A continental perspective on the timing of environmental change during the last glacial stage in Australia
The timing and duration of the coldest period in the last glacial stage, often referred to as the last glacial maximum (LGM), has been observed to vary spatially and temporally. In Australia, this period is characterised by colder, and in some places more arid, climates than today. We applied Monte-Carlo change point analysis to all available continuous proxy records covering this period, primarily pollen records, from across Australia (n = 37) t…

Holocene Vegetation and Paleoclimatic and Paleomagnetic History from Lake Johnston, Tasmania
Lake Johnston cirque contains some of the best subalpine rainforest in Tasmania. Pollen from the sediments shows Lagarostrobos franklinii , which presently reaches 1040 m, may be a glacial relict. Nothofagus cunninghamii–Nothofagus gunnii subalpine rainforest developed between 9000 and 6000 14 C yr B.P., with a maximum at 8700 14 C yr B.P. After 6000 14 C yr B.P. Nothofagus gunnii became more important, and from 3600 14 C yr B.P. sclerophyll and …

Studies of Cainozoic environmental change in Tasmania and coastal East Antarctica
Observational studies on Cainozoic environmental changes in both Tasmania and East Antarctica have led to important modifications in the accepted interpretation of the history of glaciation for each area. Many contributors have played an important role in the processes of investigation leading to the present state of knowledge. A crucial role has been played by the integration of the methods of glacial geomorphology, stratigraphy, sedimentology a…
Quaternary Organic Deposit from Newton Creek Valley, Western Tasmania
Pollen and macrofossils from an organic deposit probably 44 ka BP in age record subalpine heath with abundant local Athrotaxis cupressoides. This was succeeded by subalpine heath that included Casuarina, Phyllocladus and Eucalyptus. The pollen/vegetation assemblages are comparable with present subalpine vegetation located between 850–1050 m, though the site is at 550 m and potentially below the limit of temperate rainforest (620 m). It is inferre…
Late glacial and Holocene vegetation history at Poets hill lake, western Tasmania
Pollen analysis of 3.25 m of late glacial and Holocene sediments gives a mid‐altitude (600 m) record of vegetation development after the last or Margaret Glaciation. Alpine herbfield, coniferous heath and Nothofagus gunnli scrub developed on the moraines until 11,400 BP. Wet montane forest and heath then developed with Phyllocladus aspleniifolius, Nothofagus cunninghamii and Eucalyptus until c. 10,000 BP. After 10,000 BP a mosaic of N. cunningham…
Pleistocene glaciation of the King Valley, Western Tasmania, Australia
Analysis of the geomorphology, geology, and palynology of deposits in the King Valley permits the identification of four glaciations and two interglaciations and has led to a revision of the Pleistocene stratigraphy of the West Coast Range. The oldest late-Cenozoic deposits in the valley appear to predate glaciation, contain extinct pollen types, and are probably of late-Tertiary age. Overlying deposits of the Linda Glaciation show intense chemic…
Geological evidence for changes in the East Antarctica ice sheet (60°–120°E) during the last glaciation
The East Antarctica ice sheet advanced onto the continental shelf during the last glaciation but appears to have been thinner (
Late Glacial and Holocene Vegetation History at Dublin Bog North‐Central Tasmania
Percentage and influx pollen analyses of a 9.17 m core from Dublin Bog give a post last glaciation vegetation history (‐13.6 to 0 ka BP) for the upper Mersey Valley. Herbaceous vegetation of Gramineae, Compositae and Chenopodiaceae developed rapidly after deglaciation and lasted until 13.2 ka BP. Around 13 ka BP Eucalyptus woodland and forest developed rapidly on the valley floor. At the same time Pomaderris apetala became an important understore…
Subglacial Meltwater Channels at Cape Jones, Obruchev Hills, Antarctica
Subglacial curved and winding meltwater channels, and Sichelwannen are recorded from Cape Jones in the Obruchev Hills. Such channels, sometimes referred to as P‐forms, may have a variety of origins. After briefly considering the origins, it is deduced that those at Cape Jones were formed subglacially while the ice surface of the Denman Glacier became lower and bedrock was exposed The presence of water‐laid glacial deposits on the summit of Cape J…
Former glacial lakes of the Bunger Hills, Antarctica
The Bunger Hills in East Antarctica occupy a land area of approximately 400 km2. They have been exposed by Holocene retreat of the Antarctic ice sheet and its outlet glaciers. The accompanying sea level rise flooded the marine inlets that now separate the northern islands and peninsulas from the major part of the hills. During deglaciation the continental ice sheet margin retreated south‐eastwards with several temporary halts, during which ice‐da…
Glacial Stratigraphy of the Upper Mersey Valley, Tasmania
The upper Mersey Valley was glaciated on three occasions during the Pleistocene. The youngest, Rowallan Claciation, probably commenced after 28000 years B.P. The maximum ice limit was attained before 13500 years B.P., and retreat occurred before 10000years B.P. Deposits associated with Rowallan Glaciation are weakly weathered chemically. They overlie moderately weathered deposits that were formed during the Arm Glaciation, which is inferred from …

Stratigraphy, pollen analysis and paleoclimatic interpretation of Mowrray and Rroadmeadows Swamps, North Western Tasmania
Sedimentary, palynologic and 14C analysis of marls and swamp‐peats, formed under fluctuating artesian spring conditions, provide climate and vegetation records from >52,000 to 0 yr BP at Mowbray, and 30,000 to 0 yr BP at Broadmeadows. Before about 65,000 yr BP conditions at Mowbray were relatively dry and the vegetation was Leptospermum shrubland. After 65,000 and before 55,000 yr BP moist conditions produced Cyperaceae swamps. Between 55,000 and…
Glaciations of the West Coast Range, Tasmania
Geomorphic, stratigraphic, palynologic and 14 C evidence indicates that the West Coast Range, Tasmania, was glaciated at least three times during the late Cenozoic. The last or Margaret Glaciation commenced after 30,000 yr B.P., culminated about 19,000 yr B.P., and ended by 10,000 yr B.P. During this period a small ice cap, ca. 250 m thick, and cirque and valley glaciers covered 108 km 2 . The glacial deposits show little chemical weathering or e…
Stratigraphy, Pollen Analysis, and Paleoclimatic Interpretation of Pulbeena Swamp, Northwestern Tasmania
Sedimentary, palynologic, and 14 C analysis of 480 cm of freshwater marl and swamp-peat deposits, formed under the influence of fluctuating artesian springs, provides a paleoenvironmental and paleoclimatic record of approximately 65,000 yr for northwestern Tasmania. The Holocene (Pollen Zone 1, 11,000-0 yr B.P.) climate was warm and moist, and forest vegetation was dominant throughout the area. During the later part of the last glacial stage (Pol…
Stone Fish-Traps at Cooks Corner, Freycinet Peninsula, Eastern Tasmania
Stone fish-traps are not common in Tasmania but some have been recorded recently from Ordinance Point in western Tasmania and between Rocky Cape and Low Head on the northern Tasmanlan coastline (Stockton 1982). In view of the fact that Tasmanlan Aborigines were known to have included several varieties of inshore fish species in their diet prior to 3500 years ago, after which they mysteriously seem to have dropped fish from their diet (Jones 1978)…
