SA Exploration Initiative, Area P1, 1993 (P722), 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 SA Exploration Initiative, Area P1, 1993 survey were acquired in 1993 by the SA Government, and consisted of 7616 line-kilometres of data at 400m line spacing and 160m 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.

Seafloor Mapping Survey, Windmill Islands and Casey region, Antarctica: GA-0348 Post Survey Report, December 2014 - February 2015

The Casey shallow-water near-shore seabed mapping survey (survey number GA-0348) was conducted as collaboration between Geoscience Australia (GA, Department of Science and Industry), the Royal Australian Navy (RAN, Department of Defence) and the Australian Antarctic Division (AAD, Department of the Environment). The survey was conducted as part of the ongoing AAD program Hydrographic Surveying and Bathymetric Data Acquisition (AAD 3326) and complements a previous charting survey to the Casey region undertaken by RAN and AAD (using the RAN vessel ASV Wyatt Earp) in 2013/14 (also conducted under AAD 3326).
The purpose of the survey was to acquire geophysical, geological and biological data from the seabed environment in the shallow (&lt;250 m) coastal waters adjacent to Casey station. The survey acquisition phase formed the main work program for the Antarctic Geoscience Program and Advice activity as part of the Marine Biodiversity and Antarctic Geoscience (MBAG) Section at Geoscience Australia during 2014/15. 
The shallow water marine environment around Casey station, East Antarctica, is a high use area in the Australian Antarctic Territory, and is frequently visited by the RSV Aurora Australis and smaller vessels conducting scientific research in the area, yet bathymetry data in the area is limited. Additionally, a long-term dive program has revealed the marine habitats in the area host globally significant levels of biodiversity, but this knowledge is geographically restricted in scope (i.e. shallow depths, close to shore). This biodiversity faces pressures from human activities and climate change, yet extensive knowledge gaps remain, limiting efforts to conserve and manage it effectively.

The origin of the earth

It is not possible to consider the formation of the Earth in isolation without reference to the formation of the rest of the solar system.  A brief account is given of the current scientific consensus on that topic, explaining the origin of an inner solar system rocky planet depleted in most of the gaseous and icy components of the original solar nebula.  Volatile element depletion occurred at a very early stage in the nebula, and was probably responsible for the formation of Jupiter before that of the inner planets.  The Earth formed subsequently from accumulation of a hierarchy of planetesimals.  Evidence of these remains in the ancient cratered surfaces and the obliquities (tilts) of most planets.  Earth melting occurred during this process, as well as from the giant Moon-forming impact.  The strange density and chemistry of the Moon are consistent with an origin from the mantle of the impactor.  Core-mantle separation on the Earth was coeval with accretion.  Some speculations are given on the origin of the hydrosphere.

Prospective hydrogen production regions of Australia - geospatial outputs

There is significant interest in Australia, both federally and at the state level, to develop a hydrogen production industry. Australia’s Chief Scientist, Alan Finkel, recently prepared a briefing paper for the COAG Energy Council outlining a road map for hydrogen. It identifies hydrogen has the potential to be a significant source of export revenue for Australia in future years, assist with decarbonising Australia’s economy and could establish Australia as a leader in low emission fuel production. As part of the ongoing investigations into the hydrogen production potential of Australia, Geoscience Australia has been commissioned by the Department of Industry, Innovation and Science to develop heat maps that show areas with high potential for future hydrogen production. The study is technology agnostic, in that it considers hydrogen production via electrolysis using renewable energy sources and also fossil fuel hydrogen coupled with carbon capture and storage (CCS). The heat maps presented in this work are synthesized from the key individual national-scale datasets that are relevant for hydrogen production. In the case of hydrogen from electrolysis, renewable energy potential and the availability of water are the most important factors, with various infrastructural considerations playing a secondary role. In the case of fossil fuel hydrogen, proximity to gas and coal resources, water and availability of carbon storage sites are the important parameters that control the heat maps. In this report we present 5 different heat map scenarios, reflecting different assumptions in the geospatial analysis and also reflecting to some degree the different projected timeframes for hydrogen production. The first three scenarios pertain to renewable energy and hydrogen produced by electrolysis. Differences between the three scenarios depend on whether hydrogen is produced near the coastal areas, where infrastructure and water are not issues or whether hydrogen can be produced in inland areas provided water does become a constraining factor. Assumptions regarding the proximity of a currently connected electrical grid to transport renewable energy also play a large role in the different scenarios. The final two scenarios focus on the potential for fossil fuel hydrogen, coupled with CCS, with the difference between the two scenarios being related to the timeframes for readiness for both fossil fuel production and availability of CO2 storage resources.
This dataset includes the five scenario raster outputs as produced as part of the Prospective hydrogen production regions of Australia report.
