In southwest Victoria, like many other regions in Australia, drought, climate change and population growth have exposed gaps in water supply. To develop effective demand management strategies for rural and regional areas, this paper investigates the drivers and barriers to water saving in southwest Victoria. Although the majority of people felt water saving was important, the drivers for water saving differed between different groups. Residential users were saving water for altruistic reasons, while for farmers the drivers were farm viability and productivity. Although the barriers differed between property types, common barriers included lack of understanding of the impact their water use has on supplies, lack of knowledge, the pricing system and distrust of the water authority. The findings provide information for effective demand management strategies for the region.

The morphological variation in 104 local races of plum (Prunus domestica subsp. domestica L.) in the Nordic Gene Bank’s Prunus clone archive in Pälkäne, Southwest Finland was examined. Each tree was described using 37 characteristics. On the basis of fruit characteristics the local races were classified into three main groups. The largest one was the red plum group, the yellow plum group being the second largest. Victoria-type plums, which have not been reported to occur in Finland before and which resemble the English cultivar ‘Victoria’, make up the third group. Victoria-type plums proved to be fully and red plums partly self-compatible, whilst the yellow plums were selfincompatible. All the local races of plum were evaluated for their possible further use. Two of them were selected for commercial propagation.

The Early Cretaceous Jehol Biota from northeastern China has produced an abundance of well preserved birds, mammals and feathered dinosaurs, amongst other fossils. The similarities in the nature of the deposits producing these fossils to the lacustrine facies of the Strzelecki Group of southwest Gippsland, Victoria, Australia suggests that a prolonged, systematic search of those rocks in Australia could yield fossils of similar quality.

ABSTRACT The Drygalski Ice Tongue presents an ~80 km long floating obstacle to alongshore flows in the Victoria Land coastal ocean region of the Western Ross Sea. Here we use oceanographic data from near to the tongue to explore the interplay between the floating glacier and the local currents and stratification. A vessel-based circuit of the glacier, recording ocean temperature and salinity profiles, reveals the southwest corner to be the coldest and most complex in terms of vertical structure. The southwest corner structure beneath the surface warm, salty layer sustains a block of very cold water extending to 200 m depth. In this same location there was a distinct layer at 370 m not seen anywhere else of water at ~−1.93°C. The new observations broadly, but not directly, support the presence of a coherent Victoria Land Coastal Current. The data suggest the northward moving coastal current turns against the Coriolis force and works its way anticlockwise around the glacier, but with leakage beneath the glacier through the highly ‘rippled’ underside, resulting in a spatially heterogeneous supply to the Terra Nova Bay Polynya region – an important location for the formation of high-salinity shelf water.

THE 150th Anniversary of William Blandowski’s 1856-57 expedition to the Murray River provided the opportunity for the Royal Society of Victoria to hold a symposium to reassess the significance of Blandowski’s life and career before, during and after his time in Australia. Despite Blandowski’s significant role in the early years of the Royal Society, few of its members had heard of Blandowski and even fewer knew of his work as an artist and naturalist. This was part of the impetus behind the symposium. Another was to make information on the Murray River expedition available to residents of northwest Victoria and southwest New South Wales, the area where most of its collecting took place.

The Annieopsquotch Complex is an ophiolite that forms the Annieopsquotch Mountains of southwest Newfoundland. It contains rocks of the critical zone, gabbro zone (2.3 km thick), sheeted dyke zone (1.5 km thick), and pillow lava zone of a typical ophiolite. The zones trend northeast, face and dip southeast at approximately 50–70°, and are offset by faults.Cumulate rocks of the critical zone preserve graded layers, trough structures, and slump folds and locally are metamorphosed and deformed. The gabbro zone contains many textural varieties of gabbro, pegmatitic pods, layering, trondhjemite pods, and amphibolite near the base. It passes through a transition zone to a sheeted dyke zone that extends the full strike length of the ophiolite. Dykes trend northwest and are aphyric or plagioclase-phyric diabase. The pillow lava zone, besides pillow basalt, contains minor pillow breccia, hyaloclastite, and chert.The Annieopsquotch Complex is faulted against an Ordovician tonalite terrane to the northwest across the Lloyds River Fault and against the Victoria Lake Group to the southeast. It is cut by dykes and sills correlated with both these units. The complex is cut by two Late Ordovician gabbro–diorite intrusions and a granite of presumed Devonian age and is unconformably overlain by Early Silurian terrestrial sedimentary and volcanic rocks.Major-, trace-element, and clinopyroxene chemistry of the complex and other ophiolitic fragments between Buchans and King George IV Lake is typical of N-type MORB. These likely constituted one allochthon of Iapetus Ocean or marginal basin crust emplaced over the Ordovician continental margin of North America during the Taconic Orogeny.

The CO2CRC has a demonstration storage project underway in the Otway Basin of southwest Victoria. The aim of the project is to demonstrate that carbon capture and storage (CCS) can be performed under Australian conditions. The project involves extracting CO2 rich gas from an existing field and injecting it into a nearby depleted natural gas field for long-term storage. Injection commenced in April 2008, and approximately 100,000 tonnes of CO2 are planned to be injected through a new injection well drilled in 2007. A multi-disciplinary monitoring and verification (M&V) program has been in place from late 2005 and a baseline state of the subsurface, near surface and atmospheric conditions has been comprehensively defined prior to the commencement of injection. The project has also been instrumental in unravelling the legislative overlaps between jurisdictions and has helped shape the regulatory regime being developed by the Victorian Government. At the present time over 35,000 tonnes of CO2 has been injected and a variety of monitoring data collected. This paper aims to provide an update on the holistic project and how some of the findings may lead to expediting commercial uptake of CCS in Australia.

AbstractThe Lower Palaeozoic Bonney Pluton is a regionally extensive coarse-grained, variably megacrystic, monzodioritic to granitic body that crops out over 1000 km2 in South Victoria Land. It intruded upper amphibolite facies Koettlitz Group metasediments and interlayered orthogneisses. Magmatic fabrics are developed in the centre of the pluton by flow alignment of K-feldspars before the majority of phases had crystallized, whereas solid-state fabrics developed in the pluton margins by ductile–plastic deformation. Structures developed in the host-rocks vary around this elongate northwest–southeast-trending pluton. Upright, tight northwest–southeast-trending macroscopic folds are developed at the sides of the pluton, with axis-parallel stretching lineations and boudinage indicating strong northwest–southeast extension. Broad warps of tight macroscopic folds, and mesoscopic refolded folds, sheath folds and complicated interference patterns characterize areas at the ends of the pluton. Emplacement of the pluton involved radial expansion in a regional northeast–southwest compression, and growth predominantly in the northwest–southeast direction. Superposition of the radial expansion and regional compression resulted in an inhomogeneous strain field at a regional scale, with coaxial strain at the sides of the pluton and non-coaxial strain at the ends. Upright folds developed at the pluton's sides, and became tighter with continued coaxial deformation. Non-coaxial structures developed at the ends of the pluton and were pushed aside by the growing pluton into areas of coaxial deformation, resulting in complex folding, re-folding and sheath folds. Metamorphism of the host-rocks and migmatite development was more intense at the sides of the pluton than near the ends, possibly due to different P-T-t paths of host-rocks around syntectonic plutons.

AbstractMassive tabular icebergs (∽1000km2 surface area, ∽1011 kg mass) arrived in the southwest Ross Sea in early 2001 where they remained relatively immobile for the next 4 years. During the period of their presence, extensive landfast sea ice (fast ice) waxed and waned along the Victoria Land coast, with maximum coverage exceeding typical coverage prior to the arrival of the icebergs by a factor of 5. The purposes of this study are to determine (1) whether the extensive ‘iceberg blockade’ extending from Ross Island to Drygalski Ice Tongue was indeed, as intuition suggests, responsible for the unusual fast-ice conditions, and (2) how storm frequency, intensity and seasonal timing may have mitigated the effects of the icebergs. Our simple analysis of glaciological and atmospheric conditions observed during 2001–05 suggests that iceberg movement alone is not sufficient to explain fast-ice variability; and, in fact, it is the detailed interplay between storms and iceberg location that determine this variability.

