A 2020 glossary update provides marine scientists with a standardized system for seabed classification. The glossary includes feature definitions and schematic diagrams, developed through a collaboration between marine mapping programs in Norway, Ireland, the UK, and Australia. It is intended to minimize ambiguity and support clear, consistent characterization of seabed morphology.
Use Cases
- Standardizing seabed feature descriptions based on the provided glossary definitions.
- Training machine learning models for automated seabed classification using the defined morphology categories.
- Supporting marine spatial planning and habitat mapping by providing a consistent terminology framework.
- Annotating bathymetric and sonar survey data with standardized geomorphological labels.
Strengths
- Glossary is the result of an international collaboration between four major marine mapping programs.
- Includes representative schematic diagrams alongside feature definitions to support clear classification.
- Builds upon and updates a prior 2016 classification scheme, incorporating new terms.
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.
Provenance
- Source
- Collaboration between marine geoscientists from MAREANO (Norway), INFOMAR (Ireland), MAREMAP (UK), and Geoscience Australia (MIM-GA).
- Collection Method
- Glossary terms and definitions are primarily drawn from the IHO guide for undersea feature names, modified and augmented.
- Freshness
- Last updated 2026-06-16 21:22:56.195031; freshness should be verified.
- Geography
- Global, based on international standards.
