Seabed Morphology Features Glossary from International Marine Mapping Programs

A glossary of seabed morphology features provides standardized definitions and schematic diagrams for marine scientists. It updates a 2016 classification scheme and results from a collaboration between marine mapping programs in Norway, Ireland, the UK, and Australia. The glossary is intended to support clear and consistent seabed characterization.

Use Cases

• Standardizing seabed feature descriptions based on the provided glossary of morphology terms.
• Training machine learning models for automated seabed classification based on defined feature schematics.
• Annotating marine geospatial datasets using the consistent terminology from the international guide.
• Supporting comparative analysis of seabed morphology across different marine regions.

Strengths

• Glossary is the result of an international collaboration between four national marine mapping programs.
• Includes representative schematic diagrams for each feature to support clear classification.
• Updates and modifies terms from the authoritative IHO guide for undersea feature names.

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.
