bakker, Kevin O’Brien, Thanos Gkritzalis, Tobias Steinhoff, Bronte Tilbrook, Ronnie Noonan-Birch and Maciej Telszewski.
