International heat flow conference and workshop in Potsdam

Hosted by the GFZ German Research Centre for Geosciences, the “7th International Meeting on Heat Flow and the Thermal Structure of the Lithosphere” (the Cermak7 Meeting) was held in Potsdam from 20th to 22th June. Two years after a first attempt to host the conference was canceled due to the beginning of the corona pandemic, the meeting now provided a unique opportunity for researchers, students, and industry experts from across the world to meet in person and discuss recent results and developments in heat-flow determination and interpretation, experimental petrophysics, geothermal exploration, and lithosphere studies. For understanding thermal transport processes in these research fields, heat flow is an essential parameter. More than 60 researchers from 19 countries attended the meeting, which is the largest specialist conference on heat-flow techniques, data and its interpretation. After the two-day conference, a one-day workshop for the revision of the global heat-flow database was held. A major achievement of the workshop was the finalization of a quality scheme for the tens of thousands of data incorporated in the global heat-flow database. The in-person workshop relied on a series of collaborative online workshops that started in November 2021.

Workshop invitation - IHFC Global Heat Flow Database

After redefining the database structure and starting the assessment process itself, a new globally applicable quality scheme represents the third major step of the revision process of the global heat-flow database. We think that this step represents a large challenge but is also mandatory being able to provide an authenticated global heat flow database.
Therefore, we are happy to announce a zoom kick-off meeting “Defining a quality evaluation scheme/process for the global heat-flow database” to take place at the 25th, 27th or 28th of October. The objectives of this meeting are to discuss and to agree on the working procedure for the development of the new quality scheme for the global heat flow database. As in the structure workshop last year, we suggest again to establishing small topic-related working groups in this kick-off meeting to develop recommendations during the next 6 months. Possible subtopics could be method qualification, uncertainty quantification, and external effects.
We kindly invite you to join this process and to bring all your expertise into this project! Please register for the kick-off meeting until 15th October 2021 in time. Based on your registration we will adjust and announce the most appropriate time of the meeting. An agenda will be provided beforehand.

Invitation: Kick-off meeting “Defining a quality evaluation scheme/process for the global heat-flow database” Type: 75 min. zoom meeting at 1 pm UTC Registration: doodle a date.

New definition of the Global Heat flow Database online

In May 2020, a series of online workshops was initiated by the IHFC to discuss the recent demands on the structure of the Global Heat Flow Database. Now, as a first results of this truly international collaborative work, a new paper was published containing a new data description that substitutes the long-established definition from Jessop et al. (1976).
Find the new publication here. Read also the comment of Alan Jessop on this approach in his preface to the 2021 ijthfa volume. Please, consider the new structure for any data upload of new heat-flow data to the GHFDB.

Obituary Alan Edward Beck

In memoriam Dr. Alan Edward Beck (1928-2020)


Alan Beck (to the right) in 1995? in Rio de Janeiro; together with Seiya Uyeda, Valiya Hamza, and Vladimír Čermák (from left to right); picture credits: unknown

"All my colleagues Jan Safanda, Milan Kresl, Petr Dedecek as well as myself are deeply grieved to learn of the death of Professor Alan E. Beck. We all want to express our deepest sympathy to the family and to many of his colleagues, former students and friends.
It is more than 50 years since I first met Alan when I came to Canada to spend my two years as the PDF in that time Dominion Observatory in Ottawa. Alan served as the Professor in Geophysics at the University of Western Ontario, London, and we had good chances to meet each other. We quickly established a really firm friendly relation and I benefited very much from his practical advices how to organize laboratory work.
Earth Sciences the early sixties presented an incredible progress in geothermics. In 1963 the International Heat Flow Committee (today known as Commission, IHFC) was established at the 13th IUGG General Assembly in Berkeley. Only two years later a comprehensive volume “Terrestrial Heat Flow” (edited by WHK Lee) appeared summarizing the results and basic principles of heat flow investigations. With no exaggeration this book can be still considered as certain “Heat Flow Bible”. Alan Beck contributed by one of its chapter “ Techniques of measuring heat flow on land”. Here he introduced his “Divide-Bar apparatus”, which become a useful tool for laboratory thermal conductivity measurements. I am sure that even today some laboratories are still using this instrument as an alternative method. In this sense Alan was a real pioneer of the thermal conductivity measurements.
Alan E. Beck was the 4th Chairman of the IHFC (1979-1983) and I had pleasure to work with him as the IHFC vice-secretary. Memorably days. One of the Alan´s merit was the fact that he proposed and elaborated the IHFC Bylaws, which with only some slight changes or additions are fully applicable today. During 50 years of our friendship and scientific cooperation we were meeting frequently attending and co-organizing various international conferences and symposia all over the world. Alan participated in the preparation of the 1987 Vancouver 19th IUGG General Assembly and was the Chairman of the Local Organizing Committee of the 1981 London 17th IASPEI Assembly. Alan also visited my country attended some of our six famous “Heat Flow Castle meetings” which I organized in Czechoslovakia/Check Republic between 1982 and 2006. I am extremely sorry that Alan due to his health problems could not attend the last 2019 IUGG General Assembly in Montreal. I was looking very much to meet him there.
Professor Alan E. Beck will be long remembered by us in the Geophysical Institute in Prague as well as by all IHFC members as one who devoted his life career to geophysics and to the service of the International Heat Flow Commission of the IASPEI. I shall always regard it as a great honor and privilege to have known him personally."

The IHFC sponsors the symposium entitled "Towards 60 years of activity of the International Heat Flow Commission" as Symposium S24. It has been designed to highlight the accomplishments of heat-flow studies and their role in understanding a wide range of Earth processes. The contributions to the symposium will include critical reviews identifying key-knowledge gaps as well as recent work in all aspects of geothermal investigations. It provides also a good opportunity to promote the contributions of IHFC to IASPEI themes.

The IHFC asks you to consider submitting multiple abstracts to this Symposia and encourage colleagues in related fields to support the Symposia S24. The relevant information are given below.

Conveners: Sukanta Roy (India), Robert N. Harris (USA), Sven Fuchs (Germany), Massimo Verdoya (Italy)

Abstract submission deadline: April 15, 2021

Heat flow Questionnaire

Beginning with the new term of the International Heat Flow Commission last summer, the IHFC decided at the IUGG in Montreal (minutes) to reorganize and relaunch the International Heat Flow Database. An essential part of it will be the restructuring and revision of the database and the development of a new heat-flow research data information system. Truly, this is ambiguous.

We think it is best to develop the functionality of the IHFC heat-flow data portal along the scientific needs of our community.

Please, share your past experience with the database and inform us on your requirements on a heat-flow data portal. Please let us know in particular about features, functionality and/or services that would be helpful for your work. With spending 5 minutes of your time, you can help us to get an overview of the demands and expectations.

Don’t miss the opportunity to be part in this process.

Please give us your feedback in the online questionnaire (surveymonkey).

We will summarize the results here at the IHFC website and during the Cermak7 meeting, where the collaborative revision of the available data will be initiated in a special workshop (http://cermak7.ihfc-iugg.org). If you wish to share your ideas prior to this event you are very welcome to give us a notice on that.
