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

1700 km of 24-channel seismic data and 2550 km of bathymetric, gravity, and magnetic data were recorded during a 1977 R.V. Valdivia survey between the Scott Plateau and Java Trench. The dataset includes 31 bottom samples from water depths between 2000 m and 5800 m, providing information on sediment layers and tectonic structures. It was aggregated by the Australian Ocean Data Network.

Use Cases

• Modeling tectonic plate interactions based on seismic profiles and fault descriptions.
• Analyzing deep-sea sedimentation rates and calcite compensation depth changes based on core sample data.
• Mapping bathymetric features like canyons, abyssal plains, and plateaus for geological interpretation.
• Studying the composition and economic potential of seabed resources based on manganese nodule content analysis.

Strengths

• Data collection includes multiple complementary geophysical measurements (seismic, bathymetry, gravity, magnetics).
• 31 physical bottom samples provide ground-truth data for interpreting seismic sequences.
• Spatial coverage spans a significant transect from a continental block to an oceanic trench.

Limitations

• Data is from a single survey in 1977; temporal coverage is limited to that point in time.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
