Multi-channel seismic reflection, wide-angle seismic refraction, bathymetry, gravity, and magnetic data acquired onboard the JAMSTEC vessel R/V Kairei in March–May 2016. The data collection includes a 680 km east-west profile and ~600 km of high-resolution 2D seismic data, presented by the Australian Ocean Data Network. Preliminary results were presented at the 2016 Seismological Society of Japan Fall Meeting.
Use Cases
- Model crustal thickness and composition based on wide-angle seismic refraction data and Moho reflections.
- Interpret rift-fill sedimentary deposits and acoustic basement structure using multi-channel seismic reflection profiles.
- Analyze the transition from oceanic to continental crust across basins and platforms using combined seismic datasets.
- Support site selection for deep-sea drilling proposals based on high-resolution 2D seismic data.
Strengths
- Includes a 680 km long east-west seismic profile with conjoint wide-angle refraction and multi-channel reflection data.
- Contains ~600 km of high-resolution 2D seismic reflection data at seven potential IODP drilling sites.
- Data acquisition involved ~100 ocean-bottom seismometers (OBS) recording clear arrivals at offsets up to 250 km.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data formats are PDF and HTML, suggesting the dataset may consist of reports and presentations rather than raw numerical data.
