Quaternary Sediment Cores from the Southern Fairway Basin, Tasman Sea

Southern Fairway Basin on the Lord Howe Rise contains 13 piston cores recovered in 1999 by the RV L'Atalante. The cores, ranging from 405 to 758 cm long and from 1250 to 2753 meters below sea level, contain nannofossil ooze and were collected to document sediment, pore water, and gas composition. Geoscience Australia Data provides this dataset, which includes analyses of sediment color, magnetic susceptibility, and pore water chemistry.

Use Cases

• Modeling gas hydrate formation and distribution based on sediment core methane and hydrocarbon profiles.
• Investigating redox front processes and sediment diagenesis based on magnetic susceptibility and pore water sulfate data.
• Assessing petroleum potential based on thermogenic hydrocarbon signatures detected in the cores.
• Correlating sediment color changes with geochemical indicators like iron remobilization and pyrite formation.

Strengths

• Dataset includes 13 distinct sediment cores with documented lengths and water depths.
• Cores contain multiple measured parameters: sediment color, magnetic susceptibility, pore water sulfate, and methane/hydrocarbon concentrations.
• Collection details are specific, including the vessel (RV L'Atalante), year (1999), and survey name (ZoNiCo 5).

Limitations

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