Austral autumn 2017 was classified as neutral in terms of the El Niño–Southern Oscillation (ENSO), although tropical rainfall and sub-surface Pacific Ocean temperature anomalies were indicative of a weak La Niña. Despite this, autumn 2017 was anomalously warm formost of Australia, consistent with the warming trend that has been observed for the last several decades due to global warming. The mean temperatures for Queensland, New South Wales, Victoria, Tasmania and South Australiawere all amongst the top 10. The mean maximum temperature for all of Australia was seventh warmest on record, and amongst the top 10 for all states but Western Australia, with a region of warmest maximum temperature on record in western Queensland. The mean minimum temperature was also above average nationally, and amongst top 10 for Queensland, Victoria and Tasmania. In terms of rainfall, there were very mixed results, with wetter than average for the east coast, western Victoria and parts of Western Australia, and drier than average for western Tasmania, western Queensland, the southeastern portion of the Northern Territory and the far western portion of Western Australia. Dry conditions in Tasmania and southwest Western Australia were likely due to a positive Southern Annular Mode, and the broader west coast and central dry conditions were likely due to cooler eastern Indian Ocean sea-surface temperatures (SSTs) that limited the supply of moisture available to the atmosphere across the country. Other significant events during autumn 2017 were the coral bleaching in the Great Barrier Reef (GBR), cyclone Debbie andmuch lower than average Antarctic sea-ice extent. Coral bleaching in the GBR is usually associated on broad scales with strong El Niño events but is becoming more common in ENSO neutral years due to global warming. The southern GBR was saved from warm SST anomalies by severe tropical cyclone Debbie which caused ocean cooling in late March and flooding in Queensland and New SouthWales. The Antarctic sea-ice extent was second lowest on record for autumn, with the March extent being lowest on record.

Abstract. The chemical composition of groundwater and surface water is often considered to be dominated by water–rock interactions, particularly weathering; however, it has been increasingly realised that plant uptake can deplete groundwater and surface water of nutrient elements. Here we show, using geochemical mass balance techniques that at our study site in Southwest Victoria, Australia, water–rock interactions do not control the hydrochemistry. Instead the chemical species provided by rainfall are depleted by plant biomass uptake and exported, predominantly through fire. Regular landscape burning by Aboriginal land users is hypothesized to have caused the depletion of chemical species in groundwater for at least the past 20 000 yr by accelerating the export of elements that would otherwise have been stored within the local biomass. These findings are likely to be representative of southeast Australia, as well as similar climatic regions elsewhere in the globe, and contrast with Northern Hemisphere studies of groundwater and surface water chemistry, where water–rock interactions are the dominant hydrochemical control.

Geological sequestration is a promising technology for reducing atmospheric emissions of carbon dioxide (CO2) with the potential to geologically store a significant proportion Australia of Australia’s stationary CO2 emissions. Stationary emissions comprise almost 50% (or about 280 million tonnes of CO2 per annum) of Australia’s total greenhouse gas emissions. Australia has abundant coal and gas resources and extensive geological storage opportunities; it is therefore well positioned to include geosequestration as an important part of its portfolio of greenhouse gas emission mitigation technologies.The Cooperative Research Centre for Greenhouse Gas Technologies is undertaking a geosequestration demonstration project in the Otway Basin of southwest Victoria, with injection of CO2 planned to commence around mid 2007. The project will extract natural gas containing a high percentage of CO2 from an existing gas well and inject it into a nearby depleted natural gas field for long-term storage. The suitability of the storage site has been assessed through a comprehensive risk assessment process. About 100,000 tonnes of CO2 is expected to be injected through a new injection well during a one- to two-year period. The injection of CO2 will be accompanied by a comprehensive monitoring and verification program to understand the behaviour of the CO2 in the subsurface and determine if the injected carbon dioxide has migrated out of the storage reservoir into overlying formations. This project will be the first storage project in Australia and the first in the world to test monitoring for storage in a depleted gas reservoir. Baseline data pertinent to geosequestration is already being acquired through the project and the research will enable a better understanding of long-term reactive transport and trapping mechanisms.This project is being authorised under the Petroleum Act 1998 (Victoria) and research, development and demonstration provisions administered by the Environment Protection Authority (EPA) Victoria in the absence of geosequestration- specific legislation. This highlights the need for such legislation to enable commercial-scale projects to proceed. Community acceptance is a key objective for the project and a consultation plan based on social research has been put in place to gauge public understanding and build support for the technology as a viable mitigation mechanism.

Abstract. The chemical composition of groundwater and surface water is often considered to be dominated by water–rock interactions, particularly weathering; however, it has been increasingly realised that plant uptake can deplete groundwater and surface water of nutrient elements. Here we show, using geochemical mass balance techniques, that water–rock interactions do not control the hydrochemistry at our study site within a granite terrain in southwest Victoria, Australia. Instead the chemical species provided by rainfall are depleted by plant biomass uptake and exported, predominantly through fire. Regular landscape burning by Aboriginal land users is hypothesized to have caused the depletion of chemical species in groundwater for at least the past 20 000 yr by accelerating the export of elements that would otherwise have been stored within the local biomass. These findings are likely to be applicable to silicate terrains throughout southeast Australia, as well as similar lithological and climatic regions elsewhere in the globe, and contrast with studies of groundwater and surface water chemistry in higher rainfall areas of the Northern Hemisphere, where water–rock interactions are the dominant hydrochemical control.

Abstract. A typhoon struck the Pearl River Estuary in September 1874 (“Typhoon 1874”), causing extensive damage and claiming thousands of lives in the region during its passage. Like many other historical typhoons, the deadliest impact of the typhoon was its associated storm surge. In this paper, a possible track of the typhoon was reconstructed through an analysis of the historical qualitative and quantitative weather observations in the Philippines, the northern part of the South China Sea, Hong Kong, Macao, and Guangdong recorded in various historical documents. The magnitudes of the associated storm surges and storm tides in Hong Kong and Macao were also quantitatively estimated using storm surge model and analogue astronomical tides based on the reconstructed track. The results indicated that the typhoon could have crossed the Luzon Strait from the western North Pacific and moved across the northeastern part of the South China Sea to strike the Pearl River Estuary more or less as a super typhoon in the early morning on 23 September 1874. The typhoon passed about 60 km south–southwest of Hong Kong and made landfall in Macao, bringing maximum storm tides of around 4.9 m above the Hong Kong Chart Datum (http://www.geodetic.gov.hk/smo/gsi/Data/pdf/explanatorynotes.pdf, last access: 3 January 2020) at the Victoria Harbour in Hong Kong and around 5.4 m above the Macao Chart Datum (https://mosref.dscc.gov.mo/Help/ref/Macaucoord_2009_web_EN_v201702.pdf, last access: 3 January 2020) at Porto Interior (inner harbour) in Macao. Both the maximum storm tide (4.88 m above the Hong Kong Chart Datum) and maximum storm surge (2.83 m) brought by Typhoon 1874 at the Victoria Harbour estimated in this study are higher than all the existing records since the establishment of the Hong Kong Observatory in 1883, including the recent records set by super typhoon Mangkhut on 16 September 2018.

Interactions between Australian fur seals (Arctocephalus pusillus doriferus) and the Southern Squid Jig Fishery (SSJF) were investigated in April–May 2002. Details on the number of seals present, distance from the vessel, age and gender, and their behaviour were recorded using scan sampling techniques over 26 nights from eight vessels operating out of Portland and Port Fairy on the southwest coast of Victoria. Seals were observed on all nights but none were recorded in 30% of all (777) scan observations. Of the seals attending vessels at any one time (1.89 ± 0.24), 67% were involved in activities unrelated to jigging operations with the most common behaviour category being resting/grooming. Only 3.6% of observations involved seals targeting squid caught on jig lures whereas a further 29% were of foraging on squid within 40 m of the vessel. Damage to fishing gear attributable to seals was recorded on only three occasions. There was no evidence of negative impacts on seals from vessel operations. The majority of seals foraging on squid around vessels were adult females (71%) with the remainder being almost exclusively juvenile males. The current level of interactions between Australian fur seals and vessels in the SSJF appears minor.

