Gippsland Basin High Resolution Bathymetry Grids From 2015 Survey

Geoscience Australia's 2015 marine survey (GA-0352) acquired high-resolution bathymetry data to assess CO2 storage potential in the Gippsland Basin. The survey, conducted from April 5th to 24th, 2015, by the vessel MV Duke, collected industry-standard Multi-beam echo-sounder (MBES) and sub-bottom profiling (SBP) data. This precompetitive data supports sequence stratigraphic studies and identification of potential CO2 storage reservoirs.

Use Cases

• Analyze high-resolution bathymetry grids to model seafloor morphology for CO2 storage site suitability assessments.
• Integrate Multi-beam echo-sounder (MBES) data with sub-bottom profiling (SBP) data to characterize subsurface seal integrity.
• Use the bathymetry data to constrain sequence stratigraphic models of the Gippsland Basin for geological studies.
• Identify and map indicators of natural fluid seepage from the survey data to evaluate regional seal integrity.

Strengths

• Data collected using industry-standard acquisition methods (MBES and SBP) ensuring technical reliability.
• Focused temporal coverage from a dedicated 20-day survey in April 2015 providing a consistent snapshot.
• Precompetitive data specifically aimed at supporting the assessment of CO2 storage potential.

Limitations

• Dataset is explicitly not to be used for navigational purposes, limiting its application scope.
• Lack of available metadata on column structure, sample data, or file sizes hinders initial technical assessment.
• Primary focus on a specific basin (Gippsland) and purpose (CO2 storage) may limit generalizability for other marine studies.
