We would like to let you know about the Ocean and Coastal Nutrient Symposium which brings nutrients technicians and scientists together to discuss analytical methods, new technologies, and data processing capabilities. The symposium will take place in Hobart on the 20th of June 2023, coinciding with the end of the International Nutrient Inter-comparison Voyage (INIV). Delivery of the event will be through a hybrid of virtual and in-person events.

This symposium will foster knowledge sharing, further develop laboratory best practices, and will improve the comparability of global nutrient datasets utilised by oceanographers, climate scientists, and biogeochemists. Discussions will cover new and emerging analytical, data processing and technical capabilities, including but not limited to methods and implementation of nanomolar nutrient analysis, robust data pipelines, miniaturisation, and the development of experimental non-bias procedures to increase comparability of nutrient datasets.

Submit your abstract for an oral presentation to Claire Mulhall at This email address is being protected from spambots. You need JavaScript enabled to view it. before the 14th of May 11:59 PM AEST.

We would like to let you know that the 8th WMO Workshop on the Impact of Various Observing Systems on Numerical Weather Prediction (NWP) and Earth System Prediction (ESP), will take place on 27-30 May 2024. Organized by The World Meteorological Organization (WMO), the workshop will be hosted by the Swedish Meteorological and Hydrological Institute (SMHI), at their headquarters in Norrköping, Sweden.

Workshop sessions will be structured around science questions related to ocean observations and beyond, several of which may be of particular interest to the marine biogeochemistry observing community (e.g. around the role of eularian and lagrangian observations in assessing and forecasting changing biogeochemical cycles). Please see more details on the proposed science questions below.

The online abstract submission will open in June 2023 and will remain open until the end of 2023. More details will follow in due course. If you have any  questions regarding the workshop, please contact organizers directly via the workshop email address: This email address is being protected from spambots.

We are pleased to inform you about the EURO-CARBON database initiative which aims to provide a baseline of sediment organic carbon levels on a European regional sea scale. If you have relevant carbon data from marine sediments, then please consider contributing your data to the EURO-CARBON database by 27 June 2023 at the latest. The database can potentially be updated periodically in the future to determine trends in organic carbon pools.

A data paper describing the database will be submitted to the journal Limnology and Oceanography Letters (Impact Factor = 8.5). All originators of submitted data and those that provide more than 40 individual carbon observations will be named co-authors on the resulting data article.

The Partnership for Observation of the Global Ocean (POGO) and Scientific Committee on Oceanic Research (SCOR) have announced that the POGO-SCOR Fellowship programme for 2023 is now open for applications. The scheme is designed to promote training and capacity development, leading towards a global observation scheme for the ocean, and is aimed at scientists, technicians, graduate students (preferably PhD) and post-doctoral fellows involved in oceanographic work at centres in developing countries and countries with economies in transition.

We are pleased to invite you to a series of workshops on surface ocean pCO₂ observations, synthesis and data products, which will be held on 6-9 November 2023 at Flanders Marine Institute (VLIZ), InnovOcean Campus, Oostende, Belgium.

Surface ocean pCO₂/fCO₂ (partial pressure/fugacity of CO₂) data products and air-sea CO₂ fluxes determined from them have become an important input in the quantification of the ocean carbon sink strength in the Global Carbon Budget (GCB) as well as in determining variability and trends of ocean acidification. There are however several aspects of the pCO₂ products and the fluxes based on them that are less well known, e.g. their sensitivity to data availability, method of interpolation/gap filling and the overall uncertainty in the air-sea CO₂ fluxes.

We would like to let you know about the GO-BGC/BGC-Argo Float Data Workshop that will be held August 21-23, 2023 at UMass Boston. The format of the workshop will be a hands-on exercise with open practices, inclusive participation, and thoughtful problem exploration. Attendees will generate research ideas utilizing Biogeochemical Argo float data and start working on projects as teams. This will be an active experience designed to familiarize participants with float data analysis techniques, illustrate scientific applications of float data, facilitate collaboration among diverse participants, and develop new tools for data analysis. Applications are now open. Evaluation of applications and travel award requests will begin on 20 May 2023.

We would like to let you know about the First Data Buoy Coordination Panel (DBCP) Mediterranean Training Workshop on Ocean Observations and Data Applications-Part 2 that will take place on 2-4 May 2023 in Tunis, Tunisia, and online. Guided by Sana Ben Ismail, IOCCP SSG member responsible for strengthening regional implementation, IOCCP has put together a session dedicated to Carbon & Biogeochemistry Observations as part of this hybrid-workshop.

Our session features presentations from and discussions with Maciej Telszewski (IOCCP Director), Marta Álvarez (CSIC, Spain), Sana Ben Ismail (INSTM, Tunisia), Abed El Rahman Hassoun (GEOMAR, Germany) and Houssine Nibani (AGIR, Morocco), covering a broad range of topics related to global and regional observing capacity, best practices, availability and use of data products, as well as data synthesis and coordination activities. We encourage any interested members of the community, especially from around the Mediterranean region, to join the workshop online through this MS Teams link. More information below and on the event page here. 

We are excited to let you know that IOCCP is looking for a new member to join its Scientific Steering Group (SSG) for terms beginning on 1 July 2023, to act as a leader responsible for maintaining and expanding IOCCP coordination activities within the theme of IOCCP: “Synthesis Activities.” 

To make inquiries and/or to submit your applications, please contact the IOCCP Project Office (This email address is being protected from spambots. You need JavaScript enabled to view it.). The deadline has been extended until 1 May 2023. Click below or download the attached full announcement.

We would like to update you on the outcomes from the World Meteorological Organization (WMO) International Greenhouse Gas Monitoring Symposium that took place at WMO Headquarters in Geneva on 30 January-1 February 2023.

The Symposium was targeted primarily at entities involved in greenhouse gas observations, modelling, data assimilation and related research in all domains of the Earth System. Symposium was held as one of the milestones in a wider attempt to build an internationally coordinated, operational global greenhouse gas monitoring system across all domains. This activity presents an opportunity for our community to further our own efforts towards a sustained, internationally coordinated routine greenhouse gas monitoring infrastructure with a broad group of stakeholders from scientific, operational, and policy-setting entities. 170 participants discussed current status and ways forward across a wide range of topics related to building such a monitoring system. The full Symposium agenda with most interventions available for viewing and download can be accessed from the Symposium website: https://community.wmo.int/en/meetings/wmo-international-greenhouse-gas-monitoring-symposium.
