Vening Meinesz Medal of EGU has been awarded to Prof. Jürgen Müller

The European Geosciences Union (EGU) has been awarding the VeningMeinesz Medal for outstanding research achievements in the field of geodesysince 1998.

In 2023, the award goes to Prof. Jürgen Müller from the Institute ofGeodesy, Leibniz University of Hannover, Germany. The medal is namedafter the Dutch geophysicist and geodesist Felix Andries Vening-Meinesz.With this award, the EGU honours Jürgen Müller's scientific leadership in thefield of Lunar Laser Ranging and the test of general relativity as well as hiscontributions to advancing the field of geodesy especially in the use ofquantum technology for novel applications and measurement concepts. With the latter, also the activities of theIAG Project “Novel Sensors and Quantum Technology for Geodesy (QuGe)” have been acknowledged.

Professor Harald Schuh from the German Research Centrefor Geosciences (GFZ) in Potsdam and former IAG presidentputs it this way in his laudation: “Jürgen Müller inimitablybridges the gap between physics and geodesy, where ground-breaking developments are transferred into geodeticapplications. In his current research, he is working on usingrecent advances in quantum technology and optical clocks toimprove measurements of the Earth’s gravity field and itschanges in space and time. A project that has the potential torevolutionise our understanding of the Earth’s time variablegravity field.”

Report on the 5th Joint International Symposium on Deformation Monitoring (JISDM)

20-22 May 2022, Valencia, Spain

Under the endorsem*nt of the FIG, IAG and ISPRS, the JISDM symposia series is a leading forum in the field of deformation monitoring for more than 40 years. The symposium aims to promote the advancement in deformation monitoring by bringing together traditional aspects of advanced surveying such as optimal measurement techniques and rigorous network analysis with increasingly important features such as 3D visualization, artificial intelligence and new sensors development.

The 5th Joint International Symposium on Deformation Monitoring (JISDM) was held on June 20th – 22th in Valencia, Spain. The Higher Technical School of Geodetic, Cartographic and Surveying Engineering along with the Department of Cartographic Engineering, Geodesy and Photogrammetry at the Universitat Politècnica de València were the host institutions of this event.

The number of participants registered was 195 from 25 different countries. As customary, two types of contributions were allowed, peer review and non-peer review, so that experts with different profiles could equally contribute to the advancement of deformation monitoring. This edition included 90 oral presentations and 18 posters with topics related to technical, methodological, and practical advances in the field of deformation monitoring tackling landslides, debris flows and rockfalls, large engineering structures, metrology and tangible cultural heritage in archaeology and architecture. Two awards were offered for the best oral and poster presentations. In addition, 24 contributions were selected for further publication in special issues of two journals, Journal of Applied Geodesy and Applied Geomatics.

Relevant keynote presentations were given by Dominique Missiaen (Conseil Européen pour la Recherche Nucléaire - CERN), Res. Prof. José Fernández (Institute of Geosciences IGEO- CSIC/UCM, Spain), Prof. Alessandro Capra (University of Modena and Reggio Emilia -UNIMORE) and Prof. Werner Lienhart (Graz University of Technology -TU Graz). They illustrated the key points of deformation monitoring from different perspectives like high-precision surveying, geohazards or geomatics applied to environmental and cultural heritage. They also shared their vision on the evolution of technologies and methods in the planning, analysis and visualization of deformation monitoring for both natural phenomena and man-made structures.

Lastly, the proceedings of the 5 th Joint International Symposium on Deformation Monitoring are being considered to be indexed in the Web of Science. The quality of the scientific contributions deserves indexation. The number of consolidated research groups, the variety of topics and the quality of the contributions allow us to dream of a successful promising future in the deformation monitoring field.

Looking forward to seeing you all with new developments and ideas ready to be shared and discussed in the next 6th JISDM.

Obituary

Ivan Mueller (1930-2023)

Ivan I. Mueller, born January 9, 1930, in Budapest, Hungary, peacefully died on April 12, 2023, in his home in Bloomfield, Connecticut, USA.

In 2020, shortly after his 90th birthday, a congratulatory address was sent to Ivan on the occasion of his 90th birthday. It is extremely sad that so soon after this joyful event his obituary has to be written. OSU (Ohio State University), IAG (International Association of Geodesy), and IGS (International GNSS Service) were the key words in Ivan Mueller’s scientific career.

