Geochemistry of Southern Australian Continental Margin Surface Sediments

Eight gravity cores from the Southern Australian Continental Margin were analyzed for porewater metabolites, major and trace element abundances, and radiochemical data. The dataset, part of Bureau of Mineral Resources survey 67, provides a record for assessing long-term environmental change and Late Quaternary paleoceanography. It forms part of a broader geochemical database for the Australian continental margin.

Use Cases

• Assess long-term environmental change from anthropogenic discharges based on porewater and trace element data.
• Reconstruct Late Quaternary paleoceanographic conditions based on radiochemical species like authigenic uranium.
• Investigate geochemical processes for seafloor mineral formation based on manganese and silicate data.
• Model organic carbon burial and recycling rates based on pore water oxygen and metabolite profiles.

Strengths

• Includes data from eight distinct gravity cores analyzed both at sea and in a laboratory.
• Covers multiple geochemical domains: porewater metabolites, major/trace elements, and radiochemistry.
• Provides a basis for systematic analysis of geochemical controls on sediments around Australia.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update is 2026-06-16.
