A 2026 publication by the International Seabed Geomorphology Mapping Working Group presents a standardized classification framework for marine and coastal landforms. The framework includes a glossary of over 400 terms across 11 classes and maps 40 bathymetric shapes, developed through an Ocean Best Practice process. It aims to support consistent global mapping for evidence-based ocean decision-making.
Use Cases
- Standardizing seabed mapping terminology across jurisdictions based on the hierarchical framework.
- Classifying bathymetric shapes using the 40 standardized Morphology Feature terms.
- Tailoring geomorphic interpretation to data quality using the Setting/Process to sub-type hierarchy.
- Integrating existing marine lexicons into machine-readable vocabularies for GIS tools.
Strengths
- Framework developed through a formal Ocean Best Practice process incorporating science-community input.
- Glossary contains over 400 standardized terms across 11 overlapping geomorphic classes.
- Part 1 of the approach maps and classifies 40 distinct bathymetric shapes.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last updated metadata is from 2026-05-05.
