Ngalia Basin hydrogeological inventory

This Ngalia Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus.
The Ngalia Basin is an elongate, east-trending basin over 500 km long and 90 km wide. It occurs mostly in the Northern Territory, with limited occurrence in Western Australia. The Ngalia Basin is an intra-cratonic sedimentary basin in a structural downwarp formed by a faulted asymmetrical syncline. The basin began to form about 850 Ma, and contains a Neoproterozoic to Carboniferous sedimentary succession. Sedimentation ceased in response to the 450 to 300 Ma Alice Springs Orogeny.
The maximum stratigraphic thickness of the Ngalia Basin is about 5000 m. The basin contains mainly arenaceous sedimentary rocks, with lesser fine-grained rock types and some carbonates. Fining upwards sedimentary cycles are commonly preserved and capped by calcite-cemented fine-grained sandstone and siltstone. Tectonic events disrupted deposition during basin evolution and led to at least ten unconformities. There are many disconformable contacts, with angular unconformities common in areas with abundant faulting.
The upper-most arkosic sandstone formations in the Ngalia Basin are the Mount Eclipse Sandstone and the Kerridy Sandstone. These units have an aggregate thickness of several hundreds of metres and are the main aquifers within the Ngalia Basin sequence. There is some interstitial porosity, especially in the Mount Eclipse Sandstone, although joints and fissures associated with faulting provide significant secondary permeability. These aquifers provide good supplies of potable to brackish groundwater, and supply the community borefield at Yuendumu. 
The Ngalia Basin is almost entirely concealed by Cenozoic cover, including Palaeogene-Neogene palaeovalley, lake and alluvial fan sediment systems and Quaternary aeolian sands. Shallow aquifers with brackish to potable water occur in many palaeovalleys sediments overlying the basin.

GSWA Eucla Basin 4 Madura TMI Grid Geodetic

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.
This GSWA Eucla Basin 4 Madura TMI Grid Geodetic has a cell size of 0.00042 degrees (approximately 43m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2010 by the WA Government, and consisted of 103672 line-kilometres of data at 200m line spacing and 50m terrain clearance.

Lord Howe Island infaunal diversity

Geoscience Australia carried out a marine survey on Lord Howe Island shelf (NSW) in 2008 (SS06_2008) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments and infauna, rock coring, observation of benthic habitats using underwater towed video, and measurement of ocean tides and wave generated currents. Subbottom profile data was also collected to map sediment thickness and shelf stratigraphy. Data and samples were acquired using the National Facility Research Vessel Southern Surveyor. Bathymetric data from this survey was merged with other preexisting bathymetric data (including LADS) to generate a grid covering 1034 sq km. As part of a separate Geoscience Australia survey in 2007 (TAN0713), an oceanographic mooring was deployed on the northern edge of Lord Howe Island shelf. The mooring was recovered during the 2008 survey following a 6 month deployment.

Building Survey in the Brisbane Central Business District (CBD) - Flyer

Knowledge of the nature of buildings within CBD areas is fundamental to a broad range of decision making processes, including planning, emergency management and the mitigation of the impact of natural hazards. To support these activities, Geoscience Australia has developed a building information system called the National Exposure Information System (NEXIS) which provides information on buildings across Australia. Most of the building level information in NEXIS is statistically derived, but efforts are being made to include more detailed information on the nature of individual buildings, particularly in CBD areas. This is being achieved in Brisbane through field survey work.

The Stratigraphic and Tectonic development of the Manokwari Area, Irian Jaya

The Manokwari area lies in the northeastern extremity of the Kepala Burung region in the western part of Irian Jaya. In 1976 the area was investigated at the start of an ongoing mapping programme which will be carried out as an Indonesian-Australian integrated geological survey of Irian Jaya. Ten mappable units have been recognised in the area, ranging in age from Silurian to Holocene. The Silurian to Devonian metamorphics crop out in the southern mountainous region, and consist mainly of fine-grained low-grade regionally metamorphosed sedimentary rocks. Along the length of the mountain front these rocks have been intruded and partially assimilated in places by a number of late Permian to middle Triassic granodiorite bodies and a middle Miocene diorite body. Basalt and andesite flow breccia, tuff, and volcaniclastic sediments occur to the southeast, and are probably Oligocene to Miocene in age. Massive algal-foraminiferal biomicrite of Miocene age forms a number of elongate ridges to the northeast of the volcanics and probably unconformably overlies them. In the northeastern part of the area soft, well-bedded mudstone, siltstone and sandstone of late Miocene to Pleistocene age is unconformably overlain by Pleistocene raised reefs. Surrounded by the western part of the extensive alluvial plain is a symmetrical mountain of ?Pliocene agglomerate. Immediately to the south, at the edge of the mountain front is an area of uplifted, dissected, and northerly-tilted coarse alluvium and fanglomerate. The Manokwari area is situated amid a complex array of crustal plates and sub-plates which formed as a result of complicated interaction between the Australian and Pacific Plates and the island arcs and ocean basins of the Indonesian Archipelago. The two major structural elements within the Manokwari Sheet, the Sorong and Ransiki Fault Zones, are continent-island arc collision sutures which have subsequently undergone sinistral transcurrent faulting.

A Software Tool for Assessing Transmission Line Vulnerability Based on a Monte Carlo Simulation

Severe wind hazard poses a great risk to high voltage transmission lines consisting of various types of towers such as suspension, tension, and terminal towers. Geoscience Australia (GA) has developed a software called WISTL (Wind Impact Simulation on Transmission Lines) based on a Monte Carlo simulation to assess the damage likelihood to transmission lines. It simulates two different damage mechanisms: damage due to direct wind assuming towers are isolated, and cascading failure mechanism where damage is induced by the collapse of adjacent towers. It produces a damage probability for each damage state by tower and probability distribution of number of damaged towers by line.

Murray-Darling Basin Vegetation Monitoring Project Final Report

This project commenced in November 2012 and is intended to provide satellite data and related scientific services to support the Murray-Darling Basin Authority's monitoring of how the condition of riparian vegetation responds to changing river run-off and wetland inundation levels. 
Under this project, Geoscience Australia started to build a satellite data processing infrastructure; named the 'datacube', as a proof of concept for expected on-going time series analysis applications including historical flood and bathymetry mapping.
The work incorporates an automated processing chain for Landsat satellite images from Geoscience Australia's extensive archive, into customised high level intermediate products, including automated ortho-rectification, atmospheric correction, cloud-removal, and mosaicking, and finally into statistics on the spectral and derivative indices (that is, vegetation condition indices or various types) for the summer periods of December-March, each year for the period 2000-2013. 
These vegetation indices and associate statistics are then used, by the Murray-Darling Basin Authority and its collaborators, as inputs to a mathematical model of vegetation types and their respective conditions within the Murray-Darling Basin.
