Seabed Geomorphology Vocabularies: Standardized Classification Scheme

The International Seabed Geomorphology Mapping Working Group developed a two-part seabed geomorphology classification scheme. This dataset includes four linked vocabularies published by Geoscience Australia to support the scheme's implementation. The vocabularies cover method terms, physiography, morphology features, and geomorphic units.

Use Cases

• Standardizing seabed mapping terminology based on the published classification scheme.
• Classifying seabed morphology features based on the Part 1 Morphology vocabulary.
• Interpreting seabed processes based on the Part 2 Geomorphology vocabulary framework.
• Integrating legacy seabed physiographic terms based on the Harris et al. (2014) vocabulary.

Strengths

• Based on a formally published, two-part classification scheme (Dove et al., 2020; Nanson et al., 2023).
• Includes four distinct, interlinked vocabularies covering method, physiography, morphology, and geomorphic units.
• Published by Geoscience Australia with permission from the international working group.

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 methodological bias inherent to the source working group.