Having left Hungary after the Hungarian Revolution in 1956, he launched his academic career with a Ph.D. thesis advised by Weikko Heiskanen at OSU. In 1960 he became a faculty member and soon thereafter a very influential professor at the Department of Geodetic Science and Surveying of OSU. The department became his scientific home. Many well-known scientists started their careers in the slave quarters, the working room of Ivan’s students at OSU. According to the OSU chronicle Ivan Mueller was the principal advisor of 25 Ph.D. candidates and many Masters students.

Ivan Mueller is the founder of the Center for Mapping at the Ohio State University and of the NASA Center for the Commercial Development of Space on Real-Time Satellite Mapping. Both centers were established in 1986. The Department of Geodetic Science and Surveying was a worldwide recognized Center of Excellence.

The IAG became Ivan Mueller’s home on the global scale. He shaped the transition from classical to space geodesy, to satellite geodesy in particular. He was the founding president of CSTG, the Commission on International Coordination of Space Techniques for Geodesy and Geodynamics, from 1979 to 1981. CSTG was co-sponsored by IAG and COSPAR, the COmmittee of SPAce Research. The example illustrates Ivan’s talent to create acronyms. CSTG played the leading role for the international coordination of space research during the cold war and for a long time period afterwards. The MERIT (Monitoring of Earth Rotation and Inter-comparison of Techniques for observation and analysis) campaign was initiated by COSPAR in 1980 and it was chaired by Ivan Mueller. MERIT resulted in the creation of the IERS, the International Earth Rotation Service, in 1988. With such high-level activities it was only logical that Ivan Mueller became the IAG President from 1987 to 1991.

Ivan Mueller is the author of more than 200 scientific articles and of five books, which shaped generations of geodesists and geophysicists. His book Introduction to Satellite Geodesy was published in 1964, when this field was new and still dominated by astrometric observations allowing it, however, to establish for the first time a global geodetic reference frame. It was one of the first, if not the first text book about this topic. The book Earth Rotation, theory and observation, published in 1988, is authored by Helmut Moritz and Ivan Mueller, the two giants of geodesy in the 20th century. The book illustrates two guiding elements in Ivan’s life: (1) he was always keen on establishing and maintaining close contacts with other leading scientists in the field and (2) he was deeply interested in the combination of theory and application. It is worthwhile to read the preface and the introductory chapter documenting that theory and observation or theory and Earth rotation monitoring based on international cooperation using state of the art observations, as the book also might have been called, were both equally important to the authors. Remember that the MERIT campaign was underway when the book was written, and that the IERS was not yet established. The book thus marks the transition from classical to modern Earth rotation monitoring.

Towards the end of the 1980s Ivan used his influence as IAG president to establish and chair the IAG Planning Committee for the IGS. In Ivan Mueller’s words “the primary motivation in planning the IGS was the recognition that the most demanding users of the GPS satellites, the geophysical community, were purchasing receivers in large numbers and using them as more or less black boxes, using software packages which they did not completely understand, mainly for relative positioning”. The boldness of his argumentation was breath-taking. Who else would have dared to launch a high-level scientific service using such words? Both, the IERS and the IGS, owe their creation to Ivan Mueller’s leadership and foresight.

Ivan Mueller’s merits were widely recognized and very much appreciated by the science community. He was, e.g., the recipient of the Vening Meinesz Medal of the European Geophysical Society (EGS) in the year 2000 and of the Waldo E. Smith Medal of the American Geophysical Union (AGU) in 2003. Also, the AGU issues on an annual basis the Ivan I. Mueller Award for Distinguished Service and Leadership. He has been honored with the Senior Scientist Award of the Alexander von Humboldt Foundation, became an Honorary Member of the Hungarian Academy of Sciences, and received an honorary Doctorate from the Technical University of Budapest.

Ivan had a lifelong passion for opera, for orchestral, and chamber music. On the occasion of many professional travels he developed the habit to attend classical concerts at the conference locations, sometimes he even by sacrificing conference dinners for the purpose.

The undersigned is extremely grateful to Ivan for his guidance when creating the IGS in the 1990s. His e-mails with the ingress “are you still ticking?” often were wake-up calls to trigger urgent activities.

The entire IAG community pays respect to Ivan I. Mueller for his incredibly valuable contributions to IAG, to geodesy, and to science in general. He will always be remembered.
