Prof. Jacques Hinderer from University of Strasbourg, France Visited IGG TEXT SIZE:A A A

Invited by State Key Laboratory of Geodesy and Earth’s Dynamics (SKLGED), prof. Jacques Hinderer from University of Strasbourg, France visited Institute of Geodesy and Geophysics(IGG) during the period from Sept 7th to 14th. During the one-week visit, the SKLGED arranged four academic exchanges. Many researchers and graduate students participated in the exchanges, including students from the IGG, Wuhan University, Huazhong University of Science and Technology and China Earthquake Administration. Academic activities were hosted by researcher Sun Heping from IGG.

Prof. Hinderer gave an academic report titled ‘Time variations in Earth’s gravity and inferences on underground and sub-surface mass changes’ . His research focus on Hybrid gravimetry, which combines different types of instruments such as spring Relative Gravimeter (RG) and Superconducting Gravimeter (SG), Absolute Gravimeter(AG) and space satellite gravity technology to perform gravity measurement and others related scientific research. Through the French research team's research projects in various regions of Africa and Europe, it is demonstrated that hybrid gravity measurements can provide a richer understanding of the temporal and spatial gravitational field changes in the study area. Prof. Hinderer’s report showed us the temporal variation of the Earth's gravitational field in monitoring the mass redistribution (water, oil, gas, ice, magma) near the Earth's surface, and its various fields application prospects, such as volcanology, hydrology, glaciology, geothermal etc.

During the exchange, the geophysical and internal dynamics group of IGG organized a two-day academic report. There were nearly 10 researchers introduced the data processing methods and research progress related to surface and spatial gravity measurement in China, and introduced the research results in many aspects such as seismic position, deformation theory, internal dynamics of the earth, the gravity field measures background noise,Solid tide and tidal load in Antarctic region. Hinderer expressed his admiration and great interest for the achievements made in scientific research and instrument development, and had a heated discussion with others and put forward many useful suggestions. Hinderer also visited the laboratory of geodesy and geophysical observation technology at the wuhan institute of geodesy in wuhan, China.

The institute of geophysics of the university of Strasbourg is an important research center of geoscience in France and enjoys a high reputation internationally. During the international exchange, sun heping and Hinderer discussed future cooperation issues involving the measurement of the earth's gravity field and the application of scientific issues.
