Seabed Morphology Features Glossary for Marine Classification

A 2020 update to the seabed geomorphology classification scheme presents a glossary of seabed morphology features. The glossary is intended to provide marine scientists with an accurate way to characterise the seabed, with entries including definitions and schematic diagrams. It results from a collaboration between marine mapping programmes in Norway, Ireland, the UK, and Australia.

Use Cases

• Standardising seabed characterisation based on the provided morphology feature glossary.
• Training machine learning models for automated seabed feature identification based on defined terms.
• Supporting consistent annotation and labeling in marine geospatial datasets using the classification scheme.
• Integrating seabed morphology terminology across international marine mapping programs.

Strengths

• Glossary entries include a feature definition and a representative schematic diagram for clarity.
• Feature terms and definitions are drawn from the IHO guide for undersea feature names and have been modified and augmented.
• The classification is the result of a collaboration between marine mapping programs in four countries (Norway, Ireland, UK, Australia).

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; it does not contain raw observational or measurement data.
