Seabed substrate 1:250 000
Seabed substrate 1:250 000 is one of the products produced in the EMODnet (European Marine Observation and Data network) Geology EU project. Project provided seabed geological material from the European maritime areas. The EMODnet Geology project ( http://www.emodnet-geology.eu/) collects and harmonizes geological data from the European sea areas to support decision-making and sustainable marine spatial planning. The EMODnet Geology partnership has included 36 marine organizations from 30 countries.
This data includes the EMODnet seabed substrate map at a scale of 1:250 000 from the Finnish marine areas. It is based on the data produced on a scale of 1:20 000 by the Geological Survey of Finland (GTK), which does not cover the whole Finnish marine area yet. The seabed substrate data will be updated with a new interpreted data on a yearly basis.The data has been harmonized and reclassified into five Folk substrate classes (mud, sandy clays, clayey sands, coarse sediments, mixed sediments) and bedrock. The data describes the seabed substrate from the uppermost 30 cm of the sediment column. The data have been generalized into a target scale (1:250 000). The smallest smallest cartographic unit within the data is 0.3 km2 (30 hectares).
Further information about the EMODnet-Geology project is available on the portal ( http://www.emodnet-geology.eu/).

- Purpose
-
The data has been created for the decision-making, research and large-scale marine spatial planning.
The material is produced on a 1: 250 000 scale and it describes the seabed substrate at a general level only, and is not suitable for a detailed analysis. The data does not cover the whole Finnish marine area yet and it will be updated with a new interpreted data on a yearly basis. The data tells the seabed substrate composition from the surface to 30 cm depth.
The restricted areas (Defence Forces) have been removed from the material.

The material has been edited from the marine geological data produced at the scale of 1:20 000 by GTK data. GTK's seabed mapping program has collected marine geological data since the 1970s. Data quality and accuracy has improved over the years, as methods and positioning accuracy has improved trough years. The marine geological data (1:20 000) does not cover the whole Finnish marine area yet and the dataset will be updated with a new interpreted data on a yearly basis.
This material is reclassified from the Finnish marine geological data to Folk sediment classification system based on expert-estimations. Folk sediment classification is an international accepted classification system based on particle size distribution.
The data have been generalized into a target scale (1:250 000). The smallest smallest cartographic unit within the data is 0.3 km2 (30 hectares).
The restricted areas (Defence Forces) have been removed from the material.
