Some Notes on the Principle Cave Areas in Tasmania, 1956, Brown F. R.

A Brief Biography of Tasmanian Caves, 1956, Shaw T. R.

Water Sampling at Yarrangobilly, New South Wales, 1963, Jennings, J. N.

Various geomorphologists such as Bgli, Corbel and Lehmann have in recent years demonstrated the interest that certain simple chemical analyses of natural waters can have for the comparison of rates of limestone solution in different in different climatic conditions. They can also have their relevance for the tracing of underground water connections as Oertli (1953) has shown in the example of the Slovenian part of the classical Yugoslavian karst. Since 1957, the writer has therefore been making such analyses of waters from Australian limestone areas. The chief significance of these measurements comes when one caving area is compared with another. M.M. Sweeting (1960) has already commented briefly on observations from Mole Creek, Tasmania, Buchan, Victoria and the Fitzroy Basin, Western Australia, made in 1958-59 by herself and the writer; further discussion will appear in a forthcoming publication of ours on the Limestone Ranges of the Fitzroy Basin. Nevertheless measurements of this kind can have a certain intrinsic interest as it is hoped to show in the following notes on the few observations I made at Yarrangobilly. These observations are set out in tabular and Trombe graph forms; the locations of the collecting points are shown on the map.

Subterranean occurrence of Anaspides tasmaniae (Thomson) (Crustacea, Syncarida)., 1965, Williams W. D.
Anaspides tasmaniae is recorded from a subterranean habitat for the first time. The only difference noted from surface forms was the smaller amount of pigment present.

Discovery of a Thylacine (Tasmanian Tiger) Carcase In a Cave Near Eucla, Western Australia, 1967, Lowry David C. , Lowry Jacoba W. J.

A well preserved carcase of a Tasmanian tiger (Thylacinus) was found in October, 1966, in Thylacine Hole (N63), a cave 68 miles west of Eucla in Western Australia.

Cockroaches (Blattodea) From Australian Caves, 1967, Richards, Aola M.

Ten species of Australian cockroaches are recorded from Australian caves and mines. Most are troglophiles or guanobia. Only one troglobitic species is known. The distribution of these species is given, and attention is drawn to their absence from south-eastern Australia and Tasmania. It is suggested that climatic changes in the Pleistocene and early Recent may have been responsible for this, and that the fauna found in many cave areas may be of comparatively recent origin.

Tasmanian Cave Fauna: Character and Distribution, 1967, Goede, A.

The geology and nature of the caves is discussed. Cave development has been affected by glacial outwash and periglacial conditions which must be taken into account when considering the development and distribution of cave fauna. The food supply in the caves is limited by the absence of cave-inhabiting bats. Floods while adding to the food supply must be destructive to some forms of terrestrial cave life. The cave fauna consists entirely of invertebrates. The carab genus Idacarabus Lea contains the only troglobites found in Tasmania. A common troglophile throughout the island is Hickmania troglodytes (Higgins and Petterd) which belongs to a very small group of relict spiders. Five species of cave crickets are known from Tasmania and Flinders Island. Three species belong to the genus Micropathus Richards and show an interesting distribution pattern. A single species of glow-worm, Arachnocampa (Arachnocampa) tasmaniensis Ferguson occurs in a number of Tasmanian caves. It is more closely related to the New Zealand species than to glow worms found on the Australian mainland. Other terrestrial cave life is briefly discussed. Aquatic cave life is poorly known. The syncarid Anaspides tasmaniae (Thomson) has been recorded from several caves. It differs from epigean forms in reduction of pigment.

Hydrological Observations at the Junee Resurgence and a Brief Regional Description of the Junee Area, Tasmania, 1973, Goede, A.

The results are presented for one year of field measurement and analysis of water samples at the Junee resurgence, one of the largest karst risings in Tasmania. The water emerges from Junee Cave at an altitude of approximately 300m and forms the source of the Junee River at a point about 5km north-west of the township of Maydena. The resurgence drains a large area along the southern boundary of the Mt Field National Park and appears to be fed by a number of streamsinks, the nearest of which are at least 2km distant. The only underground drainage connection proved so far is with one of the largest of these stramsinks, Khazad-dum. This cave has been explored to a depth of 321m and is recorded as Australia's deepest cave system. The Junee area is located in central southern Tasmania and is centred on 146°40' East and 42°45' South. The Junee resurgence is the only significant rising in the area and is commonly thought to drain most of the Junee area. This opinion is based largely on the interpretation of the geological structure as shown in the geological sketch map of Hughes and Everard (Hughes 1957). However, a more detailed examination of the area on which Figure 1 is based, suggests that the western limit of underground drainage towards the Junee resurgence may be more or less coincident with the axis of the NNW plunging Nichols Spur anticline. Further mapping of the geological structure, and water tracing, will be required to confirm this.

Investigations into the watertightness of the proposed Gordon-above-Olga hydro-electric storage South-west Tasmania, 1974, Roberts Glyn T. , Andric Miodrag,
The Gordon-above-Olga scheme is one of several major hydro-electric developments under investigation in the south-west of Tasmania. The proposed storage area includes a zone of Palaeozoic limestone forming part of the eastern limb of a synclinal structure which provided a potential for the existence of leakage paths capable of threatening the viability of the scheme. The geology of the area is described and the methods used in assessing the likelihood of existence of subjacent karst are detailed. The conclusion is drawn on several grounds that neither recent nor ancient activity is likely to have markedly affected the limestone through the synclinorium. In consequence the water-tightness of the proposed reservoir is predicted

On the Subterranean Syncarids of Tasmania, 1977, Lake P. S. , Coleman D. J.

