This map was produced from a hand drawn map showing upwelling around Australia. The hand drawn map is a qualitative summary of published information on upwelling. Upwelling around Australia tends to be intermittent and localised, and thereby make only a relatively modest contribution to total primary production. A range of processes are responsible for the upwelling that does occur. In a system with classical wind-driven upwelling, surface waters are pushed away from the coast by wind-stress to be replaced by cold nutrient-rich waters from the deeper shelf. Such events have usually been observed in summer off southwestern Australia and in parts of the Great Australian Bight when winds are favorable to upwelling. On the NSW coast, significant upwelling only occurs when northerly winds and encroaching eddies from the East Australia Current combine to bring water from the outer-shelf and upper-slope into the surface waters of the inner shelf. A third mechanism applies to some tropical waters, where tidal motions over the steep upper slope generate large internal waves that subsequently break and mix deeper nutrient-rich waters up into the surface layer. This map has been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project. Data depicted is a qualitative summary of published information. Variations in onscreen colour representation or printed reproduction may affect perception of the contained data.

NOTE THIS RECORD HAS BEEN SUPERSEDED BY NESP PROJECT E2 (details below) Cumulative Sound Exposure Levels of shipping traffic in Australian waters was undertaken over a one year period (Sept. 2015 to Oct 2016) within the Australian Exclusive Economic Zone. A proof of concept cumulative ship noise map was developed around Australia using the Perth Canyon source spectra as the source level for different vessel type categories. Sound propagation models were then run cumulatively, integrating the time spent by ships within a grid cell over the one-year period. This record describes the proof of concept map of commercial shipping noise in Australian waters developed under NESP Project C5. Refer to final report (https://www.nespmarine.edu.au/document/quantification-risk-shipping-large-marine-fauna-across-australia-final-report) for full methodology and PDF map. The ship noise modelling demonstrated the potential for using simple and readily accessible transmission models to provide an accurate representation of shipping noise within the marine soundscape. A subsequent high resolution sound exposure map was generated under NESP Project E2. See https://catalogue.aodn.org.au/geonetwork/srv/en/metadata.show?uuid=480847b4-b692-4112-89ff-0dcef75e3b84

The database contains locational and non-locational information for selected dams and storages in Australia. It extends as far as Australia's off-shore limits, but does not include external Territories. Though the database contains information for those dams and storages owned by a public authority, some significant private dams are included.

The source of this information is primarily the databases of the particular controlling authority for each state and, to a lesser extent, maps and publications of State and Federal agencies, in particular, the Australian National Committee on Large Dams (ANCOLD).

The data covers the whole of Australia, both onshore and offshore, between latitude limits -5°S to -44°S and longitude limits 110°E and 160°E. The scale is independent and latitudes and longitudes are expressed to the nearest 1/10th of a minute.

Map of zooplankton biomass in Australian waters. Data collected from oceanographic surveys conducted between 1959 and 1964 onboard the vessels "Gascoyne" and "Diamantina" using a Clarke-Bumpus Oblique Haul, with zooplankton biomass expressed in milligrams per cubic metre. These maps have been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project.

Swath-mapping of the seabed started soon after the Second World War, with small towed sidescan sonars providing images and built-in multi beam sonars providing bathymetry contour maps. Since then, variants of both systems have developed enormously to cover all water depths, and many of them can produce both acoustic imagery and contours. Today, swath widths of up to seven times the water depth allow rapid and accurate mapping. Swath-mapping has largely replaced the far less efficient single-beam profiling as a mapping tool. Several deepwater systems have been used on the Australian margin, and this paper concentrates on their use. At this stage, less than 5% of Australias offshore jurisdiction (larger than our onshore jurisdiction) has been mapped. HMAS Cook was brought into service in the 1960s with a very early SeaBeam multibeam system. Its most notable scientific successes were in 1989, when it was used in conjunction with the long-range towed GLORIA sidescan sonar system. Geologically important results were obtained off the Great Barrier Reef, south of Sydney, and west of Robe in South Australia. Since then, a number of transits through Australian waters, using modern SeaBeam systems, have been carried out by US institutions. In 1997, AGSO used R.V. Melville to map a large area off eastern Tasmania and in Bass Strait. Spectacular sidescan sonar images (with far higher resolution than those from GLORIA) and associated bathymetry have been obtained in the back-arc basins of Papua New Guinea by the SeaMarc II and HMR1 systems. The first major HMR1 survey in Australian waters was carried out in 1994 on the Macquarie Ridge with AGSO providing R.V. Rig Seismic as the platform. In 1994, AGSO used the French R.V. L Atalante with the Simrad EM12D multibeam system for mapping off Tasmania. The magnificent contour maps and images have revolutionised our geological understanding of an area three times that of Tasmania, and have enabled us to target seabed sampling programs for a greatly improved understanding of geological evolution and petroleum potential. These maps have been of substantial benefit to fishermen and biological and fisheries researchers, as have the Melville maps from eastern Tasmania. Several transit surveys using L Atalante have provided useful maps elsewhere off Australia. Government is considering how to develop our knowledge base to allow effective management of our vast offshore jurisdictional area: a 200 nautical mile Exclusive Economic Zone; and, beyond that, an extension of the legal Continental Shelf, which AGSO has been directed to map by 2004, to allow a maximum claim under the UN Law of the Sea provisions. A key element in management activities is adequate maps, which require methodical mapping of the seabed, using swath-mapping techniques. The RAN Hydrographic Service is acquiring vessels and systems capable of mapping the continental shelf. A national program, to map the entire Australian jurisdiction of 10 million km" beyond the continental shelf, but excluding the Australian Antarctic Territory, would take about 12 years and cost about $ 150 million, including all facets from acquisition to processing and storage, interpretation, and provision of digital data to the public. Such a program has strong multidisciplinary scientific, industrial and bureaucratic support, and would provide the information to properly manage our jurisdiction.

