Crustal Structure of the Gulf of Papua and Northwest Coral Sea from Seismic Data

Interpretation of seismic refraction data from the southwestern coast of the Papuan Peninsula and the northwest Coral Sea. The dataset includes sediment thickness measurements, P-wave velocity layers, and Moho depth estimates, published by Geoscience Australia. The data was last updated on 2026-04-20.

Use Cases

• Modeling tectonic evolution based on inferred continental and oceanic crust boundaries.
• Analyzing sediment thickness distribution across the Papuan Plateau, Moresby Trough, and Eastern Plateau.
• Studying crustal layering and Moho depth variations from seismic velocity data.

Strengths

• Includes specific sediment thickness measurements ranging from 1-2 km to 10 km.
• Provides P-wave velocity values for crustal layers, such as 6.07 km s^-1 and 6.9 km s^-1.
• Contains Moho depth estimates ranging from 19 km to 29 km.

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 the specific seismic survey lines.
