Title: Bremer Sub-basin 3D VRML Model


Custodian: Geoscience Australia

Jurisdiction: Australia




In May 2003, the Australian Government provided $A25 million to fund a four year New Oil program aimed at developing new exploration opportunities in offshore Australia, through an integrated program of seismic acquisition, geological sampling, and seep detection in key frontier basins. This VRML of the Bremer Sub-basin was created as an output of the Bremer Sub-basin Study within the New Oil program (Geoscience Australia Record 2005/21). It provides a 3D visual compilation of key interpretations within the sub-basin, and also some of the key data sets used.

Key interpretations and data include:

Basement surface,

Gridded Bathymetry,

Locations of seismic data and large scale JPEG images,

Locations of dredge sites and dredge information.

This tool is ideal for those interested in quickly understanding the geometry and structural architecture of the Bremer Sub-basin, as well as a quick look at the seismic interpretations and dredge analyses carried out during the study.

The results of the Bremer Sub-basin study have been published in Geoscience Australia Record 2005/21 (Geology and Petroleum Potential of the Bremer Sub-basin, Offshore Southwestern Australia) which is available from the Geoscience Australia Sales Centre.

More information on the Bremer Sub-basin is available on the Southern Australian Frontiers.


This VRML model contains fault and horizon interpretations, images of seismic data, geological dredge data and high-resolution swath bathymetry of the Bremer Sub-basin study area.

Geographic extent:

The Bremer Sub-basin is located off the south coast of Western Australia, adjacent to the coastal towns of Albany, Bremer Bay and Esperance.

This translation has been applied to enhance graphics performance within this model.

Positional accuracy:

Positional accuracy varies with data sources and according to map scale of compilation, therefore it is not possible to predict positional accuracy with confidence.

Attribute accuracy:

Every effort has been made to ensure that features are attributed so that they are fit-for-use, and not necessarily compliant with any data dictionary version such as that constructed by Geoscience Australia. Geological themes sourced from GA data have generally been constructed to comply with an historical version of the GA data dictionary.

Logical Consistency:

The test applied to consistency is fit-for-use, not necessarily compliant with a given standard. Every effort has been made to ensure that themes and layers within themes have been constructed to be logically consistent by following GA standards where these are available.
