Contrasting Sedimentation Rates In Lake Illawarra And St Georges Basin, Two Large Barrier Estuaries On The Southeast Coast Of Australia, Colin Murray-Wallace, Brian Jones, Craig Sloss, H Heijnis, B Brooke Jun 2013

Contrasting Sedimentation Rates In Lake Illawarra And St Georges Basin, Two Large Barrier Estuaries On The Southeast Coast Of Australia, Colin Murray-Wallace, Brian Jones, Craig Sloss, H Heijnis, B Brooke

B. G. Jones

Sedimentation rates over the last 100 years within two lagoons on the southeast coast of Australia, Lake Illawarra and St Georges Basin, have been quantified to determine the effects of catchment land use change and native vegetation clearance on infill rates, and spatial variations in the rate at which the estuaries have filled. Both catchments have similar lake and catchment area but have experience different degrees of modification due to land clearing for agriculture practices, urbanisation and industrialisation. Results indicate that in the heavily modified catchment of Lake Illawarra sedimentation rates close to fluvial deltas can be in excess of …


Reconstructing Recent Sedimentation In Two Urbanised Coastal Lagoons (Nsw, Australia) Using Radioisotopes And Geochemistry, Brian Jones, H Heijnis, J. Harrison, Suzanne Hollins, S Hankin, Atun Zawadzki Jun 2013

Reconstructing Recent Sedimentation In Two Urbanised Coastal Lagoons (Nsw, Australia) Using Radioisotopes And Geochemistry, Brian Jones, H Heijnis, J. Harrison, Suzanne Hollins, S Hankin, Atun Zawadzki

B. G. Jones

In this study, we combined grain size and geochemical analyses with radioisotope analysis of lead-210 (210Pb), caesium-137 (137Cs) and radiocarbon (14C) ages to reconstruct the sedimentation history of two urbanised coastal lagoons in south-east Australia. Towradgi and Fairy Lagoons were both found to exhibit slow initial sedimentation of less than 1 mm year-1 prior to anthropogenic influences. Land clearing in the catchments increased runoff and erosion in the creeks feeding into the estuaries, and has resulted in progradation of fluvial material into the estuarine systems with a marked increase in sedimentation to between 2 and 7 mm year-1. The upper …

The Sedimentary Record Of Palaeoenvironments And Sea-Level Change In The Gulf Of Carpentaria, Australia, Through The Last Glacial Cycle, Jessica Reeves, Allan Chivas, Adriana Garcia, Sabine Holt, Martine Couapel, Brian Jones, Dionisio Cendon, David Fink Jun 2013

The Sedimentary Record Of Palaeoenvironments And Sea-Level Change In The Gulf Of Carpentaria, Australia, Through The Last Glacial Cycle, Jessica Reeves, Allan Chivas, Adriana Garcia, Sabine Holt, Martine Couapel, Brian Jones, Dionisio Cendon, David Fink

B. G. Jones

Environmental evolution of the Gulf of Carpentaria region, the world's largest tropical epicontinental seaway, through the last glacial cycle has been determined from a series of six sediment cores. These cores form the focus of a multi-disciplinary study to elucidate sea level, climate and environmental change in the region. The sedimentary record reveals a series of facies including open shallow marine, marginal marine, estuarine, lacustrine and subaerial exposure, throughout the extent of the basin during this period. The partial or complete closure of the central basin from marine waters results from sea level falling below the height of one or …


Climate Change In The Dead Heart Of Australia, Joshua Larsen, Gerald C. Nanson, Timothy J. Cohen, Brian G. Jones, John D. Jansen, Jan-Hendrik May Jun 2013

Climate Change In The Dead Heart Of Australia, Joshua Larsen, Gerald C. Nanson, Timothy J. Cohen, Brian G. Jones, John D. Jansen, Jan-Hendrik May

B. G. Jones

Despite the absence of large-scale glaciation, the Australian continent has experienced substantial environmental change throughout the Quaternary period. This is especially pronounced in central Australia, where one seventh of the continent is drained internally to the depocentre, and lowest point in Australia, Lake Eyre (Figure 1). Research has shown that at one time, large sandy braided and meandering rivers carried water through dunefields to a large freshwater lake system. Today, the rivers are hostage to the dunefield, and floodwaters might only reach Lake Eyre once every ten years or so. In order to understand the development of this arid desert …

