140,000 km² of seabed was mapped during a 25-day survey in January/February 2000 by the Australian Geological Survey Organisation (AGSO). The cruise collected swath bathymetry, seismic, sub-bottom profiling, gravity, magnetic, and oceanographic data to support continental shelf definition and marine resource assessment. Data quality was generally excellent despite occasional rough weather.
Use Cases
- Mapping foot-of-slope positions based on swath bathymetry data to support legal continental shelf definition.
- Assessing seabed living and non-living resources based on geophysical and oceanographic profiles.
- Analyzing seafloor tectonic features like seamounts and ridges based on the described survey highlights.
Strengths
- Survey mapped approximately 140,000 km² of seabed.
- Data collection included multiple geophysical and oceanographic instruments.
- Weather conditions were highly favourable, contributing to excellent data quality.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Data freshness should be verified; the last metadata update is 2026-05-05.
- Row count is unknown, which may limit suitability assessment.
