Furthermore, the potential use of monitoring the vertical gravity gradient in hydrogeophysical applications was assessed experimentally and using hydrogravimetrical modelling. The measurement of g was found to not be influenced by temperature and tilt changes. We assess the performance of the absolute quantum gravimeter device AQG#B01, developed by Muquans, in view of its precision, stability, repeatability and of future terrain deployment. Quantum gravimeters provide the possibility of continuous, high-frequency absolute gravity monitoring without instrumental drift while remaining user-friendly and transportable. The gravitational attraction of the Earth (referred to as g) is measured with gravimeters. Gravimetry studies the variations of the Earth’s gravity field which can be linked to mass changes studied in various disciplines of the Earth sciences. ![]() Author ENIGMA Posted on Format Status Categories Non classé Congratulation Doctor Anne-Karin Cooke !ĮNIGMA fellow Anne-Karin Cooke successfully defended her thesis “Characterisation of a new mobile absolute quantum gravimeter: Application in groundwater storage monitoring” on Friday 30th October 2020 virtually from Montpellier University. The network ENIGMA gathers 21 partners (15 academic and 6 industrial) from 8 European countries.Įach of the 15 PhD students conducts the research work in 2 or 3 institutions, in collaboration with the industrial partners. The 15 young PhD students trained within the network contribute to develop the spatial representation of subsurface heterogeneity, fluxes, chemical reactions and microbial activity, through the integration of data and approaches from geophysics, hydrology, soil physics, and biochemistry.
