IOCCP Scientific
Steering Group

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.

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 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 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.

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.

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.

A large proportion of Keyhong’s academic contribution is related to DMS, with carbon cycle and statistical analysis filling the rest of his input. His international activity focuses on collaboration with project partners in the context of large-scale Southern Ocean monitoring.

Keyhong will take responsibility for coordination of IOCCP’s Time Series Efforts in Polar regions, with most focus on the Southern Ocean region, and will use his regional links to strengthen multilateral partnerships with the Asian biogeochemistry observational community, particularly with regards to ship-based and moored Time Series.

The Ocean Thematic Centre exists to support marine observing systems for high quality long term observations of greenhouse gases via the provision of standard gases, databasing, helping stations provide the highest quality observations and opening up access to new technology. Before joining ICOS-OTC Dr Sanders served as the Chair of the Ocean Biogeochemistry and Ecosystems group at National Oceanography Centre (NOC), in Southampton, UK, a position he has held since 2012. 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.

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’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 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.
