Multichannel Seismic Reflection Data from RV Investigator Voyage IN2020_V01

Nine seismic reflection profiles collected aboard the RV Investigator between 10 January and 6 March 2020. The dataset, provided in SEG-Y format, supports investigations of crustal structure and tectonic evolution across the William's Ridge and Broken Ridge regions of the southern Kerguelen Plateau. Data is spatially referenced with UTM coordinates and Common Depth Point numbering.

Use Cases

• Model upper crustal structure based on seismic profiles of William's Ridge
• Analyze tectonic evolution based on seismic reflection data from the Kerguelen Plateau region
• Investigate magmatic evolution based on seismic imaging of hotspot-related features
• Support Extended Continental Shelf investigations based on geophysical survey data

Strengths

• Data is provided in SEG-Y format, the industry standard for seismic reflection data
• Nine distinct seismic profiles were collected, imaging both William's Ridge and Broken Ridge
• Spatial referencing is provided with UTM Easting and Northing coordinates

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