The current knowledge on the occurrence of syncarid crustaceans in underground habitats in Tasmania is reviewed. The "mountain shrimp" Anaspides tasmaniae has been recorded on at least five occasions from caves. Syncarid shrimps in the genera Allenaspides, Koonunga and Nicraspides have been collected from crayfish burrows. The term Pholeteros is coined to define the community of organisms dwelling in crayfish burrows. Syncarids in the genera Koonunga and Atopobathynella have been collected in the bed of streams (Hyporheos). The collection of the new species of syncarid from an underground spring at Devonport is reported.

Sea Caves of King Island, 1979, Goede Albert, Harmon Russell, Kiernan Kevin

Investigation of two King Island sea caves developed in quartzitic rocks shows them to contain a wealth of clastic and chemical sediments. Clastic sediments consist of wave-rounded cobbles, debris cones, and angular rock fragments produced by frost weathering and crystal wedging. Chemical deposits include a variety of calcium carbonate speleothems and also gypsum occurring as wall crusts and blisters. The latter appear to be a speleothem type of rare occurrence. Growth of gypsum is responsible for some crystal wedging of the bedrock. Three basal stalagmite samples have been dated by the Th/U method indicating Late Pleistocene as well as Holocene speleothem growth. The caves are believed to have formed by preferential wave erosion during the Last Interglacial in altered and fractured quartzites. The evidence for pre-Holocene evolution of sea caves and geos in the Tasman region is summarised. Tasmania and the Bass Strait Islands provide a particularly favourable environment for the preservation of relict landforms on rocky coasts because of Late Quaternary uplift. The potential of further studies of sea caves to test two recently advanced archaeological hypotheses is discussed.

Variation of Hardness in Cave Drips at Two Tasmanian Sites, 1981, Goede, Albert

Thirteen consecutive monthly samples were collected from two drip sites at each of two Tasmanian caves: Little Trimmer at Mole Creek and Frankcombe Cave in the Florentine Valley. At one of the two drip sites in Little Trimmer a positive relationship was found between the logarithm of precipitation and the total hardness without any detectable lag effect. No such relationship was detected at the other drip site despite its close proximity. At both drip sites the hardness values fail to show a seasonal pattern and are clearly unrelated to surface temperature variations. In strong contrast both drip sites in Frankcombe Cave showed significant seasonal variation and close positive correlation with mean monthly temperature with lag times of one and two months respectively. At one of the two drip sites the influence of monthly precipitation on variations in drip hardness could also be detected. The strong temperature dependence of cave drip hardness values at these sites may well be due to soil exposure to direct insolation following recent clearfelling and burning of vegetation in the area.

Isotopic composition of precipitation, cave drips and actively forming speleothems at three Tasmanian cave sites., 1982, Goede A. , Green D. C. , Harmon R. S.

Glaciation and Karst in Tasmania: Review and Speculations, 1982, Goede Albert , Harmon Russell, Kiernan Kevin

The evolution of Tasmanian karsts is fundamentally interwoven with the history of Quaternary climatic change. Specifically karstic processes were periodically overwhelmed by the influence of cold climate which exerted strong controls over thermal, hydrological and clastic regimes. While these episodes of cold climatic conditions have temporally dominated the Quaternary, their legacy may be under represented in present karst landforms. There is no general case with respect to the consequences for karst of the superimposition or close proximity of glacial ice. The pattern of events in each area will be dependant upon the interaction between local and zonal factors. A number of Tasmanian karst which may have been influenced by glaciation are briefly discussed.

Isotopic Composition of Precipitation, Cave Drips and Actively Forming Speleothems at Three Tasmanian Cave Sites, 1982, Goede A. , Green D. C. , Harmon R. S.

Monthly samples of precipitation and cave drips were collected from three Tasmanian cave sites along a north-south transect and their 18O/16O ratios determined. At one station D/H ratios were also measured and the relationship between delta 18O and delta D values investigated. The 18O/16O and D/H ratios of monthly precipitation show marked seasonality with values correlating strongly with mean monthly temperatures. The effect of temperature on 18O/16O ratios appears to increase as one goes southwards and is at least twice as strong at Hastings (.61 deg /oo SMOW/ deg C) as it is shown at Mole Creek (.28 deg /oo SMOW/ deg C). Irregularities in the seasonal pattern of 18O/16O change are particularly pronounced at Hastings and in the Florentine Valley and can be attributed to the amount effect. For delta 18O values > -5.5 deg /oo the combined data from the three Tasmanian stations show an amount effect of .026 deg /oo SMOW/mm. Cave drips show apparently random, non-seasonal variation in the 18O / 16O isotopic compostion but the weighted mean of the 18O/16O isotope composition of precipitation provides a good approximation to their mean 18O/16O isotopic composition. In contrast to their D/H ratios for a cave drip site in Little Trimmer Cave, Mole Creek, show a distict seasonal pattern. The 18O/16O and 13C/12C ratios have been determined for a number of actively forming speleothems. With respect to 18O/16O it is found that speleothems the three sites are being deposited under conditions approaching isotopic equilibrium. The 13C/12C ratios of these speleothems are highly variable but the generally less negative values found in Frankcombe Cave (Florentine Valley) compared with the other two sites may reflect the effects of recent clearfelling in the area.
