Nabberu North, W.A. airborne geophysical survey, 1996: operations report

As part of the National Geoscience Mapping Accord the Australian Geological Survey
Organisation flew an airborne geophysical survey of 25 394 line km over the northern half of
the Nabberu 1:250 000 Sheet of WA from 19 April to 14 March 1996. The flight line
direction was north-south and the line spacing was 400 m. Flying height was at an altitude of
80m above ground level.
The southern half of the Nabberu 1:250 00 Sheet was flown concurrently under of an AGSO
contract. Data from both suveys were merged to produce a consistent dataset for the whole
Sheet area. This report concentrates on the details regarding the survey operations and
processing of the Nabberu North survey.
The total magnetic intensity, gamma-ray spectrometric and digital elevation model data which
were collected during both surveys, have been processed and are available for purchase, in
both digital (point located data and gridded) and map form, from the Australian Geological Survey Organisation. Colour and greyscale pixel image maps are also available.

Melbourne CBD Case Study: URM Retrofit Effectiveness in Avoiding Mass Casualties

Earthquakes occur without warning and human mobility during strong shaking is difficult. This has implications for casualty outcomes from such rapid onset events.  Unreinforced masonry (URM) in particular presents a great risk in the high pedestrian exposure precincts of major cities.  Surveys of major Australian cities have indicated that almost half of the central business district (CBD) buildings by number are of older URM construction and have elements that could fall onto pedestrians in a major shake.  With a focus on the greater CBD of Melbourne, this risk and mitigation options for it have been studied.
In a case study undertaken as part of the Bushfire and Natural Hazards CRC (BNHCRC), the casualties, damage and broader economic consequences of a major earthquake in central Melbourne have been modelled.  This research directly utilised BNHCRC vulnerability research on URM by the authors and separate work by Geoscience Australia on modelling human exposure in a major business precinct.  Through a virtual retrofit of the high risk URM buildings the benefits of retrofit were demonstrated. In particular, the prioritising of areas of high human exposure in a manner similar to that being used in New Zealand was found to achieve greater reductions of injuries.

Forecasting the Impacts of Severe Weather: A Review

National meteorological and hydrological services (NMHSs) provide severe weather warning information to inform decision-making by emergency management (EM) services and to allow communities to take defensive and mitigation action prior to and during severe weather events. Globally, warning information issued by NMHSs varies widely from solely hazard-based to impact-based forecasting encompassing the exposure and vulnerability of communities to severe weather. The most advanced of these systems explicitly and quantitatively model the impacts of hazards on sectors of interest. Incorporating impact information into severe weather warnings contextualises and personalises the warning information, increasing the likelihood that individuals and communities will take preparatory action. This paper reviews a selection of current efforts towards severe weather warnings and impact forecasting capabilities globally and highlights uncertainties that currently limit forecasts and modelling of multi-hazard events.

Noble Gas Isotopes of Natural Gases from the Shipwreck Trough, Offshore Otway Basin, Victoria, Australia - Data Release

A regional hydrocarbon prospectivity assessment has been undertaken of the offshore Otway Basin by the Offshore Energy Systems Section. This program was designed to produce pre-competitive information to assist with the evaluation of the hydrocarbon resource potential of the offshore Otway Basin and attract exploration investment to Australia. The inboard part of the basin is an established hydrocarbon province with onshore and shallow-water offshore discoveries, whereas the outboard deep-water region, where water depths range from 500 to 6300&nbsp;m, is comparatively underexplored and considered a frontier area.

As part of this program, molecular and noble gas isotopic analyses were undertaken by Smart Gas Sciences, under contract to Geoscience Australia on available gas samples from the Waarre Formation in the Shipwreck Trough in the offshore eastern Otway Basin, with data from these analyses being released in this report. This report provides additional compositional information for gases in the Waarre Formation reservoirs and builds on previously established gas-gas correlations and gas-oil correlations. Noble gas isotopic data can be used in conjunction with carbon and hydrogen isotopic data to determine the origin of both inorganic and organic (hydrocarbon) gases. This information can be used in future geological programs to determine the source and distribution of hydrogen and helium in natural gases and support acreage releases by the Australian Government.

