Stratégie d'établissement

This Tuition Track is fully in line with the engineering priority theme of the CNRS COP. Understanding the physical processes affecting the solid Earth and its interactions with the external envelopes requires the acquisition and exploitation (including modelling) of long-term observations of the Earth system. The recruitment of researchers who study the physico-chemical processes controlling the Earth's dynamics from observational data on the universe and the planet is a major challenge for the CNRS, and in particular for the Institut des Sciences de l'Univers (INSU), which leads this task of continuous observation of the planet in the framework of national observational actions involving networks of instruments deployed by the Observatoires des Sciences de l'Univers (OSU).
The physico-chemical processes that affect the Solid Earth, in particular its most superficial envelopes: the lithosphere and asthenosphere, control the heat exchanges and chemical fluxes between the Earth's interior and the external envelopes, shaping the Earth's surface. These processes are responsible for telluric hazards (earthquake and volcanism) and control the formation of georesources. These envelopes represent the outer boundary layer of the mantle convection system and are characterised by very high thermal and chemical heterogeneity. A better understanding of the processes that affect them is necessary to understand the dynamics of the Earth, the formation and evolution of the biosphere and the conditions of habitability of our planet, and to evaluate the telluric hazards and natural resources.
The SeisObsTS Chair aims to develop approaches to acquire and, above all, to exploit and model observational data on the structure and processes in the Solid Earth through multi-scale or multi-method seismological networks. Labelled via the National Observation Services (SNO) in the Solid Earth and structured within the RESIF - EPOS Research Infrastructure, seismological observations, in combination with other types of data (GNSS, etc.), are essential to our knowledge of the Earth. The CNRS-INSU is committed to perpetuating French excellence in geophysics by investing in instrumental resources and data distribution within RESIF-EPOS. This chair will reinforce this investment in terms of human resources. The challenge is to recruit a researcher/observer who is a driving force in the development of new approaches for the acquisition and exploitation of seismological data, in particular by valorising those coming from the national observation services and national instrument parks of the INSU Solid Earth Domain, which are all associated with the RESIF-EPOS Research Infrastructure. The objective is to take advantage of the national and European structuring of RESIF-EPOS to develop new methodological approaches and to use them to respond to major scientific and societal issues.

Stratégie du laboratoire d'accueil

The successful candidate will carry out research based on the exploitation and modelling of data from the National Observation Services supported by the RESIF-EPOS Research Infrastructure organised as a consortium of academic institutions and organisms and supported by the network of Observatories of the Sciences of the Universe (OSU). The possible hosted OSUs are : OSUG, EOST, OCA, IPGP. The possible hosted laboratories are : ITES, ISTerre, GeoAzur, IPGP

Stratégie Internationale

This chair is directly linked to the involvement of CNRS-INSU, OSU and laboratories in the European Research Area and European research infrastructures, in particular EPOS (European Plate Observing System). Major geophysical and seismological observation campaigns are often organised in the framework of research consortia with European and international partners. The seismological data archiving and distribution missions carried out within the framework of RESIF-EPOS have by essence a European framework. Thus, the candidate will be required to lead international partnerships in the framework of RESIF-EPOS and more generally around the exploitation and modelling of data, and the implementation of major seismological observation campaigns. The major seismological campaigns of the last 10 years and the development of new instruments and methods of analysis and modelling have created a pool of excellent young researchers who are likely to apply for this position.

