Post-doc : Project NEWTON, New Tools for terrain gravimetry

Secteur d'activité : Recherche

Employeur : The Istituto Nazionale di Geofisica e Vulcanologia

Localisation : The place of work will be the Catania Section of INGV (Osservatorio Etneo) in Italy.

Description :

The Istituto Nazionale di Geofisica e Vulcanologia (www.ct.ingv.it) will soon invite applications for the following position:
- Full time Post-Doctoral Scientist position for 36 months
- Starting date: 1st January 2019
- Annual gross (net) salary: 43.9 k€ (23.4 k€).
The postdoctoral researcher will work within the framework of the H2020 project NEWTON-g (New tools for terrain gravimetry), coordinated by Dr. Daniele Carbone and funded under the FET-Open RIA Programme (H2020-FETOPEN-1-2016-2017).

Tasks:
The postdoctoral researcher will work in close collaboration with the coordinator of NEWTON-g (D. Carbone) and the Volcano Gravimetry team of INGV-OE in Catania. He/she will be involved in the implementation of different activities under NEWTON-g, including, besides the management of the project itself (WP 1):
 the supply of relevant geophysical information to partners tasked with designing and developing the new instruments (WP 2);
 the installation of the new “gravity imager” in the active crater zone of Etna volcano (WP 3);
 the creation and editing of the database developed in the framework of the project (WP 3);
 the analysis and interpretation of the gravity time-series produced by the new measuring system (WP4)

Profil :
 PhD in Geosciences, Engineering Geophysics or a related discipline
 Strong background in analysis and interpretation of geophysical time-series, with focus on gravimetry
 Substantial computing and programming experience
 Excellent oral/written communication skills in English
 Substantial research experience and proven publication record are preferred

Summary of the project
Poor knowledge of the spatio-temporal changes in the characteristics and distribution of subsurface fluids remains an insurmountable barrier to addressing important societal issues, including: sustainable management of energy resources (e.g., hydrocarbons and geothermal energy), management of water resources, and assessment of hazard (e.g., volcanic eruptions). Gravimetry is highly attractive because it can detect changes in subsurface mass, thus providing a window into processes that involve deep fluids. However, high cost and operating features associated with current instrumentation seriously limits the practical field use of gravimetry.
NEWTON-g proposes a radical change of paradigm for gravimetry to overcome such limitations. We aim at developing a field-compatible gravity imager able to real-time monitor the evolution of the subsurface mass changes through continuous images of the gravity field. This system will include an array of low-costs MEMS-based relative gravimeters anchored on an absolute quantum gravimeter. The adjustable position, grid and shape of the array of sensors and the continuous logging of the gravimeters will provide imaging of gravity changes, associated with variations in subsurface fluid properties, with unparalleled spatio-temporal resolution.
Specific work will be carried out to ruggedize the devices for field operation. We will deploy the new gravity imager at Etna volcano (Italy), where frequent gravity fluctuations, easy access to the active structures and the presence of a multiparameter monitoring system (including traditional gravimeters) ensure an excellent natural laboratory for testing the new tools. Insights from the new gravity imager will be used for volcanic hazards analysis, to demonstrate the importance of gravity to problems of societal relevance. A successful implementation of NEWTON-g will open new doors for geophysical exploration and will shift the locus of gravimeter manufacture from North America to Europe.
