Quaternary Sediment Cores from the Southern Fairway Basin (Tasman Sea)

The Southern Fairway Basin on the Lord Howe Rise in the Tasman Sea contains thick packages of Cretaceous and Tertiary sediment. Thirteen piston cores, collected by the RV L'Atalante in 1999 for the ZoNiCo 5 survey, were taken from depths between 1250 and 2753 meters below sea level to assess gas and petroleum potential. The cores document sediment, pore water, and gas composition in the shallow sedimentary section.

Use Cases

• Modeling gas hydrate stability zones based on sediment depth and composition.
• Investigating redox front formation and iron remobilization based on sediment color and magnetic susceptibility profiles.
• Assessing thermogenic hydrocarbon potential based on the presence of ethane, propane, and higher hydrocarbons.
• Correlating sediment color changes with pore water sulfate concentration and magnetic susceptibility data.

Strengths

• Contains 13 piston cores with documented lengths between 405 and 758 cm.
• Cores span a significant depth range from 1250 to 2753 meters below sea level.
• Description includes specific geochemical and physical properties analyzed, such as magnetic susceptibility and pore water sulfate.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes longer cores with less-oxidised sediment and additional analyses are needed for full understanding.
