CNAP | Concours 2022

Internal Earth Section

Our priority needs for CNAP IT positions are for the following service tasks:

• SNO ISDeform :SNO ISDeform: OSUG-ISTerre has been involved for several years in the scientific and technical development of radar space imagery processing services for ground deformation measurements, carried out by the Solid Earth « pôle de données » ForM@Ter at the national level and, at European level, through the EPOS (TCS Satellite Data) research infrastructure, and by SNO ISDeform for observations on the national territory and at the "Southern" partners.

The OSUG wishes to recruit a physicist in the framework of the SNO ISDeform.
The physicist will be in charge of the coordination of one or several actions of the SNO that are transversal to several OSUs. These transversal actions concern (a) the dissemination of data and products, (b) the implementation of processing chains and services on the computing infrastructures, the data processing and product validation, (d) communication, training and cooperation actions with IRD’s "Southern" partners. In addition, he/she will be responsible for the development and follow-up of structuring projects at the national, European and international levels involving the SNO (e.g., PIA, EGMS, OCRE, EPOS, ...). He will have to ensure the development of strong links with other SNOs (SNOV, RENAG, H+, Glacioclim), with the organizations involved in the SNO (CNES, IRD, IGN, BRGM) and possibly include other organizations. He/she will be the French point of contact for international scientific groups such as WInSAR, COMET, for the Form@ter scientific expertise center and for international cooperation programs (CEOS WG Disaster, ESA/GEP, EPOS). He will also have to represent SNO in international space projects.

Teams involved within ISTerre: Cycle and Transient Deformation Team, Volcanoes and Geothermal Geophysics Team, Risk and Environment Geophysics Team.

At the national level: SNO ISDeform, ForM@Ter / EPOS (GDM-SAR)

• Sismob / RLBP and Centre de données RESIF: The advent of new seismic acquisition technologies in dense networks (nodes, fiber) has profoundly transformed our ability to image and monitor our subsoil by allowing us to map with unprecedented accuracy geological objects at risk such as volcanoes or faults but also the critical zone (aquifers, glaciers) and regions of interest for geo-resources (e.g. geothermal). The national seismological instrument loan service Sismob, for example, has almost doubled its number of instruments by integrating a network of 100 nodes from industry in 2017. The amount of data acquired has thus increased significantly in recent years, posing new challenges for data integration and distribution by RESIF. In addition, the development of fiber optic/DAS technology currently maturing will further transform the field of experimental seismology with the generation of data volumes that exceed all current capabilities of our services in terms of HR and hardware. The EMSO research infrastructure is already collecting fiber data in the Ligurian Sea, while the MARMOR project integrates a fiber device in Mayotte. Finally, the RESIF data center continues to increase the diversity and complexity of integrated and distributed data. These evolutions are accompanied by profound changes in the national and international vision of data distribution, with systematic FAIRization of data and a high level of requirement for data and service quality. All these activities imply an increasing European and international interaction and cooperation. It is therefore urgent to recruit an assistant physicist to lead part of these activities within the RESIF data center to face these new challenges. In particular, it is necessary to better control the quality of the data and to adapt the procedures to integrate large volumes of data in an efficient way. While major efforts are expected for RESIF-SISMOB and fiber data from permanent and temporary instruments, the work of the recruited person will benefit from the distribution of data from all French seismological networks, including RLBP, GEOSCOPE and RAP. Regarding the DAS/fiber optics, the candidate will also have strong interactions with the Geoazur and IPGP teams that operate (will operate) the fiber equipment for which efficient means of data distribution through RESIF-SI and the RESIF data center must be found.
