The Geomorphological Evolution Of A Wave-Dominated Barrier Estuary: Burrill Lake, New South Wales, Australia, Brian G. Jones, Craig R. Sloss, David M. Price, C.E. Mcclennen, John De Carli Jun 2013

The Geomorphological Evolution Of A Wave-Dominated Barrier Estuary: Burrill Lake, New South Wales, Australia, Brian G. Jones, Craig R. Sloss, David M. Price, C.E. Mcclennen, John De Carli

B. G. Jones

The geomorphological evolution of the Holocene wave-dominated barrier estuary at Burrill Lake on the New South Wales coast, Australia, has been delineated using a combination of seismic stratigraphy and the lithostratigraphic analysis of vibracores collected from the back-barrier estuarine environment. A combination of radiocarbon and aspartic acid racemisation-derived ages obtained on Holocene fossil molluscs, and the thermoluminescent signal in remnant Last Interglacial barrier sediments provides the chronological framework for this investigation. Results from this paper show that the barrier estuary occupies a relatively narrow (<1.5 km wide) and shallow (<40 m deep) incised bedrock valley formed during sea-level …

Cyclicity In The Nearshore Marine To Coastal, Lower Permian, Pebbley Beach Formation, Southern Sydney Basin, Australia: A Record Of Relative Sea-Level Fluctuations At The Close Of The Late Palaeozoic Gondwanan Ice Age, Brian G. Jones, Stuart C. Tye, James A. Maceachern, Kerrie L. Bann, Christopher R. Fielding Jun 2013

Cyclicity In The Nearshore Marine To Coastal, Lower Permian, Pebbley Beach Formation, Southern Sydney Basin, Australia: A Record Of Relative Sea-Level Fluctuations At The Close Of The Late Palaeozoic Gondwanan Ice Age, Brian G. Jones, Stuart C. Tye, James A. Maceachern, Kerrie L. Bann, Christopher R. Fielding

B. G. Jones

The Lower Permian (Artinskian to Sakmarian) Pebbley Beach Formation of the southernmost Sydney Basin in New South Wales, Australia, records sediment accumulation in shallow marine to coastal environments at the close of the Late Palaeozoic Gondwanan ice age. This paper presents a sequence stratigraphic re-evaluation of the upper half of the unit based on the integration of sedimentology and ichnology. Ten facies are recognized, separated into two facies associations. Facies Association A (7 facies) comprises variably bioturbated siltstones and sandstones with marine body fossils, interpreted to record sediment accumulation in open marine environments ranging from lower offshore to middle shoreface …

Late Quaternary Mega-Lakes Fed By The Northern And Southern River Systems Of Central Australia: Varying Moisture Sources And Increased Continental Aridity, T Cohen, G Nanson, John Jansen, B Jones, Z Jacobs, J Larsen, J.-H May, P Treble, D Price, A Smith

B. G. Jones

Optically stimulated and thermoluminescence ages from relict shorelines, along with accelerator mass spectrometer 14C ages from freshwater molluscs reveal a record of variable moisture sources supplied by northern and southern river systems to Lake Mega-Frome in southern central Australia during the late Quaternary. Additional lacustrine, palynological and terrestrial proxies are used to reconstruct a record that extends back to 105 ka, confirming that Lakes Mega-Frome and Mega-Eyre were joined to create the largest system of palaeolakes on the Australian continent as recently as 50-47 ka. The palaeohydrological record indicates a progressive shift to more arid conditions, with marked drying after …


Use Of 210pb And 137cs To Simultaneously Constrain Ages And Sources Of Post-Dam Sediments In The Cordeaux Reservoir, Sydney, Australia, Ava Simms, Colin Woodroffe, Brian Jones, H Heijnis, Rob Mann, J. Harrison Jun 2013

Use Of 210pb And 137cs To Simultaneously Constrain Ages And Sources Of Post-Dam Sediments In The Cordeaux Reservoir, Sydney, Australia, Ava Simms, Colin Woodroffe, Brian Jones, H Heijnis, Rob Mann, J. Harrison

B. G. Jones

Environmental radionuclides can be employed as tracers of sediment movement and delivery to water bodies such as lakes and reservoirs. The chronologies of sediments that have accumulated in the Cordeaux reservoir in Sydney, Australia, were determined by the rate of change of 210Pbex with depth and indicate slow accretion in the reservoir. The ratio of enrichment of radionuclides in sediment cores to 210Pbex and 137Cs concentrations in a reference soil sample within the Cordeaux catchment indicates that the dominant source of sediment in the Cordeaux reservoir is surface erosion (detachment and removal of sediment at depths less than 30 cm). …


On The Possible Origins Of An Unusual (Mid To Late Holocene) Coastal Deposit, Old Punt Bay, South-East Australia, Brian Jones, Adam Switzer, S Haslett, Dale Dominey-Howes, D Everett, C Courtney, B Mamo, L Strotz Jun 2013

On The Possible Origins Of An Unusual (Mid To Late Holocene) Coastal Deposit, Old Punt Bay, South-East Australia, Brian Jones, Adam Switzer, S Haslett, Dale Dominey-Howes, D Everett, C Courtney, B Mamo, L Strotz

B. G. Jones

An unusual coarse, shelly sedimentary unit is found elevated above present mean sea level in a sheltered pocket embayment at Old Punt Bay in south-eastern Australia. The coarse sediments, diverse microfauna, and large shelly macrofauna of mixed affinity suggest that the deposit is the result of high-energy deposition. The deposit was previously thought to have been deposited 1000-1300 cal bp based on one shell dated using 14C and amino acid racemisation. However, additional 14C dating indicates a likely age of ~2500 cal bp. Regardless of age constraints, the presence of rock-encrusting oyster shells and large articulated bivalves, suggests that the …


