Two manganese nodules were recovered from the Tasman Sea southeast of Sydney at a depth of 4300 meters. They were collected by HMAS Kimbla and are associated with calcareous mud deposited below the lysocline. The nodules are subspherical, about 10 cm in diameter, and have a high clay content with specific low metal concentrations.
Use Cases
- Analyze manganese nodule morphology based on described subspherical shape and 10 cm diameter
- Study deep-sea sediment composition based on association with greenish gray calcareous mud
- Compare metal concentrations in nodules based on provided Ni, Cu, and Co percentages
- Model mineral deposit formation based on data from a specific location (155° 35E, 36° 15S) and depth (4300 m)
Strengths
- Provides precise geographic coordinates (155° 35E, 36° 15S) and depth (4300 m)
- Includes specific chemical composition percentages for Ni (0.25%), Cu (0.17%), and Co (0.06%)
- Describes physical characteristics like nodule shape (subspherical) and diameter (about 10 cm)
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 bias inherent to a single collection site