The National Catchment Database is a linked set of spatial layers and associated attribute tables describing key elements of the surface water hydrology of the Australian continent at a map scale of about 1:250,000. It is built upon the representation of surface drainage patterns provided by the GEODATA national 9 second Digital Elevation Model (DEM) Version 3 (ANU Fenner School of Environment and Society and Geoscience Australia, 2008). The stream network and catchment boundaries contained within the database form foundation elements of the Bureau of Meteorology's Australian Hydrological Geospatial Fabric (Geofabric), the spatial framework that underpins the Australian Water Resources Information System (AWRIS) (http://www.bom.gov.au/water/geofabric/index.shtml). This database adds additional environmental attributes not available through the AHGF. The database contains Levels 1 (drainage divisions) and 2 (aggregated river basins group) National Catchment Boundaries (NCB) in raster format including NCB Pfafstetter coding. The Vector format is available from the Bureau's Geobraic website.

The NISB Habitat Map was created by the University of Tasmania for a partnership between the Department of Climate Change and the National Land and Water Resources Audit. It supports the DCC/Audit partnership by providing a nationally consistent set of the available mapping data for those habitats that occur between the approximate position of the highest astronomical tide mark (HAT) and the location of the outer limit of the photic benthic zone (approximately at the 50-70 m depth contour). This area is broadly equivalent to the 'inner' and 'mid-shelf' regions identified by Geoscience Australia. The resulting map data set forms a core component of the ECM National Habitat Map Series. The habitat classes include: coral reef, rock dominated habitat, sediment dominated habitat, mangroves, saltmarsh, seagrass, macroalgae and filter feeders (e.g. sponges), as defined in the NISB Habitat Classification Scheme. The scheme is designed to support the development of marine 'ecoregions' or bioregional subregions. Details of the scheme and the process of its development are available in National Intertidal/Subtidal Benthic (NISB) Habitat Classification Scheme Version 1 (Mount, Bricher and Newton, 2007). The NISB Habitat Map consists of two layers for each state. _NISB.shp consists of the entire available habitat mapping at a resolution finer than 1:50 000 (with a few exceptions, outlined in the data quality section below). _NISB_PLUS.shp consists of all the data in _NISB.shp along with coarser resolution data, including NVIS and OzEstuaries data. These layers were used to produce the National ECM Key Habitat Distribution Map Series 10 km and 50 km tile maps.

Note: This data is labelled as “NISB_plus”, indicating that it is the NISB Habitat layer plus other lower quality layers.

This dataset maps the geomorphic habitat environments (facies) for 103 Western Australia coastal waterways. The classification system contains 11 easily identifiable and representative environments: Barrier/back-barrier, Central basin, Channel, Coral, Flood- and Ebb-tide Delta, Fluvial (bay-head) Delta, Intertidal Flats, Mangrove, Rocky Reef, Saltmarsh/Saltflat, Tidal Sand Banks (and Unassigned). These types represent habitats found across all coastal systems in Australia. Western Australia has a diverse range of Estuaries due to different climates. Ranging from mostly "near pristine" and tide influenced estuaries in the north to "near pristine" wave dominated estuaries in the southwest region.

The Revised Universal Soil Loss Equation (RUSLE) estimates the annual soil loss that is due to erosion using a factor-based approach with rainfall, soil erodibility, slope length, slope steepness and cover management and conservation practices as inputs. The collection is (i) a set of maps that represent the RUSLE factors, (ii) a map of the RUSLE estimates of soil erosion in Australia and (iii) a map of the uncertainty in the estimates of erosion.

