The quality flagging represents a score of the most occurring sediment type in the core (sample).

Analysis in progress

At this moment we propose a score of 3 out of 5 for the visual description. We are still developing a most appropriate scoring for other analyses techniques.

Help

Straight access through GIS Software

All our data can be accessed using GIS software QGIS, ArcGIS, etc using a WFS service located at BMDC WFS Service. The relevant layers are

  • TILES Cores

Where am I?

You are visiting the data portal on marine geological data as developed within TILES, a Belgian Science Policy (Belspo) project on
‘Transnational and Integrated Long-term Marine Exploitation Strategies’.
On our website ( TILES ) you can find our approach on how we want to manage our seabed resources now and in the future.
Essential in this process is sharing information on the geological resource itself.

What to find?

We have been compiling historical data on surface and subsurface lithology of the Belgian and southern Netherlands part of the North Sea.
Here, you can find the Belgian data. The Dutch data can be found at the DINO, data portal developed by our colleagues from the TNO.

What can I do here?

You can navigate around a map by dragging to pan and scrolling to zoom whilst displaying locations where lithological descriptions are available.
Some of the functionalities:

  • In the Map tab define a polygon from which you want to extract data.
  • Use the Search Form to add any condition, other than the polygon itself, and Execute Search.
  • Go to the Result Tab to find an overview of all information matching your criteria.
  • Here you can Download a zip file containing:
    • A pdf file with the original core or sample description

    • A pdf file with grain-size information when available (presently for cores only)

    • A pdf file containing pictures when available (presently for cores only)

    • Standardized excel sheet of the lithological information (see below)

    • Standardized excel sheet of the grain-size information (in progress)

Straight access through GIS Software

All our data can be accessed using GIS software pointing at url Tiles data in EARS. The relevant layers are

  • TILES Cores

Standardization

Metadata and lithological descriptions have been coded following European standards, e.g.:

Terms of use

Information is free for use without any application procedure or formalities such as registrations and logins.
Only non-confidential data are shown.
Users are responsible for ensuring that the format of the records is compatible with their computer system and expected to operate a suitable anti-virus software when downloading the data.
Information content will change with future additions, updates and data portal developments.
This will be indicated as a new version or new modification date on the data portal and its derived data products.

Liability

RBINS gives no warranty as to the quality or suitability of the data. Incompleteness, errors or contradictions are possible, uncertainties are sometimes high.
Confirmation with further and more recent detailed research is always needed.
RBINS is not responsible for further actions done with the data, nor for the consequences of any use whatsoever.

Ownership and copyright

Reference should be made to the data originator for the original data. For the use of the database and standardized data sheets reference should be made to:

Kint, L. and Van Lancker, V. (2018). SediLITHO@SEA (31/08/2018).
Database lithological descriptions, with relevance to Belgian part of the North Sea. Brussels: Royal Belgian Institute of Natural Sciences.

Most of the digitized data consists of outdated or open (Federal and Flemish) authority reports or records.
A major contribution was made by TNO Geological Survey of the Netherlands.
Industry data are also added and were used in our data modelling ( Tiles-DSS), however the majority is still flagged confidential in the data portal.
