French research institute for the exploitation of the sea, Ifremer contributes, by its work and expertise, to the knowledge of the oceans and their resources, to the surveillance of the marine and coastal environment and to the sustainable development of maritime activities. Ifremer is a source of knowledge, innovation, monitoring data and expertise for the marine world, both in terms of public policy and socio-economic activity. It is the only structure of this type in Europe.
Founded in 1984, Ifremer is a public industrial and commercial establishment (EPIC), placed under the joint supervision of the Ministry of Higher Education, Research and Innovation, and the Ministry of Ecological and Solidary Transition.
• Presentation of the reception structure
The Laboratory of Ocean Physics and Satellite remote sensing (LOPS) is a Joint Research Unit placed under the supervision of the National Center for Scientific Research (CNRS), the French Research Institute for the Exploitation of the Sea (Ifremer), the Research Institute for Development (IRD) and the University of Brest (UBO). It is also a laboratory of the European University Institute of the Sea (IUEM). As a research unit, LOPS develops and participates in research programs in oceanography which contribute to the development of knowledge on ocean dynamics at different time and space scales and which study the relationships of the ocean with other compartments of the Earth system such as the atmosphere, sea ice and living organisms.
• Introduction of the position to be filled and its position in the organization chart
Within the scientific team "Ocean Scale Interactions" of UMR LOPS, under the authority of the head of the Ifremer laboratory "Deep Ocean and Ocean Scale Interactions", the recruited person will lead an original research project on fine scale dynamics in the deep ocean.
Compared to surface processes, the small-scale processes deep into the ocean are still little explored. It is nevertheless in the bottom layer that a significant part of the energy of the global ocean dissipates and that turbulent processes generate the mixture which will determine the physical and biogeochemical properties of the ocean water masses on a large scale.
These bottom boundary layers are an area of development of small-scale structures that are energetic and leading to significant mixing. But due to the difficulty of observing them so far, these small-scale processes in the deep ocean are still largely unknown.
Understanding the dynamics of the deep ocean is also an essential issue in order to better understand the problems linked to hydrothermal plumes and deep ecosystems and to assess the environmental impacts linked to the exploitation of mineral resources.
These bottom layer fine-scale processes are not taken into account in large-scale models. This partly explains the first-order uncertainties regarding the quantification of biogeochemical flows, and in particular of micro and macro-nutrients at the topography-water column interface. A better understanding of the processes of deep fine scales may allow, ultimately, the establishment of parametrization of physical and biogeochemical flows at the topography-water column interface which will benefit to large scale models, notably climatic, and to geosciences.
The LOPS "Ocean Scale Interactions" team has developed a great expertise in the turbulent dynamics of the oceans, based both on the theoretical analysis of the geophysical fluid dynamics, and on the development and use of suitable numerical models of those processes.
The recruited person, physical oceanographer, will specialize in bottom layer processes and current - topography interactions. The scientific objectives are to better understand the dynamics of fine scales in the deep layers of the ocean as well as the impact of these dynamics on ocean circulation on a larger scale and on physics-biology-lithosphere interactions.
The recruited person must carry out an original research project on the subject set out above. He / she can base his/her approach on a combination of theoretical models, in-situ data analysis with high spatial and temporal resolution, and numerical simulation.
He / she can be brought to contribute to data collection via the realization of dedicated campaigns and to propose technological developments preparing the future of in-situ measurements on fine scale in the interior and deep ocean.
To carry out his scientific project, he / she will pilot proposals, supervise doctoral and post-doctoral students, promote his research through scientific publications, presentations at international conferences, and communication to the general public.
