Institut de Physique du Globe de Paris. It is a French grand établissement of higher education and research dedicated to the study of Earth and planetary sciences. The institute is a component of Université Paris Cité and is jointly operated with the CNRS and the Institut de recherche pour le développement. Its mission encompasses fundamental research, observation of geophysical phenomena, and advanced teaching in geophysics, geology, geochemistry, and planetary science.

History

The institute was founded in 1921 by the eminent geophysicist Charles Maurain, succeeding the former Laboratoire de Sismologie and Bureau Central Météorologique. Its creation was driven by the need for a centralized French institution to study the physical properties of the Earth. Early work focused on seismology, terrestrial magnetism, and atmospheric electricity. Under the leadership of directors like Jean Coulomb, it expanded significantly post-World War II, establishing key observatories. It became a grand établissement in 1985, and in 2007, it relocated to the new Campus des Grands Moulins as a founding member of the then Université Paris Diderot, now Université Paris Cité. Its history is intertwined with major projects like the Deep Sea Drilling Project and the Apollo program.

Research and scientific activities

Research is organized around understanding Earth and planetary systems from their deep interiors to their surfaces. Major themes include seismology and geodynamics, studying earthquake mechanisms, Earth's internal structure, and plate tectonics. The volcanology department conducts research on magma dynamics and eruptions at volcanoes like Piton de la Fournaise and Mount Etna. In geomagnetism and paleomagnetism, scientists investigate the Earth's magnetic field and its reversals. The planetary science team analyzes data from missions like InSight to Mars and BepiColombo to Mercury. Interdisciplinary work in geochemistry and cosmochemistry examines the formation of the Solar System and Earth's core.

Education and training

The institute is deeply integrated into the graduate programs of Université Paris Cité. It is a leading center for the Master of Science in Earth and Planetary Sciences, Environment, attracting students internationally. It supervises numerous PhD candidates within the École doctorale des sciences de la Terre et de l'environnement et physique de l'Univers. Training emphasizes a strong coupling between theoretical coursework, laboratory experimentation, and field observations. The institute also hosts the prestigious Agrégation preparation in Physical Sciences and offers specialized continuing education for professionals through its involvement with the Institut de formation de l'environnement.

Observatories and facilities

The institute operates a global network of geophysical observatories for long-term monitoring. These include the Observatoire Volcanologique du Piton de la Fournaise on Réunion, the Observatoire de Physique du Globe de Clermont-Ferrand, and the Chambon-la-Forêt magnetic observatory. It manages instrumental networks for seismology (RéNaSS), volcanology, and geomagnetism across France and its overseas territories. Key laboratory facilities include the High Pressure Laboratory simulating planetary interiors, the Paleomagnetism Laboratory, the National Mass Spectrometry Facility for isotope geochemistry, and the Cryo-SEM for sample analysis. The IPGP Data Center archives and distributes geophysical data globally.

Notable people and alumni

Many distinguished scientists have been associated with the institute. Founders and early directors include Charles Maurain and Jean Coulomb. Notable researchers include Claude Allègre, a former director and Minister of Education; Vincent Courtillot, known for work on geomagnetic reversals; and Barbara Romanowicz, an expert in global seismology. Alumni and former members have led major organizations like the CNRS, the Institut national des sciences de l'Univers, and the European Research Council. The institute has also hosted renowned visiting scientists such as Harold Jeffreys and Keith Runcorn.
