Geoscience Australia collected underwater video and still images from 49 stations in the Browse Basin's Leveque Shelf during a May 2013 marine survey. The survey aimed to assess CO2 storage potential by looking for gas seepage and mapping seabed habitats. Data includes video files, still images, and USBL navigation files providing location, time, and depth information.
Use Cases
- Detect evidence of past or present gas seepage based on seabed video footage.
- Map seabed habitats and biota associated with seepage features mentioned in the description.
- Assess geological structures like faults for CO2 containment potential based on survey aims.
- Correlate navigational data with video transects for spatial analysis of seabed features.
Strengths
- Video collected from 49 distinct stations.
- Includes real-time onboard video characterizations using the AIMS-TowedVid classification system.
- Provides continuous navigational information (USBL) with location, time, and depth for each transect.
Limitations
- Video quality varies between sites, as noted in the description.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
