Coastal to Deep-Marine Geomorphic Classification Framework

A standardized hierarchical framework developed by the International Seabed Geomorphology Mapping Working Group (ISGM) to support globally consistent mapping. The framework separates morphological mapping of 40 bathymetric shapes from geomorphic interpretation using a glossary of over 400 terms across 11 overlapping classes. It is published in Earth-Science Reviews (2026) and supported by open-access digital vocabularies and GIS tools.

Use Cases

• Standardizing seabed geomorphic terminology based on the hierarchical framework and glossary of over 400 terms.
• Mapping bathymetric shapes based on the 40 standardized Morphology Feature terms.
• Tailoring geomorphic classification based on the Setting/Process, BGU, BGU-T, and BGU-sT hierarchy.
• Integrating existing marine geomorphic lexicons based on the open-access, machine-readable digital vocabularies.

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 (Part 1) from geomorphic interpretation (Part 2) 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.
• Freshness should be verified; last updated 2026-04-16 14:11:44.766061.
