CDGP data center, new data for interdisciplinarity research

The Data Center for Deep Geotermal Energy (CDGP-Centre de Données de Géothermie Profonde, https://cdgp.u-strasbg.fr/) was launched in 2016 and managed by Interdisciplinary Thematic Institute for Geosciences for the energy system Transition (ITI GeoT, https://geot.unistra.fr/), with the purpose of archiving, preserving and distributing deep geothermal data in the Alsace region (France) for the scientific community and R&D activities. The CDGP is furthermore an internal node of EPOS TCS Anthropogenic Hazards (https://www.epos-eu.org/tcs/anthropogenic-hazards), the data provided concerning geothermal sites in Alsace are therefore also available on the EPISODES platform (https://episodesplatform.eu/), which enables users to process and analyze the data they download. The CDGP collects high-quality data from different phases of deep geothermal projects, especially from exploration and development phases. The aim of this service is to provide downloadable multi-disciplinary data, ranging from industrial hydraulic information to seismic records and catalogs, through geological logs and fault maps for example. The data are thoroughly filtered, controlled and validated by analysts, and are grouped into “episodes”, referring to a set of relevant geophysical data correlated over time, and establishing links between anthropogenic seismicity and an industrial activity.

As part of the European Geo-INQUIRE project (GA n. 101058518, https://www.geo-inquire.eu/), we are now expanding the types of data that we distribute. The raw data (RINEX) from GNSS stations that are monitoring the surface deformation around geothermal site are now available on the website. In a next step, we will add complementary information and metadata to our provided database (e.g. precise position/velocity/strain) thanks to our collaboration with EPOS TCS GNSS. We are currently in the process of developing strategies with EPOS TCS GIM (Geological Information and Modeling)  to provide geological maps and borehole data for the “episodes” sites. The aim is to use the TCS GIM services currently under development and benefit of the synergy from the various leading projects.

Specific procedures have also been implemented since the beginning of the project to respect international requirements for data management. FAIR recommendations, for example, are followed to distribute data that are Findable, Accessible, Interoperable, and Reusable.
