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.
