Seabed Substrate map 1:250k


Seabed substrate map of the European marine areas including (e.g. the Baltic Sea, the Greater North Sea, the Celtic Sea, the Iberian Coast, and the Mediterranean Sea within EU waters) at 1: 250 000 scale (250k). The map is collated and harmonized from seabed substrate information within the EMODnet-Geology project.

Where necessary, the existing seabed substrate classifications (of individual maps) have been translated to a scheme that is supported by EUNIS. This EMODnet reclassification scheme includes at least five seabed substrate classes. Four substrate classes are defined on the basis of the modified Folk triangle (mud to sandy mud; sand; coarse sediment; and mixed sediment) and one additional substrate class (rock and boulders) was included by the project team. If the original seabed substrate dataset has enabled more detailed substrate classification, classifications with 7 and 16 substrate classes might be available.

The EMODnet-Geology project started in 2013 with 36 marine departments of the geological surveys of Europe (from 30 countries), with an objective to assemble marine geological information from all European sea areas. The seabed substrate map was produced October 2016.

Note: The data may include some errors e.g. data discontinuities.


Seabed Substrate map 1:1M


Seabed substrate map of the European sea areas (e.g. the Baltic Sea, the Barents Sea, the Greater North Sea, the Celtic Sea, the Iberian Coast, the White Sea, and the Mediterranean Sea within EU waters) at 1: 1 000 000 scale (1M). The map is collated and harmonized from seabed substrate information within the EMODnet-Geology project.

The map is collated from the 1M data from Partners and generalized 1:250k EMODnet data. Where necessary, the existing substrate classifications (of individual maps) have been translated to a scheme that is supported by EUNIS. This EMODnet reclassification scheme consists of altogether five seabed substrate classes.

Four substrate classes are defined on the basis of the modified Folk triangle (mud to sandy mud; sand; coarse sediment; and mixed sediment) and one additional substrate class (rock and boulders) was included by the project team. If the original seabed substrate dataset has enabled more detailed substrate classification, classifications with 7 and 16 substrate classes might be available. The seabed substrate map was produced October 2016.

Note: The data may include some errors e.g. overlays, topological gaps and data discontinuities.


Sediment Accumulation Rates


Sedimentation rate map of the European Seas (e.g. the Baltic Sea, the North Sea, the Barents Sea, the sea around Iceland, the Iberian Coast, the Western Mediterranean Sea (within EU waters), the Adriatic Sea, the Ionian Sea and the Central Mediterranean Sea (within EU waters), the Aegean-Levantine Sea (within EU waters – including the Turkish sector) and the Black Sea.

The map is collated and compiled within the EMODnet-Geology project. Estimations of modern sedimentation rates (cm/year) are based mainly on the 137Cs and the 210Pb dating. The 137Cs could be used as a time-marker in the sediment column. In the sediment column the activity peak of 137Cs corresponds to the fallout of the Chernobyl nuclear power plant accident of April 1986. Some sedimentation rates were estimated from acoustic-seismic and sediment core data.

This version was produced October 10th, 2016.

 

 


Sea-floor (bedrock) lithology


This map was derived and compiled from many larger scale data sources and has thus been generalized. It represents the lithology of marine bedrock of the IGME 5000 GIS and database at the time of plotting. The geological feature types are transferred after the OneGeology-Europe requirements, especially lithology was mapped into 1GE_Lithology.

 

 

 

 

 

 


Sea-floor (bedrock) stratigraphy


This map was derived and compiled from many larger scale data sources and has thus been generalized. It represents the stratigraphic units of marine bedrock of the IGME 5000 GIS and database at the time of plotting. The geological feature types are transferred after the OneGeology-Europe requirements, especially stratigraphic units was mapped into 1GE_Startigraphy according to the ICS 2009.

 

 

 

 

 

 


Coastal Behaviour

Coastal behaviour along the margins of the European Seas. The map was created using EUROSION project data (www.eurosion.org) as a baseline, updated by and supplemented with information from EMODnet-Geology partners. About 25% of the EUROSION information has been updated, and the total coastline for which migration data are available is more than 50% higher than before.

Three classes were defined: erosion (mean annual landward shift of ≥ 0.5 m), stable, and accretion (mean annual seaward shift of ≥ 0.5 m). The underlying monitoring periods vary in length. Different coastline marker were mapped, including high-water line, low-water line, dune foot, cliff top and base. Although the intended scale was 1:250,000, very few areas have been surveyed at the required longshore intervals of 250 m or less (translating to at least 1 data point per mm on the map).

 

 


Geological events and probabilities

Work package 6 “Geological events and probabilities”, led by the Geological Survey of Italy – ISPRA, represents data at 1:250,000 scale as polygons, lines and points. The use of different geometric features is related to the peculiar characteristics of each occurrence, as well as to the scale of representation:

  • submarine landslides (lines, polygons, points)
  • submarine volcanoes (lines, polygons, points)
  • tsunamis origin (points)
  • tsunamis affected coasts (points)
  • submarine tectonics (lines)
  • submarine fluid emissions of non volcanic origin (polygons, points)

Regarding earthquakes, it was decided to rely on the Seismic Portal of the European-Mediterranean Seismological Centre (EMSC) web-service (www.seismicportal.eu), which collects data supplied by national and international networks.

Data sources include detailed information held by the Project Partners plus any further publicly available third-party data (last update Dec. 2016).

All products delivered by Partners have been collected, 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.

Mineral occurrences


Example: Aggregate and Hydrocarbon resources on behalf of participating European partners. The Aggregate Resource layer has been complied by adapting European data at domain level to a harmonized pan European data model depicting resource areas, type and country codes. The Hydrocarbon Resource layer has been complied by adapting European data at domain level to a harmonized pan European data model depicting resource areas, type and country codes. Data can be requested from partners by contacting the data source owner provided in the data layer attribution.
