Overview of all boreholes in the Dutch part of the North Sea and Wadden Sea, and in the Scheldt estuary. For each borehole, measurements and descriptions of each described interval are provided through an information link. This information concerns main lithology; gravel, sand, silt and clay admixture; main and secondary colour; sediment consistency; gravel and sand median class; and gravel, sand, silt, lutum, mud, shell and organic-matter percentage.

Pan-European coastline-migration map at zoomable scale. The map is collated and harmonized from field-monitoring data and aerial photography provided by partners of EMODnet Geology. Where no such coastline-migration data were available, information from the EUROSION project is provided. For remaining gaps, please consult the coastline-migration map based on satellite data. The main attributes denote degree of landward (by erosion or submergence) or seaward (by accretion or emergence) change. In the visualization provided, three classes are distinguished: landward migration, stable coastline, seaward migration. The criterion for stable coastlines is ≤0.5 meter net change per year over a 10-year period. The current version was finalized in January 2021.

Quaternary –age This web map service shows the chronostratigraphic age of geological units of the seafloor originated in the Quaternary period (i.e. 2,588 Ma from now until today). The data were compiled by BGR from the EMODnet geology partner organisations in the EMODnet Geology project phases II and III between 2009 and 2019. The scale varies between 20 000 and 2 500 000. Quaternary -lithology This web map service shows the rock type (lithology) of geological units of the seafloor originated in the Quaternary period (i.e. 2,588 Ma from now until today). The data were compiled by BGR from the EMODnet geology partner organisations in the EMODnet Geology project phases I, II and III between 2009 and 2019.

Pre-Quaternary - Lithology. This web map service shows the geological units of the seafloor originated earlier than 2,588 Ma from now (pre-Quaternary). International Geological Map of Europe and Adjacent Areas (Asch, 2005). The scale varies between 25,000 and 5 000 000.The data were compiled by BGR from the EMODnet geology partner organisations in the EMODnet Geology project between 2009 and 2021

This database contains information on reserved and non-reserved mineral deposits, prognosticated mineral resources, exhausted and abandoned deposits and resources, non-prospective areas, negative results of exploration, and geographic location of mineral resources.

These datasets represent a systematic collection of harmonized data concerning geological events. GIS layers display data on the Portal at a resolution of 1:100,000 and 1:250,000 scale concerning earthquakes, submarine landslides, volcanoes, tsunamis, fluid emissions and Quaternary tectonics, subdivided according to their geometry (polygons, points and lines). They provide information on the type of events which have taken place in the past and might potentially occur again. Where available, details include dimensions, state of activity, morphological type and lithology. The elaboration of guidelines to compile GIS layers was aimed at identifying parameters to be used to thoroughly characterize each event. Particular attention has been devoted to the definition of the Attribute tables in order to achieve the best degree of harmonization and standardization complying with the European INSPIRE Directive. Shapefiles can be downloaded from the Portal and used locally in order to browse through the details of the different features, consulting their Attribute tables. Information contained therein provide an inventory of available data which can be fruitfully applied in the management of coastal areas and support planning of further surveys. By combining the diverse information contained in the different layers, it might be possible to elaborate additional thematic maps which could support further research. Moreover, they potentially represent a useful tool to increase awareness of the hazards which might affect coastal areas. Data sources include detailed information held by the Project Partners plus any further publicly available third-party data (last update Sep. 2021). All products delivered by Partners have been collated, verified and validated in order to achieve the best degree of harmonization and INSPIRE compliance. Each layer is complemented by an Attribute table which provides, in addition to the location, type of geological event and its references (mandatory), further information for each occurrence (where available). Since features considered within WP6 have a scattered distribution, the additional layer “Geological events distribution” provides basic information on areas of occurrences, no occurrences and no data for the marine areas surrounding European countries.

Pan-European map of morphological and lithological coastal type at zoomable scale. The map is collated and harmonised from geological maps provided by partners of EMODnet Geology. Where no such data were available, information from the EUROSION project is provided. The main attributes denote several types of rocky coast, beach, inshore area and artificial coast. The current version was finalised in May 2021.

The European Marine Observation and Data Network (EMODnet) consists of more than 100 organisations assembling marine data, products and metadata to make these fragmented data resources more available to public and private users relying on quality-assured, standardised and harmonised marine data which are interoperable and free of restrictions on use. EMODnet is currently in its fourth phase. BGR participates in the EMODnet Geology theme and is coordinating the “seafloor geology” work package from the beginning. In cooperation with the project partners BGR compiles and harmonises GIS data layers on the topics geomorphology, pre-Quaternary and Quaternary geology and provides those, based on INSPIRE principles, via the EMODnet Geology portal https://www.emodnet-geology.eu/map-viewer/. These map layers present the pre-Quaternary and the Quaternary sea-floor geology and Geomorphology of the European Seas, semantically harmonized based on the INSPIRE data specifications for Geology, including the terms for lithology, age, event environment, event process. The data are compiled from the project partners, the national geological survey organizations of the participating countries. The data set represents the most detailed available data compilation of the European Seas using a multi-resolution approach. Data completeness depending on the availability of data and actual mapping campaigns. This open and freely accessible product was made available by the EMODnet Geology project (https://www.emodnet-geology.eu/), implemented by EMODnet Geology Phase IV partners, and funded by the European Commission Directorate General for Maritime Affairs and Fisheries. These data were compiled by BGR from the EMODnet IV Geology partners. All ownership rights of the original data remain with the data originators, who are acknowledged within the attribute values of each map feature.
