Unravelling the history of nitrogen cycling within the central Great Barrier Reef. This project aims to use coral skeleton geochemical analysis to establish if, when, and how nitrogen cycling changed along the central inshore region of the Great Barrier Reef (GBR) lagoon. Increasing anthropogenic nitrogen discharge to coastal waters could drive ecosystem decline in the GBR, one of Australia’s most sensitive and economically valuable natural environments. However, the full effect of anthropogenic ....Unravelling the history of nitrogen cycling within the central Great Barrier Reef. This project aims to use coral skeleton geochemical analysis to establish if, when, and how nitrogen cycling changed along the central inshore region of the Great Barrier Reef (GBR) lagoon. Increasing anthropogenic nitrogen discharge to coastal waters could drive ecosystem decline in the GBR, one of Australia’s most sensitive and economically valuable natural environments. However, the full effect of anthropogenic nitrogen is unclear due to a lack of long, continuous records. This project will unravel the history of nitrogen cycling in the GBR since the mid-1800s, knowledge crucial for managing this reef system.Read moreRead less

Summary
A high-resolution isotope facility for low cost analysis of water, plant, and soil/sediment samples to understand environmental change. The most significant environmental challenges facing Australia include ensuring sustainable management of our water resources and conservation of both terrestrial and marine biodiversity, particularly in the face of our changing climate and land-use. The new instruments will accelerate progress across a number of projects aimed at understanding the developme ....A high-resolution isotope facility for low cost analysis of water, plant, and soil/sediment samples to understand environmental change. The most significant environmental challenges facing Australia include ensuring sustainable management of our water resources and conservation of both terrestrial and marine biodiversity, particularly in the face of our changing climate and land-use. The new instruments will accelerate progress across a number of projects aimed at understanding the development of groundwater resources, the relative dependency of ecosystems on groundwater versus soil and surface water, and an assessment of the likely impacts of altered hydrology, especially dewatering and salinisation, on ecosystems. In addition, they will also be used to extend our knowledge of climate variability in the recent past and increase understanding of critical marine resources.Read moreRead less
Predicting and understanding coccolithophorid calcification in a changing ocean. This project will investigate the entire natural coastal and oceanic coccolithophore assemblages. The least and most sensitive species to ocean change will be examined in innovative laboratory experiments and will enhance the understanding of how species-specific responses translate to the ecosystem level, necessary for predictions of future carbon cycling.
