Albany-Fraser Block (Pemberton, Mt Barker, Bremer Bay), WA, 1977 (P446), 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 Albany-Fraser Block (Pemberton, Mt Barker, Bremer Bay), WA, 1977 survey were acquired in 1977 by the WA Government, and consisted of 32158 line-kilometres of data at 1500m line spacing and 150m 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.

Daly River Region AEM SkyTEM airborne electromagnetic survey

A SkyTEM airborne electromagnetic (AEM) survey was flown during the period 09 to 24 August 2017 in the Daly River Region, Northern Territory, Australia. The area is located in the 1:250000 map sheets, SD52-08 (Pine Creek), SD52-12 (Fergusson River), SD52-16 (Delamere), SD53-09 (Katherine) and SD53-13 (Larrimah) south-southeast of the city of Darwin. Approximately 3379 line kilometres of TEM and magnetic data were acquired. The projected grid coordinates have been supplied in GDA94 MGA Zone 52.
The aim of the survey is to provide geophysical information to support investigations of the regional groundwater system, identify regional groundwater sources and mitigate risk in irrigation development. It will provide data to allow for the modelling of the following at a reconnaissance scale:
a) trends in regolith thickness and variability
b) variations in bedrock conductivity
c) conductivity of key bedrock (lithology related) conductive units under cover
d) the groundwater resource potential of the region

New Zealand Community Fault Model – version 1.0

There has been a long-identified need in New Zealand for a community-developed three-dimensional model of active faults that is accessible and available to all. Over the past year, work has progressed on building and parameterising such a model – the New Zealand Community Fault Model (NZ CFM). The NZ CFM will serve as a unified and foundational resource for many societally important applications such as the National Seismic Hazard Model, Resilience to Natures Challenges Earthquake and Tsunami programme, physics-based fault systems modelling, earthquake ground-motion simulations, and tsunami hazard evaluation. 
Version 1.0 of the NZ CFM is nearing finalisation and release. NZ CFM v1.0 provides a simplified 3D representation of New Zealand’s crustal-scale active faults (including some selected potentially active faults) compiled at a nominal scale of 1:500,000 to 1:1,000,000. NZ CFM faults are defined based on surface traces, seismicity, seismic reflection profiles, wells, and geologic cross sections. The model presently incorporates more than 800 objects (i.e., faults), which include triangulated surface representations of those faults and associated parameters such as dip and dip direction, seismogenic rupture depth, sense of movement, slip direction, and net slip rate.

Characterising changes in isotope hydrochemistry through time in a high use, arid-zone aquifer

Alice Springs is an important centre for regional industry, tourism and transport in the Northern Territory. The town has approximately 29,000 inhabitants and 400,000+ visitors are wholly reliant on groundwater from aquifers in the Amadeus Basin. Current groundwater use in the Roe Creek Management Zone borefield is ~8,500 ML/yr, far in excess of the ~750 ML/yr of groundwater recharge to the area. As a result, groundwater levels in the Roe Creek borefield have fallen by ~1 m/yr since 1964. 
As part of the Exploring for the Future program, Geoscience Australia flew ~2375 line km of AEM, drilled 3 boreholes, took 34 SNMR readings and collected 21 groundwater samples for hydrogeochemical analysis in the Alice Springs project area. Hydrochemistry samples were analysed for major and minor chemistry, stable isotopes, carbon-14, chlorine-36, tritium, CFCs and SF6. In addition DENR NT have drilled a number of deep (500m) groundwater bores to analyse hydrogeochemistry and to monitor groundwater levels.
Over the last 40 years, there have been at least 4 generations of groundwater sampling for chemistry, stable isotopes and radioisotopes in the Amadeus Basin. The earliest samples were collected by Calf in 1978, followed by Jacobson in 1989, BRS in 1999-2000 and Geoscience Australia in 2017-18. 
During this period there have been at least 12 large rainfall events (&gt; 150mm), although only the anomalously wet year of 1974 showed significant groundwater recharge in the Amadeus Basin, the water table has fallen by over 40 metres and many additional bores have been drilled or deepened. In addition, many older bores were indifferently constructed while modern bores are targeted to specific aquifers and intervals. This paper looks at how these changes are reflected in groundwater hydrochemistry and isotopic values and what these changes may mean to the management of groundwater in Alice Springs.

