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
Unravelling how aquatic coastal networks regulate nitrogen removal . The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches. Little is known about how the complex coastal landscape controls trade-offs that maximise nitrogen removal but minimise nitrous oxide (a potent greenhouse gas) emissions. The outcomes of this study will significantly advance our understanding of the coastal zone in regional and g ....Unravelling how aquatic coastal networks regulate nitrogen removal . The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches. Little is known about how the complex coastal landscape controls trade-offs that maximise nitrogen removal but minimise nitrous oxide (a potent greenhouse gas) emissions. The outcomes of this study will significantly advance our understanding of the coastal zone in regional and global nitrogen budgets. This will provide significant benefits such as a new science-based quantitative framework to facilitate best practice management to reduce terrestrial nitrogen loads and associated downstream impacts such as eutrophication, and reduce nitrous oxide emissions and associated global warming.

Laser ablation multiple split streaming. Laser ablation multiple split streaming: This geochemical facility with an innovative, world-leading micro-analytical capability intends to support research of fundamental and strategic problems at the frontiers of the Earth and Environmental Sciences. The facility aims to allow new insight into the age, composition, thermal history and structure of the Australian continent, as necessary for delineating mineral endowment and for tracing the sources of ore ....Laser ablation multiple split streaming. Laser ablation multiple split streaming: This geochemical facility with an innovative, world-leading micro-analytical capability intends to support research of fundamental and strategic problems at the frontiers of the Earth and Environmental Sciences. The facility aims to allow new insight into the age, composition, thermal history and structure of the Australian continent, as necessary for delineating mineral endowment and for tracing the sources of ore metals. It will provide a higher resolution record of climate and environmental change which will better inform assessment of the impacts, both locally and regionally. It is intended that the facility will amplify national and international scientific collaboration and create unique research opportunities for Australian-based scientists.Read moreRead less
