Summary
Unlocking critical metals from Australian sediments and ores. This project aims to explore the recrystallization of nickel-bearing minerals in laterites to extract nickel from stable mineral phases under ambient conditions. Highly-weathered Australian soils contain economic quantities of nickel but technologies to extract this metal are inefficient, leaving this vital resource underdeveloped. This project will use stable isotope tracers and three-dimensional atomic-scale tomography to resolve th ....Unlocking critical metals from Australian sediments and ores. This project aims to explore the recrystallization of nickel-bearing minerals in laterites to extract nickel from stable mineral phases under ambient conditions. Highly-weathered Australian soils contain economic quantities of nickel but technologies to extract this metal are inefficient, leaving this vital resource underdeveloped. This project will use stable isotope tracers and three-dimensional atomic-scale tomography to resolve the recrystallization mechanisms, and determine their role in natural environments and their applicability to natural ores. Expected outcomes include strategies to process nickel-rich laterites, of high interest to industry and society in Australia and abroad.This project will exemplify the need to promote novel solutions to reduce the financial and environmental cost of processing natural resources.Read moreRead less

Summary
New frontier in Geoscience: A tandem trace element and isotopes facility. The project aims to integrate a multicollector mass spectrometer with the existing laser ablation laboratory at Southern Cross University to establish a unique facility offering tandem trace element and isotopes analysis. This will provide new methodological advancement by expanding the analytical range and obtaining information otherwise inaccessible to stand-alone instruments using traditional standardisation methods.

The project aims to integrate a multicollector mass spectrometer with the existing laser ablation laboratory at Southern Cross University to establish a unique facility offering tandem trace element and isotopes analysis. This will provide new methodological advancement by expanding the analytical range and obtaining information otherwise inaccessible to stand-alone instruments using traditional standardisation methods. Specifically, the integration of an innovative split stream system allows precise matching of elemental concentration with isotopic ratios, crucial for microscale resolution and data accuracy. The new infrastructure will confirm Australia’s leadership role and maintain its competitive advantage in geosciences.Read moreRead less

Summary
A facility for quantification and isotopic analysis of trace gases. This project aims to develop a new facility for the analysis of trace gases, including nitrous oxide, methane, hydrogen, carbon monoxide, and nitric oxide. This will provide two new capabilities for Australia: 1. It will further our ability to study how microbes cycle trace gases across the continuum from arid soils to the coastal ocean; 2. It will allow us to better understand microbial reactions that remove nitrogen pollution. ....A facility for quantification and isotopic analysis of trace gases.

It will allow us to better understand microbial reactions that remove nitrogen pollution. This will allow us to better understand, monitor and manage microbial processes within soils, sediments, and waters that undertake key ecosystem services, including removal of nitrogen and pollutant gases.

Unsaturated zone functioning in a semi-arid flash flood driven climate. Groundwater is the only perennial water source in arid and semiarid zones, which encompass 1/3 of the global landmass and 70 % of Australia. We still do not fully understand how the unsaturated zone contributes to groundwater recharge in semi-arid zone floodplains. We will study the dynamics of soil moisture, and its contribution to groundwater recharge respective to hydrological regimes and weather patterns. We will measure ....Unsaturated zone functioning in a semi-arid flash flood driven climate. Groundwater is the only perennial water source in arid and semiarid zones, which encompass 1/3 of the global landmass and 70 % of Australia. We still do not fully understand how the unsaturated zone contributes to groundwater recharge in semi-arid zone floodplains. We will study the dynamics of soil moisture, and its contribution to groundwater recharge respective to hydrological regimes and weather patterns. We will measure direct responses to flood events using loggers and compare them to indirect measurements inferred from hydrochemical and isotope tracer models to better understand recharge patterns, evaporative losses, and interactions between surface runoff, floodplains, and aquifers at different positions in the landscape.Read moreRead less

Ecohydrologic functioning of ephemeral streams. This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge.

This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge. The project will use environmental tracers, coupled with assessment of vegetation water use and numerical modelling, to assess resilience of ephemeral streams to changes in flows resulting from mining activities and climate-related shifts in recharge. Expected outcomes of the project include providing appropriate context for evaluating and adapting management to conserve scarce water resources. This project should significantly contribute to the sustainable management of both mineral and groundwater resources.Read moreRead less
