Multi-physics, Inter-disciplinary approaches for Groundwater System Investigations and Hydrogeological Assessments in Northern Australia

The development of Northern Australia has been identified as a national priority, with water availability being fundamental to economic development. Surface water options are limited hence identification of new groundwater resources and water banking options is essential.  Over the past 4 years, Geoscience Australia, in concert with State and Territory partners, has been involved in focussed groundwater investigations in 10 geographic areas as well as broader regional investigations (Figure 1). New data acquisition has included airborne electromagnetics (AEM); drilling (sonic, rotary mud, air core and diamond); slug and pump testing; ground geophysics (surface nuclear magnetic resonance, microgravity, passive seismic, seismic reflection and ground penetrating radar); borehole geophysics (induction, spectral gamma, nuclear magnetic resonance); hydrochemical and hydrodynamic analysis; age dating of water and landscape materials; and mapping (geomorphic, morphotectonic, regolith, geological and hydrological). These investigations inform hydrogeological assessments and water allocation and planning. 
Overall, this multi-physics, inter-disciplinary approach has been critical in enabling the rapid identification and assessment of significant new potential fresh groundwater resources within tectonically inverted Palaeozoic sedimentary basins in the Fitzroy Basin (WA), Bonaparte Basin (WA-NT), Wiso Basin (NT), and Southern Georgina Basin (NT), and helped define the extents of a new groundwater resource for the town of Alice Springs (NT). Potential brackish and saline groundwater resources have also been identified in Cenozoic paleovalleys and Tertiary and Paleozoic Basins.

GSQ Isa Georgetown Block B Qld ppm thorium 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 thorium grid has a cell size of 0.00048 degrees (approximately 52m) and shows thorium element concentration of the Isa-Georgetown Block B, QLD, 2000, Prospectivity Plus Initiative in units of parts per million (or ppm). The data used to produce this grid was acquired in 2000 by the QLD Government, and consisted of 42035 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance.

Tasmanian Tiers Airborne Magnetic, Radiometric and Digital Elevation Survey, TAS, 2021, (P5003), Block 1, magnetic line data

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.

Urban Seismic Risk in Java, Indonesia

Understanding and quantifying seismic risk in urban areas is critical to underpin policy designed to mitigate against future seismic losses and fatalities. This requires detailed knowledge of the earthquake hazard, the characterisation of assets in the built environment and its vulnerability to ground shaking.&nbsp;&nbsp;
In this research I have focused on the most populous island in the world, Java, Indonesia. With a population of 157 million it is home to over half of the country’s population, many of whom reside in some 27 million vulnerable masonry houses.&nbsp;Multidisciplinary data sources have been used to develop a nuanced and robust model of the built environment (exposure) at the island scale, identify the sources of uncertainty, and determine the sensitivity of seismic risk calculations to this uncertainty. This work has greatly advanced the understanding of seismic risk in Java and can be used to inform disaster risk reduction policy and management. The methods used in this study can be applied to other locations with low data availability in the Asia-Pacific.&nbsp;

NOAA satellite data in natural oil slick detection, Otway Basin, southern Australia

Crude petroleum in the form of thick oil or bitumen seeps in places from the sea floor off southeast South Australia, and periodically strands on the coasts of South Australia, western Victoria and western Tasmania. In this pilot study, National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer data acquired by the NOAA-9 satellite, during the period from 13 days before to I day after a reported stranding of 1000t on Kangaroo Island, was studied to try to detect the floating crude, map its drift path, and determine the location of the seepages. The studys failure to detect any oil slick on the ocean surface is attributed to the prevailing high percentage of cloud cover, and the calculated small area occupied by the slick in relation to the spatial resolution of the sensor, particularly after the oil had been degraded to bitumen. In the study area, continuing monitoring of locations and timing of strandings, and the associated meteorological conditions, are needed if the sites of oil seepage are to be determined. In such cloud-prone areas, monitoring of petroleum slicks by remote sensing could require sensors operating in the microwave part of the electromagnetic spectrum, but in areas with clearer skies the use of NOAA satellite data should be further investigated. If the locations of oil seeps can be thus identified, they may define locations of petroleum fields. Consequently, this type of investigation may be a relatively inexpensive exploration method in some offshore areas.

National Gravity and Magnetic Derivatives Customised for Data Analysis and Machine Learning

Purpose
This package comprises a set of 86 thematic grids (rasters) derived from national coverages of gravity and magnetic survey data. These datasets provide valuable information about the distribution of geological features, physical property variations, and the composition of the Earth's crust. All grids have been resampled to the same cell size, map extent, and projection to allow them to be integrated into predictive mapping and modelling workflows using machine learning. Users can download individual grids or the whole grid package. 
Input Data
The following Australian national datasets were used:
1. 2019 Australian National Gravity Grids: Free Air Anomaly, Complete Bouguer Anomaly, De-trended Global Isostatic Residual, 400 m cell size (Lane et al., 2020).
2. Total Magnetic Intensity (TMI) Grid of Australia 2019 - seventh edition Enhanced Products Package (Morse, 2020).
Processing
All processing of the national grids were undertaken using Intrepid software. The following was performed on the input data:
1. The grids were reprojected from GDA94 geodetic to Australian Albers (EPSG 3577).
2. The grids were aligned to the same grid cell registration point and interpolated to fit within an 80 m cell size using a cubic spline method to ensure that the cell locations for all images are common.
3. Various Fast Fourier Transforms (FFT) were applied to each grid 
    (see ‘Grids_for_Machine_Learning_dataset_notes.pdf’).
