Geochemistry of Southern Australian Continental Margin Sediments

Eight gravity cores from the Southern Australian continental margin were analyzed for porewater metabolites, major and trace elements, and radiochemical data. The data were collected during Bureau of Mineral Resources survey 67 and analyzed both at sea and in Canberra. These analyses provide clues to geochemical processes important for identifying seafloor mineral formations like manganese crusts and phosphorites.

Use Cases

• Assess long-term environmental change based on porewater and trace element data.
• Study Late Quaternary paleoceanography based on radiochemical species like authigenic uranium.
• Investigate processes for manganese crust and nodule formation based on sedimentary manganese inventory and pore water data.
• Model organic carbon burial and recycling based on pore water oxygen character data from core-tops.

Strengths

• Data includes analyses from eight distinct gravity cores.
• Analyses cover multiple complementary geochemical domains: porewater metabolites, major/trace elements, and radiochemistry.
• Data is part of a larger geochemical database for the Australian continental margin.

Limitations

• Row count and dataset scale are unknown.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified despite a future last updated date.
