Seabed Environments of the Eastern Joseph Bonaparte Gulf, Northern Australia

A seabed mapping survey over carbonate banks, channels, and sediment plains on the Van Diemen Rise collected detailed geological and biological data. The survey includes 1,154 square kilometres of multibeam sonar data and 340 line-km of sub-bottom profiles, supplemented by samples from 63 stations. It was conducted by Geoscience Australia and the Australian Institute of Marine Sciences to investigate the region's late-Quaternary evolution and biodiversity.

Use Cases

• Modeling late-Quaternary seabed evolution based on geological and geophysical data.
• Investigating relationships between physical environment and benthic community structure.
• Conducting biogeographic analysis of benthos within the wider northern Australian marine region.
• Assessing sediment and water quality for surrogacy research using geochemical data.
• Understanding sediment transport dynamics from collected oceanographic data on waves, tides, and currents.

Strengths

• Multibeam sonar data provides 100% seabed coverage for four study areas.
• Dataset integrates geological, biological, geochemical, and oceanographic data from 63 sampling stations.
• Includes 1,154 square kilometres of multibeam sonar data and 340 line-km of sub-bottom profiles.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey area in the Joseph Bonaparte Gulf.
