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

Interpretation of seismic refraction data from the southwestern coast of the Papuan Peninsula and the northwest Coral Sea. The dataset includes sediment thicknesses of 1 to 10 km, P-wave velocities of 6.07 km s^-1 and 6.9 km s^-1, and Moho depths ranging from 19 to 29 km. It was published by Geoscience Australia Data.

Use Cases

• Model tectonic evolution based on inferred crustal layers and Moho depths.
• Analyze sediment distribution based on thickness measurements from 1 to 10 km.
• Study crustal thinning and continental vs. oceanic crust boundaries based on described structural interpretations.

Strengths

• Includes specific quantitative measurements like sediment thickness (1-10 km) and P-wave velocities (6.07, 6.9 km s^-1).
• Results are described as consistent across several inversion techniques.
• Provides Moho depth measurements ranging from 19 to 29 km.

Limitations

• Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
• Row count and column-level documentation are unknown.
• The description notes insufficient data to confirm certain lower crustal features offshore.