Aeolian-Fluvial Interaction: Evidence For Late Quaternary Channel Change And Wind-Rift Linear Dune Formation In The Northwestern Simpson Desert, Australia, Gerald C. Nanson, Brian G. Jones, David M. Price, Tim Pietsch, C Bristow, Cameron B. Hollands Jun 2013

Aeolian-Fluvial Interaction: Evidence For Late Quaternary Channel Change And Wind-Rift Linear Dune Formation In The Northwestern Simpson Desert, Australia, Gerald C. Nanson, Brian G. Jones, David M. Price, Tim Pietsch, C Bristow, Cameron B. Hollands

B. G. Jones

In central Australia the most easterly extent of the MacDonnell Ranges borders the northwestern Simpson Desert where widely spaced strike ridges intercept the regional linear dunefield. Topographic basins have disrupted regional drainage lines and isolated dune sets from the main dunefield. In the western part of Camel Flat basin large, red coloured linear dunes of fine sand, ~ 74 ka and older, are oriented almost due north. Through gaps in the ranges the Todd River traversed the eastern part of the basin until ~25 ka when it apparently avulsed ~25 km eastwards to its present position. Subsequently, linear dunes, smaller, …


Patterns And Rates Of Sedimentary Infill In The Minnamurra River Estuary, South-Eastern Australia, K Panayotou, Colin Woodroffe, Brian Jones, Bryan Chenhall, Errol Mclean, H Heijnis Jun 2013

Patterns And Rates Of Sedimentary Infill In The Minnamurra River Estuary, South-Eastern Australia, K Panayotou, Colin Woodroffe, Brian Jones, Bryan Chenhall, Errol Mclean, H Heijnis

B. G. Jones

This paper presents a revised process-based model that explores aspects of estuarine geomorphology and the rates and patterns of sedimentary infill based upon the Minnamurra River estuary, a mature barrier estuary in south-eastern Australia. The Minnamurra River is located on the south coast of New South Wales and is characterised by three main facies: a marine flood tide delta/barrier, a central lagoon/estuary and a fluvial delta. The sedimentary record in this system was examined in detail to quantify the rate of estuarine infill. This predominantly infilled mature barrier estuary is now largely dominated by river influence. In the early stages …

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 …


Assessing Soil Remobilisation In Catchments Using A 137 Cs-Sediment Hillslope Model, Ava D. Simms, Colin D. Woodroffe, Brian G. Jones, Henk Heijnis, Jennifer Harrison, Rob Mann Jun 2013

Assessing Soil Remobilisation In Catchments Using A 137 Cs-Sediment Hillslope Model, Ava D. Simms, Colin D. Woodroffe, Brian G. Jones, Henk Heijnis, Jennifer Harrison, Rob Mann

B. G. Jones

Soil redistribution studies are important, especially in water supply catchments, because the rate at which denudation is occurring has implications for offsite water quality. However, the extent to which soil is redistributed within the landscape can be difficult to determine. This challenge can be overcome using fallout caesium-137 (137Cs). This paper describes the rates of soil loss and remobilisation in two sub-catchments within the Sydney Basin region, namely Kembla and Kentish Creeks, which drain to the Cordeaux reservoir. The total inventories of 137Cs in catchment soils were determined, a 137Cs-regression equation and a theoretical diffusion and migration model were used …

Investigation Of Large-Scale Washover Of A Small Barrier System On The Southeast Australian Coast Using Ground Penetrating Radar, Brian G. Jones, C Bristow, Adam D. Switzer Jun 2013

Investigation Of Large-Scale Washover Of A Small Barrier System On The Southeast Australian Coast Using Ground Penetrating Radar, Brian G. Jones, C Bristow, Adam D. Switzer

B. G. Jones

Prehistoric depositional signatures for large-scale washover involving marine inundation events such as storm and tsunami have been the subject of considerable research over the last 15 years. Much of this research has focused on the identification of sand sheets in back-barrier environments as depositional records for extreme washover events. All these deposits must have a sediment source, and by their nature, the most likely source of sediment for washover into back-barrier environments is the barrier itself. This study identifies an erosional signature for large-scale washover from a small coastal barrier on the southeast Australian coast. A distinct lense of marine …

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

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 …

Response Of Coral Reefs To Climate Change: Expansion And Demise Of The Southernmost Pacific Coral Reef, Colin D. Woodroffe, Brendan P. Brooke, Michelle Linklater, David M. Kennedy, Brian G. Jones, Cameron Buchanan, Richard Mleczko, Quan Hua, Jian-Xin Zhao Jun 2013

Response Of Coral Reefs To Climate Change: Expansion And Demise Of The Southernmost Pacific Coral Reef, Colin D. Woodroffe, Brendan P. Brooke, Michelle Linklater, David M. Kennedy, Brian G. Jones, Cameron Buchanan, Richard Mleczko, Quan Hua, Jian-Xin Zhao

B. G. Jones

Coral reefs track sea level and are particularly sensitive to changes in climate. Reefs are threatened by global warming, with many experiencing increased coral bleaching. Warmer sea surface temperatures might enable reef expansion into mid latitudes. Here we report multibeam sonar and coring that reveal an extensive relict coral reef around Lord Howe Island, which is fringed by the southernmost reef in the Pacific Ocean. The relict reef, in water depths of 25-50 m, flourished in early Holocene and covered an area more than 20 times larger than the modern reef. Radiocarbon and uranium-series dating indicates that corals grew between …
