Murray Basin (Ana Branch, Pooncarie), NSW, 1981 (P465), 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 Murray Basin (Ana Branch, Pooncarie), NSW, 1981 survey were acquired in 1981 by the NSW Government, and consisted of 14574 line-kilometres of data at 3000m line spacing and 150m 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.

Woomera No 1 Bore, South Australia Of Clarence River Basin Oil Exploration Co NL

Woomera Bore 1 was drilled to a depth of 2,005 feet. Four formations were penetrated believed to be of Cambrian and/or Proterozoic age. The nature of these beds suggests that the area has no petroleum prospects. The age of the strata penetrated is uncertain, as no fossils have been observed. No results were obtained from a formation test carried out with the packer set at 1,445 feet.

AUSGeoid98 v.1.0 data files:  (sh57-10)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files.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.

This magnetic grid has a cell size of 0.00048 degrees (approximately 50m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2002 by the NSW Government, and consisted of 29054 line-kilometres of data at 250m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.

Australian Geomagnetism Report 2005

During 2005 Geoscience Australia operated geomagnetic observatories at Kakadu and Alice Springs in the Northern Territory; Charters Towers in Queensland; Learmonth and Gnangara in Western Australia; Canberra in the Australian Capital Territory; Macquarie Island, Tasmania, in the sub-Antarctic; and Casey and Mawson in the Australian Antarctic Territory. Three geomagnetic repeat stations were also occupied in 2005. The Australian Geomagnetism Report 2005 (Volume 53) describes instrumentation and activities; absolute reference magnetometers; data distribution; and presents monthly and annual mean magnetic values, plots of hourly mean magnetic values and K indices at the magnetic observatories and repeat stations operated by Geoscience Australia during calendar year 2005.

The 1960 Chilean earthquake and tsunami helped prepare Australia for tsunami

In the early hours of 23 May 1960, an earthquake and tsunami struck Chile. There were no morning television shows and newspapers had already been printed for the day. Tsunami warning systems for Australia did not exist and there were no tools nor knowledge to help Australia prepare. Thankfully, we live in different times.

The data used to produce this grid was acquired in 1983 by the VIC Government, and consisted of 4548 line-kilometres of data at 250m line spacing and 80m terrain clearance. The grid was produced by applying the colours red to the Potassium ground concentration, green to the Thorium concentration and blue to the Uranium concentration. The colours were clipped to a 99% linear scale. These colours were transparent over a shaded Total Count. This clipping will necessarily introduce some artefacts into the ratio grids in areas of very low radioelement concentrations. The 3-band image was superposed on the sun shaded TC grid of the same survey to produce the final image.