Continental Aridification And The Vanishing Of Australia's Megalakes, Timothy J. Cohen, Gerald C. Nanson, John D. Jansen, B. G. Jones, Zenobia Jacobs, P Treble, David M. Price, Jan-Hendrik May, A Smith, Linda K. Ayliffe, John C. Hellstrom

B. G. Jones

The nature of the Australian climate at about the time of rapid megafaunal extinctions and humans arriving in Australia is poorly understood and is an important element in the contentious debate as to whether humans or climate caused the extinctions. Here we present a new paleoshoreline chronology that extends over the past 100 k.y. for Lake Mega-Frome, the coalescence of Lakes Frome, Blanche, Callabonna and Gregory, in the southern latitudes of central Australia. We show that Lake Mega-Frome was connected for the last time to adjacent Lake Eyre at 50-47 ka, forming the largest remaining interconnected system of paleolakes on …


Alluvial Evidence For Major Climate And Flow Regime Changes During The Middle And Late Quaternary For Eastern Central Australia, Gerald C. Nanson, David M. Price, B. G. Jones, Jerry C. Maroulis, Maria Coleman, Hugo Bowman, Timothy J. Cohen, Tim Pietsch, Joshua R. Larsen Jun 2013

Alluvial Evidence For Major Climate And Flow Regime Changes During The Middle And Late Quaternary For Eastern Central Australia, Gerald C. Nanson, David M. Price, B. G. Jones, Jerry C. Maroulis, Maria Coleman, Hugo Bowman, Timothy J. Cohen, Tim Pietsch, Joshua R. Larsen

B. G. Jones

As a low-gradient arid region spanning the tropics to the temperate zone, the Lake Eyre basin has undergone gentle late Cenozoic crustal warping leading to substantial alluvial deposition, thereby forming repositories of evidence for palaeoclimatic and palaeohydrological changes from the Late Tertiary to the Holocene. Auger holes and bank exposures at five locations along the lower 500 km of Cooper Creek, a major contributor to Lake Eyre in the eastern part of the basin, yielded 85 luminescence dates (TL and OSL) that, combined wit a further 142 luminescence dates from northeastern Australia, have established a chronology of multiple episodes of …


Late Quaternary Aeolian And Fluvial Interactions On The Cooper Creek Fan And The Association Between Linear And Source-Bordering Dunes, Strzelecki Desert, Australia, Timothy Cohen, Gerald Nanson, Joshua Larsen, B. Jones, David Price, Maria Coleman, Tim Pietsch Jun 2013

Late Quaternary Aeolian And Fluvial Interactions On The Cooper Creek Fan And The Association Between Linear And Source-Bordering Dunes, Strzelecki Desert, Australia, Timothy Cohen, Gerald Nanson, Joshua Larsen, B. Jones, David Price, Maria Coleman, Tim Pietsch

B. G. Jones

The Innamincka Dome and associated low-gradient fan in the Strzelecki Desert is the product of Cenozoic crustal warping that has aided formation of an extensive array of palaeochannels, source-bordering transverse dunes and superimposed linear dunes. These dunes have impeded the course of Cooper Creek and provided a repository of evidence for Quaternary climate change as well as the interactive processes between transverse and linear dune formation. At Turra, Gidgealpa and sites nearby are extensive fluvial and aeolian sand bodies that date from marine isotope stages (MIS) 8-3 and the Last Glacial Maximum (LGM) and are now surrounded or buried by …

Poor Iodine Status And Knowledge Related To Iodine On The Eve Of Mandatory Iodine Fortification In Australia, Heather Yeatman, Karen E. Charlton, Fiona Houweling Apr 2013

Poor Iodine Status And Knowledge Related To Iodine On The Eve Of Mandatory Iodine Fortification In Australia, Heather Yeatman, Karen E. Charlton, Fiona Houweling