AAO Pickanjinnie No 1, Queensland Of Associated Australian Oilfields NL

A,A.O. Pickanjinnie No. 1 was drilled by Associated Australian Oilfields N.L. on a seismic "high" near Pickanjinnie, approximately 20 miles east of Roma. Drilling was commenced on 27th May, 1960, and was completed on 12th July, 1960, at a total depth of 5213 feet. The drilling contractor was Mines Administration Pty Limited, and the rig used was a National T-32. A full programme of logging, testing and coring was undertaken.
The well was drilled in Mesozoic sediments to4490 feet; the Roma, Blythesdale, Walloon, Bundamba, Moolayember and Pickanjinnie Formations were penetrated in this section. The Permian Latemore Formationwas then encountered beneath a slight unconformity separating this formation from the overlying Mesozoic rocks. The Timbury Hills Formation, (1) Devonian, taken as local basement, was penetrated at 4835 feet and continued to total depth.
Eight formation tests were run, the results of which are summarized in Appendix 7. During the test of the interval 3976 - 4368 feet, over a period of 45 hours, gas flowed at a rate of 6,5 MMcf/D on one inch surface bean. The well was plugged from 4520 feet to total depth, filled with mud and capped, and completed as a gas producer on 29th July, 1960.
The results of the velocity survey of Pickanjinnie No. 1, made on 12th July, 1960, have modified the interpretation of an extensive seismic programme carried out in the region.

Horsham VIC Hydrogeological map of the Murray Basin series 1:250 000

The objectives of hydrogeologically mapping the Murray basin were to generate a set of maps at 1:250 000 scale to: 

show the influence of groundwater on land salinisation and surface water salinity 
delineate useable groundwater resources 
highlight present and potential salinity hazard and 
enhance community awareness and understanding of groundwater systems and processes 

and provide a groundwater data-base for the Murray Basin to facilitate land and water resource management decisions. 
The production of the Murray Basin Hydrogeological Map Series was a major coordinated Government action in the management of groundwater to combat degradation through salinisation and enable sustainable land and water use in the Murray Basin.  The Hydrogeological Map Series was a collaborative effort between the various water authorities of South Australia, Victoria and New South Wales. 
Explaining this product in detail is an article by Evans, W.R. 1992, "The Murray Basin Hydrogeological Map Series", Water pp. 20-23.

Regional Petroleum Prospectivity of the Cooper Basin - 2016 Digging Deeper Conference Presentation

The Cooper Basin is Australia's premier onshore hydrocarbon producing province and hosts a range of conventional and unconventional gas play types. This study investigates the petroleum generation potential of the basin's major Permian source rocks, to improve regional understanding of the basin's hydrocarbon prospectivity.
Source rock distribution, thickness, present-day amount of total organic carbon (TOC), quality (Hydrogen Index) and maturity were mapped across the basin, together with original source quality maps prior to the on-set of generation. Results of the source rock property mapping and basin-specific kinetics were integrated with 1D burial and thermal history models and a 3D basin model to create a regional pseudo-3D petroleum system model for the basin. The modelling outputs quantify the spatial distribution of both the maximum possible hydrocarbon yield, as well as the oil/ gas expelled and retained, for ten Permian source rocks. Monte Carlo simulations were used to quantify the uncertainty associated with hydrocarbon yields and to highlight the sensitivity of results to each input parameter.
The principal source rocks are the Permian coal and coaly shales of the Gidgealpa Group, with highest potential yields from the Patchawarra Formation coals and coaly shales. The broad extent of the Cooper Basin's Permian source kitchen and its large total generation potential (P50 scenario &gt;2000 bboe) highlights the basinÂ¿s significance as a world-class hydrocarbon province. The difference between the P90 (~800 bboe) and P10 (&gt;4000 bboe) scenarios demonstrate the range of uncertainties inherent in this modelling.

Darwin Harbour Habitat Mapping Program: Predicted standard error for interpolated surface of predicted surface of Total CO2 Flux in sediments

This resource contains a predicted total CO2 flux standard error grid 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 predicted total CO2 flux standard error grid 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 previous surveys GA4425 and GA0333 collected by GA, AIMS, NTG-DENR and Darwin Port Authority.
