The AGU (American Geophysical Union) awards two IPGP researchers among the hundred or so international prize-winners in its various sections for 2022! Philippe Logonnée, professor at Université Paris Cité and geophysicist at the IPGP has been awarded the Beno Gutenberg Lecture and Paul Rebischung, IGN research officer at the IPGP has been awarded the Ivan I. Mueller Award.
The Beno Gutemberg Lecture is awarded annually by the Seismology Section of the American Geophysical Association for outstanding contributions to seismology.
Philippe Lognonné, Professor at the Université Paris Cité and geophysicist at the Institut de Physique du Globe de Paris, has been one of the main architects of the development of planetary and ionospheric seismology for almost 30 years. He is scientific manager of the SEIS seismometer, which will be installed on Mars at the end of December 2018, and which has enabled the first seismic models of the internal structure of Mars to be drawn up, from the core to the subsurface. This project crowns 30 years of effort, which began in 1989 with the OPTIMISM seismometer, which was lost shortly after the launch of the Mars96 probe.
He is the scientific leader of the long-period component of the FarSide Seismic Suite, which will explore the far side of the Moon seismically in early 2025. Finally, he participated in the re-analysis of the Apollo seismic data, and since the end of the 1990s has been developing ionospheric seismology, which makes it possible to detect and model seismic waves and tsunamis on Earth. This technique could perhaps be used in the future to explore Venus seismically.
The Ivan I. Mueller Award is presented annually by the Geodesy Section of the AGU to one or more scientists in recognition of their significant contributions to the geodesy community.
Paul Rebischung is currently an IGN research fellow at the Institut de physique du globe in Paris, in the geodesy team. Since 2010, he has been an active member of the International GNSS Service (IGS), a voluntary federation of more than 200 organisations guaranteeing free access to high-quality GNSS data and products. Since 2017, he has held the role of “Reference Frame Coordinator”. In this role, he is responsible for calculating precise daily positions for the 500 or so stations in the IGS network, as well as for the IGS’s contribution to the successive realisations of the International Terrestrial Reference Frame (ITRF).
He has carried out various studies on the errors affecting the positions of GNSS stations, thereby helping to improve the accuracy of IGS products. He has also contributed to several studies using IGS products to observe geophysical phenomena such as the current rise in sea levels and large-scale water mass transfers.
