Darwin Harbour Habitat Mapping Program: Probability of occurrence of macro algae habitat

This resource contains a probability of occurrence grid of macro algae 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 probability of occurrence grid of macro algae 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.

GSWA South Pilbara 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 GSWA South Pilbara Doserate Grid Geodetic has a cell size of 0.00083 degrees (approximately 89m) and shows the terrestrial dose rate of the South Pilbara, Hickman Crater, WA, 2011. The data used to produce this grid was acquired in 2012 by the WA Government, and consisted of 134742 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Joint GSQ-GA NGA geochronology project: Mount Isa region, 2007-2008

This Geological Survey of Queensland - Geoscience Australia (GSQ-GA) geochronology record presents a compilation of 11 new zircon U–Pb SHRIMP geochronological results from the Mount Isa region, Queensland (Table 1). This data was collected through the collaborative GSQ-GA geochronology project in August 2007 as part of the National Geoscience Accord (NGA) and in support of ongoing geoscientific investigations and regional eological mapping by the GSQ in the Mount Isa region. A separate report for each sample is presented, containing a brief geochronological interpretation as well as information on sample location and geological context. All analytical data for each sample can also be obtained from the GA geochronology database OZCHRON, located at: www.ga.gov.au/oracle/ozchron/index.jsp.
Three samples were analysed from the south-western Mount Isa region within the URANDANGI 1:250 000 map sheet, two samples from the Kalkadoon–Leichhardt Belt from DUCHESS and CLONCURRY and six samples were analysed from the eastern Mount Isa region and the Boomarra Horst (DUCHESS and CLONCURRY and DOBBYN). An additional five samples were submitted for SHRIMP analysis but they failed to yield sufficient zircons for further investigation. A summary of all processed and analysed samples from this study is presented in Table 1, sample locations are shown in Figure 1.

Burakin Mt Marshall Lake Hillman Goomalling magnetic 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 Burakin Mt Marshall Lake Hillman Goomalling magnetic grid geodetic has a cell size of 0.00042 degrees (approximately 43m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1997 by the WA Government, and consisted of 133707 line-kilometres of data at a line spacing between 200m and 400m, and 60m terrain clearance.

North Winton Gravity Survey, Queensland, 1959 By Magellan Petroleum Corporation

This report covers gravity survey work conducted by Century Geophysical Corporation for Magellan Petroleum Corporation during the period 1st July to 31st December 1959. The survey was made following an aeromagnetic survey.
The gravity survey was intended to corroborate the magnetic interpretation; to provide further information as regards depth to basement and fault systems; and to indicate structural "highs" which could then be more precisely delineated by seismic reflection methods.
Gravity values were observed and plotted over the area surrounding Winton, Queensland. Both the gravity survey and the aeromagnetic survey indicate a fault or fault zone across the area. In an appendix by the Bureau of Mineral Resources, it is stated that a seismic profile crossing this zone indicates that this zone is either a fault or a monoclinal fold.
Magellan Petroleum Corporation are planning to deepen the water bore at Corfield, and if this does not provide sufficient information regarding the deeper rocks, a further stratigraphic test will be drilled at Winton.

An Enhancement of Earthquake Vulnerability Models for Australian Residential Buildings Using Historical Building Damage

Geoscience Australia (GA) has developed the Earthquake Risk Model (EQRM) as an open source software for earthquake hazard and risk assessment. In the EQRM, the likelihood of physical damage states of the building and the direct economic loss from the damage to structural and non-structural building components are estimated using fragility and vulnerability models, respectively. The methodology implemented in the EQRM to compute the likelihood of physical damage states and the economic loss is similar to the HAZUS methodology, which is based on the capacity spectrum method applied to a generalized Single-Degree-Of-Freedom (SDOF) model of the building. One limitation of the current approach is identified, which is the underestimation of the damage probability for non-structural acceleration-sensitive components with a consequent underestimation of economic loss. This underestimation is found to be more problematic for larger ground shaking intensities. To overcome the limitation of the current methodology, nonlinear time history analysis of a SDOF model is performed which enables the building of a relationship between absolute response acceleration and peak ground acceleration. The relationship is then used in computing damage probability for non-structural acceleration-sensitive components instead of using the spectral acceleration of the performance point computed using the capacity spectrum method. The effect of the refined vulnerability models is highlighted and discussed in scenario impact assessment for a building portfolio in Newcastle, Australia.
