As you may know, the World Meteorological Organization (WMO) has been given the mandate by the 19th World Meteorological Congress (Cg-19, May 2023) to develop an Implementation Plan for the Global Greenhouse Gas Watch – G3W, a new Flagship of the WMO. A G3W implementation plan draft v1.0 with a G3W presentation v1.0 to guide the document navigation, are now available for public review.

We would like to share with you the Oostende Declaration in which the 100+ ocean experts and stakeholders call for concerted international and intergovernmental efforts to create a robust, resilient and sustainable surface ocean carbon observing system.

The text of the declaration is available here: Declaration on Operationalising the Surface Ocean Carbon Value Chain

We are pleased to inform you about the call for applications for the 2024 SCOR Visiting Scholars Program, which is open to any scientists who have time available to spend teaching and mentoring in a developing country for two weeks or more. The overarching goal of this program is to inspire, motivate, and inform students and faculty at developing institutions while also building long-term and sustainable collaborations and capacity. These scholarships are not intended to directly support research, although collaborative research may be an outcome of a visit. Applications from all regions of the world are welcome and the visit can happen at any time between February 2024 and December 2024.

Applications for the 2024 SCOR Visiting Scholars Program should be sent to This email address is being protected from spambots. You need JavaScript enabled to view it. by 29 December 2023 (up to 23:59 UTC). For further details, please read the call for 2024 SCOR Visiting Scholars.

Motivated by the calls for more integrated ocean carbon research, two EU-funded projects ECOTIP and EU4OceanObs have been supporting since early 2023 a multidisciplinary group of researchers in convening a new working group activity around ocean carbon sequestration data synthesis and modelling in the Arctic. Building on the results of an open community survey which engaged over sixty experts in Arctic carbon observations and modelling, both senior and early-career researchers from across Europe, North America and Asia, on 18-19 October 2023 the group organized an online workshop which gathered over 30 attendees tasked with identifying and designing biogenic data products to advance ocean carbon sequestration modelling in the Arctic. The event was also supported by the IOCCP, as part of the efforts to strengthen the integration across the biogeochemical modelling and observing interface.

On behalf of the GLODAP Reference Group, and hundreds of seagoing oceanographers who tirelessly have collected data all over the ocean, we are happy to announce the publication of GLODAPv2.2023.

The Global Ocean Data Analysis Project (GLODAP) data product provides access to quality controlled surface to bottom ocean biogeochemical data, with an emphasis on seawater inorganic carbon. GLODAPv2.2023 is an update of the previous version, with 23 additional cruises and includes measurements from more than 1.4 million water samples from the global oceans collected on 1108 cruises. The data for the 13 core variables have undergone extensive quality control, especially systematic evaluation of bias. The data are available in two formats: (i) as submitted by the data originator but updated to WOCE exchange format and (ii) as a merged data product with adjustments applied to minimize bias.

More details about GLODAP background as well as the v2.2023 release poster can be found here.

We are pleased to inform you about the upcoming Webinar on Ocean Deoxygenation organized by the Global Ocean Oxygen Network (IOC Expert Working Group GO₂NE). The 24th webinar of the series will take place on 20 November 2023, at 17:00 CET. The webinar will feature presentations by two early-career scientists, 20 minutes each, followed by 10 minutes moderated discussion sessions. Please register for the webinar here.

We would like to kindly remind you that the applications for the FAIR Data Practices for Ship-based Ocean Time Series Workshop are open until 24 October 2023. The workshop will be held on 9-12 January 2024 at the Bermuda Institute of Ocean Sciences (BIOS) and will bring together globally distributed ship-based ocean time series representatives who are interested in and committed to FAIR data practices with data managers and experts in semantic web technologies with the following objectives:

• Share and vet newly drafted biogeochemical and biological use cases for adoption by the broader METS community,
• Work with participating time series representatives to implement these use cases for their time series programs,
• Co-develop best practices for responsible use of ocean time series datasets (as a contribution to the Ocean Best Practices System repository),
• Share new findings and update recommendations on sampling and analytical protocols from the 2012 Bermuda Time Series Methods Workshop,
• Explore mechanisms (and identify champions!) for engaging broader stakeholders (managers, educators, etc.) in the use of ocean time series data sets,
• Start planning (and identify champions!) for an Ocean HackWeek for ocean time series data.

We are thrilled to inform you that the schedule for the upcoming OA Week 2023 is now available at http://www.goa-on.org/webinars/OaWeek2023/webinar.php This online event will take place from 30 October to 3 November 2023 and is designed to provide a platform for the ocean acidification community from across the world to exchange their latest findings through thematic sessions, plenary presentations and community engagement activities.

We would like to bring your specific attention to three sessions focused on issues closest to IOCCP mission:

• the "Sensors Session", planned for the first day of the OA Week, co-moderated by IOCCP Co-Chair Dr Kim Currie. During this session, you will hear from IOCCP SSG members: Dr Véronique Garçon (IOCCP Co-Chair), Dr Dariia Atamanchuk, and Dr Adrienne Sutton, among other speakers.

We are pleased to inform you about the upcoming webinar on ocean deoxygenation organized by the Global Ocean Oxygen Network (IOC Expert Working Group GO₂NE). The 23rd webinar of the series will take place on 11 October 2023, at 16:00 CEST. The webinar will feature presentations by a more senior and an early-career scientist, 20 minutes each followed by 10-minute moderated discussion sessions. Please register for the webinar here.

We would like to let you know about an open invitation to join an online workshop to discuss "Biogenic Data Products to Advance Ocean Carbon Sequestration Modelling in the Arctic." This 3-stage initiative, co-organized by EU H2020 ECOTIP and the EU4OceanObs projects, consists of a brief online survey, an online workshop to be held on 18-19 October 2023, and a final perspectives paper to be published based on the workshop outcomes. The deadline to complete the survey, which is a prerequisite to join the workshop, has been extended until early next week (4 October 2023).
