Under the Community Stream Sampling and Salinity Mapping Project, the Australian Government through the Department of Agriculture, Fisheries and Forestry and the Department of Environment and Heritage, acting through Bureau of Rural Sciences, funded an airborne electromagnetic (AEM) survey to provide information in relation to land use questions in selected areas along the River Murray Corridor (RMC). The proposed study areas and major land use issues were identified by the RMC Reference Group at its inception meeting on 26th July, 2006. This report has been prepared to facilitate recommendations on the Lindsay-Wallpolla study area. The work was developed in consultation with the RMC Technical Working Group (TWG) to provide a basis for the RMC Reference Group and other stake holders to understand the value and application of AEM data to the study area. This understanding, combined with the Reference Group's assessment of the final results and taking in account policy and land management issues, will enable the Reference Group to make recommendations to the Australian Government.

Describes the Western Water Study (Wiluraratja kapi), a 3-year AGSO project to assess groundwater resources and identify regional water issues in remote Aboriginal Communities in the Northern Territory.

The purpose of this Record is to document the written material issued at the Groundwater School held 29 March - 9 April 1965 in Adelaide. Record 1965/85 deals with the organisation, syllabus, and general scope of the School and it is not necessary to repeat these aspects in this record. The material is issued in two parts: Part 1: Hydrogeology, Geophysics, Hydraulics, and Pumping Tests. Part 2: Drilling, Bore Construction, Chemistry of Groundwater, Utilisation. No attempt was made to edit the material which was written by the lecturer in most cases as lecture notes and not for publication.

This Geocat record is a CD of presentations delivered as part of the 4th Technical Advisory Group workshop for the Palaeovalley Groundwater Project. The workshop was held in Canberra at Geoscience Australia on 5 and 6 April 2011 and involved ~20 people including GA staff and invited guests from state government water resource and geological survey organisations in SA, NT and WA. The CD has been compiled as a record of the workshop and will be delivered to the workshop participants as a record of the event.

The geological storage of carbon dioxide (CO2) is the process whereby CO2 captured from power plants or other industrial facilities is transported by pipeline to a suitable location and then injected under pressure into a deep geological reservoir formation, where it remains permanently trapped and prevented from entering the atmosphere. The processes by which it is retained in the subsurface are generally those that have trapped oil, gas and naturally generated CO2 for millions of years. The geological formations that can be utilised for this trapping have the same characteristics as those that are able to act as reservoir rocks for petroleum. They have good porosity and permeability and have an overlying sealing formation, which will prevent the trapped fluids migrating out of the storage reservoir and possibly escaping to the surface. In addition, because of the phase behaviour of CO2, efficient storage requires that they are stored at depths greater than 800 below the surface. Unlike oil and gas, which rely primarily on a three dimensional structural trap to prevent them from ultimately rising to the surface, there are additional trapping mechanisms for CO2. Given a sufficiently long migration path within a formation, CO2 will ultimately be rendered immobile by dissolution into the formation water, residual trapping and potentially, over longer time scales, mineralisation. As groundwaters at these depths are generally saline, this type of storage is often termed deep saline aquifer storage. A recent nationwide review by Commonwealth and State geological surveys, as part of the Carbon Storage Taskforce, rated the suitability of geological basins across Australia for geological storage of CO2. The most geologically suitable basins are the offshore Gippsland and North Perth basins but several onshore basins also rate highly. These include the Eromanga, Cooper, Bowen, Galilee, Surat, Canning and Otway basins. The Victorian Government has recently released area for greenhouse gas storage exploration in the Gippsland Basin and the Queensland Government in the Galilee and Surat basins. The aquifers within these basins provide groundwater for human consumption, agriculture, mining, recreation and groundwater dependent ecosystems. The Surat Basin also contains oil and gas accumulations that are being exploited by the onshore petroleum industry. Understanding the existing the groundwater's chemistry and the connectivity between aquifers in the context of its current use is essential in order to determine whether prospective aquifers could be used for geological storage of CO2 without compromising other activities. The potential risks to groundwater from the potential migration of CO2 and changes to groundwater properties that might be expected will also be discussed. Current data gaps include poor hydrogeochemical data coverage for the deeper aquifers and particularly limited data on trace metals and organics. A comparison with experiences learned from enhanced oil recovery using CO2 in North America and the CO2CRC's pilot CO2 injection project in Western Victoria will illustrate some of the unique differences and opportunities for geological storage of CO2 in Australia.
