Sydney 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The International Map of the World (IMW) series is no longer maintained, and printed copies of this map are no longer available.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 The series has recently been superseded by the 1:1 000 000 topographic map general reference.

Gawler Craton Airborne Survey, Tranche 2, Block 8b, Billa Kalina, 2017 (P1300), magnetic line data

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 Gawler Craton Airborne Survey, Tranche 2, Block 8b, Billa Kalina, 2017 survey were acquired in 2017 by the SA Government, and consisted of 90584 line-kilometres of data at 200m line spacing and 60m terrain clearance.

MRTAS NW Tasmania doserate grid geodetic

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 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 terrestrial dose rate grid.
This MRTAS NW Tasmania doserate grid geodetic has a cell size of 0.00042 degrees (approximately 41m) and shows the terrestrial dose rate of the North West Tasmania, Tas, 2001 (WTRMP Area B).

AUSGeoid98 v.1.0 data files:  (se55-07)

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.

Legacy stream sediment sample reanalysis - Red River, Hann River, Ebagoola, Coen, Georgetown, Kakadu, Araluen, Brindabella, Hedleys Creek, and Mammoth Mines Surveys

Geoscience Australia has a large holding of surface sediment samples, such as stream and overbank sediments, from geochemical surveys conducted over more than 50 years across the Australian continent. Geochemical data from these surface materials are of national importance as they can contribute significantly to establishing geochemical environmental baselines and their use in land management, as well as aiding in the discovery of new mineral deposits. Samples from these legacy surveys provide valuable insights into areas of Australia that are remote, difficult to access, or have since been developed. The age of a large number of these surveys, however, means that the original results included data for a&nbsp;smaller range of chemical elements, typically with poorer analytical precision and accuracy than those of modern surveys. This small range of chemical elements also typically doesn’t include important elements for modern use, such as critical minerals (i.e. Co, Bi, REEs), which are increasing in their importance. As part of Geoscience Australia’s Exploring for the Future program, a collection of over 9000 samples from these surveys was reanalysed using modern analytical techniques for a&nbsp;suite of 60 chemical elements. These samples cover several regions within Australia, including Kakadu, Cape York, the Mount Isa region, and near the Canberra region. The new analytical data maximise the value of the historical geochemical surveys and will provide new insights into the mineral potential of these regions and improve the quality of geochemical environmental baselines.&nbsp;

This data release includes: 1) information on the surveys and their samples; 2) quality assurance results; 3) a discussion of sample preparation and analytical methods used; 4) results for total content geochemistry (XRF and LA-ICP-MS); and 5) individual element maps for each of the regions for preliminary interpretation of the data.

Acquisition and release of this dataset forms part of a larger program aimed at creating a levelled geochemical baseline for the whole Australia (Main and Champion, 2020).

Intraplate seismic events off Sumatra: 3-D source evolution

Four dominantly strike-slip earthquakes have occurred in recent years in the Wharton Basin off the coast of Sumatra. The southernmost was the Mw 7.9 event on 2000 June 18, followed by the largest known intraplate earthquake the Mw 8.6 event on 2012 April 11, with an
Mw 8.2 ‘aftershock’ within a few hours. The most recent Mw 7.8 event on 2016 March 2 happened in an area with no previously recorded large earthquake. For each event we have undertaken analysis of the high-frequency energy radiation as a function of time, using a
suite of global stations with good azimuthal control, so that we can map out source evolution in three-dimensions. Each of the events involves a component of conjugate faulting. The largest energy emission links to near north-south features reflecting seafloor topography, with linking east-west rupture. High-frequency radiation is emitted through the full thickness of the lithosphere in the main part of the event. As frequency is reduced there is a distinct change in radiation characteristics, though migration of energy emission to depth is common. Significant energy release occurs at depths where deformation would be expected to be ductile, suggesting differences between instantaneous and long-term rheology. The complex behaviour recognised in the 2012 great earthquakes looks to be a feature of strike-slip events in this zone off the subduction zone. 
Each of the events occurs in a region with slightly lower shear wavespeed than their surroundings in surface wave tomography models. The contrasts suggest changes in the physical parameters of the Indo-Australian plate in the area of breakup. The conjugate ruptures in response to an oblique stress-field form part of a diffuse zone of deformation associated with the impending divorce between the Indian and Australian components of the plate.

Description, Distribution and Potential CO2 Storage/Seal Capacity of the Cenozoic Sandstones and Carbonates, Browse Basin, Western Australia

The Browse Basin is located in the southern Timor Sea region of Australia's North West Shelf and covers an area of ~140,000 km2. It was identified as containing potential Environmentally Suitable Sites for carbon dioxide (CO2) Injection (ESSCI) by the Australian Petroleum CRC's GEODISC program (1999-2003). A regional geological reconnaissance of Cenozoic sandstone and carbonate sequences in the Browse Basin was undertaken in 2007 to determine the potential storage and sealing capacity for geological storage of CO2, the results of which are presented in this report. Methods included the review of available literature and well-completion reports, lithological and mineral analysis of selected well cuttings and interpretation of the wire-line and seismic response of the Cenozoic section.

Groundwater monitoring in California's Central Valley using satellite remote sensing

Rapid population growth and an increasing demand for water has been depleting groundwater resources in the Central Valley of California for decades. The lack of sufficient ground monitoring networks poses serious challenges to water management efforts and puts the sustainability of groundwater resources at risk. This seminar will demonstrate how the satellite remote sensing techniques of Interferometric Synthetic Aperture Radar (InSAR) and the Gravity Recovery and Climate Experiment (GRACE) can be applied to monitor groundwater resources and aquifer response to drought. The final part of this seminar will describe how GA is currently trialling the demonstrated methods as remote groundwater monitoring tools in the Great Artesian Basin of Australia.
