Chemical Composition of Manganese Nodules from Cape Leeuwin, Western Australia

A 16 percent average moisture content was determined for manganese nodules after drying at 105°C. The dataset contains recalculated metal values from atomic absorption spectrophotometry, assuming this moisture content, for nodules southwest of Western Australia. The data originates from the Australian Ocean Data Network and was referenced in a 1977 journal report.

Use Cases

• Analyze corrected metal concentrations based on standardized moisture content.
• Compare geochemical signatures of manganese nodules from different ocean fields.
• Model mineral resource potential based on recalculated assay data.

Strengths

• Chemical analyses are recalculated using a standardized 16 percent moisture content, improving comparability.
• Data is associated with a specific geographic field (Cape Leeuwin) and a referenced scientific report.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection after download.
