The Cocos (Keeling) Islands Geographic Information System (CocosGIS) is a collection of spatial data, viewing and analysis tools dealing with the Cocos (Keeling) Islands. The data include orthophotography, topographic, cultural and environmental features both of the islands and the ocean immediately surrounding them.

The Cocos (Keeling) Islands Geographic Information System (CocosGIS) is a collection of spatial data, viewing and analysis tools dealing with the Cocos (Keeling) Islands. The data include orthophotography, topographic, cultural and environmental features both of the islands and the ocean immediately surrounding them. Compilation of data and its organisation into a GIS together with documentation was undertaken by the Australian Geological Survey Organisation (AGSO) at the request of the Territories Office, Department of Transport and Regional Services (DOTRS). The data are presented in both ESRI ArcView and ArcExplorer projects. The ArcView projects require a licensed copy of ArcView. ArcExplorer is a free viewer and is distributed with the Cocos GIS CD-ROM. Data are stored as ESRI shapefiles and therefore readily useable with most modern GIS applications. Data were received from a variety of custodians and in many cases had no accompanying documentation. Lack of documentation made it increasingly difficult for AGSO with interpretation, translation and documentation of data. AGSO has attempted to include metadata for all datasets to ANZLIC core metadata standards, but the value of this is limited by the poor initial documentation. In addition to limited documentation, many datasets had inconsistent spatial accuracy. The CocosGIS comprises four main CD-ROMs with additional CD-ROMs containing full-colour orthophotography. A hard-copy user guide is distributed with the main CD-ROM set.

The Cocos Keeling Islands Geographic Information System (CocosGIS) is a collection of spatial data, viewing & analysis tools dealing with the Cocos Keeling Islands. The data includes orthophotography, topography, culture and envrionment features of both of the islands and the areas immediately surrounding them.

This web service shows the spatial locations of potential CO2 storage sites that are at an advanced stage of characterisation and/or development. 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), the offshore Gippsland Basin (Victoria), where the CarbonNet Project is currently at an advanced stage of development and the Petrel Sub-basin. This service will be presented in the AusH2 Portal.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the north Bowen Basin. This data guide illustrates the current understanding of the distribution of these key resource types within the north Bowen Basin region based on trusted information sources. It provides important contextual information on the north Bowen Basin and where additional details on discovered resources can be found. The north Bowen Basin contains 17 metallic mineral deposits, with the majority containing gold. The basin also contains 152 thermal and metallurgical coal deposits. Most coal deposits contain metallurgical coal. This basin contains most of Queensland’s metallurgical coal resources, although many of the deposits supply a mix of thermal and metallurgical coal (Blake et al., 2018). The north Bowen Basin hosts very large coal tonnages, with known black coal resources of approximately 47 billion tonnes. Significant hydrocarbon resources are known to exist in the basin, the majority being coal seam gas (CSG). The basin contains more limited reserves and resources of conventional oil and gas and oil shale. At this time, there are no active or planned CCS projects in the basin.

Internationally, the number of carbon capture and storage (CCS) projects has been increasing with more than 61 new CCS facilities added to operations around the globe in 2022, including six projects in Australia (GCCSI, 2022). The extraction of reservoir fluid will be an essential component of the CCS workflow for some of projects in order to manage reservoir pressure variations and optimise the subsurface storage space. While we refer to reservoir fluid as brine throughout this paper for simplicity, reservoir fluids can range from brackish to more saline (briny) water. Brine management requires early planning, as it has implications for the project design and cost, and can even unlock new geological storage space in optimal locations. Beneficial use and disposal options for brine produced as a result of carbon dioxide (CO2) storage has been considered at a regional or national scale around the world, but not yet in Australia. For example, it may be possible to harvest energy, water, and mineral resources from extracted brine. Here, we consider how experiences in brine management across other Australian industries can be transferred to domestic CCS projects.

Publicly available geological data in the north Bowen Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This web service summarises potential mineral, natural hydrogen, coal and carbon dioxide geological storage in the north Bowen Basin region.

In April 2015 Geoscience Australia (GA) acquired 908 km (full-fold) Gippsland Southern Margin Infill 2D Seismic data using Gardline's M/V Duke. The survey is designed to better resolve the Foster Fault System and provide better integration between the GDPI10 survey and the existing surveys in the central deep. The data underwent pre-stack depth migration with a deghosting algorithm during processing. The dataset includes intermediate processing products as well as final preSTM and preSDM and associated velocities.
