Pierre Daniel is a senior scientist in operational oceanography and numerical modelling and served as head of the marine drift modelling team in the Marine and Oceanographic Department of Météo-France until his retirement in September 2025. With more than 30 years of professional experience, his work focused on coastal and shelf-sea modelling, with particular emphasis on the development and implementation of operational forecasting systems for storm surges, oil spill drift, and maritime search-and-rescue applications. He is the author or co-author of approximately one hundred technical reports, peer-reviewed articles, and books, reflecting sustained contributions to both research and operational services. Since 1993, he has been an active member of expert groups of the World Meteorological Organization and UNESCO’s Intergovernmental Oceanographic Commission, contributing to international activities in marine emergency response. In recognition of his scientific and operational contributions to marine science, hydrography, and navigation, he received the André Giret Prize from the French Naval Academy in 2023.
