Abstract High quality coastal aquifer systems provide vast quantities of potable groundwater for millions people worldwide. Managing this setting has economic and environmental consequences. Specific knowledge the dynamic relationship between fresh terrestrial discharging to ocean seawater intrusion is necessary. We present multi- disciplinary research that assesses relationships throughflow intrusion. This combines numerical simulation, geophysics, analysis more than 30 years data from a...
Two different modes of cell division are adopted by progenitor cells to generate the neurons and glia cerebral cortex: they either divide symmetrically other progenitors or a pair postmitotic asymmetrically both cell. In this study we used lineage marker, BAG retrovirus, in embryonic day 16 rats combination with bromodeoxyuridine (BrdU) identify patterns generation cortex, investigated relationship between phenotype history their lineages. The location, birth order clonally related were...
Abstract Population growth and changing climate continue to impact on the availability of natural resources. Urbanization vulnerable coastal margins can place serious demands shallow groundwater. Here, groundwater management requires definition hydrogeology, particularly seawater interface. Electrical resistivity imaging (ERI) appears be ideally suited for this purpose. We investigate challenges drivers successful electrical with field synthetic experiments. Two decades intrusion monitoring...
Conversions of compressional seismic waves to electric fields have been measured in two boreholes drilled an unconfined sandy aquifer on the Gnangara Mound near Perth, Australia. The seismoelectric conversions at both field sites occurred vicinity water table 13‐m depth and yielded maximum amplitudes 1 μ V/m using a sledgehammer source surface. Partially cemented layers, inferred from geological geophysical logs, straddle may play role generating conversion influencing its amplitude...
Natural source electromagnetic methods have the potential to recover rock property distributions from surface great depths. Unfortunately, results in complex 3D geo-electrical settings can be disappointing, especially where significant near-surface conductivity variations exist. In such settings, unconstrained inversion of magnetotelluric data is inexorably non-unique. We believe that: (1) correctly introduced information seismic reflection substantially improve MT inversion, (2) a...
The integration of different geophysical data has the potential to provide more accurate estimate subsurface rock properties. Several methodologies and attempts have been developed over years with objective reducing exploration risk. We a cooperative joint-inversion approach intended facilitate recovery acoustic impedance (AI) using seismic magnetotelluric (MT) data. In this approach, MT provided pathway for iteratively building large-scale low-frequency information content not directly...
Abstract Changes in subsurface temperature distribution resulting from the injection of fluids into aquifers may impact physiochemical and microbial processes as well basin resource management strategies. We have completed a 2 year field trial hydrogeologically geochemically heterogeneous aquifer below Perth, Western Australia which highly treated wastewater was injected for large‐scale groundwater replenishment. During trial, chloride data were collected conventional monitoring wells by...
CO2CRC has made a significant investment into establishing the feasibility of conducting CO2 injection experiment shallow fault at Otway International Test Centre. Two appraisal wells drilled and cored through Brumbys Fault indicate extends to base upper 2 m thick Hesse Clay layer, which forms seal underlying Port Campbell Limestone aquifer. The does not have defined core; rather, it is expressed by an approximately 6-10 wide cataclastic zone. Permeability within variable, ranging from tens...
Abstract The evolution of coastal wetlands is a complex process which difficult to forecast, made more complicated by the addition changing climatic conditions. Here, long term ecological and geomorphological data are coupled geotechnical measurements at wetland in North Inlet estuary, South Carolina. methodology presented discussed context understanding system climate. Specifically, root shear strength Spartina alterniflora across range elevations was investigated using cone penetrometer...
Abstract The shallow aquifer on the Gnangara Mound, north of Perth, Western Australia, is recharged by winter rainfall. Water infiltrates through a sandy Podosol where cemented accumulation (B‐) horizons are common. They water retentive and may impede recharge. To observe wetting fronts influence soil unsaturated flow, we deployed time‐lapse borehole radar techniques sensitive to moisture variations during an annual recharge cycle. Zero‐offset crosswell profiling (ZOP) vertical (VRP)...
We compared the efficacy of two different designs hair-tube for detecting medium-sized, terrestrial marsupials in a range forest types south-east New South Wales. The were large-diameter PVC pipe (large hair-tube) and tapered hair-funnel. In addition, relative abundance forage-diggings same was estimated simultaneously order to provide an independent assessment their distribution within study area. Only hair-tubes out 620 contained hair that could be attributed target fauna, both from...
Abstract The storage of fluids in the subsurface is critical for a broad spectrum applications including managed aquifer recharge, liquefied carbon dioxide and hydrogen, geothermal heat extraction exploitation hydrocarbon. It surprising then, that there has been relatively little measurement vertical distribution poroelastic geologic formations as compared with permeability. We present experiments which fluid was injected into an important regional depth‐dependent strain response measured...
Abstract Seismic and electromagnetic methods are fundamental to Solid Earth research subsurface exploration. Acquisition cost reduction is making dense 3D application of these accessible a broad range geo-scientists. However, the challenge extracting geological meaning remains. We develop concept “textural domaining” for seismic reflectivity data. Dip-steered texture attributes combined with unsupervised learning generate sets volume rendered images accompanied by reference diagram. These...
