Seabed Morphology Features Glossary for Marine Geoscientists

A glossary of seabed morphology features provides standardized definitions and schematic diagrams for marine scientists. The glossary updates a 2016 classification scheme and results from a collaboration between mapping programs in Norway, Ireland, the UK, and Australia. Feature terms are primarily drawn from the IHO guide for undersea feature names, modified and augmented to cover observed seabed diversity.

Use Cases

• Standardizing seabed feature descriptions based on the provided glossary of morphology terms.
• Training machine learning models for automated seabed classification based on feature definitions and diagrams.
• Supporting consistent marine habitat mapping based on the updated geomorphology classification scheme.
• Integrating seabed morphology data from different national mapping programs using a common terminology.

Strengths

• Glossary entries include both a feature definition and a representative schematic diagram.
• Developed through international collaboration between marine mapping programs in four countries.
• Feature terms are based on the authoritative IHO guide, modified and augmented for completeness.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a glossary document (HTML), not a structured data table of observations.
