Deep-Sea Sediments and Manganese Nodules from the Southern Tasman Sea, 1979

Southern Tasman Sea sediment and nodule samples collected during a 1979 geological cruise on HMAS Kimble. The dataset includes details from five stations, with two manganese nodules analyzed for metal content (Ni 0.25%, Cu 0.17%, Co 0.06%) and recovered from a depth of 4300 m near Gascoyne Seamount. Data is provided by the Australian Ocean Data Network.

Use Cases

• Analyze manganese nodule composition based on reported Ni, Cu, and Co percentages.
• Study sediment distribution patterns based on the described recovery of reddish brown clay and grey calcareous mud from different depths.
• Model the carbonate compensation depth in the region based on the stated 4500 m depth.
• Investigate the relationship between nodule formation and oceanographic conditions based on the suggested link to low sedimentation rates and oxidising conditions.

Strengths

• Includes specific geochemical data for two nodules (Ni 0.25%, Cu 0.17%, Co 0.06%).
• Provides precise geographic context, including depths (4300 m, 4900-5100 m) and location near Gascoyne Seamount.
• Describes sampling methodology from five stations during a defined cruise in May 1979.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic/temporal bias inherent to a single 1979 cruise.