On all of 120 farms in south-west Victoria that were selected at random and sampled during autumn and winter over 2 years, perennial ryegrass was present in the pasture and tested positive for the presence of the naturally occurring ryegrass endophyte, Neotyphodium lolii (mean frequency 78%). Ryegrass staggers were reported on 33% (1999) and 43% (2000) of the surveyed farms. Clinically significant concentrations of lolitrem B were detected in perennial ryegrass samples with concentrations in the range 0–4.44 mg/kg. Concentration exceeded 1.8 mg/kg in 37% of pastures indicating an inherent, widespread problem for livestock farmers. Concentration was independent of endophyte frequency, pasture age, pasture height, annual rainfall and origin of sown cultivar. Ergovaline was detected in most of the perennial ryegrass samples with concentrations up to 3.90 mg/kg. In 1999, the mean concentration of ergovaline was 0.76 (± 0.70) mg/kg with 33% of pastures having a level >0.4 mg/kg, the level associated with heat stress in cattle. In 2000, sampling was carried out later in the year than for the 1999 survey and the mean concentration of ergovaline was 0.12 (± 0.10) mg/kg; 3% of samples exceeded 0.4 mg/kg. The mean concentration of peramine was 13.7 (± 6.6) mg/kg in the 1999 survey and 4.2 (± 5.1) mg/kg in the 2000 survey. Mineral analysis indicated that perennial ryegrass nutrition was inadequate with regard to phosphorous on 17% of the dairy pastures and on 37% of the sheep/beef pastures. Potassium was deficient in perennial ryegrass on 5 and 37% of dairy and sheep/beef pastures respectively. For perennial ryegrass in sheep/beef pastures, 25% were deficient in sulphur. For lactating cattle having only perennial ryegrass as a food source, phosphorous and copper concentrations in the grass were inadequate on 80% of the pastures. Calcium, zinc, magnesium, potassium and sulphur concentrations in perennial ryegrass were also inadequate on some pastures. However, with 1 exception, the ratio [K/(Ca+Mg) expressed as equivalents] was less than 2.2, the level associated with the development of hypomagnesemia. Hypomagnesemia (grass tetany) was therefore unlikely to be a major cause of the staggers syndrome. Lolitrem B was negatively correlated with grass potassium concentration (P<0.001). Ergovaline was negatively correlated with date of sampling (P<0.001). Peramine concentration was positively correlated with endophyte frequency, the potassium and sodium concentrations in perennial ryegrass and negatively correlated with date of sampling. The need for research on the economic impact and management of pasture contaminated with ryegrass endophyte toxins is discussed.

In recent years, many droughts have happened over mainland Australia, especially the two severe prolonged droughts, from 2006 to 2009 and 2018 to 2020, resulting in serious water scarcity. Therefore, using the Total Storage Deficit Index (TSDI) from the Gravity Recovery and Climate Experiment (GRACE), we analyzed the two severe prolonged droughts from the perspective of the affected area, spatial evolution, frequency, severity and drought driving factors. The results show that the affected area of Drought 2006–2009 ranged from 57% to 95%, and that of Drought 2018–2020 ranged from 45% to 95%. Drought 2006–2009 took its rise in southeastern Australia and gradually spread to the central part. Drought 2018–2020 originated in the southwest corner of the Northern Territory and northern New South Wales, and gradually expanded to Western Australia and the whole New South Wales respectively. During Drought 2006–2009, Victoria suffered drought all months, including 59% mild drought and 41% moderate drought, North Territory had the highest drought severity of 44.26 and Victoria ranked the second high with the severity of 35.51 (cm months). For Drought 2018–2020, Northern Territory was also dominated by drought all months, including 92% mild drought and 8% moderate drought, the drought severities were in North Territory and Western Australia with 52.19 and 31.44 (cm months), respectively. Finally, the correlation coefficients between the two droughts and Indo-Pacific climate variability including El Niño-Southern Oscillation and Indian Ocean Dipole (IOD) are computed. By comparing the correlation coefficients of Drought 2018–2020 with Drought 2006–2009, we find that the impact of the El Niño on the hydrological drought becomes weaker while IOD is stronger, and the role of Southern Oscillation on droughts is diverse with the quite different spatial patterns. The results from Fourier analysis confirm that the two hydrological droughts are all related to Indo-Pacific climate variability but with slightly different driving mechanisms.

AbstractThe lithobiomorph centipede Henicops is widely distributed in Australia and New Zealand, with five described species, as well as two species in New Caledonia and Lord Howe Island. Parsimony, maximum likelihood and Bayesian analyses of ca. 800 aligned bases of sequence data from 16S rRNA and 28S rRNA were conducted on a dataset including multiple individuals of Henicops species from populations sampled from different parts of species' geographic ranges, together with the allied henicopines Lamyctes and Easonobius. Morphological characters are included in parsimony analyses. Molecular and combined datasets unite species from eastern Australia and New Zealand to the exclusion of species from Western Australia, New Caledonia and Lord Howe Island. The molecular data favour these two geographic groupings as clades, whereas inclusion of morphology resolves New Caledonia, Lord Howe Island, southwest Western Australia and Queensland as successive sisters to southeastern Australia and New Zealand. The basal position of the Lord Howe Island species in the phylogeny favours a diversification of Australasian Henicops since the late Miocene unless the Lord Howe species originated in a biota that pre-dates the island. The molecular and combined data resolve the widespread morphospecies H. maculatus as paraphyletic, with its populations contributing to the geographic groupings New South Wales + New Zealand and Tasmania + Victoria.

We studied populations of frogs of the genus Atelopus from the Pasto Massif of the Andes in southern Colombia and northern Ecuador, and from the Huancabamba depression in southern Ecuador and northern Perú and conclude that they belong to six species, five of which are described as new to science. Atelopus angelito is recorded for the first time from Ecuador and its range is extended 183 km (airline) southwest of its type locality in Departamento del Cauca, Colombia. We distinguish the five new species from similar ones using features of coloration, skin texture, and morphometrics. We also include osteological data for four of the new species. A putative hybrid zone at Provincia Imbabura, Ecuador, is proposed to exist between the non-sister taxa A. ignescens and one of the new species. Because recent records of four of the new species and A. angelito are lacking despite search efforts, we hypothesize that they are possibly extinct, as are many other Andean Atelopus. Thus, we categorize these species, applying IUCN Red List criteria, as Critically Endangered (Possibly Extinct). No search efforts have been carried out for one new species (from La Victoria, Colombia); thus, it is included under the Data Deficient category. The conservation of Atelopus is briefly discussed.

