AUSGeoid98 v.1.0 data files: Throssell (sg51-15)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

New Insights into the geodiversity of the southeast Indian Ocean seafloor revealed by Malaysia Airlines flight MH370 search data

A large multibeam echo sounder (MBES) dataset (710, 000 km2, inclusive of transit data) was acquired in the SE Indian Ocean to assist the search for Malaysia Airlines Flight 370 (MH370). Here, we present the results of a geomorphic analysis of this new data and compare with the Global Seafloor Geomorphic Features Map (GSFM) that is based on coarser resolution satellite-derived bathymetry data. The analyses show that abyssal plains and basins are significantly more rugged than their representation in the GSFM, with a 20% increase in the extent of hills and mountains. The new model also reveals four times more seamounts than presented in the GSFM, suggesting a greater number of these features than previously estimated for the broader region and indeed globally. This is important considering the potential ecological significance of these high-relief structures. Analyses of the new data also enabled knolls, fans, valleys, canyons, troughs and holes to be identified, doubling the number of discrete features mapped and revealing the true geodiversity of the deep ocean in this area. 
This high-resolution mapping of the seafloor also provides new insights into the geological evolution of the region, both in terms of structural, tectonic, and sedimentary processes. For example, sub-parallel ridges extend over approximately 20% of the area mapped and their form and alignment provide valuable insight into Southeast Indian Ridge seafloor spreading processes. Rifting is recorded along the Broken Ridge – Diamantina Escarpment, with rift blocks and well-bedded sedimentary bedrock exposures discernible down to 2,400 m water depth. Ocean floor sedimentary processes are represented in sediment mass transport features, especially along and north of Broken Ridge, and pockmarks (the finest-scale features mapped) south of Diamantina Trench. 
The new MBES data highlight the complexity of the search area and serve to demonstrate how little we know about the 85-90% of the ocean floor that has not been mapped with this technology. The availability of high-resolution and accurate maps of the ocean floor can clearly provide new insights into the Earth’s geological evolution, modern ocean floor processes, and the location of sites that are likely to have relatively high biodiversity.

Mt Elizabeth, WA,1993 (P626), 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 Mt Elizabeth, WA,1993 (P626), radiometric line data, AWAGS levelled were acquired in 1993 by the WA Government, and consisted of 50696 line-kilometres of data at 400m line spacing and 60m 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.

p200880 Central Arunta Gravity spherical cap Bouguer Vert Deriv geodetic

Gravity data measure 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. 
This p200880 Central Arunta Gravity spherical cap Bouguer Vert Deriv geodetic is the first vertical derivative of the spheical cap Bouguer anomaly grid for the Central Arunta Gravity Survey, NT (P200880). This gravity survey was acquired under the project No. 200880 for the geological survey of NT. The grid has a cell size of 0.0037 degrees (approximately 395m). A total of 11829 gravity stations at variable spacing between 500m and 4000m were acquired to produce this grid. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

Preliminary report on iron ore deposits near Maude Creek and Francis Creek, Burrundie area, Northern Territory

Reconnaissance surveys have shown that an area of approximately eight miles by four miles in the vicinity of Maude and Francis Creeks, near Burrundie, Northern Territory, contains six groups of major ironstone deposits. The deposits crop out discontinuously over a length of about 15 miles in a favourable bed of the Lower Proterozoic Masson Formation. The total length of ironstone outcrop is about 15,000 feet, the width ranges from 30 to 80 feet, and the minimum depth is estimated to range from 100 feet to 200 feet. Until assay results are available, the highest grade of ironstone is visually estimated at about 60 percent. One of the largest deposits has an ironstone potential of 10,000 tons per vertical foot.

Statistical Modelling of Severe Wind Gust

The modelling of severe wind gust is a fundamental part of any wind hazard assessment.
Statistical modelling approaches are usually used to describe the probability of occurrences of extreme
winds. The classical extreme value theory based on the generalized extreme value (GEV) distribution and the more recently developed peaks over threshold (POT) and the use of generalized Pareto distribution (GPD) are investigated. Practical issues such as the threshold selection and model validation are also discussed.
Severe wind gust models were developed for a number of locations in Perth. Estimates of 50 and 100 year return period events are compared with estimates published by the Standards Australia for Perth (Region A), which are based on a single site. For coast sites, the predicted wind gust speeds are similar to those published by the Standards, while the inland sites have smaller wind gust speeds.

Darwin (Urban Development), NT, 1974 (P411), 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 Darwin (Urban Development), NT, 1974 survey were acquired in 1974 by the NT Government, and consisted of 803 line-kilometres of data at 500m 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.

Carnarvon Shelf Infaunal Diversity

Geoscience Australia carried out a marine survey on Carnarvon shelf (WA) in 2008 (SOL4769) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wave generated currents. Data and samples were acquired using the Australian Institute of Marine Science (AIMS) Research Vessel Solander. Bathymetric mapping, sampling and video transects were completed in three survey areas that extended seaward from Ningaloo Reef to the shelf edge, including: Mandu Creek (80 sq km); Point Cloates (281 sq km), and; Gnaraloo (321 sq km). Additional bathymetric mapping (but no sampling or video) was completed between Mandu creek and Point Cloates, covering 277 sq km and north of Mandu Creek, covering 79 sq km. Two oceanographic moorings were deployed in the Point Cloates survey area. The survey also mapped and sampled an area to the northeast of the Muiron Islands covering 52 sq km.

Australian Petroleum Systems. Petrel Sub-basin module

This module is part of the AGSO-APIRA Australian Petroleum Systems Project. 
Eight basin modules were examined which covered almost the entire North West Shelf, the Petrel Sub-basin, as well as the Papuan basin in PNG. 
Two relational databases were established containing the biostratigraphic data (STRATDAT) and reservoir, facies and hydrocarbon shows data (RESFACS). These databases were linked by application programs which allow time series searching using geologically intelligent routines. 
Petroleum systems analyses were conducted on each area, with key results focussing upon the comparison of source quality and timing of generation between similar systems in different areas.
