National Base Map - without labels WMTS

The National Base Map - without labels service provides seamless topographic colour mapping for the whole of Australia, including the outer islands of Norfolk, Lord Howe &amp; Macquarie Islands, the external territories of Cocos (Keeling), Christmas, Heard and McDonald Islands and the Australian Antarctic Territory. The service consists of data sourced from Geoscience Australia, Australian Antarctic Division &amp; OpenStreetMap. The data for Christmas Island has been sourced from the Christmas Island Edition 1 NATMAP Topographic Mapping dataset (1:30,000 scale). The data for Cocos (Keeling) Islands has been sourced from the Cocos (Keeling) Islands Edition 1 NATMAP Topographic Mapping dataset (1:25,000 scale). Vegetaion for the the Australian continent is an aggregated layer from ACLUMP (Australian Collaborative Land Use and Management Program). The topographic information was checked in 2008 using satellite imagery, and supplemented using other sources in 2009. Limited field checking has been undertaken for these data and therefore some information may not be accurate. Information and assistance was supplied by the Attorney General's Department (Territories of Australia) and Department of Environment, Water, Heritage and the Arts (Parks Australia). Geoscience Australia gratefully acknowledges contibutions to data content.) When viewing the map of mainland Australia beyond 1:100,000 scale, the data is derived from the Geoscience Australia GEODATA TOPO 250K product, except roads which are OpenStreetMap data, and in from 1:100,000 scale the data is derived from OpenStreetMap data ( © OpenStreetMap contributors). The suburbs layer is sourced from the Suburb 2018 and 2020 data, Australian Bureau of Statistics. The map portrays detailed graphic representations of features that appear on the Earth's surface. These features include cultural, hydrography, marine, transport, vegetation and relief themes. The SRTM data was acquired by NASA in February 2000 and was publicly released under Creative Commons licensing from November 2011 in ESRI Grid format. The SRTM DEM has quite different characteristics to DEMs derived by interpolation from topographic data. The SRTM data is derived from radar measurements that are dense (there is essentially a measurement at almost every grid cell) but noisy. The main processing of the SRTM DEM product has included: stripe removal, void filling and vegetation offset removal. Processing methods are further described in the 1 and 3 second SRTM Derived Products User Guide (Geoscience Australia, 2011). The bathymetry image used for this map is sourced from Natural Earth.

A Rapid Method to Characterize Seabed Habitats and Associated Macro-Organisms

This study presents a method for rapidly collecting, processing, and interrogating real-time abiotic and biotic seabed data to determine seabed habitat classifications. This is done from data collected over a large area of an acoustically derived seabed map, along multidirectional transects, using a towed small camera-sled. The seabed, within the newly designated Point Harris Marine Reserve on the northern coast of San Miguel Island, California, was acoustically imaged using sidescan sonar, then ground-truthed using a towed small camera-sled. Seabed characterizations were made from video observations, and were logged to a laptop computer (PC) in real time. To ground-truth the acoustic mosaic, and to characterize abiotic and biotic aspects of the seabed, a three-tiered characterization scheme was employed that described the substratum type, physical structure (i.e., bedform or vertical relief), and the occurrence of benthic macrofauna and flora. A crucial advantage of the method described here, is that preliminary seabed characterisations can be interrogated and mapped over the sidescan mosaic and other seabed information within hours of data collection. This ability to rapidly process seabed data is invaluable to scientists and managers, particularly in modifying concurrent or planning subsequent surveys.

Post-cruise Report AGSO Survey 217 : Joint Italian/Australian Marine Geoscience Expedition Aboard the R.V. Tangaroa to the George Vth Land Region of East Antarctica during February-March, 2000 : Australian National Antarctic Research Expeditions Project no. 1044, Wilkes Land Glacial History (WEGA)

The geophysical data collected includes a total of 1827 km of multi-channel seismic data and 562 km of Chirper sonar data. A total of 11 gravity cores, 28 piston cores, 18 surface grabs and 11 short trigger cores were collected on the voyage. Water profile (CTD) measurements and water samples were collected at nine stations and seabed bottom photographs were made at 11 stations. The expedition discovered and mapped a shelf sediment drift deposit covering about 400 km2 lying in an &gt;800m deep section of the George Vth basin west of the Mertz Glacier. It is a true "drift" deposit, since these sediments exhibit a depositional architecture indicative of contour-parallel sediment transport. A significant observation is that the drift thins to the north into an acoustically-transparent veneer; this observation implies that the drift is sourced from the outer continental shelf, with sediment being transported landwards, across the shelf and into an 850m deep inner shelf basin.

