Rugosity Grid of Darwin Harbour

The Rugosity grid calculates the "true" surface area in relation to the planar surface area. It represents the rugosity of an area of seabed (Jenness, 2004). Higher values indicate more rugose seafloor. The grid was created from the bathymetry grid of Darwin Harbour. Please see the metadata of the bathymetry grid for more details (GeoCat No: 74915).

Wanna Mason Detailed Gravity (P198233), 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 Wanna Mason Detailed Gravity (P198233) contains a total of 310 point data values acquired at a spacing between 1000 and 6000 metres. The data is located in WA and were acquired in 1982, under project No. 198233 for CRA Exploration Pty Ltd.

GSNSW Marulan Mossvale total count 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 Marulan Mossvale total count grid geodetic has a cell size of 0.00061 degrees (approximately 62m) and shows the terrestrial dose rate of the Marulan-Mossvale, NSW, 1998.

Billabong Creek tmi rtp 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 magnetic grid has a cell size of 0.00021 degrees (approximately 21m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2001 by the NSW Government, and consisted of 32065 line-kilometres of data at 100m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.

pmd*CRC 40Ar/39Ar Geochronology and Halogen/Noble Gas Geochemistry of Mineralising Systems H4 Project. Final Project Report

The principal objective of the H4 Project was to evaluate existing techniques and develop new enabling technologies in geochronology and isotope geoscience to significantly improve our ability to constrain the timing of ore formation and, therefore, expand predictive capabilities. 
A fundamental goal was the evaluation of existing dating methods and interpretations, particularly with respect to gold deposits in low grade terrains, and to investigate potential new dating methods such as 40Ar/39Ar laser probe analyses of mica-bearing pyrite linked to gold mineralisation. A second major goal of the H4 project was to initiate development of halogen/noble gas geochemistry technology and expertise within the pmd CRC to enable this unique geochemical method to be applied to ore deposits in the flagship terrains in the second stage programme of pmd CRC.

AUSGeoid98 v.1.0 data files:  (sj53-15)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Eastern Otway Basin - Horizon Maps for the Onshore Areas at 1:250 000 scale

During the period 1991-94 the Australian Geological Survey Organisation (AGSO) participated ina co-operative study of the early development of the Otway Basin as part of a National Geoscience Mapping Accord project. The other partners in the project were the Geological Survey of Victoria(GSV), the Department of Mines and Energy, South Australia (MESA), and the Victorian Institute of Earth and Planetary Sciences (V1EPS) at Monash and La Trobe Universities. As part of the project, four subsurface horizons were mapped at 1:250000 scale across the onshore parts of thebasin using exploration industry and AGSO seismic data. This is the first time such mapping has been undertaken on a basin-wide scale in the Otway Basin. MESA undertook mapping in the SouthAustralian sector of the basin, GSV in the central (western Victorian) part of the basin, and AGSO and V1EPS in the eastern part of the basin.
This Record accompanies a folio of nine 1:250000 scale maps compiled by AGSO and V1EPS from the onshore eastern part of the basin centred on the Port Campbell Embayment, Colac Trough  andOtway Ranges. Four of these maps are presented as two-way times (milliseconds) to four mega-sequence boundaries together with interpreted structural information. The four mega-sequenceboundaries are, 1) - base Wangerrip Group, 2) - top Eumeralla Formation, 3) - top Crayfish Group, and 4) - top Palaeozoic basement. Also included in this Record are four associated isoehron and seismic line information maps at 1:250 000 scale and geophysical maps (gravity and magnetic data)at 1:250 000 and 1:1000 000 scales. The maps are designed to improve the general uderstanding of subsurface basin geometry as a guide to possible hydrocarbon resources both onshore andoffshore.

Darwin Harbour Habitat Mapping Program: Backscatter variance

This resource contains a GLCM (Grey-Level Co-occurrence Matices) variance grid of the backscatter data for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The GLCM (Grey-Level Co-occurrence Matices) variance grid of the backscatter data was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from a previous survey GA0333 collected by GA, AIMS and NTG-DENR. This statistic is a measure of local heterogeneity or dispersion around the mean. The variance increases when the neighbouring values differ from their mean.
