We are pleased to inform you about the 8^th WMO Workshop on the Impact of Various Observing Systems on Numerical Weather Prediction (NWP) and Earth System Prediction (ESP) that will be organized by WMO and hosted by the Swedish Meteorological and Hydrological Institute (SMHI) in Sweden, at the SMHI main office in Norrköping, on 27-30 May 2024. 

This upcoming 8th Workshop will focus on assessing the impacts of various observing systems in all Earth system domains on NWP. However, the scope will be extended to also encompass the impact assessment of the various observing systems, to other Earth system applications. We strongly encourage our community to look through the identified science questions relevant to marine biogeochemistry, especially S1.12-16 related to surface-based observing systems, and S2.9 related to space-based observing systems, and consider submitting an abstract. The abstract submission is open until 15 December 2023.

The Workshop will be held in a hybrid format (in-person and remote participation will be enabled), and will be conducted in English. Participation in the workshop is free of charge. There is no workshop fee. For more information, please visit the WMO website.

This is to let you know about the International Underwater Glider Conference scheduled on 10-14 June 2024 at Reveljen in Gothenburg, Sweden. This will be the 9^th EGO meeting, supported by the OceanGliders and the EuroGOOS Glider Task Team. The International Underwater Glider Conference aims to bring together leading researchers, innovators, and experts from around the globe to exchange knowledge, share discoveries, and foster collaborations in the exciting realm of underwater gliders. The conference promises to be an engaging platform for sharing insights, addressing challenges, and shaping the future of this field.

The call for abstracts will open in September 2023. If you have any questions, do not hesitate to contact This email address is being protected from spambots. You need JavaScript enabled to view it. or This email address is being protected from spambots. You need JavaScript enabled to view it.

We are pleased to inform you about the WMO-hosted workshop on “Observations within the Global Greenhouse Gas Watch", to be held at WMO Headquarters in Geneva on 3-5 October 2023. In our continuous effort to help our community strengthen the integration of the ocean carbon observing system as part of the global, cross-domain greenhouse gas monitoring, we would like to invite you to consider submitting an abstract and attending the workshop. Please note that the abstract submission and registration are already open and will close on 15 August 2023. More details about the topics to be discussed as well as the abstract submission form can be accessed from a dedicated Workshop website.

The Scientific Committee on Oceanic Research (SCOR) has announced that Emily Twigg has been appointed as the next SCOR Executive Director starting in June 2023. We would like to warmly welcome Emily, and very much look forward to working together for the benefit of the marine biogeochemistry observing community. You can read more about the new SCOR Executive Director from the article here. 

Emily replaces Patricia Miloslavich who will continue to serve SCOR until the end of June before starting her new position at the Australian Antarctic Division. We would like to express our sincere gratitude to Patricia for her outstanding commitment in serving the ocean science community and the support for IOCCP activities over the past several years. We wish her all the best and many successes in her new role.

We are thrilled to announce the release of Surface Ocean CO₂ Atlas (SOCAT) version 2023 which is now available on SOCAT website. SOCAT-based estimates have shown that the oceans take up a quarter of the CO₂ emissions from human activity, thus helping to mitigate climate change and providing a way to balance the Earth's carbon budget. The latest update of the community-led Surface Ocean CO₂ Atlas (www.socat.info), version 2023, has delivered 35.6 million, quality-controlled, in situ surface ocean fCO₂ (fugacity of CO₂) measurements collected between 1957 and 2022 with an estimated accuracy of <5 μatm.

The SOCAT synthesis products and the fCO₂ measurements in them are key for quantification of ocean CO₂ uptake at a monthly timescale, providing vital information for climate policy. However, the open ocean data collection effort has dramatically declined since 2017. SOCAT itself is at immediate risk upon losing its European data management team, while facing persistent funding shortfalls. The need for accurate knowledge of ocean CO₂ uptake and its variation now and in the future makes sustained funding of accurate surface ocean CO₂ observations and their synthesis imperative.

This is to let you know about the upcoming webinar on marine carbon dioxide removal. This webinar series presented by the Coastal Acidification Networks along the West Coast and Alaska as well as California Ocean Science Trust is intended to deliver the best available information on marine carbon dioxide removal (mCDR) and to explore concepts related to coastal ocean carbon. Through this series of co-designed webinars, participants will gain a better understanding of mCDR technologies, limitations, risks, and learn how to become engaged.

The webinar will take place on 23 June 2023, at 18:00 UTC. Please register here: https://register.gotowebinar.com/register/4220985988067491159

We are pleased to let you know about the upcoming GOA-ON's June webinar focusing on "Biogeochemical Studies in the Tropical and South Atlantic Ocean - from air-sea CO₂ exchanges to ocean acidification", hosted by the LAOCA regional hub. The webinar will take place on 27 June 2023 at 14:00 UTC and will feature presentations by:

• Michelle Graco (Instituto del Mar del Peru) will present the results of the main studies developed at the upwelling system of Perú focused on the oceanographic dynamics, the carbonate system and the implementation of a low-cost coastal marine observatory to monitor natural stressors and contribute to the SDG 14.
• Thiago Monteiro (Federal University of Rio Grande, Brazil) will present some of the main studies developed by the Brazilian Ocean Acidification Network (BrOA) in the western Tropical Atlantic, in the South Atlantic and in the Antarctic Peninsula, followed by an overview of our current knowledge of carbon chemistry, from air-sea CO₂ exchanges to ocean acidification.
• Carla Berghoff from the National Institute for Fisheries Research and Development in Argentina will moderate.
