Southern Cross Gravity Survey, 2010 (P200962), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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.
 This Southern Cross Gravity Survey, 2010 (P200962) contains a total of 6355 point data values acquired at a spacing of 2500 metres. The data is located in WA and were acquired in 2010, under project No. 200962 for Department of Industry and Resources (Western Australia).

Belemnite successions and faunal provinces in the southwest Pacific, and the belemnites of Gondwana

Dinoflagellate zonation allows a reasonably precise correlation of some Jurassic-Cretaceous coleoid-bearing sequences in Indonesia.  Papua New Guinea, and New Zealand. Macrofossils provide a precise New Zealand - New Caledonia correlation in the Middle Jurassic, and general correlation allows Australian belemnite-bearing sequences to be compared with those of other regions.  Comparisons of Indonesian and Papua New Guinean with New Zealand sequences show that the time-distribution of Belemnopsis is partly disjunct, Hibolithes and Conodicoelites is mostly disjunct, and Dicoelites is completely disjunct. Xiphoteuthids and Belemnitina are known only from New Zealand and New Caledonia; Duvalia and Chalalabelus only from Indonesia; and the Dimitobelidae only from New Zealand, Australia, and Papua New Guinea. New Zealand Middle and Late Jurassic Belemnopsis are morphologically distinct from those of Indonesia and Papua New Guinea. New Zealand Hibolithes are a morphologically coherent group different from the more diverse Indonesian and Papua New Guinean members of the genus, and Dicoelites and Conodicoelites of the two regions also differ. The much discussed and widely recognised uhligi-complex is incorrect in concept and has little correlative value.  A Jurassic and Early Cretaceous Tethyan Province populated by morphologically similar Hibolithes, and by Duvalia, Dicoelites, and Conodicoelites extended eastward from the Mediterranean region along the coast of Gondwana to at least Papua New Guinea.  Within that province Late Jurassic Ethiopian and Indo-Tethyan Subprovinces can be recognised, each based on a distinctive Belemnopsis lineage. A South Pacific Province based on Belemnitina and Belemnopseina extended from southern South America to New Zealand in the Middle and Late Jurassic, and possibly to Papua New Guinea in the Early Cretaceous.  The belemnite assemblages of other former Gondwana continents support this division. Although the Tethyan and South Pacific Provinces remained distinct from Middle Jurassic probably to the Early Cretaceous, some trans-Gondwana migration from Kimmeridgian time, mainly from Tethys to the South Pacific, occurred along the developing seaway between Africa-South America and India-Antarctica.

MRTAS NW Tasmania ppm thorium 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.
This radiometric thorium grid has a cell size of 0.00042 degrees (approximately 41m) and shows thorium element concentration of the North West Tasmania, Tas, 2001 (WTRMP Area B) in units of parts per million (or ppm). The data used to produce this grid was acquired in 2001 by the TAS Government, and consisted of 33834 line-kilometres of data at 200m line spacing and 80m terrain clearance.

Tropical Cyclone Impact Modelling System

This dynamic dataset is composed of data layers representing the potential damage arising from the impacts of Tropical Cyclone (TC) related winds on residential houses. The impacts are determined using information on the forecast track of the TC issued by the Bureau of Meteorology, nationally consistent exposure (residential building) and vulnerability (likely level of damage) information maintained by Geoscience Australia.
The tracks are based on the content of Technical Bulletins issued by the Bureau of Meteorology’s Tropical Cyclone Warning Centres every 6 hours for active TCs in the Australian region. As such, information is generated intermittently, depending on the occurrence of TCs. The tracks are a forecast only, so do not include past position information of the TC. Forecasts may extend up to 120 hours (5 days) ahead of the forecast time.
A wind field around each track is simulated using Geoscience Australia’s Tropical Cyclone Risk Model (TCRM, https://pid.geoscience.gov.au/dataset/ga/77484). This provides an estimate of the maximum gust wind speed over open, flat terrain (e.g. airports).
Local effects such as topography and land cover changes are incorporated via site wind multipliers (https://pid.geoscience.gov.au/dataset/ga/75299), resulting in a 0.2-second, 10-m above ground level wind speed, with a spatial resolution of approximately 30 metres.
The impacts are calculated using Geoscience Australia’s HazImp code (https://pid.geoscience.gov.au/dataset/ga/110501), which utilises the National Exposure Information System building data and a suite of wind vulnerability curves to determine the level of damage sustained by individual buildings (a damage index). The damage index values are aggregated to Australian Bureau of Statistics Statistical Area Level 1 regions, and can be assigned a qualitative damage description based on the mean damage index.

