West Hebrides Biotope Mapping: Marine Habitat Classification for Scotland

The West Hebrides Biotope Mapping Project integrates multibeam echosounder, acoustic ground discrimination, underwater video, and grab data to map rocky reef habitats west of Scotland's Outer Hebrides. Biotopes are classified using the National Marine Habitat Classification for Britain and Ireland (Connor et al., 2004). The dataset is provided by the Joint Nature Conservation Committee and was last updated on 2026-04-14.

Use Cases

• Classify marine biotopes based on integrated acoustic and visual survey data mentioned in the description
• Model habitat distribution for rocky reef ecosystems based on the described GIS and multibeam data
• Validate or extend the National Marine Habitat Classification system using the project's ground-truthed data

Strengths

• Uses a standardized classification system (National Marine Habitat Classification for Britain and Ireland)
• Integrates multiple data sources: multibeam echosounder, AGDS, video, and grab samples
• Project methodology is documented in a formal JNCC report (Report No 424)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the specific study area west of the Outer Hebrides
