25,000 sediment samples with 138,000 recorded properties form the MARS database, a collaborative project by the National Oceans Office and Geoscience Australia. Maps show sediment grain size distribution, classification, and carbonate content for the Northern Planning Area and Australian Marine Jurisdiction. The project identified gaps, with about 70% of the marine domain unmapped by measured sediment data.
Use Cases
- Model sediment mobility in shallow waters based on mean grain size data.
- Map seafloor sediment classification based on the Folk scheme.
- Analyze sediment data coverage gaps to prioritize future sampling efforts.
- Study carbonate content distribution across Australia's marine jurisdiction.
Strengths
- Database contains about 25,000 samples with 138,000 recorded properties.
- Maps were produced using validated quantitative data for two defined regions.
- The project critically assessed data quality and coverage on a national scale.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- About 70% of the total marine domain remains unmapped by measured sediment data.
- File formats are PDF and HTML, suggesting the primary data may not be in a structured tabular format.
