Elkedra ties, NT, 1999 (P1006), 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 Elkedra, NT, 1999 survey were acquired in 1999 by the NT Government, and consisted of 121182 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.

Cobar P5009 EXT 4 reduced to pole fft 1st vertical derivative grid

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 Cobar P5009 EXT 4 reduced to pole fft 1st vertical derivative grid is the first vertical derivative of the TMI RTP grid of the Cobar Magnetic and Radiometric Survey, 2021 survey.
This grid has a cell size of 0.00039074 degrees (approximately 40m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m 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. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the Cobar Magnetic and Radiometric Survey, 2021 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.

Gove Peninsula Special 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. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

Surface Geology of Australia 1:2.5 million scale dataset 2012 edition

The 1:2.5M scale geology of Australia data documents the distribution and age of major stratigraphic, intrusive and medium to high-grade metamorphic rock units of onshore Australia. This edition contains the same spatial content as the previous edition, but its geological attribute data is more complete than the 2010 edition. 
The dataset was compiled to use at scales between 1:2.5 million and 1:5 million inclusive. The units distinguished/mapped mainly represent stratigraphic supergroups, regional intrusive associations and regional metamorphic complexes. Groupings of Precambrian units in the time-space diagram are generally separated by major time breaks; Phanerozoic units are grouped according to stratigraphic age i.e. System/Period. The time-space diagram has the added benefit that it provides a summary of units currently included on the themes. The method used to distinguish sedimentary and many volcanic units varies for each geological eon as follows: 
 - Cainozoic units are morphological units which emphasise the relationship of the sedimentary fill to the landscape.
 - Mesozoic units are regionally extensive to continent-wide time-rock units which emphasise the System of Period(s).
 - Paleozoic units are stratotectonic units that emphasise either the dominant System or Period(s) or the range of Periods.
 - Proterozoic units are commonly regional stratotectonic units - separated by major time breaks and split into the Paleoproterozoic, Mesoproterozoic and Neoproterozoic Eras - which are generally unique to each cratonic region.
 - Archaean units are regional lithological units grouped into broad time divisions.
Metamorphic units are lithological units which emphasise the metamorphic facies and timing of the last major metamorphic event.

Adelaide International Map of the World (IMW) 1:1 000 000 topographic map

The International Map of the World (IMW) series is no longer maintained, and printed copies of this map are no longer available. The Australian portion of the series consists of 49 maps. They were produced to an international specification using the R502 series at 1:250,000 scale as source material. Production commenced in 1926 and was completed in 1978. The maps were revised from time to time and the last reprint was undertaken in 2003. Each standard map sheet covers 4 degrees of latitude by 6 degrees of longitude and was produced using a Lambert Conformal Conic projection with 2 standard parallels. The series has recently been superseded by the 1:1 000 000 topographic map general reference.

AUSGeoid98 v.1.0 data files:  (sk52-06)

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.

Kingoonya - dose rate no nasvd grid (AWAGS)

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 potassium (K), uranium (U) and thorium (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. The total dose rate is due to natural sources of radiation and is computed by adding estimates of cosmic dose at ground level to the terrestrial dose. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered total dose rate grid. 
The Geological Survey of South Australia commissioned the Gawler Craton Airborne Survey (GCAS) as part of the PACE Copper initiative. The airborne geophysical survey was flown over parts of the Gawler Craton in South Australia. The program was designed to capture new baseline geoscientific data to provide further information on the geological context and setting of the area for mineral systems. 
This Kingoonya - dose rate no nasvd grid (AWAGS) has a cell size of 0.0004 degrees (approximately 41m) and shows the total dose rate of the Kingoonya Airborne Magnetic Radiometric and DEM survey, SA, 2018 survey. The data used to produce this grid was acquired in 2018 by the SA Government, and consisted of 149477 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Complete list of General Infrasound Abstracts - Infrasound Technology Workshop 2004

Large atmospheric acoustic sources such as: volcanic eruptions, bolides (terminating meteorite explosions), the ocean surface, chemical and nuclear detonations generate copious quantities of infrasound (low frequency sound) that can propagate several thousand kilometres. Using the appropriate recording equipment, infrasound from various sources can be detected and used to infer certain knowledge about the source mechanism or atmosphere through which it travelled.
Each year an Infrasound Technology Workshop is organised to  provide researchers from various international institutions the opportunity to meet with colleagues and present current research results in an informal setting.
The Infrasound Technology Workshop 2004 was hosted by Geoscience Australia in Hobart, Tasmania from 29 November to 3 December 2004. The Workshop was organised in cooperation with the Provisional Technical Secretariat of the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) in Vienna.
Listed below is the complete list of abstracts submitted to the general infrasound session in author's surname order. 28 abstracts were submitted for this workshop.  
A special Volcano Infrasound session was held at the Workshop, see Geocat #69616 to view abstracts.
