Dr Véronique Camille Garçon is a Centre National de la Recherche Scientifique (CNRS) Senior Scientist at the Laboratoire d'Etudes en Géophysique et Océanographie Spatiales (LEGOS). She graduated from University of Paris VII in Environmental Sciences (Energy and Pollutions) in 1981 and then became a post-doc fellow at MIT (Cambridge, USA) from 1982 to 1985. Recruited as an Early Career scientist at CNRS in 1985, she worked at Institut de Physique du Globe de Paris then moved down to Toulouse with a sabbatical stay at Princeton University in 1995-1996. Since January 2024, she is back at Institut de Physique du Globe de Paris as CNRS Emeritus Senior Scientist. Her research evolves around understanding and quantifying processes governing fluxes of carbon, oxygen and associated biogeochemical elements in the ocean, using in situ tracers observations, remotely-sensed data, coupled physical biogeochemical modeling and data assimilation technics. She is also deeply involved in oceanic biogeochemical climatic monitoring via electrochemical sensors development. To date, Véronique has authored over 190 peer-reviewed publications in highly cited journals, as well as ten book chapters and numerous communications in so called grey literature.

Throughout her successful scientific career, Véronique served on several national, regional and international committees, actively contributing to development and implementation of activities furthering the coherence of marine biogeochemistry observations and modelling. Her enthusiastic and proactive engagement in coordination was specifically relevant during her 10 years’ service for the Scientific Committee of the Surface Ocean Lower Atmosphere Study (SOLAS) project, of which she was the Chair until the end of 2017.

Veronique joined IOCCP SSG in 2018 as an Expert responsible for IOCCP activities around the most impactful biogeochemical EOV: Oxygen. Due to her earlier experience, Veronique is very familiar with the coordination process in marine biogeochemistry as well as the landscape of organizations, funding agencies, funding opportunities for coordination activities as well as interactions between individual projects and programs. All this makes Veronique a uniquely qualified person to embark co-leadership of IOCCP SSG, which she commenced in January 2021. Since taking on a GOOS Biogeochemistry Panel role in 2012, IOCCP has expanded our mission and activities to non-carbon biogeochemical EOVs. Having Veronique as a co-Chair is a positive confirmation of our dedication to EOV-wide coordination challenges for the benefit of the integrated ocean observing system aimed at achieving broader scientific progress and societal development.

Adrienne is an Oceanographer at NOAA’s Pacific Marine Environmental Laboratory (PMEL) and an Affiliate Assistant Professor at University of Washington’s School of Oceanography in Seattle, U.S.  Her research group focuses on advancing our understanding of the ocean carbon cycle and how it is changing over time. Her team maintains almost 40 moored autonomous time series around the globe in open ocean and coastal ecosystems that track air-sea CO₂ exchange and ocean acidification.  Her recent publications focus on characterizing natural variability and long-term anthropogenic trends using time series observations and models, uncertainty in observation-based CO₂ flux estimates, and modern-day exposure of marine organisms to corrosive carbonate chemistry conditions.  Adrienne also collaborates with her team and PMEL engineers on observing technology development.  This team was part of the first autonomous circumnavigation of Antarctica in 2019 and has transferred two autonomous air-sea pCO₂ observing technologies to industry and nonprofit partners.

From 2015 to 2021 Adrienne served as co-chair of the Biogeochemistry Task Team of the Tropical Pacific Observing System 2020 (TPSO2020): a groundbreaking effort that implemented for the first time the Framework for Ocean Observing’s user-driven and variable-focused design.  She also serves on the steering committees of OceanSITES, Prediction and Research Moored Array in the Tropical Atlantic (PIRATA), and the Global Ocean Acidification Observing Network (GOA-ON). She is active in the community data quality control efforts of the Surface Ocean CO₂ Atlas (SOCAT) and research capacity building efforts through the United Nation’s Sustainable Development Goal 14.3.1 Indicator Development Expert Group.  She has also developed trainings on monitoring strategy design and data quality control and management best practices with GOA-ON, the IOC-UNESCO and other partners.

