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.

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 22nd webinar will take place on 13 September 2023, at 17:00 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.

This is to let you know that the 11th International Carbon Dioxide Conference (ICDC11) will be hosted in Manaus, Brazil from 29 July to 2 August 2024, at the Vasco Vasques Convention Center. ICDC11 was originally planned for 2021 but was delayed due to the COVID-19 pandemic and subsequent logistical challenges. Manaus was selected to allow visitors to experience a taste of the Amazon, a region central to understanding the global carbon cycle.

Taking place in the heart of Amazon, amidst an El Niño, and on the heels of the first Global Stocktake, ICDC11 represents an important opportunity to consider how improved understanding of terrestrial and oceanic carbon fluxes can inform carbon management and mitigation policy. The conference will provide the platform to have a dialogue between communities focused on understanding our latest science, technological capabilities and the needs, priorities and open questions of the policy and management communities.

We are pleased to inform you about releasing the updated version of the OOI Biogeochemical Sensor Data Best Practices and User Guide. The newest Version 1.1.1. after being reviewed by the biogeochemistry community, was endorsed by IOCCP as GOOS Biogeochemistry Panel of Experts. The current version is available here: https://repository.oceanbestpractices.org/handle/11329/2112.2

The Ocean Observatories Initiative (OOI) Biogeochemical (BGC) Sensor Data Best Practices and User Guide is the result of an NSF-funded (OCE2033919) grass-roots community effort to broaden the use of OOI biogeochemical sensor data and increase community capacity to produce analysis-ready data products. The guide includes five chapters: The Introduction (Chapter 1) provides information on the OOI program, including data access, processing, and recommended end user QA/QC relevant to all OOI biogeochemical sensors, and Chapters 2-5 cover the following groups of BGC variables and associated sensors: Dissolved oxygen, nitrate, carbonate chemistry, and bio-optics.

The EU H2020 project EuroSea has made fantastic contributions to the work of marine biogeochemistry observing and modelling communities, and IOCCP has been thrilled to be part of it over the past 4 years. We are excited to invite you to join the upcoming EuroSea Symposium on Ocean Observing and Forecasting, a high-level event bringing together national and international stakeholders from policy, science, and industry. This symposium will take place on 21 September 2023, at the IOC/UNESCO Headquarters in Paris.

Registration for the event is currently open and will close on 5 September 2023. For more information on how to register, please visit the website: https://events.geomar.de/event/233/. Please read the Symposium Agenda.

We are pleased to inform you about the call for abstracts for the Ocean Sciences Meeting 2024, which will be held in New Orleans, USA, on 18-23 February 2024. We encourage you to become familiar with the sessions relevant to the marine biogeochemistry community. You will find the list of accepted sessions for OSM24 here: https://agu.confex.com/agu/OSM24/prelim.cgi/ModuleProgramBook/0. Below we provide links to selected topics of potential interest. The abstract submissions deadline is 13 September 2023, 23:59 EDT / 03:59 +1 GMT. For further details, please visit the OSM24 website.

The Ocean Sciences Meeting (OSM) is the flagship conference for the ocean sciences and the larger ocean-connected community. Every two years, the Ocean Sciences Meeting unifies the oceans community to share findings, connect scientists from around the world, and advance the impact of science. The Ocean Sciences Meeting 2024 is co-sponsored by the American Geophysical Union (AGU), the Association for the Sciences of Limnology and Oceanography (ASLO), and The Oceanography Society (TOS).

We are pleased to inform you about the upcoming International Digital Twins of the Ocean Summit 2023, which will be held in Xiamen, China on 9-12 November 2023. Taking the great arena of 2023 World Ocean Week in Xiamen, the DITTO Summit 2023 will be co-organised by the Fujian Ocean Innovation Center and State Key Laboratory of Marine Environmental Science (Xiamen University), and to gather global participants with themes focusing on sharing the latest knowledge about DTOs and discussing future actions on advancing and applying them. The abstract submission's deadline is extended to 20 August 2023. For further details please read the Third Announcement.
