Davis Multibeam Survey 2016/17, Antarctica (GA-0357/AAP 5093) - High Resolution Backscatter Grid

Geoscience Australia, the Royal Australian Navy (RAN) and the Australian Antarctic Division (AAD) conducted a hydrographic surveying and seafloor characterisation survey in nearshore waters offshore from Davis Station in the Australian Antarctic Territory. 
The multibeam data was acquired during January-February 2017 using two workboats. Geoscience Australia used the AAD workboat Howard Burton and the Royal Australian Navy used their Antarctic Survey Vessel (ASV) Wyatt Earp. The survey is a component of Australian Antarctic Program (AAP) Project 5093 Hydrographic Surveying and Seafloor Characterisation Program (Chief Investigator: Ursula Harris, AAD). 
The objective of the survey was to map the seabed environment in shallow (<300 m) coastal waters adjacent to Davis station in the Vestfold Hills region, to obtain data for the compilation of nautical charts and to acquire fundamental baseline data necessary for informed environmental management, science, infrastructure and logistical operations. 
Data collected during the survey includes high-resolution multibeam bathymetry and backscatter data, sediment samples, seafloor imagery and sub-bottom profiles. 
This dataset comprises a backscatter grid from multibeam sonar data acquired using the AAD workboat Howard Burton, gridded at 2 m spatial resolution, covering a combined area of 90 km2. The Chief Scientist onboard the Howard Burton was Dr. Jodie Smith (Geoscience Australia).

NT Road Surveys 1987-1997 Musgrave Block (P199683), 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 NT Road Surveys 1987-1997 Musgrave Block (P199683) contains a total of 472 point data values acquired at a spacing between 200 and 1000 metres. The data is located in NT and were acquired in 1996, under project No. 199683 for Northern Territory of Australia (Northern Territory Geological Survey).

Tsunami Animation - Propagation

As the tsunami moves across the open ocean it is almost undetectable on the ocean surface.
In this example, the tsunami waves are only about half a metre high but have a wavelength of 200 kilometres. Travelling at speeds of up to eight or nine hundred kilometres an hour (the speed of a commercial passenger jet), it will take each wave about 15 minutes to pass a slow moving ship.

Applications of Potential Field Methods over the Eastern Goldfields Superterrane (EGST) of Western Australia

The Neoarchaean Eastern Goldfields Superterrane (EGST) forms the eastern half of the Yilgarn
Craton and hosts many major orogenic gold and nickel deposits. This well-endowed region has been
the focus of numerous geophysical, geological and geochemical studies that are aimed at better
understanding the architecture and broad structure of the region. This contribution documents the
application of various methods to exploit potential fields (gravity and airborne magnetics)
observations over the region at various scales. The work was conducted by the Yilgarn projects of
the pmd*CRC (Predictive Mineral Discovery Cooperative Research Centre) and the results have
previously been held under confidentiality agreements.

A regional review of the offshore Gippsland Basin

Petroleum exploration carried out in the offshore Gippsland Basin between March 1976 and June 1987 has been reviewed to provide an overview of the distribution of the petroleum accumulation with reference to the major tectonic subdivisions delineated by the compiled and synthesised seismic structure contour maps based on interpretive company data. These maps, together with the geological cross - sections, give an indication of the formation and evolution of the Gippsland Basin during Early Cretaceous and Late Cretaceous to Tertiary tectonic events and the change from a largely extensional to a compressive tectonic regime during the Eocene. Most of the traps at the top of the Latrobe Group, and some of the traps in the intra-Latrobe Group section, that are easily mappable by the prevailing seismic technology have already been found. However, it is likely that undetected prospects exist in areas of currently poor quality seismic data and/or severe seismic interpretation problems. In the northwestern part of the basin, the poor quality of seismic data below the Eocene beds is attributed to the absorption of seismic energy caused by the presence of shallow, thick coal seams. In the central part of the basin, errors in time-depth conversion are caused by the presence of Miocene channels filled with high velocity sediments, and in the eastern and southeastern deep water parts of the basin, by the presence of submarine canyons. It is suggested that the application of recent developments in seismic technology will enable the delineation of additional prospects in these areas.

Cape York (Aurukun, Coen), QLD, 1986 (P520), 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 Cape York (Aurukun, Coen), QLD, 1986 survey were acquired in 1986 by the QLD Government, and consisted of 25998 line-kilometres of data at 1500m line spacing and 150m 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.

AUSGeoid98 v.1.0 data files:  (sl49-02)

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.

The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This magnetic grid has a cell size of 0.00083 degrees (approximately 88m).The data are in nanoTesla per metre (or nT/m). To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid. This survey grid is essentially levelled to AWAGS. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-15 geomagnetic reference model using a data representative date and elevation representative of the survey. A further enhancement has been completed to enhance the geological interpretation of the data.