This is Version 1 of the Australian Soil Available Water Capacity product of the Soil and Landscape Grid of Australia.

The Soil and Landscape Grid of Australia has produced a range of digital soil attribute products. Each product contains six digital soil attribute maps, and their upper and lower confidence limits, representing the soil attribute at six depths: 0-5cm, 5-15cm, 15-30cm, 30-60cm, 60-100cm and 100-200cm. These depths are consistent with the specifications of the GlobalSoilMap.net project (http://www.globalsoilmap.net/). The digital soil attribute maps are in raster format at a resolution of 3 arc sec (~90 x 90 m pixels).

These maps are generated by combining the best available Digital Soil Mapping (DSM) products available across Australia.

Attribute Definition: Available water capacity computed for each of the specified depth increments; Units: %; Period (temporal coverage; approximately): 1950-2013; Spatial resolution: 3 arc seconds (approx 90m); Total number of gridded maps for this attribute: 18; Number of pixels with coverage per layer: 2007M (49200 * 40800); Total size before compression: about 8GB; Total size after compression: about 4GB; Data license : Creative Commons Attribution 4.0 (CC BY); Variance explained (cross-validation): 0.4%; Target data standard: GlobalSoilMap specifications; Format: GeoTIFF. Lineage: The National Soil Attribute Maps are generated by combining the best available digital soil mapping to calculate a variance weighted mean for each pixel. For this soil attribute the Australia-wide three-dimensional Digital Soil Property Maps are the only maps available. Thus the modelling for this soil attribute only used Decision trees with piecewise linear models with kriging of residuals developed from soil site data across Australia. (Viscarra Rossel et al., 2015a).

The International Map of the World (IMW) series is no longer maintained, and printed copies of this map are no longer available. The Australian portion of the series consists of 49 maps. They were produced to an international specification using the R502 series at 1:250,000 scale as source material. Production commenced in 1926 and was completed in 1978. The maps were revised from time to time and the last reprint was undertaken in 2003. Each standard map sheet covers 4 degrees of latitude by 6 degrees of longitude and was produced using a Lambert Conformal Conic projection with 2 standard parallels. The series has recently been superseded by the 1:1 000 000 topographic map general reference.

The Hydro Water Bodies data set comprises the following hydrographic features: Reservoirs, Dams, Lakes (permanent, intermittent and mainly dry), Land Subject to Inundation and Flooding. It is one of a collection of individual hydrographic data sets that topologically structured and comprise point, line and polygon data types at a general capture scale of 1:50,000. It is used in a variety of applications, particularly in natural resource management, planning and development, and digital map publication. Through the Commonwealth (Bureau of Meteorology) funded Australian Hydrological Geospatial Fabric (Geofabric) project 2011-2012 respective versions of surface water datasets from the former DFW and former DENR were integrated to create a single authoritative database. Water bodies within Adelaide & Mount Lofty Ranges (Fleurieu Peninsula), Kangaroo Island and Northern & Yorke NRM regions were updated to a detailed survey specification. Subsequently, water bodies within the remaining area of A&MLR and the western part of the SA Murray-Darling Basin (Eastern Mount Lofty Ranges) regions were also updated to the detailed survey specification. Data in the pastoral regions of the State has been sourced from the Bureau of Meteorology (BoM) Geofabric Surface Cartography V2.1 AHGFWaterbody dataset (equivalent to Geoscience Australia's GEODATA TOPO 250K). The Geofabric data was integrated in June 2013.

The loess filter used to create CARS2000 resolves at each point a mean value and a sinusoid with 1 year period (and in some cases a 6 month period sinusoid - the "semi-annual cycle".) The provided "annual amplitude" is simply the magnitude of that annual sinusoid. CARS is a set of seasonal maps of temperature, salinity, dissolved oxygen, nitrate, phosphate and silicate, generated using Loess mapping from all available oceanographic data in the region. It covers the region 100-200E, 50-0S, on a 0.5 degree grid, and on 56 standard depth levels. Higher resolution versions are also available for the Australian continental shelf. The data was obtained from the World Ocean Atlas 98 and CSIRO Marine and NIWA archives. It was designed to improve on the Levitus WOA98 Atlas, in the Australian region. CARS2000 is derived from ocean cast data, which is always measured above the sea floor. However, for properties which do not change rapidly near the sea floor, this would not lead to a significant error. All the limitations of CARS2000 also apply here.

The ACT Water Areas dataset contains polygon information representing an area of land that is or may be covered in water, either intermittently or constantly, temporarily or permanently. The water features were digitised in 1995 from 1:10,000 Plan Series, 1:2,500 Cadastre, 1:2,500 Detail, 1:1,000 Detail and traced from Topobase.
