Torres Strait Marine Biophysical Survey Data and Analysis

Geoscience Australia survey 273 results characterize northwest Torres Strait marine processes during trade wind conditions. The report compares these findings with prior monsoon season data from survey 266, addressing objectives of the Torres Strait CRC program. Data was published by the Australian Ocean Data Network.

Use Cases

• Compare seabed conditions from multibeam sonar and grab sample data between monsoon and trade wind seasons.
• Analyze hydrodynamic patterns using current meter and Bureau of Meteorology meteorological data.
• Characterize mobile sediments and seabed composition from vibro-core and underwater video records.
• Integrate Landsat imagery with in-situ survey data for regional seabed mapping.

Strengths

• Includes data from two distinct seasonal surveys (monsoon and trade wind conditions).
• Combines multiple data types: multibeam sonar, current meters, grab samples, vibro-cores, video, meteorological data, and satellite imagery.

Limitations

• Primary data is embedded within a PDF/HTML report, requiring extraction for computational analysis.
• Sample sizes, row counts, and specific data ranges for each instrument are not provided.

Provenance

Collection Method

Field survey (survey 273) acquiring multibeam sonar, current meters, grab samples, vibro-cores, underwater video, supplemented by meteorological data and Landsat imagery.

Time Range

Surveys covered monsoon season (survey 266) and trade wind season (survey 273).

Freshness

Last updated in April 2026, but underlying survey data is from earlier research programs.
