A 2026 publication by the International Seabed Geomorphology Mapping Working Group details a standardized framework for classifying marine and coastal landforms. The framework includes a glossary of over 400 terms across 11 classes and a process for mapping 40 bathymetric shapes. It is published by the Australian Ocean Data Network to support globally consistent seabed mapping.
Use Cases
- Standardizing seabed geomorphic terminology across global datasets based on the hierarchical framework.
- Mapping bathymetric shapes using the 40 standardized Morphology Feature terms described.
- Assigning geomorphic interpretations from Setting/Process to basic geomorphic unit sub-types as data quality allows.
- Supporting interdisciplinary analysis by integrating established marine sub-discipline lexicons into a single framework.
Strengths
- Framework developed through an Ocean Best Practice process incorporating science-community input.
- Includes a glossary of over 400 standardized geomorphic terms across 11 overlapping classes.
- Separates morphological mapping (40 shapes) from geomorphic interpretation to constrain uncertainty.
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.
