  • The Early Permian to Middle Triassic Bowen and Gunnedah Basins and the Early Jurassic to Early Cretaceous Surat Basin exhibit a complex subsidence history over a period of about two hundred million years. Backstripped tectonic subsidence curves, constructed by removing the effects of processes such as sediment loading, loading due to the water column, and sediment compaction allow the subsidence histories of the basin to be examined in terms of the tectonic drivers that caused the subsidence of the basins. In the Early Permian, rapid subsidence was driven by mechanical extension, forming a series of half grabens along the western margin of the Bowen and Gunnedah Basins. Mechanical extension ceased at about 280 Ma, being replaced by a phase of passive thermal subsidence, resulting in more widespread, uniform sedimentation, with reduced tectonic subsidence rates. At the start of the Late Permian, the passive thermal subsidence phase was interrupted by the onset of lithospheric flexure during a foreland basin phase, driven by convergence and thrust loading to the east in the New England Orogen. Initially, dynamic loading, caused by viscous corner flow in the asthenospheric wedge above the west-dipping subducting plate, led to limited tectonic subsidence. Later in the Late Permian, the dynamic loading was overwhelmed by static loading, caused by the developing retroforeland thrust belt in New England, leading to very high rates of tectonic subsidence, and the development of a major retroforeland basin. Peneplanation in the Late Triassic was followed by sedimentation at the start of the Jurassic, forming the Surat Basin, where the tectonic subsidence can again be interpreted in terms of dynamically-induced platform tilting. Subduction ceased at about 95 Ma, resulting in rapid uplift, due the rebound of the lithosphere following cessation of subduction, or it stepping well to the outboard of Australia.

  • The Collaborative East Antarctic Marine Census (CEAMARC) voyage was conducted on the Aurora Australis between December 2007 and January 2008. The voyage was operated as part of the Census of Antarctic Marine Life (CAML) program to document the benthic communities and their associated habitats across the George V Shelf in east Antarctica. Underwater video footage was collected from 22 sites across the shelf using Geoscience Australia's Deep Under Water Camera (DUCII). Transects were run for 15-40 minutes across depths ranging from 140 m to 1200 m. All video footage is stamped with the UTC time. Stations are named according to the CEAMARC station number followed by the instrument used (eg. CAM for camera) and then the deployment number. For example 09CAM05 was deployed at CEAMARC site 9 and was the 5th camera transect. The location and depth of each station is listed below.

  • This dataset reflects the external boundaries of all native title determination and compensation applications that are currently recognized and active within the Federal Court process. Applications that are non-active (i.e. withdrawn, dismissed, finalised, rejected or combined) are only included as aspatial records for completeness. This is a national dataset with data partitioned by jurisdiction (State), for ease of use. Applications stored for each jurisdiction dataset include applications which overlap into adjoining jurisdictions as well as applications which overlap with these for completeness. This dataset depicts the spatial definition of active Claimant and Non-claimant native title determination applications and compensation applications. Where possible these may include internal boundaries or areas excluded. Aspatial attribution includes National Native Title Tribunal number, Federal Court number, application status and the names of both the NNTT Case Manager and Lead Member where assigned to the application. Applications included on the Schedule of Native Title (Federal Court) include all registered and unregistered applications as well as determined applications that are yet to be finalized.
