Chemical Composition of Manganese Nodules from the Cape Leeuwin Field

A 16 percent average water content was determined for manganese nodules after drying at 105°C. This dataset from the Australian Ocean Data Network summarizes chemical analyses of nodules from a field southwest of Western Australia, with metal values recalculated to account for moisture. The data originates from a preliminary report published in 1977 and was last updated in April 2026.

Use Cases

• Comparing metal concentrations based on standardized drying procedures mentioned in the description
• Analyzing the geochemical variability of manganese nodules from a specific oceanic field
• Modeling the resource potential of marine mineral deposits using summarized chemical data
• Calibrating analytical methods for moisture content in geological samples

Strengths

• Data includes metal values recalculated for a standardized 16 percent moisture content, enabling direct comparison
• Chemical analyses were performed using atomic absorption spectrophotometry, a recognized analytical technique

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the single study area off Western Australia
