GA-0352: High-Resolution Bathymetry Grids from the 2015 Gippsland Marine Seismic Survey

Geoscience Australia conducted the GA-0352 marine seismic survey in the Gippsland Basin from April 5 to 24, 2015. The survey collected industry-standard precompetitive 2D seismic, multi-beam echo-sounder, and sub-bottom profiling data to assess the basin's CO2 storage potential. This dataset includes all bathymetry data from that survey, available for free download.

Use Cases

• Assessing CO2 storage reservoir potential based on seismic and bathymetry data mentioned in the description
• Identifying indicators of natural fluid seepage to evaluate seal integrity as described for the Gippsland Basin
• Enhancing sequence stratigraphic studies using the high-resolution bathymetry grids collected during the survey
• Supporting the National CO2 Infrastructure Plan (NCIP) by providing precompetitive data for basin characterization

Strengths

• Data collected over a defined 20-day period from April 5 to 24, 2015
• Includes multiple data types: 2D seismic, multi-beam echo-sounder (MBES), and sub-bottom profiling (SBP)
• Survey conducted by a specific vessel, the Gardline CGG MV Duke
• Data is available for free download from the Geoscience Australia website

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count and dataset size are unknown, which may limit suitability assessment