Abstract. Detailed, stratigraphically well-constrained environmental reconstructions are available for Paleocene and Eocene strata at a range of sites in the southwest Pacific Ocean (New Zealand and East Tasman Plateau; ETP) and Integrated Ocean Discovery Program (IODP) Site U1356 in the south of the Australo-Antarctic Gulf (AAG). These reconstructions have revealed a large discrepancy between temperature proxy data and climate models in this region, suggesting a crucial error in model, proxy data or both. To resolve the origin of this discrepancy, detailed reconstructions are needed from both sides of the Tasmanian Gateway. Paleocene–Eocene sedimentary archives from the west of the Tasmanian Gateway have unfortunately remained scarce (only IODP Site U1356), and no well-dated successions are available for the northern sector of the AAG. Here we present new stratigraphic data for upper Paleocene and lower Eocene strata from the Otway Basin, southeast Australia, on the (north)west side of the Tasmanian Gateway. We analyzed sediments recovered from exploration drilling (Latrobe-1 drill core) and outcrop sampling (Point Margaret) and performed high-resolution carbon isotope geochemistry of bulk organic matter and dinoflagellate cyst (dinocyst) and pollen biostratigraphy on sediments from the regional lithostratigraphic units, including the Pebble Point Formation, Pember Mudstone and Dilwyn Formation. Pollen and dinocyst assemblages are assigned to previously established Australian pollen and dinocyst zonations and tied to available zonations for the SW Pacific. Based on our dinocyst stratigraphy and previously published planktic foraminifer biostratigraphy, the Pebble Point Formation at Point Margaret is dated to the latest Paleocene. The globally synchronous negative carbon isotope excursion that marks the Paleocene–Eocene boundary is identified within the top part of the Pember Mudstone in the Latrobe-1 borehole and at Point Margaret. However, the high abundances of the dinocyst Apectodinium prior to this negative carbon isotope excursion prohibit a direct correlation of this regional bio-event with the quasi-global Apectodinium acme at the Paleocene–Eocene Thermal Maximum (PETM; 56 Ma). Therefore, the first occurrence of the pollen species Spinizonocolpites prominatus and the dinocyst species Florentinia reichartii are here designated as regional markers for the PETM. In the Latrobe-1 drill core, dinocyst biostratigraphy further indicates that the early Eocene (∼ 56–51 Ma) sediments are truncated by a ∼ 10 Myr long hiatus overlain by middle Eocene (∼ 40 Ma) strata. These sedimentary archives from southeast Australia may prove key in resolving the model–data discrepancy in this region, and the new stratigraphic data presented here allow for detailed comparisons between paleoclimate records on both sides of the Tasmanian Gateway.

Detailed mapping based on the high-resolution grids, such as GEBCO, ETOPO1, GlobSed, EGM-2008 is crucial for various domains of Earth sciences: geophysics, glaciology, Quaternary, sedimentology, geology, environmental science, geomorphology, etc. The study presented a GMT-based scripting techniques of the cartographic data processing aimed at the comparative analysis of the bathymetry, sediment thickness, geologic objects and geophysical settings in the study area based on various datasets. The study area is located in the Ross Sea, Antarctic. The highest values of the sediment thickness over 7,500 m are dominating in the southwest segment of the Ross Sea closer to the Victoria Land, followed by the region over the Ross Ice Shelf with values between 5,500 to 7,000 m (170°-175°W). The increased sediment thickness (2,500 to 3,000 m) was also mapped seen in the region NE off the Sulzberger Bay (70-75°S to 140-155°W), caused by the closeness of the Marie Bird Land ice coasts. A remarkable correlation between the gravity and the topography of the sea-land border in the Marie Bird Land area is well reflected in the coastal line and a set of the higher values in the free-air gravity. On the contrary, negative values (–60 to -80 mGal) are notable along the submarine toughs stretching parallel in the western part of the basin: e.g. the trough stretching in NW-SE direction in the 170°W-175°E, 65°S-68°S, between the 167°W-175°W, 70°S-72°S. Such correlations are clearly visible on the map, indicating geological lineaments and bathymetric depressions correlating with gravity grids. The paper contributes to the regional studies of the Ross Sea, the Antarctic and Polar region, and development of the cartographic technical methodologies by presenting an application of the GMT for thematic mapping.

AbstractWe present new interpretations of deglaciation in McMurdo Sound and the western Ross Sea, with observationally based reconstructions of interactions between East and West Antarctic ice at the last glacial maximum (LGM), 16000, 12000, 8000 and 4000 BP. At the LGM, East Antarctic ice from Mulock Glacier split; one branch turned westward south of Ross Island but the other branch rounded Ross Island before flowing southwest into McMurdo Sound. This flow regime, constrained by an ice saddle north of Ross Island, is consistent with the reconstruction of Stuiver and others (1981a). After the LGM, grounding-line retreat was most rapid in areas with greatest water depth, especially along the Victoria Land coast. By 12000 BP, the ice-now regime in McMurdo Sound changed to through-flowing Mulock Glacier ice, with lesser contributions from Koettlitz, Blue and Ferrar Glaciers, because the former ice saddle north of Ross Island was replaced by a dome. The modern flew regime was established ∼4000 BP. Ice derived from high elevations on the Polar Plateau but now stranded on the McMurdo Ice Shelf, and the pattern of the Transantarctic Mountains erratics support our reconstructions of Mulock Glacier ice rounding Minna Bluff but with all ice from Skelton Glacier ablating south of the bluff. They are inconsistent with Drewry’s (1979) LGM reconstruction that includes Skelton Glacier ice in the McMurdo-Sound through-flow. Drewry’s (1979) model closely approximates our results for 12000-4000 BP. Ice-sheet modeling holds promise for determining whether deglaciation proceeded by grounding-line retreat of an ice sheet that was largely stagnant, because it never approached equilibrium flowline profiles after the Ross Ice Shelf grounded, or of a dynamic ice sheet with flowline profiles kept low by active ice streams that extended northward from present-day outlet glaciers after the Ross Ice Shelf grounded.

Tanzania is one of the leading gold mining countries in the world and the discovery of new gold resources on its territory is an actual task. Known gold deposits are concentrated mainly in the northwest of the country, in the metallogenic zone of Lake Victoria, where they are associated with the Archean greenstone belts, and to a lesser extent – in the southwest, in the ore regions of Lupa and Mpanda, confined to the Ubendian Paleoproterozoic mobile belt. With regard to the eastern regions of Tanzania, where the Proterozoic structures of the Uzagaran mobile belt are developed, until recently in this region any significant manifestations of gold mineralization were not known. As a result of our research in the northern part of the Morogoro province of the Republic of Tanzania, a new previously unknown gold deposit Mananila was discovered. It is represented by a large volume, up to 400–450 m long, up to 60–80 m thick, mineralized shear zone over intensely leached and schistosed migmatites, gneisses, amphibolites, penetrated by echelon systems of quartz veins and veinlet, steeply dipping bodies of quartz breccia up to 1.0–1.5 m thick. Gold contents range from 0.61 to 8.11 g/t, the average zone content is 2.5–3.0 g/t. Parallel to the main zone, similar structures are developed on the site, although they are of lower thickness. The forecast resources of the deposit are estimated at 20 tons of gold. 2.8 km to the east from the Mananila field, the recently discovered Mazizi gold deposit is located, and a number of small occurrences of gold are also known in the region. All these objects are located within a large shear zone of the northeastern strike, up to 4–5 km width, over 20 km in length. This serves as the basis for the identification of a new gold ore region in the northern part of the Morogoro province of the United Republic of Tanzania, within the Proterozoic mobile belt of Usagaran, the possible gold content of which has never been previously discussed in geological literature.

Woodside has been managing seismic acquisition and drilling operations as part of a gas exploration program in the offshore Otway Basin in southwest Victoria since July 1999. There are a number of sensitive and complex environmental and multiple-use issues facing companies undertaking exploration activities in these waters, including a seasonal aggregation of feeding blue whales, winter calving and breeding habitat for southern right whales and a productive rock lobster fishery. Recent changes to the legislative regime for environmental approvals of petroleum activities in Commonwealth waters has introduced further complications for operators in this area. Consequently, a key aspect of this exploration program has been the pro-active management of environmental and stakeholder issues.A comprehensive management strategy addressing these issues was developed for seismic acquisition and drilling operations, with the key objectives of ensuring regulatory compliance and facilitating a process where all stakeholders were fully informed about proposed activities. This process focussed on informing stakeholders of the potential impacts of seismic acquisition and drilling, and how Woodside intended to manage those impacts. This approach was driven by a desire for continuous improvement of performance, over and above compliance with all regulatory requirements. It also recognises the legitimacy of stakeholder risk through social, environmental and political values, and has had environmental and economic benefits for the project.Environmental benefits included early identification and assessment of potential environmental impacts resulting from the different phases of exploration, development of management strategies to control and mitigate these potential impacts, and improved environmental awareness across the project team, joint venture partners and external stakeholders. Prevention of delay or denial of regulatory approvals for exploration activities had significant economic benefits to Woodside and the joint venture partners. The development and implementation of a stakeholder involvement process, involving explorers, external affairs and environmental advisers, was an innovative approach that has application across other Woodside activities and the industry generally, particularly for projects in locations with a high level of environmental sensitivity, multiple-use and stakeholder concern.