Adrienne is incredibly passionate about mentoring the next generation of oceanographers, especially those underrepresented in the ocean sciences and also has experience in science communication and policy. Adrienne’s dedication to marine biogeochemistry will no doubt help IOCCP provide our services to the community via a variety of well-designed and efficiently implemented activities.

Maribel García-Ibáñez is a Tenured Scientist (Científica Titular) at Instituto Español de Oceanografía (IEO-CSIC) in Palma, Spain. She earned her PhD in 2015 under the supervision of Prof. F.F. Pérez from Instituto de Investigaciones Marinas (IIM-CSIC) of Vigo (Spain). Her PhD research focused on understanding the inorganic carbon cycle in the North Atlantic Ocean, in particular its anthropogenic perturbation. The results of her PhD, along with other works that she co-authored, highlighted the role of the water mass formation and transformation in the relatively fast acidification rates of the intermediate and deep waters of the Subpolar North Atlantic.

Maribel is an interdisciplinary oceanographer with a deep interest in the link between chemical and physical oceanographic processes and their implications in the marine environment. Her background includes exhaustive knowledge of the ocean inorganic carbon cycle and water mass circulation, formation, and transformation in the North Atlantic Ocean, the Southern Ocean, and the Mediterranean Sea. Maribel has participated in several cruises, where she has sampled, measured, and quality-controlled seawater CO2 system variables, as well as managed the databases until their submission to data repositories. Her work experience includes leakage detection in offshore reservoirs related to carbon capture and storage (CCS), characterization of indicator dyes used to measure seawater pH and exploration of the internal consistency of the measurements of the seawater CO2 system, as well as characterisation of the processes affecting the carbon uptake in the Southern Ocean and analysis of tipping points for North Atlantic cold-water corals. Maribel collaborates with the Ocean Carbonate System Intercomparison Forum (OCSIF), with a goal to debate the nature of the internal inconsistencies of the ocean carbonate system data, advocate for needed research to resolve these problems, and provide guidance for data product assembly and documentation.

Within IOCCP, Maribel's role involves maintaining and enhancing a critical liaison between IOCCP and GO-SHIP, and perhaps more importantly will lead our struggle to build local and regional capacity to perform ocean interior observations based on GO-SHIP-approved best practices and data and metadata protocols and promote regular data submissions to the Global Ocean Data Analysis Project (GLODAP). Additionally, she is leading the discussions on designing a new, resilient production model of certified reference materials for the seawater CO2 system.

Gregor is a Head of Department of Marine Chemistry at the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) and holds a professorship for Marine Chemistry at the University of Rostock, where he teaches graduate courses in environmental chemistry and marine chemistry. As active chemical oceanographer and biogeochemist he leads a research group on Trace Gas Biogeochemistry focusing on the cycling and emissions of greenhouse gases (CO₂, CH₄, N₂O), including extensive research on the marine carbonate system. Gregor’s expertise includes greenhouse cycling in the open ocean, in coastal systems, and in the land-sea transition zone. He is also involved in research around development of assessment criteria and systematics for marine carbon dioxide removal (CDR), often bridging natural sciences and humanities.

Gregor is also heavily involved in research around improvements of marine instrumentation and interoperability of marine measurements and data streams. His group worked on extending spectrophotometric pH measurements towards lower (brackish) salinities, and Gregor played an active role in the SCOR Working Group 143 and activities leading to and resulting from an OCB Workshop on Oceanic CH₄ and N₂O. Gregor is also a PI of the instrumentation on the passenger ferry Finnmaid, which continuously monitors the partial pressures of CO₂, CH₄ and N₂O.

At IOCCP, Gregor will be responsible for coordinating the integration and homogenization of global observations related to oceanic and coastal measurements of N₂O and CH_4, including an update of the current EOV Specification for N₂O and driving the development of a sustainable observing network and related FAIR data stream for oceanic measurements of these important non-CO₂ greenhouse gases.