Karen E. Charlton

Background: Mandatory fortification of bread with iodised salt is proposed to address the re-emergence of iodine deficiency in Australia and New Zealand. The impacts of fortification require baseline data of iodine status among vulnerable sectors of the population. Objective: To assess the iodine status of healthy women and to investigate consumer understanding and attitudes related to the proposed mandatory iodine fortification programme. Design: Cross-sectional sample of 78 non-pregnant women aged 20-55 y was conveniently sampled in Wollongong, NSW. A single 24-hr urine sample was collected for urinary iodine concentration (UIC). A selfadministered questionnaire assessed consumer understanding, perceptions and attitudes related …

Late-Surviving Megafauna In Tasmania Australia, Implicate Human Involvement In Their Extinction, Christian Turney, T Flannery, Richard Roberts, Craig Reid, Keith Fifield, T Higham, Zenobia Jacobs, Noel Kemp, Eric Colhoun, R.M. Kalin Mar 2013

Late-Surviving Megafauna In Tasmania Australia, Implicate Human Involvement In Their Extinction, Christian Turney, T Flannery, Richard Roberts, Craig Reid, Keith Fifield, T Higham, Zenobia Jacobs, Noel Kemp, Eric Colhoun, R.M. Kalin

Richard G Roberts

Establishing the cause of past extinctions is critical if we are to understand better what might trigger future occurrences and how to prevent them. The mechanisms of continental late Pleistocene megafaunal extinction, however, are still fiercely contested. Potential factors contributing to their demise include climatic change, human impact, or some combination. On the Australian mainland, 90% of the megafauna became extinct by ≈46 thousand years (ka) ago, soon after the first archaeological evidence for human colonization of the continent. Yet, on the neighboring island of Tasmania (which was connected to the mainland when sea levels were lower), megafaunal extinction appears …


A High-Resolution Record Of Vegetation And Climate Through The Last Glacial Cycle From Caledonia Fen, Southeastern Highlands Of Australia, A Kershaw, G Mckenzie, N Porch, Richard Roberts, J Browne, H Heijnis, M Orr, Geraldine Jacobsen, P Newall Mar 2013

A High-Resolution Record Of Vegetation And Climate Through The Last Glacial Cycle From Caledonia Fen, Southeastern Highlands Of Australia, A Kershaw, G Mckenzie, N Porch, Richard Roberts, J Browne, H Heijnis, M Orr, Geraldine Jacobsen, P Newall

Richard G Roberts

A blocked tributary has provided a rare site of long-term sediment accumulation in montane southeastern Australia. This site has yielded a continuous, detailed pollen record through the last ca. 140 000 years and revealed marked vegetation and environmental changes at orbital to sub-millennial scales. Radiocarbon and optically stimulated luminescence (OSL, or optical) ages provide some chronological control for the last ca. 70 000 years. Most of the sediment is inorganic but with well preserved pollen that accumulated under unproductive and probably largely ice-covered lake conditions. The lake was surrounded by low-growing plants with an alpine character. Exceptions include three discrete …

Single-Grain Optical Dating Of Grave-Infill Associated With Human Burials At Lake Mungo Australia, Jonathon Olley, Richard Roberts, Hiroyuki Yoshida, James M Bowler Mar 2013

Single-Grain Optical Dating Of Grave-Infill Associated With Human Burials At Lake Mungo Australia, Jonathon Olley, Richard Roberts, Hiroyuki Yoshida, James M Bowler

Richard G Roberts

Recent age constraints on Australia's oldest human remains (Mungo I and III), found at Lake Mungo in western New South Wales, relied on optical dating of sands from the same stratigraphic units as those into which the remains had been inserted (42±3 ka) and those that overlay the graves (38±2 ka), giving a burial age of 40±2 ka. This indirect means of dating the burials was necessary because the original site from which the remains had been excavated had been completely eroded away. At the time of the original excavation of the Mungo III grave, blocks of sediment from the …

Mapping Same-Sex Couple Family Households In Australia, Andrew Gorman-Murray, Christopher Brennan-Horley, Kirsten Mclean, Gordon Waitt, Christopher Gibson

