In February-March 2004, Geoscience Australia undertook a 26 day geophysical and geological survey of the undrilled frontier depocentres of the Bremer and Denmark sub-basins. These sub-basins comprise the western part of the Bight Basin, and are located off the southern coast of Western Australia in water depths ranging from 100 to 4500 m. The survey was planned to recover rock samples and acquire high-speed seismic and swath data over the sub-basins in order to define a chronostratigraphic and depositional framework for the evolution of these depocentres. Ultimately, this information will be used to advance our understanding of the petroleum prospectivity of this frontier region.
