Seabed Geomorphology Vocabularies: Standardized Classification Scheme

Four linked vocabularies developed by the International Seabed Geomorphology Mapping Working Group (ISGM-WG) to support a standardized global seabed classification scheme. The vocabularies cover method terms, physiography, morphology features, and geomorphic units. Geoscience Australia published the vocabularies with permission from ISGM-WG.

Use Cases

• Standardizing seabed mapping terminology based on the provided method terms vocabulary.
• Classifying macroscale seabed shape and geology using the physiography vocabulary.
• Describing seabed shape features using the morphology feature vocabulary.
• Interpreting seabed morphology with process-based geomorphic unit classifications.

Strengths

• Based on a peer-reviewed, two-part classification scheme published in 2020 and 2023.
• Developed by an international working group (ISGM-WG) for global standardization.
• Includes four distinct, interlinked vocabularies covering different aspects of seabed description.

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 institutional bias inherent to the contributing working group.
