A GNSS Survey of the Ramu-Markham Fault, Papua New Guinea

The Ramu-Markham Fault (RMF) runs along the northern edge of the Markham Valley in eastern Papua New Guinea’s Morobe Province. It is the active plate boundary between the South Bismarck Plate and&nbsp;the New Guinea Highlands/Papuan Peninsula Blocks, and is thought to accommodate about 4 cm/yr of convergence associated with the Finisterre arc-continent collision. Because Papua New Guinea’s recently published national seismic hazard map revealed a potential vulnerability of its 2nd largest city, Lae, to RMF earthquakes, Lae has become the focus of a seismic risk study. One of the aims of this study is to improve the characterisation of the earthquake potential along the RMF, and for this reason a new Global Navigation Satellite System (GNSS) campaign has been undertaken to re-survey over 70 existing benchmarks in and around Morobe Province, including about 35 benchmarks in and around the city of Lae itself. The vast majority of these benchmarks have now been surveyed, and in this paper we discuss the survey and a preliminary analysis of the data.

Tasmania (P198591), 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 Tasmania (P198591) contains a total of 2 point data values acquired at a spacing of None metres. The data is located in TAS and were acquired in 1985, under project No. 198591 for Bureau of Mineral Resources (BMR).

A novel framework for combining polarimetric Sentinel-1 InSAR time series in subsidence monitoring - A case study of Sydney

The city of Sydney, Australia has been growing rapidly over the last decades, with rapid development of residential and transportation infrastructure. Land subsidence associated with the urban development can lead to serious issues which should be thoroughly understood and carefully managed. Hence&nbsp;this study developed an enhanced multi-polarisation time-series InSAR (Pol-TS-InSAR) processing framework to address this challenging application.&nbsp;This is done by integrating the information from different polarimetric channels with different weighting during the TS-InSAR analysis. Ninety&nbsp;dual polarization Sentinel-1 images&nbsp;acquired from&nbsp;2019 to 2022 are analysed using the developed&nbsp;Pol-TS-InSAR to map the land subsidence in Sydney with the assistance of the GPS measurements. Improvement of measurement points density from Pol-TS-InSAR is observed compared to the single polarimetric TS-InSAR counterpart for all land use types (ranging between 21% and 99%). The comparison between the Pol-TS-InSAR measurements and GPS measurements shows an&nbsp;absolute mean difference and RMS difference of 0.7 mm/yr and 0.9 mm/yr, respectively, in line-of-sight (LoS) direction. The ground subsidence results obtained have been investigated.&nbsp;It is found that the main subsidence factors in Sydney are related to groundwater extraction, mining activities, underground tunnel construction and landfill, which the latter two factors are less aware previously. In additional to these factors, land subsidence related to high-rise building construction has also been observed, even though the impact seems to be less significant than other factors.

Determining aquifer hydraulic parameters using Surface Nuclear Magnetic Resonance (SNMR) data: the Paleozoic Bonaparte Basin, East Kimberley, Australia

Nuclear magnetic resonance (NMR) is an analytical technique used in geophysical investigations where a magnetic field is induced to produce an NMR response from protons in water molecules in the subsurface. Surface nuclear magnetic resonance (SNMR) data are inverted to produce a layered earth model of water content in the uppermost~100 m of the earth’s crust. Given the quick and non-invasive nature of data-acquisition and the fact that water content data can be simply transformed to hydraulic conductivity data, SNMR is a promising technique for mapping the distribution and properties of aquifers in the near surface.
Groundwater resources in the Paleozoic Bonaparte basin were mapped using a multidisciplinary, multi-physics approach. This study revealed a multi-layered hydrostratigraphy comprising of a stacked sequence of aquifers and aquitards and significant fresh groundwater resources within the basin. As part of these investigations &gt;100 SNMR soundings were collected, inverted, and integrated with other datasets to estimate hydraulic conductivities and transmissivities for the main aquifers in the basin.
Hydraulic conductivities were estimated by inserting SNMR inversion parameters T2* (decay of magnetisation) and ϕ (effective porosity) into the Schlumberger-Doll Research (SDR) equation. The ‘optimal’ formation dependent constant (C) was estimated by minimising the misfit between SNMR estimates of hydraulic conductivity and hydraulic conductivity estimates from co-located slug and pump tests.
The results revealed that the median hydraulic conductivity for the three main aquifers (Keep Inlet, Kuriyippi, and Tanmurra Formations) all fall within a range of three orders of magnitude (10-1 to 102 m/day). Of these the Kuriyippi had higher transmissivities (~5 m/day) than the Keep Inlet formation (~0.8 m/day). The deeper Tanmurra formation had the highest hydraulic conductivity distribution (~30 m/day, 50th percentile), however, data were only collected at ten locations for this aquifer and, therefore, these results are unlikely to be representative of the aquifer in general, particularly at depth.  This research demonstrates that SNMR is a useful technique for characterising the hydraulic properties of near-surface formations, particularly in areas where boreholes are sparse.

Rawlinson dose rate 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 Rawlinson dose rate grid geodetic has a cell size of 0.00083 degrees (approximately 88m) and shows the terrestrial dose rate of the Rawlinson, WA, 1998. The data used to produce this grid was acquired in 1998 by the WA Government, and consisted of 48394 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Alligator River, Mt.Evelyn, Cobourg Peninsula, NT, 1971/72 (P391), 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 Alligator River, Mt.Evelyn, Cobourg Peninsula, NT, 1971/72 survey were acquired in 1972 by the NT Government, and consisted of 12967 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.

Adavale Basin region: Other resource potential data guide

Publicly available geological data in the Adavale Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains an assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region.
Geochemical analysis of gas samples from petroleum boreholes in the basin shows various concentrations of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is still unknown. The Adavale Basin also has the potential for underground hydrogen storage in the Boree Salt. Given the depth of the Boree Salt (wells have intersected the salt at depths below 1800 m) and the high fluid pressure gradient in the basin, the construction of underground salt caverns should include consideration of stability and volume shrinkage. 
Mineral occurrences are all found in the basins overlying the Adavale region. However, they are small (thousands of tonnes range) and not currently of economic interest. The Adavale Basin has potential for base and precious metal deposits due to suitable formation conditions, but the depth of the basin makes exploration and mining difficult and expensive. There are no identified occurrences or resources of coal in the Adavale Basin. Given the depth of the basin, extraction of any identified coal would probably be uneconomic, with the potential exception of coal seam gas extraction.
An assessment of CO2 geological storage also shows prospective storage areas in the Eromanga Basin within the Adavale Basin region in the Namur-Murta and Adori-Westbourne play intervals.
