Seawater intrusion and aquifer compartmentalisation in the Darwin rural area

Groundwater is the primary source of water for residential and agricultural use in the Darwin rural area, and also supplies one third of Darwin’s city water. In the Howard East area, groundwater bores are screened in the Koolpinyah Dolomite aquifer, a ‘spill and fill’ aquifer that responds to wet-dry seasonal cycles. The 2018-2019 wet season saw low levels of rainfall and groundwater recharge, resulting in significant water stress. The Koolpinyah Dolomite aquifer is geologically complex, and is intersected by faults and/or shear zones that may compartmentalise the aquifer or act as preferential flow paths for groundwater. This project was initiated to better understand the influence of these geological features on potential seawater intrusion.
The geology and hydrogeology of the Howard East area has been refined using airborne electromagnetic (AEM) and airborne magnetic data collected for this project as part of the Geoscience Australia’s Exploring for the Future Programme. This AEM dataset was compared with previous AEM and borehole data to investigate changes in groundwater quality and dynamics. Water level loggers were installed in existing monitoring bores close to production bores for town water supply and the fault/shear zones. Pumping data were supplied by the bore-field operator, and data were interrogated to capture background groundwater dynamics and drawdown responses to pumping. Drawdown responses from either side of different geological structures were compared to test if aquifer compartmentalisation is occurring. Groundwater samples were collected throughout the area to investigate groundwater age and quality, and to test if possible aquifer compartmentalisation is affecting groundwater composition.
Preliminary analysis suggests that geological faults/shear zones compartmentalise the aquifer. Work is ongoing to assess the role of structures in seawater intrusion. The findings from this project will be used to inform bore-field and seawater intrusion management.

GSWA Perth Basin North Uranium 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 uranium grid has a cell size of 0.00083 degrees (approximately 87m) and shows uranium element concentration of the Perth Basin North, WA, 2011 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2011 by the WA Government, and consisted of 93199 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Wilkatana Boresite Gravity (P195040), 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 Wilkatana Boresite Gravity (P195040) contains a total of 130 point data values acquired at a spacing of 850 metres. The data is located in SA and were acquired in 1950, under project No. 195040 for Santos Ltd.

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.

Duketon, WA, 1994 (P613), 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 Duketon, WA, 1994 survey were acquired in 1994 by the WA Government, and consisted of 47160 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.

Introduction to Chaos Engineering

Tammy Butow visited Geoscience Australia to give us an introduction to chaos engineering! Tammy is Principal Site Reliability Engineer at Gremlin, former Senior SRE Manager at Dropbox, and co-founder of GirlGeekAcademy.
For those who aren't familiar with chaos engineering, it's a new approach to testing that involves intentionally injecting failures into live systems. Netflix were the pioneers in this space; you might have heard of their Chaos Monkey system.
This was an exciting opportunity to hear the real-world experiences of a chaos engineering expert.
This talk is presented as part of the Distinguished Geoscience Australia Lecturer series on 5 February 2018

Atlas of isoseismal maps of Australian earthquakes, part 2

This atlas of isoseismal maps of Australian earthquakes documents the ground intensity effects of 79 earthquakes. Most of these earthquakes originated in Queensland, northern New South Wales, and South Australia before 1982, and were not documented in the first atlas {BMR Bulletin 214) because their maps were not available at the time of publication; the remainder occurred in 1982 and 1983. The earliest map is for the November 1875 Mackay (Qld) earthquake and the most recent for the 1983 Beltana (SA) earthquake. This Bulletin and Bulletin 214 incorporate 163 maps from 149 earthquakes felt on the Australian continent, and provide a comprehensive database for earthquake risk assessments. Although the largest Australian earthquakes were included in Bulletin 214, this atlas contains maps of several early earthquakes of significance. These include the 1883 Gayndah (Qld), the 1886 Yass (NSW), and the 1913 Ravenswood (Qld) earthquakes, which had Richter magnitudes of 5.9, 5.5, and 5.7 respectively. The atlas is arranged in the same format as Bulletin 214: the isoseismal maps are presented in chronological order, each facing a page containing a brief description of the earthquake and the methods used to obtain the intensity data.
