Data Sharing & Access
EPOS-NL makes solid Earth scientific data obtained by Netherlands-based researchers internationally, and centrally discoverable through the EPOS data portal.
What type of data would you like to share? Or access?
Laboratory data
EPOS-NL works with the European community EPOS Multi-Scale Labs (MSL) to provide central access to Earth scientific laboratory data of the following disciplines:
- Analogue modelling of geological processes
- Geochemistry
- Geo-energy test beds (e.g. field test facilities)
- Microscopy and Tomography
- Paleomagnetism
- Rock and melt physics
Did you know that EPOS Multi-Scale Labs includes ~100 European labs and is hosted at Utrecht University?
Share data
Do you have lab data from the above disciplines that you wish to share? The easiest way is to publish these as open access at one of the data repositories that are currently being harvested by EPOS-Multi-Scale Labs, a.o:
- Yoda Geo – see Tutorial
- 4TU.ResearchData
- GFZ Data Services
- MagIC (for paleomagnetic data)
- British Geological Survey
Ensure that we can easily find your data
When you publish data, you make it easier for us to find your data by adding “EPOS Multi-Scale Laboratories” as a keyword. And if you’re on a roll, it’s better still if you add keywords from the Multi-Scale Labs vocabularies.
Additional repositories are being added continuously. A full list of data repositories linked to EPOS-MSL is provided here. Did you, or are you planning to publish your lab data somewhere else, but you’d still like to link it to EPOS to maximize the international impact of your data? Contact us at info@epos-nl.nl, and we’ll try to help you.
Access data
Central access to laboratory data published accross Europe is being provided by the following data portals:
Seismological 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/
Share data
Sharing data of this type is primarily designed for large-scale seismological networks and stations. If you are not necessarily part of such a large-scale infrastructure, but you do wish to share data like these, have a look on the ORFEUS website, and/or contact Reinoud Sleeman (reinoud.sleeman@knmi.nl), or Jarek Bienkowski (jarek.bienkowski@knmi.nl). They can help you further.
Access data
Waveform data and station metadata can be accessed through the data portals below:
Supporting instructions on how to access data at EIDA can be found here. Most data made available in EIDA can also be found in EPOS, where these are presented alongside data from other Earth scientific disciplines.
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:
Data type | Provided by | Accessible at |
|---|---|---|
Seismological data | KNMI | ORFEUS Data Center (KNMI) |
Seismological data | NARS (UU) | ORFEUS Data Center (KNMI) |
Groningen geological model (Petrel) | NAM | Yoda (UU) |
Distributed Strain Sensing (DSS) data Zeerijp well 2015-2021 | NAM | Yoda (UU) |
Reservoir core photographs | NAM | Yoda (UU) |
Seismological data flexible network and downhole geophones | NAM | KNMI data platform |
Mmax II workshop data | NAM | Yoda (Geo) |
Microstructural data Stedum-1 and Zeerijp-3a | UU | Yoda (Geo) |
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.
Data type | Provided by | Accessible at |
|---|---|---|
Subsurface pressure and temperature database Netherlands | EBN and TNO | EBN Data Centre |
Integrated catalogue of geological data of the Netherlands (Petrel) | UU | Yoda (UU) |
Shallow compaction data Groningen gas field and other locations in the Netherlands | NAM | Yoda (UU) |
For supporting instructions on how to access the seismological data at the ORFEUS Data Center please click here.
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.
Data centers
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).
Yoda Geoscience
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
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.
Other data
There are several other sources of data in the EPOS-NL network.
Paleomagnetic data
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.