Dr. Dariia Atamanchuk is a Research Associate at the Ocean Science and Technology group at Dalhousie University, Halifax, Canada. During her early career research period, she has gained significant experience in sensor development, calibration techniques, characterisation of sensor performance, quality control and data handling. She has developed a strong network of collaborators amongst several national and international academic partners focused on multidisciplinary oceanographic studies using autonomous sensor platforms, as well as major industry partners focused on the development of in situ and sea-going instrumentation.

Currently, Dariia’s research activities are focused on the study of ocean biogeochemical cycling of EOVs (and beyond) using observations from autonomous platforms and sensors as primary tools. These include in situ and ship-borne observations of coastal environments (Scotian Shelf, KoljoFjord, Bedford Basin Time-Series) and the open ocean (Labrador Sea, North Atlantic) with respect to the carbon cycle (pCO₂, pH, TA), oxygen, nutrients (nitrate and phosphate), chlorophyll, bio-optical properties of seawater, velocity and more.

We believe that Dariia’s combined network of collaborators, working experience and expertise as sensor developer and user for various applications will significantly strengthen IOCCP’s ability to address the contemporary needs of our community concerning application and validation of new emerging tools in observing the global ocean’s interior. These can be achieved through e.g. inter-comparison studies of laboratory and autonomous sensor methods aiming to improve the methods and discover potential systematic errors, develop technical training opportunities, and contribute to standardisation of measurement methods for marine biogeochemical in situ observations.

Sana Ben Ismail received her PhD in 2014 jointly from the National Institute of Marine Sciences and Technologies (NIMST) in Tunisia and the Marine Environment Unit of the Mechanical-ENSTA Paris Tech. She now holds the position of Associate Professor of Oceanography at NIMST in Tunisia.

Since 2005 she is a member of the Marine Environment laboratory and the head of the research area "Hydrological and lagrangian observing system and comparison with model results in the Central Mediterranean” within that unit. She is responsible for the acquisition, processing and analysis of hydrological and biogeochemical data in the Tunisia-Sicily Channel and off the Tunisian coast. Sana is interested in the variability of water masses and circulation in the Mediterranean. She participated to more than 14 oceanographic cruises on board national R/v Hannibal and 2 international cruises on board Italian research vessels. Sana built a strong network of collaborators through participating in several regional and European research projects including SeaDataNet I and II, SeaDataCloud, Jerico Next and ENVIMED.

At IOCCP we will work with Sana to strengthen the local and regional network of biogeochemical observations in an environment where the observing and data management needs are not prioritized by most of the local stakeholders. Our activities will be initiated around southern Mediterranean community, but tools and practices developed will be applicable in other regions facing similar challenges.

He has undertaken research into the Biological Carbon Pump, the biologically mediated storage of carbon in the oceans interior which controls climate, land ocean carbon transfers and the oceanic uptake of CO₂ from the atmosphere.

At IOCCP Richard will lead our continuous efforts to create a much more robust surface ocean carbon observing system for monitoring ocean carbon uptake. A system that is capable of reporting annually on the state of the ocean carbon sink based on globally coordinated network of observatories, submitting FAIR data of known and feasible quality to recognized data management system approved by the global community.

Dr Julie Janssens is the Hydrochemistry Team Leader at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Hobart, Tasmania. She completed a PhD in sea ice biogeochemistry at the Institute for Marine and Antarctic Studies (IMAS). Her PhD combined fieldwork, lab work and numerical modelling to study iron enrichment in Antarctic sea ice. Since joining CSIRO in 2018, Julie specialised in the measurement of low-level nutrients, dissolved oxygen and salinity in coastal and open water environments. Her team at CSIRO provides specialised analytical chemistry services to Australia’s Marine National Facility (MNF) and to scientific research programs, as well as supporting the scientific operations of the MNF’s research vessel, RV Investigator.

