AUSGeoid98 v.1.0 data files:  (sh57-13)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

Glenormiston, QLD, Sesmic Refraction and Magnetic, 1977 (P447), 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 Glenormiston, QLD, Sesmic Refraction and Magnetic, 1977 (P447), radiometric line data, AWAGS levelled were acquired in 1977 by the QLD Government, and consisted of 5369 line-kilometres of data at 1000m 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.

Species identification of worms from grabs - Leveque Shelf (Browse Basin), Western Australia SOL5754 (GA0340)

In May 2013, Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS) undertook a collaborative seabed mapping survey (GA0340/ SOL5754) on the Leveque Shelf, a distinct geological province within the Browse Basin, offshore Western Australia. The purpose of the survey was to acquire geophysical and biophysical data on seabed environments over a previously identified potential CO2 injection site to better understand the overlying seabed habitats and to assess potential for fluid migration to the seabed. 
Mapping and sampling was undertaken across six areas using multibeam and single beam echosounders, sub-bottom profilers, sidescan sonar, underwater towed-video, gas sensors, water column profiler, grab samplers, and vibrocorer. Over 1070 km2 of seabed and water column was mapped using the multibeam and single beam echosounder, in water depths ranging between 40 and 120 m. The sub-surface was investigated using the multichannel and the parametric sub-bottom profilers along lines totalling 730 km and 1547 km in length respectively. Specific seabed features were investigated over 44 line km using the sidescan sonar and physically and sampled at 58 stations.
Integration of this newly acquired data with existing seismic data will provide new insights into the geology of the Leveque Shelf. This work will contribute to the Australian Government's National CO2 Infrastructure Plan (NCIP) by providing key seabed environmental and geological data to better inform the assessment of the CO2 storage potential in this area of the Browse Basin.
This dataset contains identifications of Polychaetes collected from 64 Smith-McIntyre grabs deployed during GA0340/SOL5754.

Calibration of gravity meters with a quartz-mechanism

Gravity meters with a quartz mechanism can be calibrated on tilt tables, on hillside calibration ranges with stations at different altitude, or on level calibration ranges with stations at the same altitude. Twenty Worden, Sharpe, and Scintrex gravity meters have been calibrated in Canberra on a PEG-1 tilt table borrowed from the Soviet Academy of Sciences. These calibrations agree, to within experimental error, with tilt calibrations by the manufacturers in North America, and calibrations based on sea-level stations along the Australian Calibration Line. Calibrations on hillside calibration ranges differ systematically from other calibrations, and indicate a mean altitude effect of (2.5 Â± 0.5) X 10^-3 um s^-2 m^-1. This altitude effect is higher than the mean of (1.5 Â± 0.3) X 10^-3 micro m s^-2 m^-1 found by pressure-chamber studies in North America and Europe. If quartz-mechanism gravity meters are used either in base station gravity networks, or for field stations in areas with over 500 m of relief, then a correction should be made for this altitude effect, particularly if the anomalies are to be used for geodetic purposes.

Pine Creek Airborne Electromagnetic Data and Procedures for AEM data

This powerpoint was presented at a workshop in Alice Springs March 2011. The goal of the Pine Creek AEM survey is to characterise the electromagnetic response of Paleoproterozoic rocks, particularly graphitic units adjacent to Archean granite domes, and map these units in regions of extensive cover, such as the Woolner Granite, and Daly River Basin areas. The project will also attempt to map key sub-surface unconformities and structures which may have influenced mineralising fluids.
Objectives
To map unconformity and palaeochannel uranium host rocks 
To map the thickness of Kombolgie Subgroup rocks (depth to prospective interface) 
To map graphitic basement conductors 
To map the thickness of regolith cover.

Evidence of evaporite minerals in the Archaean Black Flag Beds, Kalgoorlie, Western Australia

Sediments with ankerite pseudomorphs after gypsum, and possibly also after anhydrite, have been recognised in the greater than 2675 Â± 35 m.y. old Black Flag Beds at Kalgoorlie, Western Australia. This indicates the presence of hypersaline brines during the deposition or diagenesis of these sediments. Recognition of the carbonate pseudomorphs after sulphates supports the conclusion of other recent workers that sedimentary sulphate deposition occurred during the Archaean; added to the growing list of such occurrences, this contradicts earlier conclusions that there are no significant sedimentary sulphates older than about 1000 m.y.

The Ginninderra CH4 and CO2 release experiment: An evaluation of gas detection and quantification techniques

A methane (CH4) and carbon dioxide (CO2) release experiment was held from April – June 2015 at the Ginninderra Controlled Release Facility in Canberra, Australia. The experiment provided an opportunity to compare different emission quantification techniques against a simulated CH4 and CO2 point source release, where the actual release rates were unknown to the participants. Eight quantification techniques were assessed: three tracer ratio techniques (two mobile); backwards Lagrangian stochastic modelling; forwards Lagrangian stochastic modelling; Lagrangian stochastic (LS) footprint modelling; atmospheric tomography using point and using integrated line sensors. The majority of CH4 estimates were within 20% of the actual CH4 release rate (5.8 g/min), with the tracer ratio technique providing the closest estimate to both the CH4 and CO2 release rates (100 g/min). Once the release rate was known, the majority of revised estimates were within 10%. An ensemble approach to estimating the CH4 emission rate proved successful with the ensemble median estimate within 16% for the actual release rate for the blind release experiment and within 2% once the release rate was known. The release also provided an opportunity to assess the effectiveness of stationary and mobile ground and aerial CH4 detection technologies. Sensor detection limits and sampling rates were found to be significant limitations for CH4 detection. A hyperspectral imager’s capacity to image the CH4 release from 100 m, and a Boreal CH4 laser sensor’s ability to track moving targets suggest the future possibility to map gas plumes using a single laser and mobile aerial reflector.
