SS2011_06: Dredge Rock Samples from the Perth Abyssal Plain

Dredge rock samples were recovered during scientific voyage SS2011_06 on the MNF RV Southern Surveyor. The samples originate from the Perth Abyssal Plain offshore Western Australia, specifically from the Batavia Knoll, Gulden Draak Ridge, and Dirck Hartog Ridge. The dataset is managed by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Classify continental rock types such as gneiss, granite, and sandstone based on sample descriptions.
• Map the distribution of mafic rocks like gabbro and basalt across different dredge sites on the seafloor ridges.
• Analyze the geological history of the Perth Abyssal Plain based on the recovered rock assemblage.

Strengths

• Sample locations are specified for distinct geological features: Batavia Knoll, Gulden Draak Ridge, and Dirck Hartog Ridge.
• Rock types are explicitly listed, including gneiss, granite, sandstone, gabbro, and basalt.
• Data is associated with a specific, documented scientific voyage (SS2011_06) on the RV Southern Surveyor.

Limitations

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