Australian Marine Physical Environmental Data - Descriptions and Metadata

This report provides detailed metadata for the 37 marine physical environmental variables that were collated or specifically generated by the Marine Biodiversity Hub, which is part of the Commonwealth Environment Research Facilities Program. The work was done at Geoscience Australia and the Marine and Atmospheric Division of CSIRO. The data are required for use in the Hub's surrogacy and predictive modelling research. Bathymetry, geomorphology, seabed sediment and seabed exposure data were produced by Geoscience Australia. Bottom-water and surface-water parameters were produced by CSIRO. For each variable there is a general description, comprehensive metadata and a distribution map. All data were transformed to a common datum, WGS84, and converted to a grid with a cell size of 0.01 degrees. The metadata reports conform to ANZLIC standards.
The data fall into five categories:
1. Bathymetry and geomorphology, derived from the 250 m resolution National Bathymetry Grid at Geoscience Australia;
2. Seabed sediments, derived from the MARS database at Geoscience Australia;
3. Seabed exposure, produced from the output of a seabed shear stress model, GEOMACS, at Geoscience Australia;
4. Bottom-water nutrients and temperature, extracted from the CARS database at CSIRO;
5. Surface-water parameters, derived from satellite images at CSIRO.

Timing of Iron Oxide Cu-Au-(U) Hydrothermal Activity and Nd Isotope Constraints on Metal Sources in the Gawler Craton, South Australia

The eastern Gawler craton hosts Australia's premier uranium-bearing iron oxide copper-gold (IOCG) belt, the &gt;500-km-long Olympic Cu-Au-(U) province. In addition to the Olympic Dam Cu-U-Au and Prominent Hill Cu-Au deposits, numerous barren and weakly mineralized IOCG prospects are present in the province. New geochronological data for hydrothermal minerals combined with constraints from host-rock ages demonstrate that alteration and associated IOCG mineralization formed between ~1570 and ~1600 Ma in three districts of the province. This IOCG hydrothermal activity temporally overlaps with magmatism of the Hiltaba Suite and Gawler Range Volcanics. Titanites in paragenetically early magnetite-bearing alteration in the Olympic Dam and Prominent Hill districts yield U-Pb ion probe ages of 1576 Â± 5 and 1567 Â± 10 Ma, respectively. Molybdenite in veins crosscutting magnetite-biotite and albitic alteration in the Moonta-Wallaroo district have Re-Os ages of 1574 Â± 6 and 1599 Â± 6 Ma, respectively. These represent minimum ages of the IOCG alteration assemblages in this district. A muscovite 40Ar/39Ar age of 1575 Â± 11 Ma provides a minimum age of paragenetically later hematitic alteration in the Olympic Dam district. Neodymium isotope compositions were determined for 44 whole-rock samples from barren and weakly mineralized Cu-Au prospects and host rocks in the Olympic Dam and Prominent Hill districts. The new geochronological framework enables comparison of the Nd isotope data across two IOCG districts at the time of formation of the Olympic Dam deposit (ca. 1590 Ma). Magnetite-rich weakly Cu-mineralized alteration from five prospects yields a relatively narrow range of {varepsilon}Nd(1590) values of -5.8 to -4.1. Both hematite- and magnetite-rich alteration yield generally similar {varepsilon}Nd(1590) values that match values from fresh and weakly altered Paleoproterozoic metasedimentary and metagranitic rocks (-6.6 to -3.5) as well as from most felsic Hiltaba Suite intrusions and Gawler Range Volcanics in the eastern Gawler craton (ca. -6 to -4). These data are consistent with crustal sources for REE and, by implication, for associated copper in the barren and weakly mineralized prospects. Mineralization and alteration in these minor IOCG systems can be geochemically discriminated from the giant Olympic Dam deposit, where greater inputs of mantle-derived REE and other ore components are evident.
