The Australian Ocean Data Network provides data on seabed and suspended sediment composition and distribution in north and central Torres Strait, Australia. The dataset includes sedimentological and geochemical properties, such as Cu/Al ratios, to investigate links between sediment sources and widespread seagrass dieback. The data was last updated on April 16, 2026.
Use Cases
- Investigating terrigenous versus marine sediment sources based on aluminosilicate and carbonate phase dominance
- Analyzing copper enrichment in sediments based on Cu/Al ratios mentioned in the description
- Modeling sediment transport pathways to assess potential impacts on seagrass health
- Comparing sediment composition between northern (Saibai Island) and central (Turnagain Island) regions of Torres Strait
Strengths
- Includes specific geochemical metrics, such as mean Cu/Al ratios of 0.01 near Saibai Island and 0.02 near Turnagain Island
- Provides sedimentological classifications, such as poorly sorted muddy sand and moderately sorted carbonate sand
- Data is linked to a specific environmental investigation concerning seagrass dieback in Torres Strait
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
