The name Odyssey is a short-cut that stands for ``Ocean DYnamicS obSErvation analYsis'', and aims to bridge model-driven and observation-driven paradigms to develop, learn and analyse novel stochastic representations of ocean dynamics. The keyword ``Analysis'' has to be understood in terms of physical understanding, mathematical analysis and data analysis. The team involves 5 institutions, namely Ifremer, Inria, Institut Mine Telecom (IMT), University of Brest (UBO) and University of Rennes I (UR1). It is located both in Brest and Rennes
Covering more than 70% of earth’s surface, the oceans play key roles on the Earth climate regulation as well as for human societies. Yet, from wave breaking events to the movement of weather systems, the predictive capabilities of models notoriously quickly diminish with increasing lead times, even with the assistance of the world’s largest supercomputers. Despite ever-increasing developments to simulate and observe the coupled ocean-atmosphere system, our ability to understand, reconstruct and forecast the ocean dynamics remains fairly limited for numerous applications.
Our motivations are to help break this apparent logjam, and more specifically to bridge model driven and observation-driven paradigms to develop and learn novel stochastic representations of the coupled ocean-atmosphere dynamics. Methodological developments will be primarily implemented and demonstrated through three main objectives: (i) the analysis of mesoscale/submesoscale processes and internal waves, (ii) the monitoring of extremes ocean-atmosphere events and routes to rapid intensifications; (iii) the derivation of forefront deep-learning stochastic data assimilation techniques.
To address these challenges, we gather a unique transdisciplinary expertise in Numerical Methods, Applied Statistics, Data Science, Satellite and Physical Oceanography.
The research objectives of our group distribute in several challenges, exploring multimodal observations, air-sea exchanges and upper ocean dynamics, bottom boundary turbulent processes, stochastic flow representations, data assimilation and machine learning procedures. All these challenges take place or rely on principles and/or tools of three methodological contexts
Those contexts constitute the main set of methodological setups of our group. They distribute in several topical research challenges related to different issues on ocean dynamics involving observations, numerical models, learning or their coupling. We list them below.
