Interpretation of seismic refraction data from the southwestern coast of the Papuan Peninsula and the northwest Coral Sea. The dataset includes sediment thicknesses up to 10 km, P-wave velocities, and Moho depths ranging from 19 to 29 km, supporting tectonic models for the region. It was published by the Australian Ocean Data Network and last updated in April 2026.
Use Cases
- Modeling crustal thinning and tectonic evolution based on inferred P-wave velocity layers and Moho depths.
- Mapping sediment thickness distribution for geological resource assessment based on thickness measurements from 1 to 10 km.
- Analyzing regional stress patterns during basin formation based on described tectonic models.
- Comparing continental versus oceanic crust characteristics based on interpretations for the Papuan Peninsula, Eastern Plateau, and Moresby Trough.
Strengths
- Includes specific quantitative measurements, such as sediment thicknesses of 1-2 km, 5 km, and 10 km.
- Provides detailed geophysical parameters, including P-wave velocities of 6.07 km s^-1 and 6.9 km s^-1.
- Defines Moho depths with a range from 19 km to 29 km across different geological features.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
