A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding .... A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding the critical exchanges of water and greenhouse gases (GHGs) combining field methodologies and hydrological models, under different climatic conditions. The intended outcomes will benefit management of GHG emissions, coastal flooding and vulnerable groundwater dependent habitats.Read moreRead less
Social implications of market-based policy instruments for carbon and water. This project aims to analyse socio-cultural benefits and risks in the two significant environmental markets of carbon and water across three sites in Australia and Timor-Leste. Research into market-based policies to manage significant environmental issues is yet to fully consider socio-cultural dimensions. This project intends to document local community producers, distant investor and consumer perspectives, and incorpo ....Social implications of market-based policy instruments for carbon and water. This project aims to analyse socio-cultural benefits and risks in the two significant environmental markets of carbon and water across three sites in Australia and Timor-Leste. Research into market-based policies to manage significant environmental issues is yet to fully consider socio-cultural dimensions. This project intends to document local community producers, distant investor and consumer perspectives, and incorporate these perspectives into methods for improving the operation and impact of these expanding markets. By undertaking the first systematic comparison across resources and sites, the project expects to fill a key gap in environmental scholarship and contribute to international strategies to improve social and environmental outcomes in market-based environmental policy.Read moreRead less
Geological sequestration of carbon dioxide in deep saline aquifers: coupled flow-mechanical considerations. Deep saline aquifers have been routinely proposed as sites for long-term, large-scale storage of carbon dioxide (CO2) emissions, as an option to assist the abatement of global warming. This project investigates expected engineering behaviour of deep saline aquifer reservoirs and their stability following CO2 sequestration.
Building insights of our largest terrestrial carbon sink: rangelands soils. Rangelands soils represent Australia’s largest carbon sink. Yet, little is known about their potential for carbon sequestration or their vulnerability to climate and environmental change. This project leverages investments in national terrestrial observation platforms and integrates previous research outputs to develop new methods to measure and build understanding of soil carbon composition and dynamics in rangeland eco ....Building insights of our largest terrestrial carbon sink: rangelands soils. Rangelands soils represent Australia’s largest carbon sink. Yet, little is known about their potential for carbon sequestration or their vulnerability to climate and environmental change. This project leverages investments in national terrestrial observation platforms and integrates previous research outputs to develop new methods to measure and build understanding of soil carbon composition and dynamics in rangeland ecosystems. Under a framework that connects detailed measurements and small-scale processes, with machine-learning, data-model assimilation and large-scale next-generation biogeochemical modelling, it’ll allow more accurate predictions of soil carbon change and better decision-making to guide sustainable rangelands management.Read moreRead less
When the ice melts: a new perspective on the causes of Quaternary glacial terminations. The project will assemble an unprecedented palaeoclimate time series extending back to 1.2 million years ago that will allow marine and ice core records to be placed onto an absolute time scale. This will allow testing of fundamental hypotheses on why the Earth's climate shifts from glacial to interglacial states, with flow-on effects to climate models.
Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aim ....Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aims to apply novel observational methods, complimented by numerical modelling, to quantify the drivers of recent change. This project expects to transform our ability to predict how ocean temperature and sea level will change in the future.Read moreRead less
Australian climate extremes and predictability in a changing CO2 world: the unique role of the Southern Hemisphere extratropical ocean-atmosphere. Australia's climate is extreme, with harsh droughts, severe bushfire seasons, climate change, soil loss, and salinity all posing potentially enormous socio-economic challenges over the next fifty years. Research into climate variability, extremes, and predictability is thus highly significant for Australia, and will underpin efforts to protect our bio ....Australian climate extremes and predictability in a changing CO2 world: the unique role of the Southern Hemisphere extratropical ocean-atmosphere. Australia's climate is extreme, with harsh droughts, severe bushfire seasons, climate change, soil loss, and salinity all posing potentially enormous socio-economic challenges over the next fifty years. Research into climate variability, extremes, and predictability is thus highly significant for Australia, and will underpin efforts to protect our biodiversity and ensure the nation's environmental sustainability. We propose to launch a major new initiative in extratropical climate analysis. This work will have significant benefits for the many sectors of society reliant on interseasonal-interannual climate prediction. Prominent examples include agriculture, energy, freshwater supply, bushfire control, air quality, health, and tourism.Read moreRead less
Past climate and environmental impacts on Great Barrier Reef paleoecology. This project aims to investigate the interconnected processes that led to past reef growth and demise. The iconic Great Barrier Reef and reefs globally are under threat. Yet reefs appear to have undergone cycles of death and recovery, though the causes are poorly understood. This project will reconstruct past climate, rainfall, water quality, coral bleaching and reef ecology feedbacks across Great Barrier Reef death event ....Past climate and environmental impacts on Great Barrier Reef paleoecology. This project aims to investigate the interconnected processes that led to past reef growth and demise. The iconic Great Barrier Reef and reefs globally are under threat. Yet reefs appear to have undergone cycles of death and recovery, though the causes are poorly understood. This project will reconstruct past climate, rainfall, water quality, coral bleaching and reef ecology feedbacks across Great Barrier Reef death events to establish which environmental stressors and paleoclimate variations are most critical for reef health. The outcomes will better constrain long term coral reef dynamics and provide significant benefits to those who manage reefs globally, since the Great Barrier Reef covers the full range of reef environments.Read moreRead less
