<strong class="journal-contentHeaderColor">Abstract.</strong> We present a database of cosmogenic radionuclide and luminescence measurements in fluvial sediment. With support from the Australian National Data Service (ANDS) we have built infrastructure for hosting maintaining data at University Wollongong making this available to research community via an Open Geospatial Consortium (OGC)-compliant web service.

Abstract Water volume estimates of shallow desert lakes are the basis for water balance calculations, important both resource management and paleohydrology/climatology. volumes typically inferred from bathymetry mapping; however, being shallow, ephemeral, remote, bathymetric surveys scarce in such lakes. We propose a new, remote‐sensing‐based, method to derive using relation between occurrence, during >30 year optical satellite data, accurate elevation measurements new Ice, Cloud, Land...

Abstract. Terrestrial data spanning the Last Glacial Maximum (LGM) and deglaciation from southern Australian region are sparse limited to discontinuous sedimentological geomorphological records with relatively large chronological uncertainties. This dearth of has hindered a critical assessment role Southern Hemisphere mid-latitude westerly winds on region's climate during this time period. In study, two precisely dated speleothem for Mairs Cave, Flinders Ranges, presented, providing first...
Abstract Human disturbance induces significant geomorphic changes to river systems. In eastern Australia, land‐use practices such as clearance of forests and riparian vegetation, removal wood from channels in the 19th 20th centuries induced widespread impacts. However, since 1970s, there has been a noticeable shift condition many rivers New South Wales (NSW). This transition recovery trajectory reflects reduction pressures improved farming on one hand adoption enhancement approaches...
Abstract The peopling of Sahul (the combined continent Australia and New Guinea) represents the earliest continental migration settlement event solely anatomically modern humans, but its patterns ecological drivers remain largely conceptual in current literature. We present an advanced stochastic-ecological model to test relative support for scenarios describing where when first humans entered Sahul, their most probable routes early settlement. supports a dominant entry via northwest Shelf...
Abstract Long-standing interpretations of the Last Glacial Maximum (21,000 ± 2000 years ago) in Australia suggest that period was extremely cold and arid, during which Indo-Australian summer monsoon system collapsed, human populations declined retreated to ecological refuges survive. Here, we use transient iTRACE simulations, combined with palaeoclimate proxy records archaeological data re-interpret late terminal Pleistocene – 11,000 years) Australia. The model suggests climates peak were...
Abstract The degree to which Southern Hemisphere climatic changes during the end of last glacial period and early Holocene (30‐8 ka) were influenced or initiated by events occurring in high latitudes Northern is a complex issue. There conflicting evidence for hemispheric ‘teleconnection’ an unresolved debate as principle forcing mechanism(s). available hypotheses are difficult test robustly, however, because few detailed palaeoclimatic records widely dispersed lack duplication. Here we...
Abstract The timing and duration of the coldest period in last glacial stage, often referred to as maximum (LGM), has been observed vary spatially temporally. In Australia, this is characterised by colder, some places more arid, climates than today. We applied Monte-Carlo change point analysis all available continuous proxy records covering period, primarily pollen records, from across Australia (n = 37) assess change. find a significant occurred (within uncertainty) at 28.6 ± 2.8 ka 25...

Ecological impacts geomorphic changes to structure function throughout are assessed. 2. At time settlement, many water courses discontinuous, with extensive swamps along middle upper courses. Following series direct indirect human impacts, channels became continuous parts catchment, as valley fills at base...
Understanding how sediment transport and storage will delay, attenuate, even erase the erosional signal of tectonic climatic forcings has bearing on our ability to read interpret geologic record effectively. Here, we estimate transit times in Australia's largest river system, Murray-Darling basin, by measuring downstream changes cosmogenic 26Al/10Be/14C ratios modern sediment. Results show that sediments have experienced multiple episodes burial reexposure, with cumulative lag exceeding 1 Ma...
