Home / Awards & medals / Fridtjof Nansen Medal / 2000 / Stephen A Thorpe
After several years of research on various aspects of the dynamics and energetics of stratified flows, at the Institute of Ocean Sciences, Wormley, Thorpe was appointed to a chair in oceanography at the University of Southampton. His work is widely referred to in the literature in physical oceanography and related disciplines, and has inspired both contemporaries and the following generation of scientists.
Home / Awards & medals / Petrus Peregrinus Medal / 2025 / Nils Olsen
In doing so, his efforts have revolutionised our measurements of Earth’s field as well as our interpretations of magnetic induction processes occurring above Earth, in our oceans, in the lithosphere, mantle and core.
Home / Awards & medals / Vilhelm Bjerknes Medal / 2017 / John M. C. Plane
He is recognised as world-wide expert on high atmosphere chemistry of meteors and metals and made several discoveries in metals in the mesosphere. Plane recently explained the anomalous behavior of potassium, a 50-years unresolved problem. He also made some unique measurements of NO3, BrO, IO, OIO in the marine boundary layer, and made several discoveries in halogen radicals in the atmosphere.
Home / Awards & medals / Petrus Peregrinus Medal / 2008 / Neil D. Opdyke
Having obtained a global perspective, he returned to the US in the mid-1960’s where he began his work on the documentation of magnetic reversals in deep-sea sediments. He found a sequence of polarity intervals similar to that deduced from the age distribution of polarity in disparate lavas, and thereby completely dispelled the notion of self-reversal in rocks.
Home / Awards & medals / Sergey Soloviev Medal / 2019 / Kyoji Sassa
Kyoji Sassa The 2019 Sergey Soloviev Medal is awarded to Kyoji Sassa for outstanding scientific contributions in fundamental research in landslide hazards and in landslide risk-reduction initiatives for the benefit of societies. Kyoji Sassa is one of the most well-known and outstanding pioneering researchers in the field of landslides, and the founding president of the International Consortium on Landslides (ICL) established in 2002.
Home / Awards & medals / Hans Oeschger Medal / 2017 / Denis-Didier Rousseau
Denis-Didier Rousseau has therefore demonstrated leadership by combining different activities in palaeoclimate science, much in the spirit of the late Hans Oeschger. Rousseau is also an excellent facilitator of science and a mentor of scientists. His service to the scientific community is numerous and widespread. He is the founding co-editor of Climate of the Past, a leading EGU journal in this field.
Home / Awards & medals / Division Outstanding Early Career Scientist Awards / 2026 / Eva Pfannerstill
Her postdoctoral research in the United States resulted in the development of novel aircraft-borne flux measurement methods, culminating in a landmark study that demonstrated the temperature-sensitivity of biogenic emissions as a key driver of regional ozone formation.
Home / Awards & medals / Vening Meinesz Medal / 2004 / John Wahr
John Wahr The 2004 Vening Meinesz Medal is awarded to John Wahr for his outstanding and far-ranging contributions in the field of global geodesy. John Wahr defended his PhD thesis in geophysics at the University of Colorado, Boulder, USA, in 1979. He received the prestigious James B. Macelwane Award of the American Geophysical Union in 1985.
Home / Awards & medals / Lewis Fry Richardson Medal / 2011 / Catherine Nicolis
Aside from many other seminal papers, Katy also played an important organizational role in the Nonlinear Geosciences community. She was one of the first chairs of EGSs Nonlinear Processes (NP) section and the key organizer of a remarkably interdisciplinary, week-long meeting in Crete, in the summer of 1985. The resulting proceedings, “Irreversible Phenomena and Dynamical Systems Analysis in the Geosciences,” edited by C.
Home / Awards & medals / Arne Richter Awards for Outstanding Early Career Scientists / 2017 / Yadong Sun
In his still young career, Sun has gained broad insight into most exciting aspects of Earth systems history and of mass-extinction events and received several awards for early career scientists in China. He is author and co-author of an already impressive number of publications published in international top-ranking journals including Earth and Planetary Science Letters, Lithos and Science.
