Pyramid 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Flinders Project, Clara Rivers Survey CR27460. (P199511), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Flinders Project, Clara Rivers Survey CR27460. (P199511) contains a total of 328 point data values acquired at a spacing between 200 and 1000 metres. The data is located in QLD and were acquired in 1995, under project No. 199511 for Western Mining Corporation Ltd.

Helen Springs - Monmoona, NT, 1993 (P611), 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 Helen Springs/Beetaloo, NT, 1993 survey were acquired in 1993 by the NT Government, and consisted of 117753 line-kilometres of data at a line spacing between 300m and 300m, 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.

Pacific Sea Level and Geodetic Monitoring Project Levelling & GNSS Monitoring Survey Reports: Nuku’alofa, Tonga, April 2019

The Australian Bureau of Meteorology (BoM), Geoscience Australia (GA) and the Pacific Community (SPC) work together on the Australian Aid funded Pacific Sea Level and Geodetic Monitoring Project (PSLGMP). The project is focused on determining the long-term variation in sea level through observation and analysis of changes in the height of the land (using Global Navigation Satellite System (GNSS) data) and changes in the sea level (using tide gauges managed and operated by the BoM. It is the role of GA and SPC to provide information about ‘absolute’ movement of the tide gauge (managed by BoM) using GNSS to continuously monitor land motion and using levelling (SPC) to measure the height difference between the tide gauge and GNSS pillar every 18 months.
Land movement caused by earthquakes, subsidence and surface uplift have an important effect on sea level observations at tide gauges. For example, a tide gauge connected to a pier which is subsiding at a rate of 5 mm per year would be observed as a rate of 5 mm per year of sea level rise at the tide gauge. Because of this, it is important to measure, and account for, the movement of land when measuring ‘absolute’ sea level variation - the change in the sea level relative to the centre of the Earth. Relative sea level variation on the other hand is measured relative to local buildings and landmass around the coastline.
Geoscience Australia’s work enables more accurate 'absolute' sea level estimates by providing observations of land motion which can be accounted for by BoM when analysing the tide gauge data.
This report provides the results of the GNSS monitoring survey &amp; high precision level survey completed between the Sea Level Fine Resolution Acoustic Measuring Equipment (SEAFRAME) tide gauge and the GNSS Continuously Operation Reference Station (CORS) in Nukualofa, Tonga from 7th to 19th July 2019. It also provides an updated height of the tide gauge derived from GNSS time series analysis and precise levelling observations.

Undiscovered resource assessment methodologies and application to the Bonaparte Basin

A medium term forecast of undiscovered hydrocarbon resources for the Mesozoic and Palaeozoic petroleum systems of the Bonaparte Basin has been generated by Geoscience Australia.  It concludes that there is a mean expectation that 56 gigalitres (350 million barrels) of oil, 82 billion cubic metres (2.9 trillion cubic feet) of gas, and 18 gigalitres (115 million barrels) of condensate are likely to be discovered in the next ten to fifteen years.  This assessment is highly sensitive to the modelled number of wildcat wells to be drilled and is based on historical drilling success rates.  The assessment process only assesses existing play types and cannot account for new or unconceived plays.
This assessment is significantly smaller than the US Geological Survey assessment released in 2000, and the difference is mainly attributable to the timeframe being addressed by the two different assessment processes and the level to which reserves growth is modelled.  The Geoscience Australia forecast is for the medium term with no reserves growth modelled whereas the USGS forecast approximates an ultimate discovery assessment with reserves growth incorporated.
An appropriate assessment methodology is critical when attempting to undertake an assessment and should be selected to answer specific questions.  The Geoscience Australia methodology is a discovery-process (or creaming curve) model and the assessment results are primarily used for input into production forecasts.  The assessment process has been revised with this new assessment being a petroleum system approach which is more suitable than the migration fairway approach used in the previous resource estimations.
Reserves growth has been identified by the US Geological Survey as a critical element in estimating future hydrocarbon supply.  Research is being directed within Geoscience Australia to determine its effect on its resource assessments.

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.

An inexpensive and efficient double-tube, hand-coring device

A double-tube coring device able to retain sampled core, to recover sandy sediments, and to be easily extracted, has been designed. It consists of two PVC pipes with an intervening air space. The inner tube takes the main stress of coring, the outer tube acts as a sleeve to provide an environment of minimum friction for withdrawal. The corer is fitted with an anvil, and driven into the sediment by hammer blows. Sensitive variation of hammering force when cutting the core enables excellent recovery, with little or no compaction, of a range of sediment types.