Record-high oil prices along with on-going development of infrastructure, increasing domestic demand and international LNG sales continued to drive significant investment in exploration in onshore and offshore Australia during 2007. These trends are reflected nationally by strong uptake of acreage and continued high levels of drilling activity and seismic acquisition. Overall, drilling and discovery trends were similar to 2006 which showed significant exploration activity focussed on proven hydrocarbon basins (Carnarvon, Browse, Perth and Cooper basins). Most petroleum discoveries made in 2007 were located within 10 to 15 km of existing fields. In terms of number of exploration wells, the offshore Carnarvon continued to dominate with over 20 new field wildcats drilled. Discoveries include a major deep-water gas find for BHP-Billiton at Thebe-1 on the outer Exmouth Plateau, Apache’s gas finds at Brunello–1, Julimar–1 and Julimar East–1, oil for Santos at Fletcher–1 and gas at Lady Nora–1 for Woodside. The Browse Basin saw a significant increase in drilling activity with some success. Exploration in the offshore southwest margin received a major boost with a series of shallow-water discoveries for ROC Oil in the Perth Basin with gas at Frankland–1 395and Perseverance–1 and gas and oil at Dunsborough–1. Onshore, the Cooper/Eromanga basins continued to experience the highest level of drilling activity and seismic acquisition. This activity resulted in numerous small to moderate oil discoveries for Santos, Beach Petroleum, Eagle Bay Resources, Stuart Petroleum and Victoria Petroleum. There were a few notable exceptions to near-field exploration in 2007 with several wildcats drilled in frontier regions including PetroHunter Energy and Sweetpea Petroleum’s Shanendoah–1 in the Georgina/Betaloo basins, Austin’s Gravestock–1 in the onshore Stansbury Basin and the onshore drilling campaign by ARC Energy in the Canning Basin. In Queensland, CSM exploration and discovery continued to experience strong positive growth underpinned by delivery to local markets.

Satellite based rainfall estimation techniques have emerged as a potential alternative to ground based rainfall measurements. The Tropical Rainfall Measuring Mission (TRMM) precipitation, in particular, has been used in various climate and hydrology based studies around the world. While having wide possibilities, TRMM rainfall estimates are found to be inconsistent with the ground based rainfall measurements at various locations such as the southwest coast and Himalayan region of India, northeast parts of USA, Lake Victoria in Africa, La Plata basin in South America, etc. In this study, the applicability of TRMM estimates is evaluated over the Upper Ganga Basin (Himalayan catchment) by comparing against gauge-based India Meteorological Department (IMD) gridded precipitation records. Apart from temporal evaluation, the ability of TRMM in capturing spatial distribution is also examined using three statistical parameters namely correlation coefficient (r), mean absolute error (MAE) and relative bias (RBIAS). In the results, the dual nature of bias is evident in TRMM precipitation with rainfall magnitude falling in the range from 100 to 370 mm representing positive bias, whereas, rainfall magnitude above 400 mm, approximately, representing negative bias. The Quantile Mapping (QM) approach has been used to correct the TRMM dataset from these biases. The raw TRMM precipitation is found to be fairly correlated with IMD rainfall for post-monsoon and winter season with R2 values of 0.65 and 0.57, respectively. The R2 value of 0.41 is obtained for the monsoon season, whereas least correlation is found for the pre-monsoon season with an R2 value of 0.24. Moreover, spatial distribution of rainfall during post-monsoon and winter season is captured adequately; however, the limited efficiency of TRMM is reflected for pre-monsoon and monsoon season. Bias correction has satisfactorily enhanced the spatial distribution of rainfall obtained from TRMM for almost all the seasons except for monsoon. Overall, the corrected TRMM precipitation dataset can be used for various climate analyses and hydrological water balance based studies in the Himalayan river basins.

The 2004-2005 influenza season in Europe started in late December 2004 and the first influenza activity occurred in the west and southwest (Spain, United Kingdom and Ireland). Influenza activity then moved gradually east across Europe during January and early February 2005, and from late February until late March, most movement was south to north. The intensity of clinical influenza activity in ten out of 23 countries was higher than during the 2003-2004 season, and lower or equal to the 2003-2004 season in the other 13 countries. The highest consultation rates were generally observed among children aged 0-14 years. However, the peak consultation rates due to influenza-like illness or acute respiratory infection were not especially high when compared with historical data. The predominant virus strain was influenza A (83% of total detections) of the H3 subtype (85% of H-subtyped A viruses), with fewer influenza B (17% of total detections) or A(H1) viruses (15 % of H-subtyped A viruses) detected. The vast majority of A(H3) viruses were similar to the reference strains A/Wellington/1/2004 (H3N2) and, subsequently, A/California/7/2004 (H3N2) that are closely related drift variants of the A/Fujian/411/2002 (H3N2) prototype vaccine strain. The B viruses co-circulated with A viruses during the whole influenza season in 11 out of 24 countries. Seven of these were located in the northeast of Europe and in these countries the proportion of B viruses was higher (range: 31-60%) than in the rest of Europe (range: 6-26%). In 13 out of 24 countries the B viruses circulated relatively late in the season. About 43% of all antigenically characterised B viruses were B/Hong Kong/330/2001-like (B/Victoria/2/87 lineage), a strain that is distinguishable from the vaccine influenza B strain, which was a B/Yamagata/16/88 lineage virus. Based on the viruses detected worldwide until February 2005, the World Health Organization modified the composition of the 2005-2006 influenza vaccine from the 2004-2005 season vaccine to include a new A(H3N2) component: an A/California/7/2004 (H3N2)-like virus.

The southwest coast of Western Australia is heavily influenced by the south-flowing Leeuwin Current. In summer, the current shifts and the north-flowing Capes Current delivers water from the south to nearshore environments and with it a supply of larvae from cooler waters. The nudibranch Tenellia catachroma (Burn, 1963) was considered restricted to Victorian waters; however, its discovery in eastern South Australia in 2013 revealed its capacity to expand its range west. In March 2017 a single individual was observed in shallow subtidal waters at Cape Peron, Western Australia, some 2000 km to the west of its previous range limit. Moreover, its distribution has extended northwards, possibly aided by the Capes Current, into a location of warming. This observation significantly increases the range for this Victorian emigrant to encompass most of the southern Australian coast, and also represents an equatorward shift at a time when the reverse is expected.

