GSNSW Grafton Tenterfield Doserate Grid Geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSNSW Grafton Tenterfield Doserate Grid Geodetic has a cell size of 0.0005 degrees (approximately 52m) and shows the terrestrial dose rate of the Grafton - Tenterfield, NSW, 2011. The data used to produce this grid was acquired in 2011 by the NSW Government, and consisted of 100488 line-kilometres of data at 250m line spacing and 60m terrain clearance.

GSNSW Grafton Tenterfield TMI Grid Geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This GSNSW Grafton Tenterfield TMI Grid Geodetic has a cell size of 0.0005 degrees (approximately 52m). The units are in nanoTesla (or nT).

Responses of Southern Ocean Seafloor Habitats and Communities to Global and Local Drivers of Change

Our knowledge of life at the Antarctic sea-bed has increased in the past decades with increasing ship-based surveys and monitoring sites, new technologies and data sharing. However, seafloor habitats and their communities exhibit high spatial variability and heterogeneity that limits our ability to assess the state of the Southern Ocean benthos on larger scales. The seafloor communities that inhabit the Antarctic shelf are often diversity hotspots. These habitats are important in the generation of ‘blue carbon’ and habitat for commercial fish species, for this reason we focus on these habitats. Many Southern Ocean seafloor habitats and their communities seem to be especially vulnerable to certain drivers of change including increasing ocean temperatures, iceberg scour, sea-ice melt, ocean acidification, fishing pressures, pollution and non-indigenous species. Some of the most vulnerable areas include those experiencing rapid regional warming and increased iceberg-scouring e.g. the West Antarctic Peninsula; where human activities and environmental conditions increase the potential for the establishment of non-indigenous species e.g. sub-Antarctic islands and tourist destinations and areas with fishing activities e.g. around South Georgia, Heard and MacDonald Islands.  Vulnerable species include calcifying species susceptible to increasing ocean acidity as well as slow-growing habitat forming species that can be damaged by fishing gears e.g. sponges, bryozoan and coral species. Management regimes can protect seafloor habitats and key species from fishing activities but only if they consider specific traits, such as longevity, food availability, their physiological adaptation and rare or common occurrences. Ecosystem-based management practices and long-term protected areas may be the most effective in the preservation of vulnerable seafloor habitats. However, action is needed to reduce carbon emissions to limit the impact of increasing ocean temperatures and ocean acidification. We focus on outlining seafloor responses to drivers of change observed to date and projections for the future. We discuss the need for action to preserve seafloor habitats under climate change and fishing pressures.

Isa-Georgetown Block A,QLD, 2000, Prospectivity Plus Initiative (P826), elevation line data

The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Isa-Georgetown Block A,QLD, 2000, Prospectivity Plus Initiative survey were acquired in 2000 by the QLD Government, and consisted of 34868 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance.

Digital Earth Australia Hotspots WMS

The Digital Earth Australia Hotspots web service has been developed as part of the Digital Earth Australia Hotspots national bushfire monitoring system. The service delivers hotspot data derived from (a growing number of) satellite-born instruments that detect light in the thermal wavelengths. The colour of the spot represents the time the Hotspot was last observed by a passing satellite (e.g. 0-2 hours). The colour does not indicate severity. Typically, the satellite data are processed with a specific algorithm that highlights areas with an unusually high temperature. In principle, however, Hotspots may be sourced from non-satellite sources.

L002 Roma Seismic Reflection Survey, QLD, 1949_1950

Seismic reflection survey has been conducted to help identify the possible oil-bearing structures, which were revealed by two residual gravity anomalies in a geophysical survey made by the Bureau of Mineral Resources. Good reflections were obtained in some parts of the area, but the quality was not consistent. The seismic results appear to confirm a small closure near one of the gravity anomalies. No definite closure is shown near the other anomaly.

Mineral Occurrences: Forgotten discoveries providing new leads for mineral supply

Demand for critical minerals, vital for advanced technologies, is increasing. This study shows that Australia’s richly endowed geological provinces contain numerous undeveloped or abandoned mineral occurrences that could potentially lead to new economic resources. Three study areas were assessed for critical mineral occurrences through database interrogation and literature review, namely the Barkly-Isa-Georgetown (BIG), Darling-Curnamona-Delamerian (DCD) and Officer-Musgrave (OM) project areas. The study found approximately 20,000 mineral occurrences across the three areas, with just over half occurring in the DCD region. Critical minerals were recognised in ~10% of all occurrences in BIG, ~10% in DCD and 70% in OM. Gold and base metal occurrences comprise 48% (OM), 81% (DCD) and 82% (BIG) of all occurrences in the study areas, with these metals in the DCD and BIG historically and presently important. This large-scale analysis and literature review of Australia’s forgotten mineral discoveries identifies potential new sources of critical minerals and, with the addition of mineralisation style to the data, contributes to predictive exploration methodology that will further unlock the nation’s critical mineral potential. These data are available through the Exploring for the Future portal (https://portal.ga.gov.au/persona/eftf).

Sedimentological Analyses from Deepsea Cores taken off Southwest Victoria, and Western and Southern Tasmania

Since 1985 the Bureau of Mineral Resources (BMR) has been involved in three coring cruises off southwest Victoria and Tasmania. A great amount of laboratory work has been done on the cores, generally on samples taken at 20cm intervals, by technicians in BMR's Division of Marine Geosciences and Petroleum Geology, and the aim of this record is to document the results.
The analytical work has been designed to be complementary to other scientific studies on the cores: physical descriptions, smear slide descriptions, and palaeontological examinations. The aim of all the work has been to adequately describe the variations which have taken place with time in the cores, and to relate these back to regional and local changes in depositional environment. The final intention of the studies is to build up a model of sedimentation on the continental margin which, in conjunction with reflection seismic data, can be used to interpret depositional packages in much older sequences.
The first sampling cruise was carried out in early 1985, aboard the West German research vessel Sonne (S0-36C) in a co-operative venture between BGR (German Geological Survey) and BMR. This survey took 43 cores off west Tasmania and on the South Tasman Rise (Figures 1B and 2) These cores varied in length from 0.55m to 7.78m (Table 1),and full station data are given in Hinz et al. (1985). Bolton et al. (1988)described six cores from the South Tasman Rise containing ferro manganese crust and nodules. Grainsize and CaCO3 analyses for 9 Sonne cores are presented in this Record.
The second sampling cruise, BMR Cruise 67, was carried out by BMR's research vessel Rig Seismic in 1987, off southwest Victoria and western Tasmania (Figures lA and 3). This survey took 54 cores varying in length from 0.10m to 3.64m (Table 2), and full station data are given in Exon, Lee et al. (1987) and Exon, Lee et al. (1989). Grainsize and CaCO3 analyses on 35 cores carried out at BMR are reported here, as well as TOC (Total Organic Carbon %) and CaCO3 analyses from low in 15 cores carried out by AMDEL.
The third sampling cruise, BMR Cruise 78, was carried out by Rig Seismic in 1988, off western Tasmania (Figures 4 and 5). Altogether 38 core stations were occupied, of which 22 were successful. Core recovery varied from 0.02m to 7.33m (Table 3) and full station data will be given in Exon, Lee and Hill (1989). Grainsize and CaCO3 analyses from 10 cores are reported here.

Singleton 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD.
