North-West European Continental Shelf Sediment Composition Predictions

The north-west European continental shelf is covered by spatial predictions of mud, sand, and gravel fractions as continuous variables. The dataset includes raw raster predictions of these fractions, derived classifications using multiple sediment schemes, and accompanying error or accuracy maps for each prediction. It was published by the Government Digital Service on the eu_open_data platform.

Use Cases

• Modeling seabed habitat suitability based on predicted sediment classifications like EUNIS level 3.
• Analyzing sediment transport patterns using continuous fraction predictions of mud, sand, and gravel.
• Assessing prediction uncertainty for geological models using the provided Root-Mean-Squared-Error layers.
• Comparing sediment composition across classification schemes such as Folk 5, 7, 11, and 15.

Strengths

• Includes multiple sediment classification schemes (EUNIS level 3, Folk 5, 7, 11, 15) for comparative analysis.
• Provides separate raster layers for prediction error (Root-Mean-Squared-Error) and classification accuracy.
• Predictions cover a defined geographic region: the north-west European continental shelf.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count and file size are unknown, which may limit suitability assessment.
