Investigating the controls on the extent of tidewater glaciers. This project aims to improve our ability to model tidewater glaciers. The project will conduct studies of two iconic glacial systems in Alaska: Glacier Bay and Columbia Glacier. These glaciers have recently experienced rapid retreat and contributed to sea level rise. In particular, the Grand Pacific Glacier has retreated 100 kilometres up Glacier Bay, the greatest recorded glacier retreat in the last 200 years. The project will use ....Investigating the controls on the extent of tidewater glaciers. This project aims to improve our ability to model tidewater glaciers. The project will conduct studies of two iconic glacial systems in Alaska: Glacier Bay and Columbia Glacier. These glaciers have recently experienced rapid retreat and contributed to sea level rise. In particular, the Grand Pacific Glacier has retreated 100 kilometres up Glacier Bay, the greatest recorded glacier retreat in the last 200 years. The project will use geomorphic mapping, dating and climate reanalysis to better understand the long term behaviour of these glaciers and the drivers of recent retreat. An expected outcome from the project is a better understanding of the long term behaviour of tidewater glaciers and an improvement in our ability to predict sea level rise from them.Read moreRead less
Global climate change and coastal landscape evolution in southern Australia. This project aims to reconstruct environmental changes that occurred in southern Australia during a geologically recent time interval termed the Early-Middle Pleistocene Transition (1.2 million to 700 thousand years ago) and an interglacial period some 400,000 years ago. Using innovative geochronological, geochemical and modelling techniques, the environmental changes that shaped modern Australian coastal landscapes, in ....Global climate change and coastal landscape evolution in southern Australia. This project aims to reconstruct environmental changes that occurred in southern Australia during a geologically recent time interval termed the Early-Middle Pleistocene Transition (1.2 million to 700 thousand years ago) and an interglacial period some 400,000 years ago. Using innovative geochronological, geochemical and modelling techniques, the environmental changes that shaped modern Australian coastal landscapes, including the intensification of aridity and their timing will be examined. The project will yield new knowledge about the sensitivity of landscapes to current and ongoing environmental changes and derive explanatory models of the rates and characteristics of landscape response to assist future coastal environmental management.Read moreRead less
Climate extremes and landscape responses across continental Australia. This project aims to determine the magnitude, frequency and duration of dry and wet extremes across the Australian continent over the last thousand years and examine landscape responses to such climate extremes. Using terrestrial records from key lake locations, the project expects to construct a record of mega-lakes and mega-droughts and determine whether such climatic phenomena are becoming more frequent or severe through t ....Climate extremes and landscape responses across continental Australia. This project aims to determine the magnitude, frequency and duration of dry and wet extremes across the Australian continent over the last thousand years and examine landscape responses to such climate extremes. Using terrestrial records from key lake locations, the project expects to construct a record of mega-lakes and mega-droughts and determine whether such climatic phenomena are becoming more frequent or severe through time. The project will develop palaeoclimatic data at sub-centennial resolution, examining the spatial coherence of the climate extremes. The project will integrate this with both the historical record and global climate modelling, allowing us to assess the dominant oceanographic and atmospheric conditions that lead to such extremes.Read moreRead less

Summary
High-resolution ITRAX XRF core scanning facility for global change research. This facility will enable researchers to obtain high-resolution geochemical profiles in the study of environmental change and climate variability. It will provide archive data on the variation of density and chemical element composition along sediment and soil cores, rock cores, wood samples, speleothems and corals. These archives contain important information such as human activity, climate variability, water quality c ....High-resolution ITRAX XRF core scanning facility for global change research. This facility will enable researchers to obtain high-resolution geochemical profiles in the study of environmental change and climate variability. It will provide archive data on the variation of density and chemical element composition along sediment and soil cores, rock cores, wood samples, speleothems and corals. These archives contain important information such as human activity, climate variability, water quality changes, pollution histories, recent geomorphological change, land-use change, introduction of invasive species and the occurrence of bushfires. A better understanding of the occurrence and timing of these major environmental issues is of national and regional importance.Read moreRead less

Summary
Single-grain optically-stimulated luminescence and dosimetry instruments to service the Sydney metropolitan and greater New South Wales region. This equipment will support projects that address significant environmental challenges in Australia, such as climate change and variability, coastal management and sustainable river and water management, and that assess the impacts and consequences of these challenges for populations living in environmentally sensitive areas. These projects will build on ....Single-grain optically-stimulated luminescence and dosimetry instruments to service the Sydney metropolitan and greater New South Wales region. This equipment will support projects that address significant environmental challenges in Australia, such as climate change and variability, coastal management and sustainable river and water management, and that assess the impacts and consequences of these challenges for populations living in environmentally sensitive areas. These projects will build on established collaborations in Australia, Antarctica and the south-west Pacific and encourage new collaborations with south-east Asian, Egyptian and Argentinean researchers, which will promote Australian research on a world stage. The use of this equipment will also pioneer new dating methodologies to further enhance Australia's place at the forefront of geochronology.Read moreRead less
