“…Some of the marine records also provide information on what happened on land, including terrestrial pollen records (Harle, 1997), river sediment supply (a proxy for fluvial discharge) and aeolian activity (Hesse, 1994;Gingele et al, 2004;Gingele et al, 2007). The chronology of the selected cores ( Fig.…”

Quaternary Science Reviews, 74 58-77.Climatic records over the past 30 ka from temperate Australia -a synthesis from the Oz-INTIMATE workgroup AbstractTemperate Australia sits between the heat engine of the tropics and the cold Southern Ocean, encompassing a range of rainfall regimes and falling under the influence of different climatic drivers. Despite this heterogeneity, broad-scale trends in climatic and environmental change are evident over the past 30 ka. During the early glacial period (∼30-22 ka) and the Last Glacial Maximum (∼22-18 ka), climate was relatively cool across the entire temperate zone and there was an expansion of grasslands and increased fluvial activity in regionally important Murray-Darling Basin. The temperate region at this time appears to be dominated by expanded sea ice in the Southern Ocean forcing a northerly shift in the position of the oceanic fronts and a concomitant influx of cold water along the southeast (including Tasmania) and southwest Australian coasts. The deglacial period (∼18-12 ka) was characterised by glacial recession and eventual disappearance resulting from an increase in temperature deduced from terrestrial records, while there is some evidence for climatic reversals (e.g. the Antarctic Cold Reversal) in high resolution marine sediment cores through this period. The high spatial density of Holocene terrestrial records reveals an overall expansion of sclerophyll woodland and rainforest taxa across the temperate region after ∼12 ka, presumably in response to increasing temperature, while hydrological records reveal spatially heterogeneous hydro-climatic trends. Patterns after ∼6 ka suggest higher frequency climatic variability that possibly reflects the onset of large scale climate variability caused by the El Niño/Southern Oscillation.

“…In addition to these continent-wide studies, Australian submarine canyons have been mapped at local to regional scales along the southwestern (Von Der Borch, 1968;Exon et al, 2005), south-south-eastern (Hill et al, 1998;Gingele et al, 2004;Hill et al, 2005;Mitchell et al, 2007) and north-eastern (Puga-Bernabeu et al, 2011Webster et al, 2012) margins with a focus on canyon geology, geomorphology and sedimentology. Canyon-specific studies of local patterns in benthic biodiversity (e.g.…”

Classification of submarine canyons of the Australian continental margin

Submarine canyons influence oceanographic processes, sediment transport, productivity and benthic biodiversity from the continental shelf to the slope and beyond. However, not all canyons perform the same function. The relative influence of an individual canyon on these processes will, in part, be determined by its form, shape and position on the continental margin. Here we present an analysis of canyon geomorphic metrics using an updated national dataset of 713 submarine canyons surrounding mainland Australia. These metrics (attributes) for each canyon are used to classify them into canyon types across a hierarchy of physical characteristics separately for shelf-incising (n = 95) and slope-confined (blind; n = 618) canyons. We find that the canyon metrics describe a wide variety of canyon form and complexity that is consistent with a population of canyons that has evolved at different rates around the Australian margin since the break-up of Gondwana. The large number of slopeconfined canyons is interpreted to reflect dominance of slope mass-wasting processes over erosive turbidity flows from fluvial and shelf sources on an arid continent. The distribution of submarine canyons around the Australian margin is not regular, with clusters occurring in the east, southeast, west and southwest where the margin is steepest. The classification result provides a quantitative framework for describing canyon heterogeneity for application in studies of geological controls on individual canyons, canyon oceanography and canyon biodiversity.Crown

“…The interglacial period MIS 5e might have been wetter than other interglacial periods (Harle, 1997;Murray-Wallace et al, 2000Nanson et al, 2003;Gingele et al, 2004), and the resulting increased vegetation may have stabilised the dunes and prevented aeolianite deposition; the lack of aeolianites of MIS 5e age has been noted across southern Australia (Gardner et al, 2006;Lipar and Webb, 2014). The absence of overlying sand and the wetter climate during MIS 5e could have resulted in additional karstification of the Duquesne Member, accounting for the great abundance of the pipes within this member and the fact that they extend deeper, drilling down into underlying member.…”
