Advanced CO2 Geological Storage Sites 2030 (2021)

This dataset shows the spatial locations of potential CO2 storage regions that are at an advanced stage of characterisation and/or development and are expected to be operating by 2030. The areas considered to be at an advanced stage are parts of the Cooper Basin in central Australia, a portion of the Surat Basin (Queensland) and the offshore Gippsland Basin (Victoria), where the CarbonNet Project is currently at an advanced stage of development. We have also considered the offshore Barrow Sub-basin (part of the Northern Carnarvon Basin) (WA), where the Gorgon CO2 Injection Project is occurring on Barrow Island. An earlier version of this dataset was originally published in Feitz et al (2019) “Prospective hydrogen production regions of Australia” and the current version has been updated to include a portion of the offshore Petrel Sub-basin (Bonaparte Basin), offshore Northern Territory. This dataset is used in Geoscience Australia's Hydrogen Economic Fairways Tool (HEFT), which is available for public use at the AusH2 website or at ga.gov.au/heft.

Australian Mineral Blocks 2020 - Geodatabase

Australian Mineral Blocks (2020) - Aligned with the current Australian Maritime Boundary Dataset (AMB2020).
ESRI Geodatabase. 
Available for download as GDA94 or GDA2020.
The dataset was created by Geoscience Australia using the framework described in Section 17 of the Offshore Minerals Act 1994.
The international, scheduled areas and coastal waters used in this dataset are those found in the current Australian Maritime Boundary Dataset 2020 (AMB2020).  The 2020 release has been updated to reflect the 2018 Timor Sea Treaty.
The dataset is comprised of both polygons and points created to very high precision, accurate to within millimetres.
The blocks have been cut by Australia's international boundaries, the scheduled areas and the coastal waters. Each block is assigned a polygon, including partial blocks. All blocks are titled with their block ID, and a list of vertices that make up the blocks. Each vertex of the dataset is also replicated as a discrete point in the points dataset.
The design of the dataset allows for the exact location of every vertex to be known to millimetre precision. The corner coordinates of blocks are now defined to a high precision, and can be found by querying the appropriate point.
The blocks are attributed with fields containing information on:
    Block ID
    Parent 1 Million Mapsheet
    Offshore Area
    Epoch of the boundaries used to cut the data  AMB2014
    Datum
    Origin of the mapsheet in AGD66
    The position of all vertices in the block
    The number of vertices in the block
    The area of the block in acres
    The area of the block in hectares
The calculation used to find the area of the blocks is estimated to be precise to better than 1%. This is considered to be sufficient as under the permit and licensing arrangements in the Offshore Minerals Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference.

North Central Tasmania elevation grid (north) geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This North Central Tasmania elevation grid (north) geodetic is elevation data for the North Central Tasmania, Tas, 1999. This survey was acquired under the project No. 699 for the geological survey of TAS. The grid has a cell size of 0.00042 degrees (approximately 41m).  This grid contains the ground elevation relative to the geoid for the North Central Tasmania, Tas, 1999. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

GSNSW Exploration NSW Area U Southern Peel dose rate grid geodetic

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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSNSW Exploration NSW Area U Southern Peel dose rate grid geodetic has a cell size of 0.00048 degrees (approximately 50m) and shows the terrestrial dose rate of the NSW DMR, Discovery 2000, AREA U, SOUTHERN PEEL, NSW 2001. The data used to produce this grid was acquired in 2001 by the NSW Government, and consisted of 31584 line-kilometres of data at 250m line spacing and 80m terrain clearance.

Use of 87Sr/86Sr ratios in groundwater to assess inter-aquifer connectivity

The Keep River area in the East Kimberley, northern Australia, is underlain by aquifers hosted in both unconsolidated Cenozoic sediments, and Permo-Carboniferous sandstone bedrock. The Permo-Carboniferous sandstone aquifer is in places overlain by the Cenozoic aquifer, and in other areas is exposed at surface, with hydraulic gradients between the aquifers indicating vertical flow from the Permo-Carboniferous sandstone into the Cenozoic. Connectivity between these two aquifers is important to proposals to increase development of irrigated agriculture. 
Water quality in both aquifers appears to be controlled by the same processes, with extremely fresh (TDS &lt; 100 mg/L) water occurring close to recharge areas, and saline (TDS &gt; 30,000 mg/L) water in both aquifers close to the coast. This makes the identification of connectivity from major ion chemistry difficult. We present new groundwater chemistry and monitoring data for the Keep River area, and describe the use of 87Sr/86Sr ratios in groundwater to identify areas of possible inter-aquifer connectivity.
Strontium isotope ratios (87Sr/86Sr) provide an additional method of characterising groundwater. Production of 87Sr occurs through radioactive decay of 87Rb which has a half-life of ~ 4.7 Ga. On the timescales typical of groundwater residence times, 87Sr/86Sr of aquifer material can be treated as constant. The 87Sr/86Sr ratio of groundwater changes over time as a result of equilibration between groundwater and the aquifer matrix. In sedimentary rocks and sediments 87Sr/86Sr will be controlled by the provenance of sediments and is usually dominated by feldspars in siliciclastic lithologies. 
Highly evolved groundwater samples, identified by elevated Si in solution, show distinctly different 87Sr/86Sr ratios between the Cenozoic and Permo-Carboniferous aquifers, which may indicate limited vertical flow between the aquifers. Further work will focus on the spatial distribution of variations in 87Sr/86Sr ratios.

Sentinel-2 Near Real-Time Surface Reflectance

The Surface Reflectance product has been corrected to account for variations caused by atmospheric properties, sun position and sensor view angle at time of image capture. These corrections have been applied to all satellite imagery in the Sentinel-2 archive. This is undertaken to allow comparison of imagery acquired at different times, by different sensors, in different seasons and in different geographic locations. These products also indicate where the imagery has been affected by cloud or cloud shadow, contains missing data or has been affected in other ways. Near Real-Time capability provides analysis-ready data that is processed on receipt using best-available ancillary information to provide atmospheric corrections.

Wollongong Landslides: Hazard Modelling and Risk Assessment

Landslide in Australia, for the most part, is not seen as a major threat to our urban communities. However, this general belief is far from the reality of the situation. Our history of landsliding is highlighted with devastating events such: 
Thredbo landslide, July 1997; 18 people killed
Gracetown cliff collapse, September 1996; 9 people killed.

In Australia, there have been 37 recorded fatal landslides since 1842, which have been responsible for the deaths of 83 people. It is almost certain that these statistics are incomplete and that the number of fatalities is much higher.
The city of Wollongong is on Australia's east coast, approximately 80 km south of
Sydney. Today, Wollongong has one of the highest population growth rates in NSW.
Since 1887, 478 landslides have been recorded at Wollongong, at least two people
have been killed, more than 200 buildings destroyed or damaged and there is constant
disruption to infrastructure and services. It is estimated that between 1989 and 1996,
the cost of landsliding to railway infrastructure alone in Wollongong was A$25 million
annually. Extensive areas of the Wollongong hinterland are prone to landsliding from
heavy rainfall events, as demonstrated by the August 1998 storms. During this event,
148 landslides were reported and access to the city was cut by landslides and
floodwaters for up to 24 hours. It is estimated that up to A$100 million dollars damage
resulted.
