Geoscience Australia Landsat Tasseled Cap Percentiles Collection 3

Tasseled Cap percentiles provide an annual summary of how the environment has varied through a year. The Tasseled Cap percentiles provide the upper, lower and middle conditions as described by the 90th, 10th and 50th percentiles respectively, of greenness, wetness and brightness across the landscape.

These percentiles are intended for use as inputs into classification algorithms to identify such environmental features as wetlands and groundwater dependent ecosystems, and characterise salt flats, clay pans, salt lakes and coastal land forms.

AUSGeoid98 v.1.0 data files: Mount Liebig (sf52-16)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Green steel supply chain options between Australia and Japan

Output Type: Exploring for the Future Extended Abstract

Short Abstract: The global push towards decarbonisation may disrupt existing steelmaking supply chains. While this presents opportunities for Australia, it remains an open question as to what the country’s role should be within new international value chains. Here, we examine green steel production and export strategies between Australia and Japan, comparing different exports from raw material feedstocks to end products. We assess five scenarios in 2030, involving Australian exports of green steel, hot briquetted iron, green ammonia, liquid hydrogen, and/or iron ore pellets. The export of iron ore pellets for Japanese processing using offshore wind is most expensive (~AU$1500/tonne). Although, direct steel production is most economical (~AU$1000/tonne) due to lower energy costs from holistic system optimisation, exporting hot-briquetted iron or HBI (~AU$1032/tonne) balances Australia’s resources with Japan’s steel manufacturing expertise. The liquid hydrogen and ammonia pathways incur substantial energy losses from conversion and reconversion processes, making them less competitive. Trade partnerships across the value chain enhance sustainability and economic feasibility of international green steel manufacturing.

Summary of results. Joint NTGS-GA geochronology project: Aileron Province, July 2016-June 2017

This Record presents data collected between July 2016 and June 2017 as part of the ongoing Northern Territory Geological Survey–Geoscience Australia (NTGS–GA) SHRIMP geochronology project under the National Collaborative Framework (NCF) agreement. Two new U–Pb SHRIMP zircon  geochronological results derived from two samples from the Aileron Province in the Northern Territory are presented herein.
A sample of Wabudali Granite (NTGS MT16MVM008) was collected from the walls of an abandoned tungsten working at Singleton Bore/Wilson’s Find, located 2.5 km east of a station track connecting Singleton Bore with Buger Creek Bore on the southernmost extent of Chilla1. At the sample locality, a fractionated evolved phase of the Wabudali Granite hosts veined tungsten mineralisation interpreted to be genetically related to granite emplacement. Concordant zircons from this sample yielded a magmatic crystallisation age of 1586 ± 4 Ma, and inheritance between ca 2384 Ma and ca 1772 Ma. The interpreted ca 1586 Ma magmatic crystallisation age for the Wabudali Granite provides a maximum age for tungsten and copper mineralisation hosted in more evolved pegmatite phases of the Wabudali Granite at the Singleton Bore/Wilson’s Find tungsten prospect.
A sample of leucogranite (NTGS TB16MVM004) was collected from a rare exposure at Camel Creek, 100 m west from a track that connects Snake Tank and Junction Bore on Tarlton Downs Station, in south-central Tarlton. Locally, malachite in quartz veins cross-cut the leucogranite; the leucogranite also shows evidence for pervasive hematite and chlorite alteration. Concordant zircons from unaltered leucogranite yielded a magmatic crystallisation age of 1741 ± 12 Ma, and inheritance between ca 3068 Ma and ca 1778 Ma. The interpreted magmatic crystallisation age for this sample is within the range of crystallisation ages (ca 1.76–1.74 Ga) reported for the Mount Tietkens Granite Complex (Kruse et al 2002). The crystallisation age for this sample provides a maximum age constraint for veined copper mineralisation hosted in the sampled granite in the Camel Creek area.

Outer Darwin Harbour Marine Survey 2015: Grain size data of seabed sediments.

This resource contains surface sediment data for Outer Darwin Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Land Resource Management) during the period from 28 May and 23 June 2015 on the RV Solander (survey SOL6187/GA0351). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Land Resource Management, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps that underpin marine resource management decisions. The specific objectives of the survey were to:

1.   Obtain high resolution geophysical (bathymetry) data for outer Darwin Harbour, including Shoal Bay;
2.   Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for outer Darwin Harbour, including Shoal Bay; and 
3.   Collect tidal data for the survey area.

Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; physical samples of seabed sediments, underwater photography and video of grab sample locations and oceanographic information including tidal data and sound velocity profiles.

Yilgarn Block (Hyden), WA, 1976 (P439), 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 Yilgarn Block (Hyden), WA, 1976 survey were acquired in 1976 by the WA Government, and consisted of 12173 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.
