49 stations of underwater video and still images were collected by Geoscience Australia in May 2013 on the Leveque Shelf, a sub-basin of the Browse Basin off Western Australia. The survey aimed to identify evidence of past or current gas seepage and map seabed habitats to support an assessment of the basin's CO2 storage potential. Data includes AVI video files, onboard video characterizations, still images, and USBL navigation files providing location, time, and depth for each transect.
Use Cases
- Identify seabed features related to potential gas or fluid seepage based on underwater video transects.
- Map seabed habitats and biota communities mentioned in the survey description.
- Correlate seabed observations with underlying geological structures like faults using navigational data.
- Assess the integrity of potential CO2 storage seals by analyzing seabed evidence of past fluid migration.
Strengths
- Data was collected from 49 distinct stations, providing multiple observation points.
- Includes multiple data modalities: video files, real-time onboard characterizations, still images, and continuous USBL navigation logs.
- Survey was conducted under the Australian Government's National CO2 Infrastructure Plan with a clear scientific aim.
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 and dataset size are unknown, which may limit suitability assessment.
