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

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, …


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

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

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

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 …
