Data Sharing & Access
EPOS-NL facilitates global discovery of and open access to solid Earth science data from the Netherlands, with a focus on seismological and laboratory (experimental rock physics, crust/mantle analogue modelling, rock microstructures) data.
Types of data
Different types of laboratory data are collected at different EPOS-NL facilities:
Rock physics data
2D & 3D imaging data
TUD & UU
Analogue modelling data
Data can currently be accessed in the 4TU.ResearchData and Yoda data repositories. In the near future, metadata from open EPOS-NL laboratory datasets will be collectively searchable in the EPOS Multi-Scale Laboratories data catalog.
EPOS-NL laboratory data is published in the institutional repositories of TU Delft (4TU.Researchdata) and Utrecht University (Yoda), then the metadata describing the data will be automatically included in the Multi-Scale Laboratories data catalog for collective discoverability from a single access point.
To share data collected at an EPOS-NL laboratory facility, please follow the instructions for publishing data at the appropriate institution:
- Publishing EPOS-NL laboratory data with Yoda (UU)
- Publishing EPOS-NL laboratory data with 4TU.Researchdata (TU Delft)
Types of data
Seismological data collected as part of EPOS-NL includes raw waveform data (miniSEED) together with station and instrumentation metadata (StationXML).
SEED specification: https://www.fdsn.org/pdf/SEEDManual_V2.4.pdf
StationXML specification: https://www.fdsn.org/xml/station/
Waveform data and station metadata can be accessed through the European Integrated Data Archive (EIDA)’s graphical web interface or web services.
ORFEUS data center, where EPOS-NL seismological data is archived, also provides additional services for waveform data such as data quality tools and visualizations of real time waveforms.

To share seismological data collected using the EPOS-NL infrastructure, please contact Reinoud Sleeman (reinoud.sleeman at knmi.nl) for further information.
Groningen gas field data
The Groningen gas field in the Netherlands is known for its induced subsidence and seismicity caused by gas production. To facilitate ongoing research into these effects (e.g. by the DeepNL program), EPOS-NL disseminates the following key data and model pertaining to the Groningen field:
ORFEUS Data Center (KNMI)
ORFEUS Data Center (KNMI)
Groningen geological model (Petrel)
Distributed Strain Sensing (DSS) data Zeerijp well 2015-2021
Reservoir core photographs
Seismological data flexible network and downhole geophones
KNMI data platform
Mmax II workshop data
Microstructural data Stedum-1 and Zeerijp-3a
Subsurface of the Netherlands data
The Netherlands has an excellent subsurface database, built and maintained by the TNO Netherlands Geological Survey, available via a number of public information portals, such as NLOG, DINOLOKET, THERMOGIS, among others. Complementary datasets included there, or developed elsewhere are provided below.
Subsurface pressure and temperature database Netherlands
EBN and TNO
EBN Data Centre
Integrated catalogue of geological data of the Netherlands (Petrel)
Shallow compaction data Groningen gas field and other locations in the Netherlands

In 2021, 60 TB of data from the recently expanded seismological network in the Groningen field will be added to the ORFEUS Data Center. These data are provided by NAM and will complement the existing datasets at ORFEUS Data Center.
EPOS-NL works with the data centers of its partner institutions to make geologic data openly available, as well as FAIR (Findable, Accessible, Interoperable, and Reusable).
YourData (Yoda) Geoscience is a repository for data from all geoscience disciplines, with a focus on experimental rock physics, analogue modelling, geochemistry, paleomagnetism, microstructural and geological data. Yoda Geoscience is part of the larger Yoda data center, built and maintained by Utrecht University. Openly published data are currently being made findable in different international data catalogs, like the EPOS Multi-Scale Laboratories data catalog.
4TU.ResearchData is an international data repository with a focus on data from science, engineering and technology. It holds the Data Seal of Approval and is run by the technical universities of Eindhoven, Delft and Twente via the 4TU.ResearchData Federation. Archiving, long-term preservation, sharing of research datasets, and resources for making data FAIR are some of the services offered by 4TU.ResearchData. EPOS-NL is working with 4TU.ResearchData to ensure that laboratory metadata from TU Delft published in 4TU.ResearchData will be discoverable via the EPOS Multi-Scale Laboratories data catalog.
ORFEUS Data center
The ORFEUS data center collects, archives and provides public access to seismological data (waveforms + metadata) from about 30 European seismic networks, and is the infrastructure for sharing seismic waveform data in EPOS’s Seismology Thematic Core Service. The ORFEUS Data Center is an important node in the European Integrated Data Archive (EIDA) – a federation of European and global data centers, aimed at sustainable storage and open access of seismological data.
There are several other sources of data in the EPOS-NL network.
The most comprehensive data portal to international paleomagnetic data is the MagIC web portal. Still, paleomagnetic data users may also be interested in UU-run paleomagnetic database, or in web-apps to calculate the paleoatitude or paleointensity of a given location on the world.
Seismological tomography mapping of the Earth’s crust and upper mantle
The first complete mapping of subducted plates in the Earth’s mantle and their geological interpretation is provided in the atlas of the underworld.
