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

A 2015 marine survey conducted by Geoscience Australia from April 5th to 24th acquired high-resolution bathymetry data over the Gippsland Basin. The survey aimed to collect precompetitive 2D seismic and sub-bottom profiling data to assess the basin's CO2 storage potential and identify indicators of compromised seal integrity. The bathymetry data from this survey is available for free download from the Geoscience Australia website.

Use Cases

• Assessing CO2 storage reservoir potential based on high-resolution bathymetry data.
• Identifying and characterizing natural hydrocarbon or fluid seepage indicators to evaluate seal integrity.
• Enhancing sequence stratigraphic studies of the Gippsland Basin using detailed seafloor mapping.
• Supporting marine spatial planning and geological hazard assessment with bathymetric grids.

Strengths

• Data collected during a dedicated 20-day marine survey in April 2015.
• Industry-standard precompetitive data including Multi-beam echo-sounder (MBES) and sub-bottom profiling (SBP).
• Explicitly collected to support the National CO2 Infrastructure Plan (NCIP).

Limitations

• Row count and specific column-level documentation are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
• Data may reflect geographic and temporal bias inherent to the specific 2015 survey period.
