Report on the Analysis of the Asia Pacific Regional Geodetic Project (APRGP) GPS Campaign 2015

The annual Asia Pacific Regional Geodetic Project (APRGP) GPS campaign is an important activity of the Geodetic Reference Frame Working Group (WG) of the Regional Committee of United Nations Global Geospatial Information Management for Asia and the Pacific (UN-GGIM-AP). This document overviews the data analysis of the APRGP GPS campaign undertaken in 2015. The GPS data were processed using version 5.2 of the Bernese GPS Software in a regional network together with selected IGS (International GNSS Service) sites. The GPS solution was constrained to the ITRF2008 reference frame through adopting IGb08 coordinates on selected IGS reference sites and using the final IGS earth orientation parameters and satellite ephemerides products.

Detailed gravity traverse, northern end Giralia Structure, North West Basin, Western Australia

Gravity observations were made at quarter-mile intervals along the road that joins Bullara and Giralia homesteads. This road crosses the northern end of the Giralia anticline normal to its axis. A seismic reflection profile, which is described in B.M.R. Record 1951 No. 62, has also been run along this road and it is possible to compare the gravity results with the seismic. Gravity station elevations were determined with an accuracy of within 0.1 of a foot and the gravity observations have been reduced to Bouguer anomalies using an elevation correction factor of 0.062 milligals per foot. The results are shown in the form of a profile on the accompanying plate. The surface profile is also plotted and the positions of some of the seismic shot points are shown alongside the gravity station numbers. These results are discussed in this report.

Abminga 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.

The Transient Electromagnetic Method in Australia

Transient electromagnetic (TEM) test surveys have been made at various localities in Australia to evaluate the method. The test surveys described in this paper were made in the Rum Jungle, Mary River and Tennant Creek areas, Northern Territory. Good agreement was generally obtained between TEM results and those observed with other electromagnetic methods, and good correlation was obtained with geology. The theoretical advantages inherent in the method make it attractive under Australian conditions of conductive overburden, and field test results demonstrate these advantages. It was found that the TEM equipment could be used in areas where topography or highly conductive surface conditions severely limit the effectiveness of other geophysical methods. The use of large loops with sides 100-150 m enable large areas to be surveyed quickly, while smaller loops proved useful in delineating anomalies accurately. Different loop sizes with loop-overlap were used to assist quantitative interpretation. Transient electromagnetic scale modelling programs have also been made and two examples are given which demonstrate how interpretation can be improved by such programs. A model study of the Woodlawn copper-lead-zinc deposit indicated that the orebody would have been detected at depths of up to 200 m. Modelling an area known as the Gubberah Gossan in the Northern Territory demonstrated that the anomaly pattern could be caused by resistive quartz-sphalerite mineralization in a conductive carbonaceous shale unit.

Towards a homogeneous earthquake catalogue for Australia

An earthquake catalogue based on the moment magnitude scale is required for calculation of seismic hazard in Australia. However, the estimation of moment magnitudes for small to moderate sized earthquakes is not a routine process at seismic observatories, resulting in a catalogue mainly based on the local magnitude scale for Australia. In this study we explore the application of an automated procedure to estimate moment magnitudes by minimizing the misfit between observed and synthetic displacement spectra. We compile a reference catalogue of 15 earthquakes with moment magnitude values between 3.8 and 5.4 which were based on previous studies.   The moment magnitudes were then recalculated and we find that the estimated moment magnitudes are in good agreement with reference values with differences mainly lower than 0.2. However, the reported local magnitudes of the selected events are consistently higher than the reference values with differences between 0.3 and 1.0. The automated procedure will be applied to compute moment magnitudes of the well recorded events in Australia, and to derive a scaling relation between local magnitude and moment magnitude.
This abstract was submitted and presented to the 2016 Australian Earthquake Engineering Society Conference (AEES) ( https://aees.org.au/aees-asian-seismological-commission-conferences/)

Arenite Area A, WA, 1994 and Arenite Area B, WA, 1996 (P772), radiometric line data, AWAGS levelled

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.
 This Arenite Area A, WA, 1994 and Arenite Area B, WA, 1996 (P772), radiometric line data, AWAGS levelled were acquired in 1994 by the WA Government, and consisted of 19723 line-kilometres of data at 250m 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.

L053 Westbourne seismic reflection and refraction survey, south of Tambo, QLD, 1961

Aeromagnetic and gravity surveys were made in the Tambo-Augathella area by Magellan Petroleum Corporation in 1959 and 1960 respectively. A probable fault shown in the magnetic interpretation is almost coincident with a zone of steep gravity gradients which was interpreted as indicative of a fault or of steeply dipping strata. However, the normal gravity interpretation would indicate a deeper cross-section to the south-east of this zone, whereas the magnetic interpretation suggests that the fault is downthrown to the northwest.
The present survey was undertaken by the Bureau of Mineral Resources to find out which interpretation was the more probable. A reflection seismic traverse was shot at right angles to the closed gravity 'high' and across the zone of steep gravity gradients. Results show that the closed gravity 'high' is the expression of an anticline and that the zone of stoep gravity gradients is caused by steep dip to the south-east on the flank of the anticline. The gravity interpretation is therefore found to be more representative of actual conditions.

AUSGeoid98 v.1.0 data files:  (sk50-10)

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.
