We would like to draw your attention to the Ocean Carbon From Space Workshop organized by the European Space Agency (ESA), together with PML and support from NASA, to be held virtually from 14 to 18 February 2022. This workshop is being organised as the second workshop in the CLEO (Colour and Light in the ocean from Earth Observations) Series and is a contribution to the Committee on Earth Observation Satellites (CEOS) Work Plan on the Aquatic Carbon Application area, as endorsed by the CEOS Ocean Colour Radiometry Virtual Constellation (OCR-VC) founded within the International Ocean Colour Coordinating Group (IOCCG).

The main objective of the workshop is to bring together remote sensing scientists, field scientists and modellers around the common topic of ocean carbon, its pools and fluxes, its variability in space and time and the understanding of its processes and interactions with the earth system. The aim is to articulate a collective view of the current status, identify gaps in knowledge and formulate the scientific roadmap for the next decade, with an emphasis on evaluating where Earth Observations (EO) may contribute.

Abstract submission closes on 8 December 2021. Visit https://oceancarbonfromspace2022.esa.int to view the workshop sessions and other information.

We would like to let you know that the Global Carbon Budget 2021 has now been published. Please see the Global Carbon Project website (http://www.globalcarbonproject.org) to access the highlights, paper, data, and a number of figures, infographics and videos related to the annual update of the global carbon budget and trends for the year 2020, and projections for 2021. The corresponding paper is currently under review for the journal Earth System Science Data, available from here. You may also want to visit the Global Carbon Atlas http://www.globalcarbonatlas.org to explore in detail global and national CO₂ emissions.

We are happy to share with you the news that the G7 Future of the Seas and Oceans Initiative (FSOI) will collaborate with the IOCCP to develop an internationally agreed strategy for Surface Ocean CO₂ monitoring. The G7 and IOCCP collaboration was presented by the EU coordinator of the G7 FSOI Coordination Centre during a scoping workshop entitled "Ocean Carbon Capacities: Identifying priorities for collaborative action" held by the EU Joint Programming Initiative Healthy and Productive Seas and Oceans (JPI Oceans) on 21 October. The workshop focused on an action plan to develop a robust reporting system capable of understanding, evaluating and predicting ocean carbon uptake on an annual basis, placing these in the context of other ocean carbon sources and sinks, and reporting the results of this to the UNFCCC Global Stocktake 2023.

As part of the G7 FSOI Coordination Centre’s scientific and technical support to Global Ocean Observing System (GOOS), the Coordination Centre will work closely with the IOCCP, which acts as the GOOS Biogeochemistry Panel, to catalyse and facilitate the development of this strategy, building on existing observing programmes, data management structures and coordination bodies where possible. Such a strategy is needed to guide coordinated joint investment by governments to implement a global surface ocean CO₂ monitoring network capable of responding to the needs of global and regional policy drivers, including the UNFCCC Stocktake.

We would like to let you know about the call for new cruise submissions in preparation for the next annual release of the Global Ocean Data Analysis Project GLODAPv2.2022 data product. The GLODAP Reference Group is looking for cruises which have “carbon-relevant” data, i.e. have a finalized cruise bottle file with at least one:

• Inorganic sub-parameter (TA, DIC, pH, fCO₂) and/or
• Transient tracer (CFC-11, CFC-12, CFC-113, SF₆, CCl₄) and/or
• Carbon isotope (C¹³, C¹⁴)

The submission deadline for the next update is the 17 January 2022. For submissions or questions, principal investigators are encouraged to check the attached submission requirements document and contact Nico Lange (nlange[at]geomar.de).

The current product, GLODAPv2.2021, can be accessed from here: https://www.glodap.info

With COP26 just around the corner, you might be interested in the COP26 virtual Ocean Pavilion (https://cop26oceanpavilion.vfairs.com/) which is dedicated to showcase why the ocean matters in climate negotiations and to all life on our planet. It aims to increase knowledge, commitment and action for the ocean-climate nexus at the UN Climate Conference (COP26) in Glasgow, UK, this November. Registration for the Ocean Pavilion is free and will provide you with online access to live ocean events on November 1, 5, and 12 and on-demand content from 31 October - 12 November. All you will need is a Wi-Fi connection and a smart phone, tablet, or computer. Follow the registration link here.

This pavilion will aim to give you a real flavour of the ocean events and discussions at COP26 and will:

• Highlight important ocean events such as planned by the UNFCCC Secretariat under the Subsidiary Body for Scientific and Technological Advice (SBSTA), the Marrakech Partnership for Global Climate Action (MP-GCA), and VOP collaborating partners;
• Host panel sessions linking the ocean with the themes of the GCA events and SBSTA Ocean and Climate Change Dialogue themes to provide input to these discussions;
• Feature interviews with Party negotiators to gain insights on the status of discussions;
• Provide a gateway to ocean and climate stories from around the world through virtual exhibits, on-demand videos, reports and other online resources.

The Ocean Pavilion is coordinated by the Global Ocean Forum, Plymouth Marine Laboratory, Ocean Policy Research Institute (OPRI) of the Sasakawa Peace Foundation, the Oceano Azul Foundation, and the Intergovernmental Oceanographic Commission (IOC) of UNESCO under the Roadmap to Oceans and Climate Action (ROCA) Initiative, in collaboration with many other partners from across the globe.

Building resilience in the production and distribution of CO₂-in-seawater Certified Reference Materials (CRMs) continues to be an issue for the global marine carbon community because there is a single source of reference materials for total alkalinity, dissolved inorganic carbon, and pH in seawater and a calibrated HCl titrant for seawater alkalinity analysis (A. Dickson Laboratory, Scripps Institution of Oceanography, UC San Diego, USA). On 16 September 2021, as part of the Global Ocean Acidification Observing Network (GOA-ON) Week, IOCCP contributed to a dedicated session "Community Discussion around CO₂-in-seawater CRMs."

Apart from introducing the results from over 240 responses to the "CO₂-in-seawater Reference Material Community Survey" organized by the US Interagency Working Group on Ocean Acidification, the session informed and discussed about the status of CRMs and updates on resilience building globally and regionally in the US, Europe and for developing and lesser resourced laboratories. You can view the recorded webinar from the GOA-ON YoutTube Channel here: https://www.youtube.com/watch?v=8SJ2SW54Nhc

We are excited to let you know that IOCCP is co-organzing and co-sponsoring the 53^rd International Colloquium on Ocean Dynamics which will take place on 16-20 May 2022 in Liege, Belgium. The theme of the 53rd Liege colloquium is "Low oxygen environments in marine and coastal waters: Drivers, consequences, solutions." The event will investigate new developments and insights related to deoxygenation in open and coastal waters. The colloquium is a contribution to the Ocean Decade program Global Ocean Oxygen Decade (GOOD). Please see the Colloquium website for a complete list of sessions, including one on "Deoxygenation: observing and modelling" co-convened by Véronique Garçon, IOCCP Co-Chair. Véronique and Maciej Telszewski, IOCCP Director, represent IOCCP on the Colloquium Organizing and Scientific Committee.
