The iOSG superconducting gravimeter from the Strasbourg Gravimetric Observatory

2016-03-29

Description : The Résif superconducting gravimeter, hosted by the Eost in Strasbourg, provides the French contribution to the continuous measurement of temporal variations in the Earth's gravity field. These measurements allow the study of geophysical phenomena within a spectral window ranging from Earth's own modes to long-period variations such as pole motion and tides. This gravimeter belongs to the French seismological and geodetic network Résif, a national research infrastructure dedicated to the observation and understanding of the structure and dynamics of the Internal Earth. Résif is based on high-tech observation networks, composed of seismological, geodetic and gravimetric instruments deployed in a dense manner throughout France. These data make it possible to study with high spatial and temporal resolution the deformation of the ground, surface and deep structures, seismicity on a local and global scale and natural hazards, and more particularly seismic hazards, on French territory. Résif is integrated into European (EPOS - European Plate Observing System) and global systems of instruments for imaging the Earth's interior as a whole and studying many natural phenomena. This gravimeter also integrates a global network of superconducting gravimeters as part of the Global Geodynamics Project, which includes more than 30 stations operating worldwide and has been a service of the International Geodetic Association (IAG) and GGOS (Global Geodetic Observing System) since 2015 called IGETS (International Geodynamics and Earth Tides Service). The objectives pursued concern global geodynamics and fluid nucleus dynamics, solid Earth-atmosphere-ocean-hydrology interactions and the calibration of satellite data for water resources estimation.
