The digitization of geoscientific data (mainly from the literature) is a huge effort that enables the integration of previously fragmented datasets, making it easier to link and analyze information from diverse sources. As a result, the volume of digital data collected during research continuously increases, as does the complexity of managing and connecting these datasets.

A significant portion of this data comes from expensive and resource-intensive research efforts, including (i) ship-based exploration campaigns, (ii) International drilling programs (e.g., IODP, ICDP), (iii) public geological surveys, and (iv) exploration projects from the industry.

These datasets are unique and irreplaceable, and play a fundamental role in geoscientific research. The IHFC and heatflow.world are committed to making these valuable datasets publicly accessible. This includes historical data dating back to the early 20^th century, featuring (i) borehole petrophysical and geophysical data, (ii) oceanographic data from seafloor probing expeditions, (iii) extensive metadata for environmental corrections.

All services and products provided by the Global Heat Flow Data Research Infrastructure are based on curated datasets collected, cleaned, and maintained by the IHFC and a global network of researchers. Data is sourced from:

• Scientific literature
• Direct submissions by researchers and institutions
• Data commissioned or provided to IHFC for integration into the Global Heat Flow Database (GHFDB)

Every dataset undergoes a rigorous quality-control process led by IHFC experts and voluntary contributors, ensuring accuracy, consistency, and usability. The quality scheme of the Global Heat Flow Database is described in detail in Fuchs et al. (2023) https://doi.org/10.1016/j.tecto.2023.229976
