Seabed Geomorphology Vocabularies: Standardized Classification Terms

The International Seabed Geomorphology Mapping Working Group (ISGM-WG) developed a two-part seabed geomorphology classification scheme. This product includes four linked vocabularies of terms to support standardized global seabed mapping, published by Geoscience Australia. The vocabularies were last updated on 2026-05-05.

Use Cases

• Standardizing seabed map annotations based on the provided morphology and geomorphology terms.
• Classifying seabed features by process interpretation using the structured framework of geomorphic units.
• Integrating macroscale seabed shape descriptors using the retained physiographic vocabulary.
• Implementing a consistent global seabed classification scheme based on the linked vocabularies.

Strengths

• Based on a formally published two-part classification scheme (Dove et al., 2020; Nanson et al., 2023).
• Includes four distinct, linked vocabularies covering method terms, physiography, morphology, and geomorphology.
• Developed by an international working group (ISGM-WG) to facilitate standardized global mapping.

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.
• Row count is unknown, which may limit suitability assessment.
