Scott Plateau to Java Trench Marine Survey Data from 1977

A 1977 survey by the R.V. Valdivia collected geoscientific data between Scott Plateau off northwest Australia and the Java Trench. The survey recorded 1700 km of seismic data, 2550 km of bathymetric, gravity, and magnetic data, and obtained 31 bottom samples from depths of 2000 m to 5800 m. The dataset provides insights into continental structure, sediment layers, and paleoceanographic conditions.

Use Cases

• Analyze tectonic fault patterns based on described NW to WNW fault directions on the Scott Plateau.
• Model sediment deposition rates based on described Holocene and Pleistocene sedimentation rates.
• Study paleoceanographic conditions based on calcite compensation depth data from core samples.
• Map submarine geomorphology based on bathymetric data covering canyons, the Wilson Spur, and the Roti Basin.

Strengths

• 1700 km of 24-channel seismic reflection data provides detailed subsurface imaging.
• 2550 km of bathymetric, gravity, and magnetic data offers multi-modal geophysical coverage.
• 31 bottom samples with detailed core analyses provide direct geological and paleoenvironmental evidence.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic and temporal bias inherent to a single 1977 survey campaign.
• Row count is unknown, which may limit suitability assessment for large-scale statistical modeling.
