“…Estuarine and near-coastal records from southern WA suggest a relatively dry climate at ~6-4 ka (Semeniuk and Searle, 1985;Semeniuk, 1986;Yassini and Kendrick, 1988), although these data do not correlate well and the inferred climate changes are relatively minor. Vegetation reconstructions from southern WA (which at the time of publication has only Holocene pollen records) show extensive spatial variability between sites.…”

For example, ostracods have been used extensively as proxies for palaeosalinity in both freshwater and marine environments (De Deckker, 1982;Chivas et al, 1985b;Chivas et al, 1986a;Yassini and Kendrick, 1988). The longest ostracod records are from the Victorian sites Tower Hill (D'Costa et al, 1989) and Lake Wangoom (Edney et al, 1990).…”

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.

“…Several studies of Australian estuarine foraminifera have been published, e.g., on Oyster Harbour (McKenzie, 1962), Port Hacking (Albani, 1968a), Blackwood River Estuary (Quilty, 1977), Gippsland Lakes (Apthorpe, 1980), Port Darwin (Michie, 1987), Exmouth Gulf (Haig, 1997), Leschenault Inlet (Revets, 2000), Joseph Bonaparte Gulf (Clarke and others, 2001), and more generally in eastern Australia (Yassini and Jones, 1995). In addition, there are numerous unpublished theses (e.g., Harris, 1968;Cotter, 1980;Stevens, 1989) which constitute significant data repositories.…”

“…In recent years, there have been major efforts to integrate available information into systematic accounts relating foraminiferal distributions with physical and biological parameters. The main compilations relevant to Australasian foraminifera are those by Yassini and Jones (1995) and Hayward and others (1999).…”
