Ayers Rock, NT, 1988 (P558), 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 Ayers Rock, NT, 1988 (P558), radiometric line data, AWAGS levelled were acquired in 1988 by the NT Government, and consisted of 16441 line-kilometres of data at 500m line spacing and 100m 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.

Drilling Operations In The Sydney Basin New South Wales, 1958-1962 Of Australian Oil And Gas Corporation Limited Farmout Drillers No Liability And Exoil (N.S.W.) Pty Limited

Mulgoa No. 2 Well was located in the central-western part of the Sydney Basin, about 35 miles west of Sydney, New South Wales. The well was drilled by the Operator, Australian Oil and Gas Corporation Limited, using a Bucyrus Erie 48-L cable-tool rig, to a total depth of 5630 feet. Drilling commenced on 20th September, 1958, and was completed on 5th November, 1959. A programme of coring and gas sampling was carried out, but no electric logging, perforating or testing operations were undertaken.
The well penetrated 2498 feet of Triassic shales and sandstones and 3132 feet of Permian coal measures, sandstones, shales, and siltstones. 
The objective of the drilling operation was to test the petroleum potential of the Permian strata in the Mulgoa Anticline. Pre-Permian rocks were expected between 5000 and 5200 feet but the well was still in sediments of Permian age when mechanical difficulties caused it to be abandoned at 5630 feet. The well was sited on the eastern flank of the anticline, some 15 miles east (basinwards) of outcropping Permian strata.
Many natural gas shows were encountered in the Triassic and Permian beds but none proved to be of commercial significance. The only large flows of natural gas were at 2579 feet and at 3558 to 3559 feet, and these proved to be blowouts in coal seams. Flows in both cases quickly subsided. Orifice meter tests of twelve gas flows gave a maximum yield of 40 Mcf/D, reducing to 10 Mcf/D after 20 hours.
The stratigraphic drilling operation at Mulgoa No. 2, New South Wales, was subsidized under the Petroleum Search Subsidy Act 1957-1958, from surface to total depth.

The Application of speaker recognition techniques in the detection of tsunamigenic earthquakes

Tsunami warning procedures adopted by national tsunami warning centres largely rely on the classical approach of earthquake location, magnitude determination, and the consequent modelling of possible tsunami waves. Although this approach is based on known physics theories of earthquake and tsunami generation processes, this may be the main shortcoming due to the need to satisfy minimum seismic data requirement to estimate those physical parameters. At least four seismic stations are necessary to locate the earthquake and a minimum of approximately 10 minutes of seismic waveform observation to reliably estimate the magnitude of a large earthquake similar to the 2004 Indian Ocean Tsunami Earthquake of Mw9.2. Taking into account the possibility of close seismic station saturation, the total time to tsunami warning could be more than half an hour. In attempt to reduce the time of tsunami alert a new approach is proposed based on the classification of tsunamigenic and non tsunamigenic earthquakes using speaker recognition techniques. A Tsunamigenic Dataset (TGDS) was compiled to promote the development of machine learning and pattern recognition techniques for application to seismic trace analysis and, in particular, tsunamigenic event detection, and compare them to existing seismological methods. The TGDS contains 2314 trace sets (13884 individual traces), and covers 227 off shore events (87 tsunamigenic and 140 non-tsunamigenic earthquakes with M6) from January 2000 to December 2011, inclusive. Only temporally isolated events were included in the dataset to simplify and expedite initial development of suitable feature representations.
A Support Vector Machine (SVM) classifier using a radial-basis function (RBF) kernel was applied to spectral features derived from 400-second frames of 3-component, 1-Hz broadband seismometer data. Ten-fold cross-validation was used during training to choose classifier parameters. Voting was applied to the classifier predictions provided from each station to form an overall prediction for an event. The F1 score (harmonic mean of precision) was chosen to rate each classifier due to the imbalance between representative number of events in the tsunamigenic and non-tsunamigenic classes. The described classifier achieved an F1 score of 0.923, with tsunamigenic classification precision and recall/sensitivity of 0.928 and 0.919 respectively. The system requires a minimum of 3 stations with ~400 seconds of data each to make a prediction. The accuracy improves as further stations and data become available.
