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).

We are pleased to inform you that the International Association for the Physical Sciences of the Oceans (IAPSO) is inviting applications for Best Practice Study Groups in the period 2024-2025. Each group will receive up to US$ 12,000 towards the costs of a meeting. Proposals should reach the IAPSO Secretary General via email by 15 November 2023. The proposers of Best Practice Study Group proposals will be notified by 31 December 2023 of the success or otherwise of their proposals.

We would like to draw your attention to a recently released document titled "Case for SOCAT as an integral part of the value chain advising UNFCCC on ocean CO₂ uptake" which aims to highlight the importance of consistent funding for SOCAT. The authors of the document request that funding agencies work with SOCAT to

1. provide emergency support over 2024-25 to ensure that the next two Global Carbon Budgets can contain an ocean element and
2. from 2026 transition SOCAT into a sustainable funding space based on nations underwriting its core elements, national hubs, a subscription-based model, or a mix of these.

We are pleased to inform you that GOA-ON's Ocean Acidification Week, a virtual multi-day forum to highlight ocean acidification research for sustainability initiatives around the world, will be held from 30 October to 03 November 2023. OA Week 2023 will highlight the latest research in ocean acidification as well as sessions on the UN Ocean Decade programme OARS - Ocean Acidification Research for Sustainability, the early career network ICONEC, the GOA-ON Regional Hubs, and much more. Session organization is currently underway and the detailed agenda will be announced closer to the date. For more information, please visit the OA Week 2023 website.

We are pleased to invite you for the first webinar in a series of insightful events exploring how the Horizon Europe OceanICU Project is working towards filling fundamental knowledge gaps about the Ocean Carbon processes, including human activity impacts on the ocean carbon cycle, and how we can develop and provide the right information and tools for industry, policy makers and society to better manage our environment.

The webinar will be held on 28 September 2023, at 14:00 CEST, moderated by Dr. Richard Sanders.