Reference lines, fault classification, transform systems and ocean-floor spreading: discussion

Wellman (1971) has presented erroneous data relating to lineaments in Papua New Guinea. The main faults and folds in Papua New Guinea as determined by ground and remote sensing surveys by the Bureau of Mineral Resources, the Geological Survey of Papua New Guinea and by oil exploration companies are shown on the new BMR - GSPNG 1:1,000,000 Scale geological map of Papua New Guinea.

Wellman (1971) in a recent issue of this journal produced an account of fault systems in the Pacific region. However, his Figure 5and related text (p.205) cannot go unchallenged in so far as they refer to the eastern part of the island of New Guinea, i.e., Papua New Guinea.

An example of the inaccuracy of Figure 5 (Wellman, 1971), is the omission of major faults such as the Owen Stanley Fault (Fig.1) and the Frieda Fault (Fig.2), and the depiction of a non-existent major fault system (which he called the New Guinea Fault).

Exhaustive examinations of airphotos, both vertical and oblique, at scales from 1:20,000 to 1:80,000, and of side-looking airborne radarimagery, by numerous officers of the Bureau of Mineral Resources and theGeological Survey of Papua New Guinea during the last 5 - 10 years have failed to detect the lineations shown by Wellman. Furthermore, these studies, and extensive field mapping by government and oil exploration company geologists over the last 25 years, have revealed the existence
of the fault and fold systems shown here in Figures 3a and 4.

Although a strike slip type of movement is suspected for some of these faults only vertical movements have been proved. Thus the sinistral movement claimed for the imagined "New Guinea Fault" should not be regarded as typical of the fault system of Papua New Guinea.

Keppel Bay: Physical Processes and Biogeochemical Engineering

In recent years there has been concern that catchment-derived nutrients and sediments discharged by rivers into the lagoon of the Great Barrier Reef are having a deleterious impact on near-shore reef ecosystems. On average, the Fitzroy River delivers the second largest quantity of these materials to the lagoon after the Burdekin River. The Fitzroy Agricultural Contaminants Project (AC), which is a Coastal CRC project, included amongst its aims the development of an understanding of the fate and impact of these agricultural contaminants (nutrients and sediments) within the Fitzroy Estuary-Keppel Bay system.

Browse Basin Cretaceous and Cenozoic surface grids

Geoscience Australia completed a regional assessment of the geological carbon dioxide (CO2) storage potential and petroleum prospectivity of the Browse Basin, offshore northwest Australia. This dual-purpose basin analysis study provided a new understanding of the basin’s Cretaceous succession based on new information regarding basin evolution, sequence stratigraphy, structural architecture and petroleum systems. The basin’s tectonostratigraphic framework was updated, and the integration of revised and recalibrated biostratigraphic data with well log and seismic interpretations has enabled an improved understanding of variations in depositional facies and the spatial distribution of reservoir, seal, and source rock sections. The outputs include models and maps of environments of deposition, play fairways, common risk element maps for regional-scale assessment of CO2 storage potential and petroleum systems model (Abbott et al., 2016; Edwards et al., 2015, 2016; Grosjean et al., 2015; Palu et al., 2017a and b; Rollet et al., 2016b, 2017a,b, 2018).


This data pack includes 12 Cretaceous and Cenozoic horizons, and the regional fault maps produced from this study. This interpretation is based on data from 60 wells (Table 1) and 26 regional 2D and 3D seismic reflection surveys (Table 2) (Rollet et al., 2016a). Surfaces were converted from TWT to depth and integrated in a 3D geological model as input into a petroleum systems model (Palu et al., 2017a, b). 

Data layers include:

12 regional depth surface grids and arcmap files generated for key Cretaceous and Cenozoic horizons (Figure 1; Table 3): K10.0_SB (late Tithonian), K20.0_SB (Valanginian), K30.0_SB (Late Hauterivian), K40.0_SB (Aptian), K50.0_SB (Late Cenomanian), K60.0_SB (Early Campanian), K65.0_SB (Maastrichtian), T10.0_SB (Base Cenozoic), T24.0_SB (Ypresian), T30.0_SB (Rupelian), T33.0_SB (Aquitanian) and water bottom based on bathymetry after Whiteway (2009),

2 fault population shapefiles (Figure 2): polygon envelop of shallow faults that formed during the Cenozoic collision between Australia and Asia, and horizon fault boundaries of deep regional faults that were formed through the Permian to Cretaceous.

