The heat flow summer 2023

The IUGG General Assembly 2023 will take place in Berlin (Germany) from 11–20th of July. We have planned a number of activities during or attached to the IUGG that are related to heat flow education and science. Amongst these activities are:

  • July 03–07: 5-day summer school on heat flow determination and interpretation (Mon-Fri, at GFZ Potsdam)
  • July 08–09: 2 day workshop on heat flow in Antarctica (Sat-Sun, at GFZ Potsdam)
  • July 10–11: 2 day workshop on heat flow in Africa, South- and Central America (Mon-Tue, at GFZ Potsdam)
  • July 11–20: IUGG General Assembly 2023 (in Berlin)
  • July X–Y: IHFC 60th anniversary Heat flow symposium (at IUGG in Berlin)
  • July X–Y: IHFC business meeting (at IUGG in Berlin)

Content and Objectives: The heat flow summer school is aiming to provide comprehensive training on heat-flow determination and evaluation with particular reference to early-career scientists, young researchers, and encouraged students with pretensions to focus on this topic in their future career. The basic idea is to give opportunities to be trained on techniques of heat-flow determination and to extend the network of researchers interested in heat flow and related research topics. The participants will be involved in discussions and working groups and they will learn tools to resolve challenges in their daily work on heat-flow research. The summer school will comprise lectures, short talks, different discussion formats, and interactive group activities. We also intend to stimulate the participants to engage with institutions and the public in their home countries to improve science awareness on heat flow, help to develop informed opinions, and enhance the transferable skills of scientists.

  • If you have further questions regarding the summer school or the application procedure, please contact us:

How we decide ???

Candidates to the heatflow.summerschool are selected by two criteria:

  1. their motivation expressed
  2. the overall distribution of the countries of origin
  3. diversity and gender equality

Once the application is received, it is carefully examined by our staff. They check whether it fulfills the formal requirements and evaluate it according to the criteria listed above. The deadline for applications is March 15. We will inform the applicants latest April 01.


Which nationalities are supported?
We support researchers from across the world. Currently, there are limitations to colleagues with affiliations from Russia and Belorussia. Please contact us if you are unsure whether you are eligible to apply.

Antarctica Workshop

Content and Objectives: The Antarctic workshop, following the summer school event, covers geothermal heat flow (GHF) affecting the ice sheet temperature, determining how it slides and internally deforms, as well as the rheological behavior of the lithosphere. GHF remains poorly constrained and there are large discrepancies in currently available glaciological and geophysical estimates. The workshop details on current methods and discusses their challenges and limitations and recommends key future directions in GHF research.

What to expect

  • two-day Antarctica heat flow workshop
  • establish ties with other heat-flow researchers and strengthen the network of young researchers working on this fascinating topic

Contact Information: Florian Neumann ( Location: GFZ German Research Centre for Geosciences, Telegrafenberg, Potsdam. Building: A69 (Geoenergy) Room: Z01 Days: From July 08th – July 09th Organizer: Tobias Stål (University of Tasmania)

Workshop lead

Tobias Stål received a PhD in Geophysics in 2021 and is presently a postdoc research fellow at the Australian Centre for Excellence in Antarctic Studies (ACEAS) at the University of Tasmania. He is research is related on problems to ice/sold Earth interactions in Antarctica, including subglacial geothermal heat and explores computational and statistical methods to study Antarctica’s deep and shallow structure and properties. Furthermore he works on an Antarctic rock sample database (PetroChron), assuring quality control and updating the database structure and workflow. Tobias is co-chairing the SCAR INSTANT subcommittee for Antarctic geothermal heat and is leading the ACEAS workgroup for remote instrumentation. He has experience in coordinating and conducting remote fieldwork in the high Arctic and Antarctica, including seismic and GNSS deployment and geological mapping.

Heat Flow Workshop on Africa, South Atlantic and South- and Central America:

Content and Objectives:
The heat-flow workshop will play a fundamental role in completing the summer school training program. The activities will be focused on the Global Heat Flow Data Assessment Project, which the IHFC started in 2021 and strategies for collaboration and developing projects to fill data gaps, in particular in Africa, and South- and Central America. The reasons for such target regions are: 1) the coverage and the overall quality of heat flow data is poor and 2) there are only a few heat-flow researchers active in these regions.

What to expect

  • two-day ACSA workshop on strategies and promotion in heat flow activities and discussion on the current heat flow assessment project.
  • By participating the ACSA workshop you will jointly elaborate a white paper on the heat-flow developments for target regions
