Crucial elements for assessing earthquake risk are exposure and vulnerability. In assessing earthquake risk to the Australian built environment we need to know what is exposed to earthquake ground motion and also how vulnerable the exposed infrastructure is to the severity of shaking. While central business district (CBD) buildings make up a relatively small proportion of Australia's built environment their function and the business activity they support is vital to Australia's economy. This paper describes an ongoing effort by the Australian Government to undertake engineering and architectural surveys of buildings within state capital CBDs. With funding from the Attorney-General's Department Geoscience Australia has recently completed a survey of the Melbourne CBD and will complete surveys of the Sydney, Adelaide and Brisbane CBDs this financial year. Survey teams comprise a structural engineer and a GIS operator who populates survey fields on a handheld computer. Approximately 90 survey data fields are incorporated in the template to enable capture of the variety in building features. The fields cover building characteristics that are understood to influence earthquake vulnerability. A summary of the survey activity undertaken to date is presented here along with some examples of the type of data that is being collected.

This is a short and informative 3.3 minute movie for the Engineering, Economics and Exposure Project - NEXIS Development for DCCEE - late 2010. It is a promotional movie that demonstrates NEXIS capabilities, and explains how NEXIS will be benefitial to the NEXIS stakeholder. This movie may also go onto the web, where it's purpose is to convince the public that NEXIS is a worthwhile investment in Australia's future.

This dataset contains species identifications of macro-benthic worms collected during survey SOL4934 (R.V. Solander, 27 August - 24 September, 2009). Animals were collected from the Joseph Bonaparte Gulf with a benthic sled or a Smith-McIntyre grab. Specimens were lodged at Northern Territory Museum on the 24 September 2009. Species-level identifications were undertaken by Chris Glasby at the Northern Territory Museum and were delivered to Geoscience Australia on the 26 October 2009 See GA Record 2010/09 for further details on survey methods and specimen acquisition. Data is presented here exactly as delivered by the taxonomist, and Geoscience Australia is unable to verify the accuracy of the taxonomic identifications.

Report summarises results from the Offshore and Onshore Energy Security Progams undertaken between 2006 and 2011.

The area under review in this report comprises a large territory located in south-western Victoria and south-eastern South Australia. The scope of direct geological information in the areas underlain by marine Tertiary rocks is severely limited, by very poor exposure of the underlying rocks at the surface. Under such conditions, once the scattered exposures have been examined and recorded on the map, little more can be done by surface work; the geologist is thrown back on a study of well and bore records and of the results of geophysical measurements. Considerable literature has been read and records of the principal bores in the area have been examined in detail. It has been recommended that a geophysical survey of the area be conducted, to determine, if possible, any structural features which might exist at depth in this southern-most extension of the Murray River Artesian Basin, which is made up of Tertiary to Recent formations, resting, in the area under review, on a basement of Pre-Cambrian or Jurassic Rocks. This report comprises an overview of the general geology, geological history, stratigraphy and topography of the area under consideration. Geological, bore-hole and well data has been compiled and tabulated. A geological sketch map is included.

During the last three years much work has been done on laterites in Northern Australia by geologists of the Bureau and in particular those attached to the North Australian Regional Survey. The co-operation of soils officers and geologists in this survey has led to a better understanding of the significance of laterites and of the zones within the profiles. Since several parties from the Bureau are now working in Northern Australia it seemed opportune to discuss the nomenclature of laterites and to suggest terms and definitions so that laterites can be described and mapped in the same way by the several field parties. With this object in view geologists from the Bureau and officers from the North Australian Regional Survey discussed the matter and the following terminology and definitions are circulated now for criticism within the Bureau.

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.
