Southern Surveyor Cruise SS5/2004 collected 3090 km of multichannel seismic data and continuous multibeam-sonar bathymetry over the Kenn Plateau. The survey recovered twelve dredge hauls of sedimentary rocks, many dated as Eocene and younger, revealing a highly complex plateau with basement ridges and Oligocene volcanoes. The dataset, managed by the Australian Ocean Data Network, documents about 140,000 km sq of thinned continental crust.
Use Cases
- Modeling crustal thinning and subsidence based on seismic sequences and magnetic data
- Analyzing tectonic rotation and fault displacement based on described fracture zones and anticlines
- Studying volcanic hotspot chain formation based on Oligocene Tasmantid chain edifices
- Mapping sediment deposition patterns based on described Cretaceous to Recent sequences
Strengths
- Includes 3090 km of multichannel seismic data
- Continuous multibeam-sonar swath-bathymetry coverage
- Twelve dredge hauls with micropaleontologically dated samples
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
