AUV Sidescan Sonar Data from 2014 Browse Basin Marine Survey

71 line kilometers of high and low frequency sidescan sonar data were collected by an Autonomous Underwater Vehicle (AUV) during the GA0346 survey leg in October-November 2014. Geoscience Australia conducted the survey to assess the CO2 storage potential of the Caswell Sub-basin in the Browse Basin. The data aims to identify indicators of natural fluid seepage that may compromise geological seal integrity.

Use Cases

• Identify seabed features indicative of fluid seepage based on sidescan sonar imagery.
• Characterize geological seal integrity for CO2 storage assessment based on survey objectives.
• Map high-resolution seabed morphology in water depths of 90-430 meters based on the survey area.

Strengths

• Data includes 71 line kilometers of sidescan sonar coverage.
• Specified collection parameters for both high (390-430 kHz) and low (98-111 kHz) frequency systems.
• Survey conducted by a national geological authority (Geoscience Australia) with multi-institutional collaboration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and exact file sizes are unknown, which may limit suitability assessment.
