49 stations of underwater video footage and still images were collected by Geoscience Australia in May 2013 on the Leveque Shelf, Northwest Shelf, Western Australia. The survey aimed to identify evidence of gas or fluid seepage and map seabed habitats to assess the CO2 storage potential of the Browse Basin. Data includes AVI video files, still images, and USBL navigation files providing location, time, and depth.
Use Cases
- Detect past or current gas seepage based on underwater video footage from 49 stations
- Map seabed habitats and biota associated with geological seepage features
- Assess CO2 containment potential based on seabed and shallow geological information
- Correlate seabed features with subsurface faults using continuous USBL navigation data
Strengths
- Video footage from 49 distinct stations provides multiple observation points
- Includes continuous navigational data (USBL) with location, time, and depth for each transect
- Survey was conducted under a national government plan (NCIP) for a specific scientific aim
Limitations
- Video quality varies between sites, which may affect analysis consistency
- Row count and column-level documentation are unknown, limiting suitability assessment
- Data may reflect geographic bias inherent to the specific survey area
