Gippsland Basin High-Resolution Bathymetry Grids From 2015 Survey

High-resolution bathymetry grids were collected during a 2015 marine seismic survey (GA-0352) conducted by Geoscience Australia from April 5th to April 24th. The survey aimed to acquire industry-standard precompetitive 2D seismic, multi-beam echo-sounder, and sub-bottom profiling data to assess the CO2 storage potential of the Gippsland Basin. Data are managed by the Australian Ocean Data Network and were last updated in April 2026.

Use Cases

• Assess CO2 storage reservoir suitability by analyzing bathymetry grids and sub-bottom profiles for seal integrity indicators.
• Conduct sequence stratigraphic studies using high-resolution bathymetry data to constrain suitable areas within the Gippsland Basin.
• Identify potential fluid seepage features that may indicate compromised seal integrity from the marine seismic and multi-beam echo-sounder data.
• Support the National CO2 Infrastructure Plan by providing precompetitive geophysical data for basin-scale storage potential evaluation.

Strengths

• Data collected over a 19-day survey period in April 2015 providing a focused temporal snapshot.
• Includes multiple geophysical data types: 2D seismic, multi-beam echo-sounder bathymetry, and sub-bottom profiling.

Limitations

• Specific row counts, column details, and spatial resolution of the bathymetry grids are unknown.
• Data is from a single survey in 2015 and may not reflect current seabed conditions.
