IUGG 2023: From 12-19 July, the international geoscience will be guest in Berlin

In the City Cube of Messe Berlin, host GFZ welcomes ~5,000 participants from over 100 countries to one of the world's largest geoscientific conferences.

On 12 July 2023 the General Assembly of the International Union of Geodesy and Geophysics (IUGG) will open its doors in the City Cube of Messe Berlin - after five years of preparation. More than 4,700 participants from over 100 countries have registered for one of the world's largest geoscientific conferences, which takes place every four years - more than ever before. The GFZ German Research Centre for Geosciences is the scientific host.

The thematic spectrum covers almost all areas of the geosciences - from geodesy, i.e. the ultra-precise measurement of the Earth, e.g. via satellites, to hydrology, glaciology and oceanography, atmospheric sciences and climate research, to seismology and volcanology. 

Journalists are cordially invited to attend the conference.

All lectures will be held in English.

Date: 12-19 July 2023

Location: City Cube of Messe Berlin



Some scientific highlights

Union Symposia

Lecture - in the framework of the Union Symposium "Geoscience and Mathematics for Sustainable Development:

  • Contributions of geosciences to sustainable development (goals)

Magdalena Scheck-Wenderoth (Director Dep. 4 Geosystems at GFZ and Professor at RWTH Aachen)

The other Union symposia are:

  • Artificial Intelligence for Managing Natural Hazards and Disasters
  • New Discoveries in Deep Interior of the Earth and Planets
  • New Advances in Planetary Science and Comparative Planetology


Union Lectures

The Union Lectures are hosted by leading scientists from around the world. They are aimed at the broad geoscientific community.

Their topics range from questions about the concept of "time" in measuring the Earth and new methods for gaining insight into the Earth's interior, to new models for mapping groundwater and the role of science in preserving the ocean habitat, to the contradictory role of particulate matter in health and climate protection in developing countries.

We would particularly like to draw your attention to these two lectures:

  • When Giants Falter: Tipping Points in Greenland and Antarctica

Ricarda Winkelmann (Professor for Climate System Analysis at the University of Potsdam and the Potsdam Institute for Climate Impact Research (PIK))

  • SEIS on Mars: First legacy after 4 years of seismic monitoring of Mars

Philippe Lognonné (Professor of Geophysics at the Université Paris Cité and Planetary Seismologist at the Institut de physique du globe de Paris)


An overview of all Union Lectures can be found here: https://www.iugg2023berlin.org/union-lecturers/


Big Themes

Special sessions will address overarching themes such as Open Science, Open Data, Open Software; Needs and Demands of Young Scientists; Diversity, Equality, Inclusion or Education and Capacity Development (North-South Dialogue).

Award ceremonies with lectures

Gold Medal Lecture

The Gold Medal is IUGG's highest award, presented every four years to recognise earth and space scientists for outstanding contributions to geodesy and geophysics.

This year, the Gold Medal is awarded to French paleoclimatologistValerie Masson-Delmotte"for her leadership in projects to record climate in deep ice cores, to decipher isotope deposition on polar snow, and for her outstanding contributions to raising society's awareness of climate change."

  • Her award lecture is titled:

"From the IPCC AR6 to the IPCC AR7: the physical science basis of climate change empowering transformations".


Early Career Awards & Lectures

During IUGG 2023, 10 early career scientists will be honoured for their outstanding research.

An overview of the award winners can be found here.

An overview of their lectures can be found on page 7 of the programme pdf.


Host GFZ invites you to visit

The GFZ German Research Centre for Geosciences is the scientific host of the "IUGG 2023". The Local Organising Committee is headed by Harald Schuh, Director of the GFZ Department of Geodesy. He said:

"We are delighted that this major gathering of geoscientists from all over the world is taking place in Berlin, and thus in Germany again after many years. In the Berlin-Brandenburg region, one of the largest scientific communities in the world is conducting research on questions relating to the Earth system. In addition to the many scientific highlights, IUGG 2023 will offer a special platform for personal encounters, the exchange of ideas and the development of new concepts for international scientific cooperation, which suffered a setback in the Corona pandemic. And it will help create a new spirit to address pressing major societal challenges such as global environmental change and natural hazards, and to stimulate new geoscience research."


Public days in the exhibition hall: 14-16 July, 10:30am-4:30pm.

As part of the Science Year 2023 "Our Universe", the conference opens its exhibition area to all interested parties

On the public days, all interested parties are invited to visit the exhibition hall to find out about current research topics and innovations in the geosciences and to talk to researchers at information stands.

They are also aimed in particular at young people, who can find out about study prospects, for example.

On these days, admission to the exhibition hall is free of charge.


Special highlights of the exhibition:

  • GFZ with RIFS: Changing presentation of current research topics (see details below)
  • NASA: A large exhibition area
  • Airbus
  • Federal Institute for Geosciences and Natural Resources (BGR)
  • TerraQ research project: development and application of new quantum technologies and measurement methods for gravimetric surveying of the Earth - on the ground and from space.
  • Companies such as Digos, Nanometrics or Kinemetrics, which develop and offer technology for satellite as well as earthquake and tsunami detection.
  • The mobile dome of the Berlin planetariums

IUGG is an international scientific organisation primarily concerned with the disciplines of geodesy and geophysics. It was founded in 1919 and currently has 58 full and 15 associate member states. It comprises eight semi-autonomous associations, each responsible for a specific subject area.

Every four years, the IUGG holds its general assembly, to which the entire geoscientific community is invited to participate in scientific exchange through lectures, panel discussions, workshops and poster presentations.

During the general assembly, IUGG leadership positions are elected and important decisions are made, such as the adoption of internationally recognised resolutions and the venue of the next assembly.
