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

Geoscience Australia collected marine geophysical data from the Kenn Plateau off northeast Australia. The survey gathered 3090 km of seismic data and 7584 km of bathymetric data, along with 12 dredge hauls and one grab sample. The data was collected during a research voyage on the RV Southern Surveyor, with an additional two days of ship time scheduled for November-December 2004.

Use Cases

• Improving geological models based on the 3090 km of high-quality seismic data.
• Enhancing bathymetric maps and studying sedimentary processes using the 7584 km of swath-mapping data.
• Reconstructing regional geological history based on the recovered rock samples from dredge hauls.

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

• Sampling program was 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.
