Manganese Nodule Geochemistry from the Cape Leeuwin Field, Western Australia

A 1977 preliminary report on a manganese nodule field southwest of Western Australia includes chemical analyses. Metal values were recalculated to account for a determined average moisture content of 16 percent after drying at 105°C. The data, summarized in an accompanying table, originates from Geoscience Australia.

Use Cases

• Analyzing metal concentrations in seabed nodules based on reported chemical data.
• Comparing geochemical signatures of nodules from different ocean fields based on the described location.
• Studying the impact of sample preparation (drying temperature) on reported elemental analysis values.

Strengths

• Chemical analyses were performed using atomic absorption spectrophotometry.
• Data addresses a known methodological issue by recalculating values for a consistent 16% moisture content.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The underlying data is from a 1977 report; freshness should be verified for contemporary applications.
