This preliminary report will provide a geochemical and ionic characterisation of groundwater, to determine baseline conditions and, if possible, to distinguish between different aquifers in the Laura basin. The groundwater quality data will be compared against the water quality guidelines for aquatic ecosystem protection, drinking water use, primary industries, use by industry, recreation and aesthetics, and cultural and spiritual values to assess the environmental values of groundwater and the treatment that may be required prior to reuse or discharge.

This map is part of a series which comprises 50 maps which covers the whole of Australia at a scale of 1:1 000 000 (1cm on a map represents 10km on the ground). Each standard map covers an area of 6 degrees longitude by 4 degrees latitude or about 590 kilometres east to west and about 440 kilometres from north to south. These maps depict natural and constructed features including transport infrastructure (roads, railway airports), hydrography, contours, hypsometric and bathymetric layers, localities and some administrative boundaries, making this a useful general reference map.

The cartographic collection of the Doc Fisher Geoscience Library consists of the maps and air photos created or acquired by agency staff since the formation of BMR in 1946. This includes maps produced by agencies which have merged with these over the years, such as AUSLIG. Maps held include: Australian geological map series (1:250,000, 1:100,000 and the 1 mile series); topographic maps produced by NATMAP and its predecessors (1:250,000, 1:100,000 and 1:50,000) - latest editions only; various Australian geochemical, geophysical and other thematic maps; geoscience map series from other countries acquired on an exchange basis, including some with accompanying explanatory notes; Non-series maps acquired by donation or exchange; atlases. The Air photos are predominantly those used for mapping Australia and, to a lesser extent, Papua New Guinea and Antarctica, by BMR/AGSO from the 1940s to the 1980s. Geographical coverage of the sets is not complete, but many individual photos are unique in that they have pin points, overlays or other markings made by teams in the field. The Papua New Guinea photographs in the collection may, in many cases, be the only existing copies. Flight diagrams are also held for many (but not all) sets of air photos. Some other related materials, such as montages of aerial photographs (orthophotos), are also represented in the collection.

An important part of any analytical procedure is to ensure that results are accurate. Geoscience Australia (GA) has been fortunate in that, during the last several years, the use of high-precision CA-ID-TIMS for chronostratigraphy in Australian sedimentary basins has given us access to a substantial selection of precisely dated zircons, which we can use to cross-correlate the SHRIMP and TIMS ages throughout the Phanerozoic. Combined with other double dated samples which have come through our lab, this gives us the ability to plot dozens of doubly dated samples for comparison. Potential sources of disagreement, both geological and analytical, can be investigated using these data. With the exception of two Guadalupian SHRIMP ages, all SHRIMP data presented here was generated in-house on the Geoscience Australia instrument.

Geoscience Australia's workforce is characterised by a diverse range of skills, backgrounds and experiences. Disability is one of the five focus areas of our Inclusive Culture Program, together with gender, Indigenous Australians, age and multicultural diversity. The purpose of this Action Plan is to identify and address barriers which prevent people with disability from joining the workforce and to provide a flexible, accessible and inclusive work environment to enable people with disability, injury or illness to fully participate in the workplace. In order to achieve this, we will take action to build a respectful, inclusive and equitable culture and a flexible and supportive work environment which will benefit all employees.

An application dated 30 July 2013 for verification of a reference standard of measurement under Regulation 12 of the National Measurement Regulations 1999 was received from the Department of Natural Resources and Mines in Queensland, for verification of GDA94 position on their owned or managed station monument. This report documents the processing and analysis of GPS data observed by the Department of Natural Resources and Mines in Queensland during a 7-day period from 23 June 2013 to 29 June 2013 (day of year 174 to 180) for twenty-five CORS stations to satisfy the position verification requirements.
