Australian seismological report, 1994

Each year in Australia there are on average one earthquake of magnitude 5.3 or greater and about 200 of magnitude 3 or greater, excluding aftershocks. The larger ones are a threat to life and property as was so tragically demonstrated by the 1989 Newcastle earthquake. Analysis of the small ones will yield clues to the cause, location and style of future large ones. This report contains information on the 1994 earthquakes and is the fifteenth compiled by the Australian Geological Survey Organisation (and its predecessor Bureau of Mineral Resources) since 1980. Its purposes are to aid the study of earthquake risk in Australia, and to provide information on Australian and world earthquakes for scientists, engineers and the general public. The report has six main sections: Australian region earthquakes; Isoseismal maps; Network operations; Accelerograph data; Principal world earthquakes; and Monitoring of nuclear explosions.  A new section on tsunamis has been added.

Ebagoola 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD.

The Mud Tank Carbonatite, Strangways Range, central Australia

The Mud Tank Carbonatite at the eastern end of the Strangways Range, about 100 km northeast of Alice Springs, was the first to be recognised in Australia. Crystalline carbonate rocks containing apatite, magnetite and zircon occur in a northeast-trending zone about 2 km long and up to 700 m wide, and in a second, much smaller, lens about 2 km to the southwest. The rocks show banding, owing to differences in texture and composition, and can be broadly divided into crystalline carbonate rocks with subordinate apatite, magnetite, phlogopite, chlorite, and soda-amphibole; foliated micaceous carbonate rocks rich in pale brown phlogopite; and feldspathic carbonate rocks with various amounts of sodic plagioclase, clinopyroxene, green-brown amphibole, and brown biotite. This last group is considered to be largely of hybrid origin.  Calcite and dolomite occur in various proportions in all the rock types. Country rocks are schists and gneisses of the Early Proterozoic Arunta Block. Trace element concentrations, particularly of niobium and rare earths, are within established ranges for carbonatites, but well below economic values. On the other hand, zircon crystals of gem quality are present in the soil and colluvium overlying the carbonatite, and vermiculitic mica has developed in the weathered zone within about 40 m of the surface.

GSWA Merredin Bruce Rock South Total Count Grid Geodetic

This GSWA Merredin Bruce Rock South Total Count Grid Geodetic is an airborne-derived radiometric total count window countrate grid for the Merredin-Bruce Rock, WA, 1997 survey. The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of total count (K), total count (U) and total count (Th). The data collected 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 Merredin Bruce Rock South Total Count Grid Geodetic has a cell size of 0.00038 degrees (approximately 39m). The data are in units of counts per second (cps). The data used to produce this grid was acquired in 1997 by the WA Government, and consisted of 27533 line-kilometres of data at 150m line spacing and 50m terrain clearance.

Backscatter grid of Lord Howe Island

Geoscience Australia carried out a marine survey on Lord Howe Island shelf (NSW) in 2008 (SS062008) 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 wavegenerated 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.
lh_back_8m is a backscatter grid of the Lord Howe survey area produced from the processed EM300 backscatter data of the survey area using the CMST-GA MB Process.

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.
