| The Global Heat Flow Database |

Revision 2020-2025

In 2020, the IHFC initiated a fundamental revision of the Global Heat-Flow Database. The process involves a multi-national collaborating project (learn more about the). Here, you will find the relevant updates on the project status.

Step 8: A new heat flow data portal

A first heat-flow data viewer was added. Further functions and more details will follow. Learn more about the World Heat Flow Database project.

Step 7: Collaborative development of a new quality scheme completed

Schedule: 10/2021 - 06/2023

What can you do? If you want to join the process and if you are willing to put some work into the development of a new quality scheme/workflow, please contact us (heatflow@ihfc-iugg.org). A first initial online meeting was held in October 2021 to organize the on-going work in a series of online workshops. Read the minutes for more information:

  1. Kick-off meeting (Okt/21) minutes
  2. Workshop 1 - Conductivity (Nov/21) minutes - youtube recording
  3. Workshop 2 - Scheme proposal (Feb/22) minutes - youtube recording
  4. Workshop 3 - Conductivity 2 (Mar/22) minutes - youtube recording
  5. Workshop 4 - Temperature (Apr/22) minutes - youtube recording
  6. Workshop 5 - Marine (Jun/22) minutes - youtube recording
  7. Workshop 6 - General discussion (22/Jun/22) - no minutes
  8. Publication (on-going)

Step 6: Reassessment of the global heat flow database in progress

Schedule: 05/2021-2025

Step 5: New database and adding data completed

Schedule: 04/2020 - 03/2021, ff

The IHFC has updated the database accordingly to the new structure (April 2021). The next release is planned for June 2022.

What can you do?

New heat flow data not contained in the IHFC database so far can be reported via heatflow@ihfc-iugg.org or by using the submission form.

Step 4: Update literature database completed

Schedule: 04/2020 - 04/2021

The global heat-flow database contains nearly 1300 (actually much more) different references, which are usually given in short abbreviations and compact descriptions. The content of those entries shall be extended to their full bibliographic reference. This overview should build the basis for the upcoming reassessment of the heat flow data.

Work in progress (Start: 20 April 2020)



What can you do? Nothing else, the work is almost done. :)

Step 3: Collaborative development of the new database structure | completed (04/2021)

Schedule: 05/2020 - 04/2021

The revision of the database structure was a collaborative work open to each scientist experienced with heat flow data. The new structure is the first concrete result of the database revision initiated last year,and replaces the long-serving structure of Jessop et al. (1975). The paper on the new database structure is currently in print for the next issue of IJTHFA (April 2021).

What can you do? If you want to join the process and if you are willing to put some work into the development of a new database structure, please contact us. Questions involved in this process are for example: what data are required to describe heat flow data sufficiently? What kind of meta-data is required for the development of a global heat-flow research data infrastructure? To address these questions efficiently, small thematic working groups will be set up focussing thermal properties (including heat production), temperature and temperature gradients, heat-flow determination, site-specific data, correction procedures, quality criteria, and other meta-data. A first initial online meeting was held in May 2020 to organize the on-going work in small thematic groups. Read the minutes for more information. Minutes for subsequent workshops can be find there as well.

Step 2: A new heat flow data viewer | completed (12/2020) |

The first heat-flow data viewer was added to the IHFC website. More details will follow.

Step 1: Relocation | completed (04/2020) |

In April 2020, the Global Heat Flow Database, that has been maintained by the IHFC custodian, Will Gosnold, for the last 20 years at the server of the University of North Dakota, was moved to the official website of the IHFC.
