AGSO Cruise 210: Seafloor Swath-Mapping Survey off Eastern Tasmania, 1997

AGSO Cruise 210 collected swath-mapping data of the sea bed east and northeast of Tasmania from 10 to 17 April 1997. The survey used the SeaBeam 2000 multibeam sonar system, a magnetometer, and a gravity meter aboard the R.V. Melville. The data was intended to aid tectonic, basin, and sedimentological studies, as well as the fishing industry.

Use Cases

• Modeling seafloor morphology for tectonic studies based on multibeam sonar data.
• Analyzing sediment distribution patterns based on sea bed character data.
• Planning future seismic profiling or geological sampling campaigns based on the detailed survey tracks.
• Supporting fisheries habitat mapping based on bathymetric and sea bed roughness information.

Strengths

• High-accuracy navigation with military GPS providing about 5-meter precision.
• Multibeam sonar system capable of mapping a swath 3.5 times the water depth.
• Integrated geophysical data collection including bathymetry, magnetics, and gravity.

Limitations

• Data is from a single cruise in April 1997; temporal coverage is limited.
• Row count and specific data formats (PDF, HTML) are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
