West Shetland Shelf Benthic Habitat Map Based on Acoustic Data and EUNIS Classification

Joint Nature Conservation Committee produced seabed habitat maps for the West Shetland Shelf area in 2013. The maps classify benthic habitats using a top-down rule-based approach and a bottom-up object-based approach, integrating acoustic, bathymetry, and backscatter data. Habitat polygons are labeled according to the Marine Habitat Classification for Britain and Ireland (MNCR) and translated to EUNIS codes, with accompanying confidence assessments.

Use Cases

• Classifying seabed habitats based on acoustic datasets and the MNCR/EUNIS classification hierarchy mentioned in the description.
• Assessing habitat mapping confidence for specific areas using the MESH confidence assessment method described.
• Supporting Marine Protected Area (MPA) proposal analysis with the three detailed habitat maps produced for each area.
• Integrating seabed substrate information from the British Geological Survey (BGS) for broader marine spatial planning.

Strengths

• Includes a confidence assessment for each habitat map using the established MESH method.
• Habitat classification is linked to two standardized systems: the MNCR classification and the EUNIS code translation.
• Maps were generated using a combined top-down (rule-based) and bottom-up (object-based, supervised) methodology.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The level of habitat detail was restricted to level 3 or 4 of EUNIS and level 2 or 3 of MNCR, not the most detailed possible.
