Marine Geophysical Survey Data from Scott Plateau to Java Trench, 1977

Geoscience Australia Data provides a 1977 marine survey dataset from the R.V. Valdivia. The collection includes 1700 km of 24-channel seismic data, 2550 km of bathymetric, gravity, and magnetic data, and 31 bottom samples from water depths of 2000 m to 5800 m. The data covers the Scott Plateau, Argo Abyssal Plain, Roti Basin, and Java Trench off northwest Australia.

Use Cases

• Modeling tectonic plate boundaries and transform faults based on seismic profiles and bathymetric features.
• Analyzing sedimentation history and calcite compensation depth changes based on core sample data.
• Mapping seafloor morphology and basement structure using bathymetric, gravity, and magnetic survey lines.
• Investigating continental breakup and rift evolution during the Late Jurassic based on described seismic sequences and fault patterns.

Strengths

• Includes 1700 km of 24-channel seismic reflection data.
• Contains 2550 km of co-located bathymetric, gravity, and magnetic survey data.
• Provides 31 physical bottom samples with detailed depth and location context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single 1977 survey; temporal coverage is limited.