Mary River south, NT, 2000 (P1013), magnetic line data, AWAGS levelled

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.
 These line dataset from the Mary River, NT, 2000 survey were acquired in 2000 by the NT Government, and consisted of 30711 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Layered Geology Of Australia WMS

The Layered Geology of Australia web map service is a seamless national coverage of Australia’s surface and subsurface geology. Geology concealed under younger cover units are mapped by effectively removing the overlying stratigraphy (Liu et al., 2015). This dataset is a layered product and comprises five chronostratigraphic time slices: Cenozoic, Mesozoic, Paleozoic, Neoproterozoic, and Pre-Neoproterozoic. As an example, the Mesozoic time slice (or layer) shows Mesozoic age geology that would be present if all Cenozoic units were removed. The Pre-Neoproterozoic time slice shows what would be visible if all Neoproterozoic, Paleozoic, Mesozoic, and Cenozoic units were removed. The Cenozoic time slice layer for the national dataset was extracted from Raymond et al., 2012. Surface Geology of Australia, 1:1 000 000 scale, 2012 edition. Geoscience Australia, Canberra.

Geoscience Australia's GNSS Antenna Calibration Facility: Initial Results

Abstract for IGNSS 2015 conference:
A Global Navigation Satellite System (GNSS) antenna calibration facility has been established at Geoscience Australia, for determining individual antenna calibrations as well as aiding the establishment of typemean calibrations as used by the International GNSS Service (IGS). Studies have highlighted the importance of accounting for the variation in individual antenna calibrations for high precision positioning applications. In order to use individual antenna calibrations reliably, the repeatability of the calibration needs to be well understood. In this paper, we give an overview of the repeatability of calibrations for different antenna types. We also present a case study on the application of an individual GNSS antenna calibration in Australia and its effect upon positioning.

Digital Earth Australia Analysis Ready and Derivative Data Collection

Analysis Ready Data (ARD) takes medium resolution satellite imagery captured over the Australian continent and corrects for inconsistencies across land and coastal fringes. The result is accurate and standardised surface reflectance data, which is instrumental in identifying and quantifying environmental change. This product is a single, cohesive ARD package, which allows you to analyse surface reflectance data as is, without the need to apply additional corrections. 
ARD consists of sub products, including : 
1) NBAR Surface Reflectance which produces standardised optical surface reflectance data using robust physical models which correct for variations and inconsistencies in image radiance values. Corrections are performed using Nadir corrected Bi-directional reflectance distribution function Adjusted Reflectance (NBAR). 
2) NBART Surface Reflectance which performs the same function as NBAR Surface Reflectance, but also applies terrain illumination correction. 
3) OA Observation Attributes product which provides accurate and reliable contextual information about the data. This 'data provenance' provides a chain of information which allows the data to be replicated or utilised by derivative applications. It takes a number of different forms, including satellite, solar and surface geometry and classification attribution labels. 
ARD enables generation of Derivative Data and information products that represent biophysical parameters, either summarised as statistics, or as observations, which underpin an understanding of environmental dynamics. The development of derivative products to monitor land, inland waterways and coastal features, such as: 
- urban growth 
- coastal habitats 
- mining activities
- agricultural activity (e.g. pastoral, irrigated cropping, rain-fed cropping) 
- water extent 
Derivative products include: 
- Water Observations from Space (WOfS) 
- National Intertidal Digital Elevation Model (NIDEM) 
- Fractional Cover (FC) 
- Geomedian 
ARD and Derivative products are reproduced through a period collection upgrade process for each sensor platform. This process applied improvements to the algorithms and techniques and benefits from improvements applied to the baseline data that feeds into the ARD production processes. 
Value: These data are used to understand distributions of and changes in surface character, environmental systems, land use. 
Scope: Australian mainland and some part of adjacent nations.