RV Investigator Voyage IN2017_T01 ADCP Data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2017_T01, titled: "Natural iron fertilisation of oceans around Australia: linking terrestrial dust and bushfires to marine biogeochemistry." The voyage took place from Sydney (NSW) to Broome (WA) between September 24 and October 8, 2017.

Data was collected for the duration of the voyage, excluding the search site for the wreck of the Macumba. Data was collected using UHDAS and post-processed using CODAS. Only the OS75 was in operation for this voyage, due to a fault with the OS150 pending repair. Drop keels were both deployed at mid extension, approx. 8.5m below the waterline.

See the voyage computing and electronics report for more details regarding data acquisition.

This dataset was processed and then archived within the CSIRO Oceans and Atmosphere (O&amp;A) Information and Data Centre (IDC) in Hobart.

Structure and stratigraphy of the central Great Barrier Reef

The Cainozoic evolution of the central Great Barrier Reef Province has been deduced from shallow, intermediate, and deep focus seismic reflection profiling.  For much of its history the province has been dominated by terrigenous sedimentation , principally controlled by the relative height of sea level. The earliest depositional episode recognisable beneath the continental shelf was the infilling of the Queensland Trough rift basin with alluvial fan and trunk stream deposits in the Late Cretaceous to Paleocene. As the region subsided further, this was replaced by a Paleocene to Eocene marginal and shallow marine coastal and marine onlap phase.  Three periods of low sea level in the late Oligocene, late Miocene, and late Pliocene to Pleistocene resulted in alluvial sedimentation across the shelf, and fluvial and wave-dominated deltaic progradation at the shelf edge, which produced 10-40 km of shelf out-building. During the intervening periods of high sea level, sedimentation was restricted to coastal deltaic progradation on the inner shelf and onlap of the continental slope by submarine fans, and the upper slope was extensively eroded. The reef facies may have first appeared as a fringing reef in the Eocene, but was only established as an extensive, apparently shelf-dominating facies during high sea levels associated with Pleistocene aggradational phases. The reefs, which appear to be only 150-250 m thick, grew on and occur within siliciclastic fluviatile and deltaic sediments, and not on antecedent carbonate platforms. Reef growth occurred during short periods of high sea level, and during the intervening and longer periods of low sea level the reefs were eroded subaerially.  Continual re-colonisation of sites throughout their growth history has produced reefs that are composite features made up of a series of remnant reefs separated by unconformities. A shelf-edge barrier reef system, now generally submerged, occurs along much of the central Great Barrier Reef Province, except near Palm and Magnetic Passages. This has modified upper slope deposition during periods of low sea level by funnelling fluvio-deltaic sediments through gaps in the barrier reef, directly feeding upper slope canyons and depositing submarine fans on the middle and lower slopes. During periods of high sea level the barrier reef has shed fine-grained carbonates and organic material to the upper slope. It appears that the central Great Barrier Reef region is unlikely to have been a major reef carbonate province at any but the most recent stage of its evolution.

eReefs GBR1 river tracers v2.0

Passive river tracer results derived from version 2.0 of the 1km-resolution shelf-scale hydrodynamic model of the Great Barrier Reef (GBR1).

This model configuration and associated results dataset may be referred to as "GBR1_H2p0_Rivers" according to the eReefs simulation naming protocol.

The model ran in near-real-time mode, updating daily, until January 2024 when the 2023/24 monsoon season caused damage to sensors in the catchments, and we lost access to the critical river-flow forcing dataset.

Phytoplankton Distribution and Abundance Dataset from the IN2021_V01 TEMPO Voyage

This dataset describes the distribution and abundance of phytoplankton collected during the Marine National Facility (MNF) RV Investigator research voyage IN2021_V01, titled Quantifying krill abundance for krill monitoring and management off the Australian Antarctic Territory. The voyage took place between 29 January and 24 March 2021, sailing from Hobart to Hobart as part of the 2021 TEMPO (Trends in Euphausiids off Mawson, Predators, and Oceanography) survey. The primary objective of the voyage was to estimate Antarctic krill biomass to support updates to the precautionary catch limit within CCAMLR Division 58.4.2-East and to improve understanding of krill habitat and ecosystem dynamics. As phytoplankton are a primary food source for krill, their distribution and abundance were surveyed along six north–south transects spanning 55°E to 80°E, extending from approximately 62–63°S to the sea-ice edge. Several transects overlapped with survey lines sampled during the 2006 BROKE-West voyage, enabling comparisons of ecosystem conditions over time.
