AUSGeoid98 v.1.0 data files: Mount Whelan (sf54-13)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

The larger Foraminifera of the Lower Miocene of Victoria

One of the outstanding features of the Lower Miocene beds in Victoria is the presence of many larger foraminiferal species, many of the genera being restricted to this horizon, thereby being extremely valuable as zonal fossils, and affording excellent markers for the correlation of beds in different areas. The larger foraminifera have been found abundantly in the borings that have been put down for oil and water throughout the State. They also occur in several outcrops. The genera restricted to the Lower Miocene of Victoria include-Lepidocyclina, Cycloclypeus, Trillina, and Hofkerina. These are usually found associated with the more widely ranging large forms as Amphistegina, Operculina, Carpenteria, Gypsina, and Planorbulinella, there being definitely restricted species of the last two genera. These restricted species are found in friable polyzoal limestones and marls, and in hard limestones. In this Bulletin, no attempt is made at systematic descriptions of the foraminifera. It is more in the nature of an attempt to help the field geologist to locate himself in the Tertiary sections throughout Victoria.

Natural Hazards - Australian Flood Studies Database

A Flood Study is a comprehensive technical investigation of flood behaviour. It defines the nature and extent of flooding across the landscape by providing information such as the extent, level and velocity of floodwaters and the distribution of flood flows.
The Australian Flood Studies Database provides metadata on Australian flood studies and information on flood risk. It contains general information for all studies, including the study location, date, commissioning organisation and lead consultant. Additional information reflects the scope of each flood study. The types of additional information which may be included fall into nine categories, including hydrological estimates, hydraulic modelling, damage assessments, terrain survey, survey of building floor levels, maps of inundation extent, maps of flood hazard, flood mitigation strategies and post flood information. Where available, attachments of the flood studies and associated reports are included. 
The ownership of each Flood Study remains with the commissioning organisation and/or author as indicated with each study, and users of the database should refer to the reports themselves to determine any constraints in their usage.
The database uses boundary datasets that are published by other agencies:

Kidson Area A, WA, 1996 (P771), 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 Kidson Areas A &amp; B, WA, 1996 survey were acquired in 1996 by the WA Government, and consisted of 128005 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.

Petrology and platinum-group-element geochemistry of Archaean layered mafic-ultramafic intrusions, west Pilbara Block, Western Australia

In a group of Archaean, layered, mafic-ultramafic
 intrusions in the west Pilbara Block, Western Australia, the Munni Munni Complex (2925 Ma) 
 contains a substantial resource of PGEs (20-30 Mt @ 2.9 ppm Pt + Pd + Au) and other intrusions 
 contain subeconomic resources of Ni and Cu. Contrasting PGE distribution patterns within the group 
 indicate that the timing and mechanism of S-saturation were critical for the formation of PGE-enriched 
 sulphide units. Generally, overlying mafic units are thicker than the rhythmically layered ultramafic 
 components. Olivine and clinopyroxene were usually the first minerals to crystallise and cumulus 
 orthopyroxene is restricted to the upper parts of the ultramafic zones. Chromium partitioned into early 
 crystallising clinopyroxene, thus downgrading the potential for PGE-chromite associations. The parent 
 magmas were probably siliceous, high-Mg basalts of Aldepleted komatiitic affinity. In this study, 
 the variations of PGEs and incompatible trace elements were documented up the entire stratigraphic 
 successions.  In the Munni Munni Complex (the intrusion studied in most detail) the PGEsulphide 
 mineralisation is directly below the ultramafic/gabbroic contact and is thought to have resulted 
 from crystal fractionation and mixing of S-undersaturated and S-saturated magmas; as in the Great 
 Dyke of Zimbabwe, it does not occur at or near the base of clearly defined cyclic units. The other 
 (smaller,mainly sheet-like) intrusions studied typically contain basal segregations of PGE-poor 
 Ni-Cu sulphides; the magmas were generally S-saturated early in their evolution and there was no 
 PGE enrichment at higher levels. In exploration, variations in the ratios of precious metals and 
 the trends of the incompatible lithophile and chalcophile elements should be used in association 
 with field and mineralogical evidence to indicate potential PGE-enrichment processes, such as
  S-saturation, crustal contamination, crystal fractionation, magma mixing, and/or hydrothermal 
  remobilisation.

Petrography and seal capacity of a diamictite from Waukarlycarly-1: Report for Geoscience Australia

This report presents the results of scanning electron microscopy (SEM) and mercury porosimetry analyses on 1 whole core sample from the GSWA Waukarlycarly 1 stratigraphic well drilled in the Canning Basin. The well was drilled as part of a co-funded collaboration between Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA) aimed at gathering new subsurface data on the potential mineral, energy and groundwater resources in the southern Canning Basin. The collaboration resulted in the acquisition of the Kidson Deep Crustal Seismic Reflection Survey in 2018; and the drilling of deep stratigraphic well GSWA Waukarlycarly 1, located along the Kidson Sub-basin seismic line within the Waukarlycarly Embayment in 2019 (Figure 1).
GSWA Waukarlycarly 1 reached a total depth of 2680.53 m at the end of November 2019 and was continuously cored through the entire Canning Basin stratigraphy. Coring was complemented by the acquisition of a standard suite of wireline logs and a vertical seismic profile. The work presented in this report constitutes part of the post well data acquisition. The purpose of the SEM analysis was to determine mineralogy and textural relationships between grains, verify the presence of organic material at the micro-scale, document i) the presence of diagenetic alterations to the detrital mineral assemblage and ii) eventual distribution of visible pores. Additionally, mercury injection capillary pressure porosimetry (MICP) was used to assess interconnected porosityand pore size distribution.

This GSWA Merredin Bruce Rock North potassium grid geodetic is an airborne-derived radiometric potassium window countrate grid for the Merredin-Bruce Rock, WA, 1997 survey. 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 GSWA Merredin Bruce Rock North potassium grid geodetic radiometric potassium window countrate grid has a cell size of 0.0005 degrees (approximately 51m). The data are in units of counts per second (cps). The data used to produce this grid was acquired in 1997 by the WA Government, and consisted of 27533 line-kilometres of data at 150m line spacing and 50m terrain clearance.

Wetlands Insight Tool: Characterising the Surface Water and Vegetation Cover Dynamics of Individual Wetlands Using Multidecadal Landsat Satellite Data

Wetlands around the world provide crucial ecosystem services and are under increasing pressure from multiple sources including climate change, changing flow and flooding regimes, and encroaching human populations. The Landsat satellite imagery archive provides a unique observational record of how wetlands have responded to these impacts during the last three decades. Information stored within this archive has historically been difficult to access due to its petabyte-scale and the challenges in converting Earth observation data into biophysical measurements that can be interpreted by wetland ecologists and catchment managers. This paper introduces the Wetlands Insight Tool (WIT), a workflow that generates WIT plots that present a multidecadal view of the biophysical cover types contained within individual Australian wetlands. The WIT workflow summarises Earth observation data over 35 years at 30 m resolution within a user-defined wetland boundary to produce a time-series plot (WIT plot) of the percentage of the wetland covered by open water, areas of water mixed with vegetation (‘wet’), green vegetation, dry vegetation, and bare soil. We compare these WIT plots with documented changes that have occurred in floodplain shrublands, alpine peat wetlands, and lacustrine and palustrine wetlands, demonstrating the power of satellite observations to supplement ground-based data collection in a diverse range of wetland types. The use of WIT plots to observe and manage wetlands enables improved evidence-based decision making.