Pelargonium capitatum (rose pelargonium) is a plant indigenous to southern Africa, originally brought to Western Australia for its ornamental qualities. It has since become naturalized in the Southwest Australian Floristic Region, recognized for its high level of species endemism, where it is a serious invasive weed in bushlands and coastal dunes. Since P. capitatum outcompetes native species it is listed among the top 10 most important coastal weeds of the region (3). In 2008, large patches of stunted, dying, and dead P. capitatum plants were observed within a population covering coastal dunes at Woodman Point, Western Australia (GPS coordinates 32°07′40.51″S, 115°45′28.39″E). Diseased plants had small misshapen leaves in clumps that were often chlorotic or pink, shortened internodes, and exhibited phylloidy typical of infection by a phytoplasma. From August 2009 to January 2010, samples from symptomatic and asymptomatic plants were collected from the site and from plants of an asymptomatic population at another site located on the Murdoch University campus nearby. DNA was extracted from 15 samples collected from symptomatic and asymptomatic plants at the dune site and from five at the campus site. Briefly, 2 to 5 g of leaf and stem tissue was cut into 5-mm pieces and shaken overnight in 30 ml of phosphate-buffered saline buffer. Supernatant was filtered and a pellet was collected by centrifugation. After resuspension in 500 μl of extraction buffer (200 mM Tris-HCl [pH 7.5] 250mM NaCl, 25mM ethylenediaminetetraacetic acid, 0.5% sodium dodecyl sulfate, and 2% polyvinylpyrrolidone), DNA was precipitated in 500 μl of cold isopropanol. Samples were tested for the presence of phytoplasma ribosomal 16S DNA by nested PCR using phytoplasma universal primers P1/P7 followed by amplification with primers Tint, R16mF2, and R16mR1 (1,2,4). Phytoplasma-specific DNA sequences were synthesized directly from amplicons using the above primers. Phytoplasma was detected from both symptomatic and asymptomatic plant samples collected from the dune site but not from the campus site. Analysis of the nine sequences obtained (GenBank Accession Nos. HM583339, HM583340, HM583341, HM583342, HM583343, HM583344, HM583345, HM583346, and HM583347) revealed high sequence identity between isolates (~99%) and with the ‘Candidatus Phytoplasma aurantifolia’ (16SrII) group of phytoplasmas (1,4). Presence of phytoplasma in symptomatic plants was confirmed by histological examination of stem sections stained with Dienes' stain. This finding is significant because there is potential for utilizing this phytoplasma to control P. capitatum where it has invaded ecologically significant sites, although its effect on indigenous plants must be determined first. Although phytoplasmas within the 16SrII group have been identified in Australia previously (1,4), to our knowledge, this is the first report of it infecting P. capitatum. References: (1) K. S.

The story of the Great Southwest strike, a textbook example of the upheavals of 1886, has long been told as an epic battle between railway millionaire Jay Gould, national Knights of Labor head Terence Powderly, and Martin Irons, with many historians and contemporaries casting strike leader Irons as the epitome of impatient, romantic, and even deluded labor activism. District Assembly 101's call to walk out on Gould's southwestern system of roads was, arguably, strategically ill-advised. It vastly overestimated the Knights' power in the wake of two victories against Gould in 1885 and certainly ignored the district's lack of funds, lax support among skilled trainmen, and the terms of an historic agreement between the national Knights and Gould. A closer look at Irons's life and leadership, however, reveals a more complicated explanation of the strike and takes into fuller account the experiences and perceptions of striking railroaders. This essay holds that events on the ground, combined with the heady context of the Great Upheaval, influenced Irons and his supporters' decisions to strike, to expand the effort, and to defend it with violence. The ensuing attacks on Irons stemmed partly from his unstable personal history but largely from the broader social anxieties that the conflict had exposed.

Translated western hymns have a bad reputation in missiology. The term “translated” seems to convey a less than authentic expression of Christian faith. However, that was not how it happened when the Lisu of southwest China were evangelized by missionaries from the China Inland Mission in the 1920s and 1930s. The Lisu people exerted much more agency over their translated western hymns than the term “translated” implies. While the kernel of melody and message remained intact, four-part harmonies replaced unison singing. A cappella replaced piano or organ accompaniment. Phrases meaningful in a Victorian context were transformed into phrases meaningful in a Lisu mountain context. Abstract theological terms were replaced by concrete phrases. Western rhyming schemes were laid aside and Lisu poetic couplets were used instead. The end result is that in the everyday arena, in the practical living out of what it means to be a Christian for a communal and still largely oral-preference people such as the Lisu, the Lisu Christian hymns are the centerpiece of worship and devotion, of prayer and penitence. In other words, in the process of cross-cultural transmission, the Lisu hymns were not so much translated, as they were transformed.

<div align="center"><p>The Western Anachronism: thanks to western novels and Hollywood, the general public and a great many foreign visitors believe that the “Real West” is, or should be, the mythic West of cowboys and Indians, pickax miners, mountain trappers, and Oregon Trail pioneers. And for a great many busted resource towns, Real West tourism seems to be the boom waiting to replace moribund mining, logging, ranching, and agriculture. So, in many places, towns have rushed to re-create the past in order to attract visitors and new residents. Tourists want to see 19th century saloons and bordellos, old-style signs, Main Street gunfights, blacksmith shops, and hitching posts, not irrigated agriculture, sprawling suburbs, interstate highways, franchise America, and retirement communities. To meet these expectations, towns have reinvented themselves as “museums” of the Old West. For some, historic preservation and resurrection of past landscapes have sufficed, but for others, the “old” look is completely contrived. In both cases, this “Old West” iconography has become emblematic of the rapidly growing modern “New West.” It appears as Victorian, Bavarian, Mining, Wild West, Alpine, Old West, Southwest, Frontier, and other themes. Indeed, one can hardly visit a rural western town without seeing half-timbers or false fronts or board sidewalks or adobe bricks or tile roofs or some other representative adornment or period bric-a-brac. Furthermore, the activities of tourism and outdoor recreation seem most at home when rooted in these “themed” landscapes. The only problem is this: while many theme towns have enjoyed sustained economic success, the costs and tradeoffs have often rendered them no more real or stable than a western movie-set façade.</p></div>

Abstract Background Measuring health inequality is essential to ensure that everyone has equal accessibility to health care. Studies in the past have continuously presented and showed areas or groups of people affected by various inequality in accessing the health resources and services to help improve this matter. Alongside, disease prevention is as important to minimise the disease burden and improve health and quality of life. These aspects are interlinked and greatly contributes to one’s health. Method In this study, the Gini coefficient and Lorenz curve are used to give an indication of the overall health inequality. The impact of this inequality in granular level is demonstrated using Bayesian estimation for disease detection. The Bayesian estimation used a two-component modelling approach that separates the case detection process and incidence rate using a mixed Poisson distribution while capturing underlying spatio-temporal characteristics. Bayesian model averaging is used in conjunction with the two-component modelling approach to improve the accuracy of estimates by incorporating many candidate models into the analysis instead of using fixed component models. This method is applied to an infectious disease, influenza, in Victoria, Australia between 2013 and 2016 and the corresponding primary health care of the state. Result There is a relatively equal distribution of health resources and services pertaining to general practitioners (GP) and GP clinics in Victoria, Australia. Roughly 80 percent of the population shares 70 percent of the number of GPs and GP clinics. The Bayesian estimation with model averaging revealed that access difficulty to health services impacts both case detection probability and incidence rate. Minimal differences are recorded in the observed and estimated incidence of influenza cases considering social deprivation factors. In most years, areas in Victoria’s southwest and eastern parts have potential under-reported cases consistent with their relatively lower number of GP or GP clinics. Conclusion The Bayesian model estimated a slight discrepancy between the estimated incidence and the observed cases of influenza in Victoria, Australia in 2013-2016 period. This is consistent with the relatively equal health resources and services in the state. This finding is beneficial in determining areas with potential under-reported cases and under-served health care. The proposed approach in this study provides insight into the impact of health inequality in disease detection without requiring costly and time-extensive surveys and relying mainly on the data at hand. Furthermore, the application of Bayesian model averaging provided a flexible modelling framework that allows covariates to move between case detection and incidence models.

Two experiments determined the potential of N fertiliser to maximise the conversion of summer (October to April) irrigation water to pasture dry matter (DM) in southwest Victoria, Australia. DM consumed increased with increasing N (0 to 100 kg N/ha per grazing, and 50 to 200 kg N/ha every second grazing). Applications of 75 to 100 kg N/ha every grazing, and 150 to 200 kg N/ha every second grazing resulted in the highest water use efficiencies (improvements of 25 to 70% in Year 1, 40 to 63% in Year 2). Applications of 25 kg N/ha every grazing and 50 kg N/ha every second grazing led to the highest N response efficiencies (10 to 19 kg DM/kg N). The increases in DM consumed in response to N fertiliser were similar to responses noted for N applied during autumn, winter and spring in similar environments to the current experiments.

