The Starfish Team

The 2025 Ocean Barometer is authored by a multidisciplinary team of leading experts in Oceanography, marine science, and policy. Representing renowned institutions across France and Europe, our authors combine their scientific expertise and commitment to Ocean stewardship to deliver up-to-date, science-based and accessible insights. Together, they ensure the barometer reflects the latest knowledge and supports general awareness and informed action for our Ocean’s future.
The Project Initiators

The concept of the Starfish Barometer was developed and coordinated by Pierre Bahurel and Marina Lévy, with the support of Patrick Vincent.
Pierre Bahurel, Mercator Ocean International Pierre Bahurel is Director General of Mercator Ocean, the European centre for global Ocean monitoring and forecasting. He is committed to digital Oceanography serving Ocean sustainability, as achieved with the EU's Copernicus Marine. Under his leadership, Mercator Ocean is becoming an intergovernmental organization, advancing Digital Twin Ocean infrastructures, and mobilizing the international prediction community.

Marina Lévy , Sorbonne Université, LOCEAN-IPSL, CNRS/IRD/MNHN
Dr. Marina Lévy, Distinguished Research Director at CNRS and Ocean Advisor at IRD, is an internationally recognized expert on ocean turbulence’s impact on marine ecosystems and climate.
A CNRS bronze medallist, she pioneers interdisciplinary research bridging ocean physics, biogeochemistry, and biodiversity, while actively raising public and corporate awareness on ocean challenges.

Patrick Vincent, Science Advisor to the Special Envoy of the President of the French Republic for the United Nations Ocean Conference Dr. Patrick Vincent is a recognized expert on Ocean observation from space and his dedication to space altimetry before leading IFREMER as the Deputy General Manager. Since 1995, being part of the Mercator Ocean initiating team, he participated actively in the development of operational Oceanography.
The Authors

The 2025 Starfish Barometer draws on contributions from a multidisciplinary team of leading scientists in oceanography, marine science, and policy, and was overseen by the international scientific committee of the One Ocean Science Congress (OOSC, Nice, June 3–6, 2025).
Bruno Blanke - LOPS-IUEM, UBO/CNRS/Ifremer/IRD Dr. Bruno Blanke, CNRS research director at LOPS in Brest, specializes in Ocean circulation and developed the ARIANE diagnostic tool. Formerly Deputy Scientific Director for the Ocean-Atmosphere domain at CNRS-INSU, he now assists the CNRS Lead Scientific Coordinator for Sorbonne University and co-leads the national Priority Research Program "Ocean & Climate".

Joachim Claudet - CNRS, PSL-EPHE-UPVD, CRIOBE Dr. Joachim Claudet, researcher director and Ocean advisor for CNRS, has extensive experience in Ocean sustainability science, using place-based case studies to inform management, or regional to global meta-analyzes to impact policy. His work is highly interdisciplinary, bridging ecology, social sciences, and governance to develop actionable knowledge for decision-makers.

Patrick Guillotreau - MARBEC, IRD/Ifremer/CNRS/Université Montpellier Dr. Patrice Guillotreau, formerly professor of economics at Nantes University for two decades, is senior researcher at IRD. His research lies on the economics and management of Oceanic fisheries and the blue economy more generally, with special focus on the vunerability of small island developing states to global changes.

Audrey Hasson - Mercator Ocean International Audrey Hasson is the GEO Blue Planet executive director. Hosted by Mercator Ocean International and funded by the European Union, the GEO Blue Planet initiative promotes the use of Ocean observations for the benefit of society. She holds a Ph.D. in physical Oceanography, specialized in remote sensing.

Claire Jolly – OECD 
Claire Jolly is Head of the Ocean Economy & Space Economy (IPSO Unit) at the OECD, leading research and analysis to inform evidence-based policy. With over 20 years’ experience in science, innovation, and economic policy, she is committed to advancing the long-term sustainability of ocean and space sectors.

Yunne Shin, MARBEC, IRD/Ifremer/CNRS/Université Montpellier, Montpellier, France 
Senior researcher at IRD, Yunne Shin is an expert in cutting-edge marine ecosystem modelling to support decision-making. She also develops transdisciplinary approaches, including participatory co-construction of scenarios and models, and arts and science co-creation.

Olivier Thébaud - AMURE, Ifremer/UBO/CNRS/IRD, IUEM Dr. Olivier Thébaud is a senior economist with Ifremer. He works as part of the AMURE joint research unit in marine social science, which he helped establish and directed. His research focuses on applying economics, in connection with other disciplines, to inform marine policy at national and international levels.

Adrien Vincent - IPOS Adrien VINCENT is a senior advisor to the International Platform for Ocean Sustainability (IPOS). Adrien is the founder of Albatros Advisory, an advisory boutique specialised in the Ocean sustainability space. He also advises the European Commission and the United Nations on their seaweed programs and works with Ocean impact funds and startups.

Karina Von Schuckmann - Mercator Ocean International Karina von Schuckmann is a senior advisor at Mercator Ocean. Her interest lies in understanding the role of the Ocean in Earth’s climate. She is the Director of the Copernicus Ocean State Report, IPCC author, member of the European Academy of Science and laureate of the French Academy of Science in 2023.
