Summary
A mass spectrometer to analyse carbonate isotope records of Australia's climate, soil and groundwater history. Water is a critical resource in Australia, yet there is a fundamental lack of knowledge about the causes and timing of groundwater recharge in the past. This facility will allow researchers to better understand climate and groundwater interactions through high resolution isotope analysis of deposits, such as cave stalagmites and marine corals.

Summary
Resolving nutrient groundwater exports versus soil burial in mangroves. This project aims to examine the role of mangroves in the sequestration and burial of nutrients. Coastal areas increasingly receive enriched nutrient loads, driving anthropogenic eutrophication. Mangrove wetlands naturally filter and bury large quantities of nutrients through soil accretion. This project aims to quantify nutrient groundwater export as related to mangrove soil nutrient retention and determine if these wetland ....Resolving nutrient groundwater exports versus soil burial in mangroves. This project aims to examine the role of mangroves in the sequestration and burial of nutrients. Coastal areas increasingly receive enriched nutrient loads, driving anthropogenic eutrophication. Mangrove wetlands naturally filter and bury large quantities of nutrients through soil accretion. This project aims to quantify nutrient groundwater export as related to mangrove soil nutrient retention and determine if these wetlands have the potential to provide negative feedback to coastal eutrophication. The project plans to use state-of-the-art radionuclide tracer technology to quantify the relationship between groundwater discharge and historical soil nutrient retention.Read moreRead less
Coastal wetlands: are our valuable carbon sinks vulnerable? Saline coastal wetlands store large amounts of carbon and are potentially the most efficient sinks of carbon amongst natural ecosystems. This project will use isotopic tracers to quantify carbon retention within saline coastal wetlands in southeastern Australia, establish the vulnerability of these wetlands to sea-level rise using estimates of sediment accretion and surface elevation change, and use this information to predict the distr ....Coastal wetlands: are our valuable carbon sinks vulnerable? Saline coastal wetlands store large amounts of carbon and are potentially the most efficient sinks of carbon amongst natural ecosystems. This project will use isotopic tracers to quantify carbon retention within saline coastal wetlands in southeastern Australia, establish the vulnerability of these wetlands to sea-level rise using estimates of sediment accretion and surface elevation change, and use this information to predict the distribution of saline coastal wetlands and estimate the carbon sequestration potential of coastal wetlands within a ‘low-carbon economy’. This project will remove impediments to the proper economic evaluation of saline coastal wetlands and enable restoration coastal wetlands to be used to offset carbon emissions.Read moreRead less
