71 line kilometers of high and low frequency sidescan sonar data collected by an Autonomous Underwater Vehicle (AUV) during a 2014 marine survey. Geoscience Australia conducted the survey (GA0346) aboard the RV Tangaroa to assess the CO2 storage potential of the Caswell Sub-basin. The data includes high-frequency (390-430 kHz) and low-frequency (98-111 kHz) sonar readings.
Use Cases
- Analyzing seabed texture and features for signs of fluid seepage based on sidescan sonar imagery.
- Mapping geological structures to evaluate seal integrity for CO2 storage based on survey objectives.
- Integrating sonar data with multibeam bathymetry and sub-bottom profiles for comprehensive seabed characterization.
Strengths
- Data covers a specific, high-resolution survey area of 7.7 km² collected by an AUV.
- Includes dual-frequency sonar data (high: 390-430 kHz, low: 98-111 kHz) with detailed acquisition parameters.
- Part of a larger integrated survey that also collected multibeam sonar, seabed samples, and underwater video.
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/temporal bias inherent to the specific 2014 survey.
