Lagrange-Munro, WA, 2010 (North Canning 4) (P1230), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Lagrange-Munro, WA, 2010 (North Canning 4) survey were acquired in 2010 by the WA Government, and consisted of 103921 line-kilometres of data at 400m line spacing and 60m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Hydrocarbon and Geothermal Prospectivity of Sedimentary Basins in Central Australia; Warburton, Cooper, Pedirka, Galilee, Simpson and Eromanga Basins

Within the Central Australian region, nominally constrained by 22.5oS 134oE and 31.5oS 144oE for this study, lie several systems of stacked basins beneath the extensive Mesozoic Eromanga Basin.  Remnants of Proterozoic basins are largely inferred from gravity, unexplored, and are not everywhere differentiated from an extensive cover of the lower Palaeozoic Warburton Formation.  This sequence is the central link between the contiguous Amadeus, Officer and Georgina Basins, and the Thomson Fold Belt. 
Since the Carboniferous, the region has largely experienced intracratonic sag and has accumulated continental sediments, including thick coal measures, with intermittent tectonism and uplift. In late Early Cretaceous, marine conditions briefly invaded this subsiding region, but continental sedimentation resumed in the Late Cretaceous. Tectonism occurred in the Tertiary with basin inversion and subsequent formation of the Great Artesian Basin. In the Cainozoic, the region is again in subsidence and accommodating fluvial and aeolian sediment slowly into the Eyre Basin. The preserved depocentres of the Carboniferous-Permian-Triassic Cooper, Pedirka-Simpson, and Galilee Basins are spatially separate, although all contain comparable, largely organically-mature continental coal measure sequences.

Seafloor environments of the eastern Timor Sea, Northern Australia: Total organic carbon (TOC), Total nitrogen (TN) and organic carbon and nitrogen isotopes of seabed sediments.

The Timor Sea and its tropical marine environment support significant and growing economic activity including oil and gas exploration. To reduce uncertainty in decision making regarding the sustainable use and ongoing protection of these marine resources, environmental managers and resource users require sound scientific information on the composition and stability of seabed environments and their biological assemblages. Surveys SOL4934 and SOL5117 to the eastern Joseph Bonaparte Gulf were undertaken in August and September 2009 and July and August 2010 respectively, in collaboration with the Australian Institute of Marine Science, with research collaborations from the RAN Australian Hydrographic Office, the Geological Survey of Canada and the Museum and Art Gallery of the Northern Territory. The purpose of these surveys were to develop biophysical maps, and deliver data and information products pertaining to complex seabed environment of the Van Diemen Rise and identify potential geohazards and unique, sensitive environments that relate to offshore infrastructure. This dataset comprises total organic carbon (TOC), Total nitrogen (TN) and organic carbon and nitrogen isotopes on the upper 2cm of seabed sediments.

Redlichia of the Ordian (Cambrian) of Northern Australia and New South Wales

The systematic part of this paper is the continuation of my study (bpik, 1958) of the anatomy and concept of the genus Redlichia, presented on the basis of Redlichia forresti from the Negri Group of Western Australia, Redlichia idonea from the Yelvertoft Beds of Queensland, and some other, then unnamed, species. At that time (op. cit., p. 36) the taxonomy of the species was reserved for the future. This paper serves a double purpose-first, in presenting such speciestaxa as can be established from selected and properly preserved material, and second, in establishing a sequence of informal 'biostratigraphic operational units' in advance of a scale of Ordian zones. Such a scale of zones would be premature in view of the difference between the specific composition of Redlichia in Queensland and in the Northern Territory, and because of the incompleteness of data regarding the vertical distribution and specific taxonomy of Redlichia in many sites of the Territory, and the numerous undescribed other fossils of the Ordian of Australia. The fossils are kept in the Museum of the Bureau of Mineral Resources and the specimen numbers (CPC) refer to the Commonwealth Palaeontological (type) Collection.

DEPRECATED - High tide and low tide composites 25m v. 2.0.0

This record has been superseded by eCat 150381
The High and Low Tide Composites product is composed of two surface reflectance composite mosaics of Landsat TM and ETM+ (Landsat 5 and Landsat 7 respectively) and OLI (Landsat 8) surface reflectance data (Li et al., 2012). These products have been produced using Digital Earth Australia (DEA). The two mosaics allow cloud free and noise reduced visualisation of the shallow water and inter-tidal coastal regions of Australia, as observed at high and low tide respectively (Sagar et al., 2018).
The composites are generated utilising the geomedian approach of Roberts et al (2017) to ensure a valid surface reflectance spectra suitable for uses such as habitat mapping. The time range used for composite generation in each polygon of the mosaic is tailored to ensure dynamic coastal features are captured whilst still allowing a clean and cloud free composite to be generated. The concepts of the Observed Tidal Range (OTR), and Highest and Lowest Observed Tide (HOT, LOT) are discussed and described fully in Sagar et al. (2017) and the product description for the ITEM v 1.0 product (Geoscience Australia, 2016).
