The Australia Epoch 1995.0 geomagnetic field chart maps the main geomagnetic field and its secular variation in the Australian region between 1995 and 2000 . The chart is derived from the Australian Geomagnetic Reference Field model (AGRF) of the same epoch. From 1990 to 2005 the AGRF has been updated at five yearly epochs. A main field model is produced for each five yearly epoch, along with a prospective secular variation model to extend the life of the model. The AGRF model represents the Earth's main magnetic field originating from the core and the broad scale crustal field. The AGRF does not model short term variations of the magnetic field with time, such as those caused by solar activity or ionspheric currents. The AGRF is derived from vector magnetic data from ground level, aircraft and satellite surveys as well as the network of geomagnetic observatories and repeat stations run by Geoscience Australia and neighbouring countries. (This chart is now superseded.)

The purposes of this Bulletin are to explain and describe the accompanying 1:10 000 000-scale geological map, to discuss briefly the map's units, and to provide readers and users with a guide to the rapidly expanding literature of Antarctic geology, from which they can obtain more detailed information.

The Australian Offshore Mineral Locations map shows mineral occurrences and deposits within Australia's 200 nautical mile exclusive economic zone and extended continental shelf. Australia will have one of the largest marine jurisdictions in the world (14.4 million square kilometres) if the United Nations Commission on the Limits of the Continental Shelf agrees to Australia's submission on the outer limit of its extended continental shelf. This is greater than Australia's total land area (13.6 million square kilometres), including Antarctica. The Offshore Mineral Locations map sheds light on the mineral prospectivity in this exciting, but poorly known frontier. It should serve also to ensure mineral values are considered in marine planning and decision making. The Australian Offshore Mineral Locations map draws together data from published and unpublished marine research surveys as well as reports from federal and state government records. Mineral locations shown include manganese nodules and crusts, shellsand, construction aggregate, heavy mineral sand, phosphorites, diamonds, tin, copper, gold and coal. Types of mineralisation, some interpreted from limited information, provide an insight into the nature of the depositional settings. Bathymetry shows the variable physiography of the seafloor that surrounds Australia. For the first time it is possible to identify features such as the contextual setting of manganese crusts and nodules on the East Tasman Plateau and South Tasman Rise, and shellsand and cobalt crust on the edge of the Ceduna Terrace where it descends to the South Australian Abyssal Plain. Insets and images on the map show further detail, mineral specimens and operational aspects associated with exploration and recovery of marine minerals. The map is the result of a collaborative project between Geoscience Australia, CSIRO's Wealth from Oceans Flagship and Division of Exploration and Mining, and each of the State and Northern Territory Geological Surveys. The Australian Offshore Mineral Locations data can be viewed online by using Geoscience Australia's Australian Marine Spatial Information System (AMSIS). AMSIS contains more than 80 layers of Australian marine information which can be viewed and integrated with mineral locations data to create maps to meet specific requirements.

The map shows in situ coal resoruces. The resources of brown and black coal depsits are totalled and assigned to basins/regions which host these deposits.