Julie has an extensive expertise in leading nutrient measurement projects both onshore and at sea. She has led significant international initiatives, such as the International Nutrient Intercomparions Voyage (INIV) onboard RV Investigator, the Ocean Nutrients Symposium in 2023, and the Ocean and Coastal Nutrient workshop in 2024, to further improve nutrient measurement best practises. The INIV voyage was a world-first at-sea nutrient intercomparison along the GO-SHIP SR03 hydrographic section in the Southern Ocean, south of Tasmania, Australia. It brought together scientists and technicians from 14 laboratories across 12 different countries to evaluate the performance of international agencies in measuring ocean nutrients and understand the underlying variability in measurements. Discussions at the Nutrient Symposium covered analytical methods, new technologies, and data processing capabilities, alongside data applications.

With over 530 days of sea time and extensive experience working in marine biogeochemistry, Julie is passionate about advancing the field through collaboration, fostering inclusive professional development, innovative technologies, and capacity building. Her work aligns with IOCCP’s mission to enhance ocean biogeochemistry observations, ensuring that community needs are heard and addressed at an international level. As a member of the IOCCP Scientific Steering Group, she plays a key role in coordinating international nutrient-related efforts.

Steve Jones began as a software developer with a BSc in Computer Science from the University of Wales, Aberystwyth (2000) and a career in private industry. In 2007 he returned to university where he gained an MSc in Climate Change (2008) and a PhD in Marine Biogeochemistry (2012), both from the University of East Anglia. Following post-doctoral positions at the UEA and University of Exeter he moved to the University of Bergen, Norway in 2016, where he works as a software developer and data manager.

Steve’s career has covered many aspects of marine carbon cycle science. He has been on multiple research cruises to take ocean interior carbon measurements, and collected surface CO₂ measurements from instrumentation installed on a commercial ship. He developed a method for interpolating surface CO₂ measurements to obtain global estimates of air-sea CO₂ fluxes, contributing to the Surface Ocean pCO₂ Mapping Intercomparison. He has also contributed analyses to the annual Global Carbon Budget and the RECCAP synthesis.

Steve’s current focus is developing software to support moving marine biogeochemical observation onto a more operational footing, standardising and automating data processing, quality control and publication where possible and developing tools for those activities that cannot (or should not) be automated. Much of his work benefits the European Research Infrastructure: Integrated Carbon Observing System – Ocean Thematic Center, directly supporting the scientists and engineers collecting data. He is also involved in data publication through projects such as SOCAT, GLODAP, EU Copernicus and EU ENVRI-FAIR, working to ensure that data is as open and accessible as possible.

Steve will continue IOCCP’s mission to help the whole community produce and use FAIR data of known quality as smoothly as possible.

Nico Lange completed his PhD at GEOMAR, Germany in 2023 and is currently a post-doc at NORCE in Bergen, Norway. He focuses on the manifestation, and impact of data synthesis products in the marine biogeochemical data landscape. As a key member of the Global Ocean Data Analysis Project (GLODAP) Reference Group, Nico is responsible for the advanced quality-control, and processing of data since 2018. He will continue to fulfil this role for the planned GLODAPv3.  More recently he started leading the international community effort “Synthesis Product for Ocean Time-Series” (SPOTS). The product brings together 12 internationally renowned time-series stations from around the globe to form the first synthesis data product with comparable data for biogeochemical ship-based time-series stations. Nico is also an active member of the Steering Committee of the Research Coordination Network for Marine Ecological Time Series (METS-RCN).

Despite his early career ocean professional status, Nico has been a very active member of our community for the past 3-4 years, and a combination of his leadership skills expressed around SPOTS activity, and relatively strong international exposure through GLODAP and METS-RCN allows IOCCP to further the community efforts aimed at formalizing the status of the ship-based time-series as a new GOOS (OCG) observing network. In his role as IOCCP SSG Expert for Synthesis Activities, Nico continues the long-standing IOCCP efforts to support existing data synthesis products as well as work with our community to assist with development of emerging data synthesis products around Oxygen EOV as well time series stations.