Background: Although many studies have identified the key factors influencing travel mode, they have typically centred around survey data, which has several limitations. In this research, actual transport data (GPS) has been provided by Google Environment Insights Explorer (EIE) for 169 municipalities in Australia across 2018 and 2019. Objective: A key outcome of this paper is to project the independent impact of new public transport networks (rail, bus and tram) on mode shift away from vehicles for each municipality and estimate the total distance travelled. Methods: This study uses a combination of linear regression and logit transformations to predict the proportion of automobile transport relative to all other transport modes. Results: The results suggest that South Australia would benefit from a metropolitan northeast rail line, New South Wales would benefit from a metropolitan southwest tram line, and Victoria would benefit from a metropolitan southeast bus service. Conclusion: Although the analysis is somewhat crude, it utilises open-access data and thus could be easily replicated for any country globally, which could be greatly beneficial, especially for countries with low socio-demographic backgrounds.

Bob Parker explains, in his first paragraph below, that George O. May was a major figure in US accounting. However, this paper was published in a location (Parker 2012) unlikely to be noticed by many accounting historians, let alone American ones. It was the idea of Steve Zeff (whose paper on the leaders of the US profession is referred to below) to ask if Accounting History would reprint it. I am grateful to the editors for doing so. The kind permission of the Devon History Society is acknowledged. The paper was written for Devonians rather than for accountants (though, of course, May and Parker were both born into or achieved these distinctions). For the avoidance of doubt, although there are newish places called Devon in the United States, we are referring here to the county in the southwest of old England. As usual, Bob’s writing provides a master class in clarity and efficiency. Typically, he does not make claims about theory, but we find by the end that he has developed one: seven pre-conditions for great success as an accountant in the late Victorian age. An obituary of Bob Parker was published in this journal in 2016 (Nobes 2016). C Nobes, Royal Holloway, University of London, England

