Marion Gehlen - CT2 leader
Marion Gehlen is Research Director at LSCE (Laboratoire des Sciences du Climat et de l’Environnement), Gif-sur-Yvette, France. Her research focuses on (1) quantifying impacts of climate change, ocean acidification on marine biogeochemical cycles, ecosystems and associated feedbacks; (2) understanding recent and future evolution of the marine carbon cycle; (3) assessing the predictability of ocean biogeochemical state and its variability. Her approach combines biogeochemical modelling applied to process understanding and to the interpretation of observed, but also projected ocean biogeochemical states. She works across disciplinary borders by connecting omics and biogeochemical modelling, the development of high resolution physical-biogeochemical model systems for research and operational application, as well as the reconstruction of recent variability of the marine carbon system through innovative machine learning approaches.

Patrick Lehodey - WP3 leader
Patrick Lehodey holds a PhD in Marine Biology on the topic of deep sea fisheries over seamounts. He was then recruited at the Secretariat of the Pacific Community (Nouméa, New Caledonia) to investigate relationships between oceanography and Pacific tuna fisheries. With this objective, he started to develop the SEAPODYM model which integrates knowledge on micronekton and large oceanic predators. Nowadays, he leads the development of this model, and the micronekton model outputs are now provided also as new ocean variables in the European Copernicus catalogue. He was a member of the Scientific Steering Committee (2000-05) of the international programme GLOBEC (Global Ocean Ecosystem Dynamics) and co-chair of the GLOBEC/CLIOTOP (Climate Impacts on Oceanic Top Predators) until 2010. In 2006, he joined CLS (Toulouse) to develop the Marine Ecosystem Modeling activities for the management of marine resources under the combined impacts of fisheries, climate variability and climate change. Patrick Lehodey is author or co-author of more than 80 peer-reviewed scientific articles and book chapters dealing with tuna, fish population dynamics, micronekton, marine ecology, climate variability and climate change.
Within COMFORT he is the leader of WP3 - Impacts, risks, thresholds: Case studies. Patrick and his group at CLS investigate trends and potential tipping points due to projected climate changes in ocean ecosystems (using simulations of global zooplankton and micronekton functional groups) and also in global tropical tuna fisheries. To carry out their work, they use the SEAPODYM numerical model and data from the Copernicus marine service web.
