The sediments layer is a static layer, it can help in decision making to plan for wind farms or other structures fixed to the sea floor. It can also assist in identifying potentially important areas for protection. | |||

The geometries within the North Sea areas were selected and values were attributed to each sediment type present in the area. Then the attributes values were used to rasterise the data. The raster data layer was then reprojected to Lambert's Azimuthal Equal Area (EPSG:3035) projection. | The geometries within the North Sea areas were selected and values were attributed to each sediment type present in the area.

== North Sea Digital Twin Edition == | |||
=== Description === | |||
In the North Sea Digitial Twin Edition, the sediments layer is retrieved from Emodnet. The name of the layer is 'Seabed Substrates 1:1M' and represent the different types of sediments to be found on the seabed. | |||
The map is collated from data from Partners and generalized data at smaller scales. 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. | |||
The seabed substrate maps were produced March 2019. The sedimentation rates April 2021. The maps are updated automatically through an [https://drive.emodnet-geology.eu/geoserver/gtk/wms WMS] connection with Emodnet. | |||

This layer was adapted for MSP Challenge integration. The photic and non-photic zones were merged to obtain just the sediments' classes: sand, mud and clay, and hard bottom. | This layer was adapted for MSP Challenge integration.
