This session is dedicated to the award division ceremony and medal lecture of the Christiaan Huygens Medal (2026 edition), conferred by the Geosciences Instrumentation and Data Systems (GI) Division of the European Geosciences Union.
The Christiaan Huygens Medal was established by the GI Division to recognise outstanding and sustained contributions to the advancement of geoscientific instrumentation, observational methodologies, and data systems within the scope of the Division. The medal is awarded for a major innovation, development, or discovery that has had a significant and lasting impact on its field, or for a coherent body of work carried out over an extended period that has led to substantial scientific and technological progress.

In this session the Stratigraphy Sedimentology and Paleontology Division (SSP) celebrates the Jean Baptiste Lamarck Medal. This year the SSP Jean Baptiste Lamarck Medal has been awarded to Benjamin Bomfleur for his contribution in the field of paleontology. A lecture by Benjamin Bomfleur will be part of this session.

Marie Tharp Medal Lecture by Christian Teyssier

The Marie Tharp Medal is awarded to scientists in recognition of their outstanding contributions to tectonics and structural geology. It acknowledges exceptional scientific achievements in advancing the understanding of tectonic processes that shape Earth's lithosphere and research that bridges these disciplines across spatial and temporal scales.

The Geodesy Division medal and award ceremony will feature the Geodesy Division Early Career Scientists (ECS) Award presentation given by Eva Börgens and the Vening Meinesz Medal lecture by Frank Flechtner.

This session is dedicated to the award division ceremony and invited lecture of the GI Division Outstanding Early Career Scientist Award (2026 edition), conferred by the Geosciences Instrumentation and Data Systems (GI) Division of the European Geosciences Union.
The GI Division Outstanding Early Career Scientist Award (formerly the GI Division Outstanding Young Scientists Award) recognises outstanding scientific achievements by an Early Career Scientist in the field(s) of geoscientific instrumentation, observational methodologies, and data systems within the scope of the Division. The award is presented to researchers who have made innovative and influential contributions at an early stage of their career, demonstrating scientific excellence, originality, and strong potential for future leadership in the discipline.

As every year, SSP recognizes and rewards the most outstanding ECS in SSP fields. This year the Outstanding ECS Award has been awarded to Matthias Sinnesael. The session will see the lecture by Matthias abut his research work.