Résumé du projet scientifique

This chair is dedicated to the understanding of the dynamics of the Solid Earth through the development of innovative methods of acquisition, analysis and modelling of seismological data. The objective is to better image the structures and thus constrain the physico-chemical processes controlling the dynamics of the solid Earth, in particular the crust and upper mantle and their coupling with the deep mantle and outer shells. Many scientific questions essential to our understanding of the Earth system can be addressed: Does the continental lithosphere retain a memory of the successive stages of its formation? Does this memory affect its dynamics? Is the lithosphere-asthenosphere boundary a purely thermal boundary or is it partly compositional, involving local partial melting? Why on Earth does mantle convection produce plate tectonics?
One way, not the only one, to reach this objective would be to complete the data from the permanent observation networks of SNO by temporary experiments in metropolitan France, overseas and in Europe using terrestrial and/or maritime instrumentation networks. The objective is to achieve suitable spatial and temporal resolutions to image the physical properties of the structures, in order to reveal the dynamics (thermo-mechanical states, role of internal and external fluids and forcing, etc.) at the relevant spatio-temporal scales. Thus, the candidate should have demonstrated his/her ability to develop innovative methods of acquisition, analysis and modelling of large volumes of multi-scale data to answer major questions on the dynamics of the Solid Earth. The ability to build and set up instrumental projects involving several partners at national and European level, as well as the ability to federate in these projects specialists from various Earth Sciences disciplines and/or other disciplines such as mechanics, mathematics, and new data science methods, such as artificial intelligence, will also be valued.

Résumé du projet d'enseignement

The teaching service within the university will be carried out in the form of an 'observation support mission' at the interface between the national observation services, the national parks of solid earth instruments and the national seismological data centre RESIF. This mission will aim to establish a policy to address the challenges of integrating, archiving and distributing very large volumes of data from new seismic acquisition technologies. A major issue is the systematic FAIRisation of observational data, which is associated with a high level of data quality requirements and services in close interaction with the OSU acquiring these data. This will include adapting procedures to archive and make large volumes of data available to the scientific community in an efficient manner, while improving the quality control of these data.

Environnement Financier

  • Total financé (dont package ANR) : 200 k€
  • Total du projet : 200 k€

Diffusion scientifique

The dissemination of the results will be done through world-class scientific productions: publications, patents, software... In addition, the results will be communicated to various  targets such as scientific communities, media, decision makers, general public, schools, etc., with an adapted calendar. Specific tools may  be developed such as websites, newsletters, meetings, international symposia, summer schools and conferences.

Science ouverte

The CNRS is developing a strong policy in favor of open science. Open science consists of making research results "as accessible  as possible and closed as necessary". As such, the CNRS aims to make 100% of the texts of publications resulting from the work of its laboratories accessible , in particular through deposit in HAL. The data produced must also be made available and reusable, except for specific restrictions. In addition, the guiding principles of individual evaluation have been revised in accordance with the DORA declaration, to be more qualitative and to take into account all facets of the researcher's profession.
The project is fully included in a research infrastructure whose labelling criteria include open science. The scientific output of the Chairholder will be fully open. The observational data produced will be fully compatible with the FAIR principles and will be carried by the RESIF national data centre. In addition, the Chairholder is expected to play a leading role in the implementation of innovative solutions for the distribution of large volumes of high quality open seismological data by the RESIF data centre.

Science et société

The relationship between science and society is now recognized as a full dimension of scientific activity. The project will develop this dimension in synergy with all the partners. The resulting research work will contribute to informing public decision-making. Participatory science initiatives may be initiated with actors from the project’s socio-economic and cultural eco-system .
The project is part of the CNRS's response to societal demand in the fields of natural hazards (monitoring of volcanoes, faults, landslides), mineral resources and the monitoring of strategic natural sites (e.g. aquifers, mines, geothermal and storage sites) subject to strong pressures due to climatic or anthropogenic forcing. It is therefore expected that the Chairholder will put in place a communication for the general public that is both meaningful in terms of these issues and that shows the scientific benefits of the observation activity.


The activity will be evaluated in particular on the basis of scientific production (publications, software, patents, etc.), on institutional and private partnerships formalized by contracts in particular, obtaining the necessary funding for large-scale international projects involving the analysis and modelling of large volumes of data and/or major data acquisition campaigns in the context of national and international calls for proposals , on international presence, on the promotion of work to  multidisciplinary scientific communities, on innovation and its transfer to society and on scientific dissemination to non-specialist audiences.