Christopher R Brennan-Horley

The map (1:1,218,987) accompanying this report is the first to depict the distribution of same-sex couple family households across Australia. The map and the report contribute to emerging scholarship combining critical geographies of sexualities with quantitative techniques and GIS in order to advance the political claims of sexual minorities. The data were collected through the 2006 Census and obtained via consultation with the Australian Bureau of Statistics. These data included the number of same-sex couple family households for all Statistical Divisions across Australia and for Statistical Sub-Divisions within metropolitan capital cities. Geographical concentrations of same-sex couple family households were determined …


The Geography Of Same-Sex Families In Australia: Implications For Regulatory Regimes, Christopher Brennan-Horley, Andrew Gorman-Murray Jan 2013

The Geography Of Same-Sex Families In Australia: Implications For Regulatory Regimes, Christopher Brennan-Horley, Andrew Gorman-Murray

Christopher R Brennan-Horley

Knowledge of the geographical scope of same-sex families is useful in appealing for relationship and family formation rights. This article analyses the geography of same-sex families in Australia through a critical mapping exercise, offering geographical analysis as a means to assist with their human rights claims. While maps have been used to shore up political and legal power, ‘subversive’ maps can visually challenge dominant views and advance minority groups' constitutive and, distributional politics. We utilise 2006 Census data to map the distribution of same-sex couple family households across Australia, including variations by gender and dependent children. Same-sex families are widespread: …


Predicting Avian Distributions To Evaluate Spatiotemporal Overlap With Locust Control Operations In Eastern Australia, Judit K. Szabo, Pamela J. Davy, Michael Hooper, Lee Astheimer Dec 2012

Predicting Avian Distributions To Evaluate Spatiotemporal Overlap With Locust Control Operations In Eastern Australia, Judit K. Szabo, Pamela J. Davy, Michael Hooper, Lee Astheimer

Dr Pamela Davy

Locusts and grasshoppers cause considerable economic damage to agriculture worldwide. The Australian Plague Locust Commission uses multiple pesticides to control locusts in eastern Australia. Avian exposure to agricultural pesticides is of conservation concern, especially in the case of rare and threatened species. The aim of this study was to evaluate the probability of pesticide exposure of native avian species during operational locust control based on knowledge of species occurrence in areas and times of application. Using presence-absence data provided by the Birds Australia Atlas for 1998 to 2002, we developed a series of generalized linear models to predict avian occurrences …


Fractionation Of Sedimentary Arsenic From Port Kembla Harbour, Nsw, Australia, Glennys A. O'Brien, William E. Price, Bryan E. Chenhall, Muhammad Damris Oct 2012

Fractionation Of Sedimentary Arsenic From Port Kembla Harbour, Nsw, Australia, Glennys A. O'Brien, William E. Price, Bryan E. Chenhall, Muhammad Damris

William E. Price

The binding of arsenic in sediments of the heavily industrialised Port Kembla Harbour, NSW, Australia, has been investigated. Both dredge and core samples have been used to develop a sieving/sequential extraction (SE) procedure. Dredge samples included oxic surficial and deeper anoxic sediment. The main core sample analysed was 18 cm deep, sliced at 2 cm intervals. Sediment was sieved to three size ranges (250 microm) and each of these was then subjected to a four step SE, sequentially solubilizing arsenic as ion exchangeable, 1 M HCl soluble, NH(2)OH.HCl soluble, and strong oxidising acid soluble. Concentrations of 50-500 mg As kg(-1) …


Decolonising, Multiplicities And Mining In The Eastern Goldfields, Western Australia, Leah Gibbs Sep 2012

Decolonising, Multiplicities And Mining In The Eastern Goldfields, Western Australia, Leah Gibbs

Leah Maree Gibbs

In this 'postcolonial' era, peoples and places around the globe continue to face ongoing colonisation. Indigenous peoples in particular experience colonisation in numerous forms. Despite recent attempts to 'decolonise' indigenous spaces, hegemonic systems of production, governance and thinking often perpetuate colonial structures and relationships, resulting in further entrenched colonisation or 'deep colonising' (Rose, 1999). The interface between indigenous communities and the mining industry provides fertile ground for the tensions emerging between decolonising and deep colonising. Gold mining operations at Placer Dome's Granny Smith mine in the Eastern Goldfields of Western Australia present a valuable case study for examining this tension. …
