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

A 2015 marine survey collected high-resolution bathymetry data in the Gippsland Basin from April 5th to 24th. Geoscience Australia conducted the survey using the vessel MV Duke to support an assessment of the basin's CO2 storage potential. The dataset includes all bathymetry data from the survey, available for free download.

Use Cases

• Modeling seafloor topography for geological studies based on the high-resolution bathymetry grids
• Assessing seal integrity for CO2 storage based on indicators of natural fluid seepage mentioned in the survey aims
• Supporting sequence stratigraphic studies to identify potential CO2 storage reservoirs as described
• Integrating bathymetric data with 2D seismic and sub-bottom profiles for a comprehensive subsurface analysis

Strengths

• Data collected during a dedicated 20-day survey in April 2015, providing a focused temporal snapshot
• Industry-standard precompetitive data acquired, including MBES and SBP alongside seismic
• Data is available for free download from the Geoscience Australia website

Limitations

• Description metadata is limited; actual data quality, resolution, and file structure require manual inspection after download
• Column-level documentation is absent; field semantics and data formats must be inferred from the downloaded files
• The dataset is explicitly not to be used for navigational purposes, limiting its application scope