IntroductionThe debate about the responsibility of museums to respect Indigenous peoples’ rights (Kelly and Gordon; Butts) has caught our attention on the basis of our previous research experience with regard to the protection of the tangible and intangible heritage of the San (former hunter gatherers) in Southern Africa (Martin and Vermeylen; Vermeylen, Contextualising; Vermeylen, Life Force; Vermeylen et al.; Vermeylen, Land Rights). This paper contributes to the critical debate about curatorial practices and the recovery of Indigenous peoples’ cultural practices and explores how museums can be transformed into cultural centres that “decolonise” their objects while simultaneously providing social agency to marginalised groups such as the San. Indigenous MuseumTraditional methods of displaying Indigenous heritage are now regarded with deep suspicion and resentment by Indigenous peoples (Simpson). A number of related issues such as the appropriation, ownership and repatriation of culture together with the treatment of sensitive and sacred materials and the stereotyping of Indigenous peoples’ identity (Carter; Simpson) have been identified as the main problems in the debate about museum curatorship and Indigenous heritage. The poignant question remains whether the concept of a classical museum—in the sense of how it continues to classify, value and display non-Western artworks—will ever be able to provide agency to Indigenous peoples as long as “their lives are reduced to an abstract set of largely arbitrary material items displayed without much sense of meaning” (Stanley 3). Indeed, as Salvador has argued, no matter how much Indigenous peoples have been involved in the planning and implementation of an exhibition, some issues remain problematic. First, there is the problem of representation: who speaks for the group; who should make decisions and under what circumstances; when is it acceptable for “outsiders” to be involved? Furthermore, Salvador raises another area of contestation and that is the issue of intention. As we agree with Salvador, no matter how good the intention to include Indigenous peoples in the curatorial practices, the fact that Indigenous peoples may have a (political) perspective about the exhibition that differs from the ideological foundation of the museum enterprise, is, indeed, a challenge that must not be overlooked in the discussion of the inclusive museum. This relates to, arguably, one of the most important challenges in respect to the concept of an Indigenous museum: how to present the past and present without creating an essentialising “Other”? As Stanley summarises, the modernising agenda of the museum, including those museums that claim to be Indigenous museums, continues to be heavily embedded in the belief that traditional cultural beliefs, practices and material manifestations must be saved. In other words, exhibitions focusing on Indigenous peoples fail to show them as dynamic, living cultures (Simpson). This raises the issue that museums recreate the past (Sepúlveda dos Santos) while Indigenous peoples’ interests can be best described “in terms of contemporaneity” (Bolton qtd. in Stanley 7). According to Bolton, Indigenous peoples’ interest in museums can be best understood in terms of using these (historical) collections and institutions to address contemporary issues. Or, as Sepúlveda dos Santos argues, in order for museums to be a true place of memory—or indeed a true place of recovery—it is important that the museum makes the link between the past and contemporary issues or to use its objects in such a way that these objects emphasize “the persistence of lived experiences transmitted through generations” (29). Under pressure from Indigenous rights movements, the major aim of some museums is now reconciliation with Indigenous peoples which, ultimately, should result in the return of the cultural objects to the originators of these objects (Kelly and Gordon). Using the Native American Graves Protection and Repatriation Act of 1990 (NAGPRA) as an illustration, we argue that the whole debate of returning or recovering Indigenous peoples’ cultural objects to the original source is still embedded in a discourse that emphasises the mummified aspect of these materials. As Harding argues, NAGPRA is provoking an image of “native Americans as mere passive recipients of their cultural identity, beholden to their ancestors and the museum community for the re-creation of their cultures” (137) when it defines cultural patrimony as objects having ongoing historical, traditional or cultural importance, central to the Native American group or culture itself. According to Harding (2005) NAGPRA’s dominating narrative focuses on the loss, alienation and cultural genocide of the objects as long as these are not returned to their originators. The recovery or the return of the objects to their “original” culture has been applauded as one of the most liberating and emancipatory events in recent years for Indigenous peoples. However, as we have argued elsewhere, the process of recovery needs to do more than just smother the object in its past; recovery can only happen when heritage or tradition is connected to the experience of everyday life. One way of achieving this is to move away from the objectification of Indigenous peoples’ cultures. ObjectificationIn our exploratory enquiry about new museum practices our attention was drawn to a recent debate about ownership and personhood within the context of museology (Busse; Baker; Herle; Bell; Geismar). Busse, in particular, makes the point that in order to reformulate curatorial practices it is important to redefine the concept and meaning of objects. While the above authors do not question the importance of the objects, they all argue that the real importance does not lie in the objects themselves but in the way these objects embody the physical manifestation of social relations. The whole idea that objects matter because they have agency and efficacy, and as such become a kind of person, draws upon recent anthropological theorising by Gell and Strathern. Furthermore, we have not only been inspired by Gell’s and Strathern’s approaches that suggests that objects are social persons, we have also been influenced by Appadurai’s and Kopytoff’s defining of objects as biographical agents and therefore valued because of the associations they have acquired throughout time. We argue that by framing objects in a social network throughout its lifecycle we can avoid the recurrent pitfalls of essentialising objects in terms of their “primitive” or “traditional” (aesthetic) qualities and mystifying the identity of Indigenous peoples as “noble savages.” Focusing more on the social network that surrounds a particular object opens up new avenues of enquiry as to how, and to what extent, museums can become more inclusive vis-à-vis Indigenous peoples. It allows moving beyond the current discourse that approaches the history of the (ethnographic) museum from only one dominant perspective. By tracing an artwork throughout its lifecycle a new metaphor can be discovered; one that shows that Indigenous peoples have not always been victims, but maybe more importantly it allows us to show a more complex narrative of the object itself. It gives us the space to counterweight some of the discourses that have steeped Indigenous artworks in a “postcolonial” framework of sacredness and mythical meaning. This is not to argue that it is not important to be reminded of the dangers of appropriating other cultures’ heritage, but we would argue that it is equally important to show that approaching a story from a one-sided perspective will create a dualism (Bush) and reducing the differences between different cultures to a dualistic opposition fails to recognise the fundamental areas of agency (Morphy). In order for museums to enliven and engage with objects, they must become institutions that emphasise a relational approach towards displaying and curating objects. In the next part of this paper we will explore to what extent an online museum could progressively facilitate the process of providing agency to the social relations that link objects, persons, environments and memories. As Solanilla argues, what has been described as cybermuseology may further transform the museum landscape and provide an opportunity to challenge some of the problems identified above (e.g. essentialising practices). Or to quote the museologist Langlais: “The communication and interaction possibilities offered by the Web to layer information and to allow exploration of multiple meanings are only starting to be exploited. In this context, cybermuseology is known as a practice that is knowledge-driven rather than object-driven, and its main goal is to disseminate knowledge using the interaction possibilities of Information Communication Technologies” (Langlais qtd. in Solanilla 108). One thing which shows promise and merits further exploration is the idea of transforming the act of exhibiting ethnographic objects accompanied by texts and graphics into an act of cyber discourse that allows Indigenous peoples through their own voices and gestures to involve us in their own history. This is particularly the case since Indigenous peoples are using technologies, such as the Internet, as a new medium through which they can recuperate their histories, land rights, knowledge and cultural heritage (Zimmerman et al.). As such, new technology has played a significant role in the contestation and formation of Indigenous peoples’ current identity by creating new social and political spaces through visual and narrative cultural praxis (Ginsburg).Online MuseumsIt has been acknowledged for some time that a presence on the Web might mitigate the effects of what has been described as the “unassailable voice” in the recovery process undertaken by museums (Walsh 77). However, a museum’s online engagement with an Indigenous culture may have significance beyond undercutting the univocal authority of a museum. In the case of the South African National Gallery it was charged with challenging the extent to which it represents entrenched but unacceptable political ideologies. Online museums may provide opportunities in the conservation and dissemination of “life stories” that give an account of an Indigenous culture as it is experienced (Solanilla 105). We argue that in engaging with Indigenous cultural heritage a distinction needs to be drawn between data and the cognitive capacity to learn, “which enables us to extrapolate and learn new knowledge” (Langlois 74). The problem is that access to data about an Indigenous culture does not necessarily lead to an understanding of its knowledge. It has been argued that cybermuseology loses the essential interpersonal element that needs to be present if intangible heritage is understood as “the process of making sense that is generally transmitted orally and through face-to-face experience” (Langlois 78). We agree that the online museum does not enable a reality to be reproduced (Langlois 78).This does not mean that cybermuseology should be dismissed. Instead it provides the opportunity to construct a valuable, but completely new, experience of cultural knowledge (Langlois 78). The technology employed in cybermuseology provides the means by which control over meaning may, at least to some extent, be dispersed (Langlois 78). In this way online museums provide the opportunity for Indigenous peoples to challenge being subjected to manipulation by one authoritative museological voice. One of the ways this may be achieved is through interactivity by enabling the use of social tagging and folksonomy (Solanilla 110; Trant 2). In these processes keywords (tags) are supplied and shared by visitors as a means of accessing museum content. These tags in turn give rise to a classification system (folksonomy). In the context of an online museum engaging with an Indigenous culture we have reservations about the undifferentiated interactivity on the part of all visitors. This issue may be investigated further by examining how interactivity relates to communication. Arguably, an online museum is engaged in communicating Indigenous cultural heritage because it helps to keep it alive and pass it on to others (Langlois 77). However, enabling all visitors to structure online access to that culture may be detrimental to the communication of knowledge that might otherwise occur. The narratives by which Indigenous cultures, rather than visitors, order access to information about their cultures may lead to the communication of important knowledge. An illustration of the potential of this approach is the work Sharon Daniel has been involved with, which enables communities to “produce knowledge and interpret their own experience using media and information technologies” (Daniel, Palabras) partly by means of generating folksonomies. One way in which such issues may be engaged with in the context of online museums is through the argument that database and narrative in such new media objects are opposed to each other (Manovich, New Media 225). A new media work such as an online museum may be understood to be comprised of a database and an interface to that database. A visitor to an online museum may only move through the content of the database by following those paths that have been enabled by those who created the museum (Manovich, New Media 227). In short it is by means of the interface provided to the viewer that the content of the database is structured into a narrative (Manovich, New Media: 226). It is possible to understand online museums as constructions in which narrative and database aspects are emphasized to varying degrees for users. There are a variety of museum projects in which the importance of the interface in creating a narrative interface has been acknowledged. Goldblum et al. describe three examples of websites in which interfaces may be understood as, and explicitly designed for, carrying meaning as well as enabling interactivity: Life after the Holocaust; Ripples of Genocide; and Yearbook 2006.As with these examples, we suggest that it is important there be an explicit engagement with the significance of interface(s) for online museums about Indigenous peoples. The means by which visitors access content is important not only for the way in which visitors interact with material, but also as to what is communicated about, culture. It has been suggested that the curator’s role should be moved away from expertly representing knowledge toward that of assisting people outside the museum to make “authored statements” within it (Bennett 11). In this regard it seems to us that involvement of Indigenous peoples with the construction of the interface(s) to online museums is of considerable significance. Pieterse suggests that ethnographic museums should be guided by a process of self-representation by the “others” portrayed (Pieterse 133). Moreover it should not be forgotten that, because of the separation of content and interface, it is possible to have access to a database of material through more than one interface (Manovich, New Media 226-7). Online museums provide a means by which the artificial homogenization of Indigenous peoples may be challenged.We regard an important potential benefit of an online museum as the replacement of accessing material through the “unassailable voice” with the multiplicity of Indigenous voices. A number of ways to do this are suggested by a variety of new media artworks, including those that employ a database to rearrange information to reveal underlying cultural positions (Paul 100). Paul discusses the work of, amongst others, George Legrady. She describes how it engages with the archive and database as sites that record culture (104-6). Paul specifically discusses Legrady’s work Slippery Traces. This involved viewers navigating through more than 240 postcards. Viewers of work were invited to “first chose one of three quotes appearing on the screen, each of which embodies a different perspective—anthropological, colonialist, or media theory—and thus provides an interpretive angle for the experience of the projects” (104-5). In the same way visitors to an online museum could be provided with a choice of possible Indigenous voices by which its collection might be experienced. We are specifically interested in the implications that such approaches have for the way in which online museums could engage with film. Inspired by Basu’s work on reframing ethnographic film, we see the online museum as providing the possibility of a platform to experiment with new media art in order to expose the meta-narrative(s) about the politics of film making. As Basu argues, in order to provoke a feeling of involvement with the viewer, it is important that the viewer becomes aware “of the plurality of alternative readings/navigations that they might have made” (105). As Weinbren has observed, where a fixed narrative pathway has been constructed by a film, digital technology provides a particularly effective means to challenge it. It would be possible to reveal the way in which dominant political interests regarding Indigenous cultures have been asserted, such as for example in the popular film The Gods Must Be Crazy. New media art once again provides some interesting examples of the way ideology, that might otherwise remain unclear, may be exposed. Paul describes the example of Jennifer and Kevin McCoy’s project How I learned. The work restructures a television series Kung Fu by employing “categories such as ‘how I learned about blocking punches,’ ‘how I learned about exploiting workers,’ or ‘how I learned to love the land’” (Paul 103) to reveal in greater clarity, than otherwise might be possible, the cultural stereotypes used in the visual narratives of the program (Paul 102-4). We suggest that such examples suggest the ways in which online museums could work to reveal and explore the existence not only of meta-narratives expressed by museums as a whole, but also the means by which they are realised within existing items held in museum collections.ConclusionWe argue that the agency for such reflective moments between the San, who have been repeatedly misrepresented or underrepresented in exhibitions and films, and multiple audiences, may be enabled through the generation of multiple narratives within online museums. We would like to make the point that, first and foremost, the theory of representation must be fully understood and acknowledged in order to determine whether, and how, modes of online curating are censorious. As such we see online museums having the potential to play a significant role in illuminating for both the San and multiple audiences the way that any form of representation or displaying restricts the meanings that may be recovered about Indigenous peoples.
