Survey 273: Torres Strait Marine Biophysical Processes and Seabed Hydrodynamics

Geoscience Australia survey 273 acquired multibeam sonar, current meters, grab samples, and other data types to characterize mobile sediments and hydrodynamics in northwest Torres Strait. This report compares results from two surveys measuring monsoon and trade wind conditions as part of a CRC research program on seagrass habitats. The data was aggregated by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Modeling sediment transport dynamics based on grab sample and vibro-core data mentioned in the description
• Characterizing seabed morphology and habitats based on multibeam sonar and underwater video data
• Analyzing seasonal hydrodynamic variations based on the comparison of monsoon and trade wind survey results
• Correlating meteorological conditions with marine processes based on Bureau of Meteorology data

Strengths

• Integrates multiple data types including sonar, current meters, samples, video, and satellite imagery for a holistic view
• Compares environmental conditions across two distinct seasonal surveys (monsoon and trade wind)
• Report addresses specific CRC research objectives for understanding biophysical processes

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and dataset scale are unknown, which may limit suitability assessment
• Primary data formats are PDF and HTML, which may require extraction for computational analysis
