Over 400 standardized geomorphic terms across 11 overlapping classes provide a hierarchical framework for seabed mapping. The International Seabed Geomorphology Mapping Working Group developed this two-part approach, separating 40 bathymetric shapes from stratigraphic interpretation. This open-access framework aims to support consistent terminology from global to local scales for the UN Decade of Ocean Science.
Use Cases
- Classifying seabed morphology based on the standardized list of 40 bathymetric shapes.
- Assigning geomorphic interpretation using the hierarchical framework of over 400 terms.
- Tailoring marine habitat maps to specific data quality and application needs using the Setting/Process to sub-type classification levels.
- Supporting cross-disciplinary analysis by integrating established terminologies from different marine sub-disciplines.
Strengths
- Framework developed through an Ocean Best Practice process incorporating science-community input.
- Includes a glossary of over 400 standardized terms across 11 overlapping geomorphic classes.
- Separates morphological mapping of 40 bathymetric features from interpretive geomorphic classification to constrain uncertainty.
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 or source bias inherent to the contributing scientific community.
