Kenn Plateau Geology: Seismic and Bathymetric Survey Data Off Northeast Australia

The Kenn Plateau off northeast Australia is the subject of this marine geological survey. The dataset includes 3090 km of high-quality seismic data and 7584 km of bathymetric data collected by the RV Southern Surveyor, with a limited sampling program of 12 dredge hauls and one grab. The data was contributed by the Australian Ocean Data Network to improve understanding of this poorly known part of Australia's marine jurisdiction.

Use Cases

• Modeling geological evolution based on seismic reflection profiles mentioned in the description.
• Improving bathymetric maps and analyzing seafloor morphology using the swath-mapping data.
• Reconstructing regional geological history based on the recovered rock samples.

Strengths

• Includes 3090 km of high-quality seismic data.
• Contains 7584 km of bathymetric data collected with a SIMRAD EM 300 multibeam sonar system.
• Represents the first recovery of ancient rocks from this frontier offshore region.

Limitations

• The physical sampling program was greatly curtailed, resulting in only 12 dredge hauls and one grab sample.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
