On Australina Clarke - and its junior synonyms Lissatrypa, Lissatrypoidea, and Tyrothyris (Silurian-Devonian Brachiopoda)

The Silurian-Devonian lissatrypid genera Lissatrypa, Tyrothyris and Lissatrypoidea are shown to be congeneric, and junior synonyms of Australina Clarke, 1913; the tiny naviculate Nanospira is treated as a subgenus. Meifodia differs in the shape of the ventral median platform and the orientation of the spiraIia. Gracianella lissumbra differs only in lacking inner hinge plates, and (contra Johnson and Boucot, 1972) is considered most unlikely to be either ancestral to the Carinatininae, or closely related to Dnestrina, which is an anoplotheciid.

Wiso Basin trav01, NT, 2000 (P1015), 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 Wiso Basin, NT, 2000 survey were acquired in 2000 by the NT Government, and consisted of 113520 line-kilometres of data at 400m line spacing and 80m 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.

Antarctic Geodesy Field Report 2008-2009

During the 2008-09 Antarctic summer, Geoscience Australia surveyors undertook fieldwork at the Davis, Casey, Mawson and Macquarie Island research stations, as well as several remote sites in Eastern Antarctica.  At each of the research stations, upgrades and local deformation monitoring surveys were performed at the continuously operating reference stations, which form part of the Australian Antarctic GNSS Network and the Australian Regional GNSS Network.  Remote GPS sites in the Grove Mountains, Bunger Hills and Wilson Bluff were visited for equipment upgrades and data retrieval.  Additional surveys were undertaken which focussed on enhancing the spatial infrastructure around the Larsemann Hills, Rauer Group, Vestfold Hills and Davis station. Support was also provided to a number of different Australian Antarctic Division projects and university research groups.

Characterising groundwater dependent ecosystems of the Upper Darling floodplain using optical and radar remote sensing

Groundwater is critical to the survival of a range of ecosystems in Australia through provision of a direct source of water to plants with suitable root systems, and through discharge into surface water systems. Effectively managing groundwater dependent ecosystems (GDEs) alongside other water demands requires the ability to identify, characterise, and monitor vegetation condition.&nbsp;&nbsp;
As part of the Exploring for the Future Upper Darling Floodplain (UDF) groundwater project in western New South Wales, we present results from a study testing the suitability of two novel methods (a) recently available tasselled cap percentile products with national coverage through Digital Earth Australia, and (b) dry-conditions interferometric radar (InSAR) coherence images for mapping vegetation that is potentially groundwater dependent. &nbsp;
&nbsp;
A combination of greenness and wetness 10th percentile tasselled cap products delineated terrestrial and aquatic GDEs with greater accuracy than existing regional ecosystem mapping, demonstrating the utility of these products for GDE identification. These results suggest the tasselled cap products can be used to support and refine the existing GDE mapping for this region, and further testing of their suitability and application for other regions is warranted.&nbsp;&nbsp;
&nbsp;
The InSAR coherence images produced good agreement with the Bureau of Meteorology national GDE Atlas for areas of high probability of groundwater dependence. Although data availability and technical expertise currently lags behind optical imagery products, if research continues to show good performance in mapping potential GDEs and other applications, InSAR could become an important line of evidence within multi-dataset investigations.&nbsp;&nbsp;
&nbsp;
Key next steps for improving the utility of these techniques &nbsp;are (a) comparison with vegetation condition data, and (b) further assessment of the likelihood of groundwater dependence through assessing relationships between vegetation condition and groundwater, surface water, and soil moisture availability.&nbsp;
&nbsp;

Murray Basin (Hay, Narrandera, Deniliquin, Jerilderie), NSW, 1987 (GSV0377) (P546), 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.

Meekatharra 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.

Guide to Using the Australian Archean Mafic-Ultramafic Magmatic Events Map

Geoscience Australia has released two web-based map sheets (GeoCat 69347) that show the continental extent and age relationships of Archean mafic and ultramafic rocks and associated mineral deposits throughout Australia. Geoscience Australia Record 2009/41 is a user guide which compiles all the geological and geochronological data that underpins the information portrayed on these two new map sheets.
The Archean eon (~4000 million years to 2500 million years) represents an early part of Earth's history that is noteworthy for the occurrence of unusual olivine-rich ultramafic rocks called komatiites which contain world-class deposits of nickel sulphides. 
Archean mafic and ultramafic igneous rocks with reliable crystallisation ages in Australia are confined to the older crustal components in Western Australia and South Australia. In this study, twenty-six Archean Magmatic Events (AME) ranging in age from the Eoarchean ~3730 Ma (AME 1) to the late Neoarchean ~2520 Ma (AME 26) were identified. This mafic-ultramafic magmatic event series is based on several hundred published age measurements, of which over 95 per cent are derived from recent Uranium-Lead dating of zircon and baddeleyite. 
The new map sheets, when used in association with the `Australian Proterozoic Mafic-Ultramafic Magmatic Events' map published in 2008 (GeoCat 66114; GA Record 2008/15: GeoCat 66624), summarise the temporal and spatial evolution of Precambrian mafic-ultramafic magmatism in Australia. These maps provide a national framework for investigating under-explored and potentially mineralised environments, and assessing the role of mafic-ultramafic magmatism in the development of the Australian continent. The maps will be of interest to explorers searching for nickel, platinum-group elements, chromium, titanium, vanadium, and cobalt.
