Chemical Composition of Manganese Nodules from the Cape Leeuwin Field

A 1977 preliminary report on a manganese nodule field off Western Australia includes chemical analyses recalculated for a 16% moisture content. The data, provided by the Australian Ocean Data Network, likely contains metal values measured by atomic absorption spectrophotometry. This dataset was last updated on June 5, 2026.

Use Cases

• Compare metal concentrations based on different sample drying methods mentioned in the description.
• Analyze the geochemical signature of manganese nodules from a specific offshore field.
• Study the relationship between moisture content and reported elemental values in geological samples.

Strengths

• Chemical data has been recalculated to a standardized 16% moisture content, enabling direct comparison.
• Analytical method (atomic absorption spectrophotometry) for metal values is specified in the description.

Limitations

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