Historical archaeology at Cape Denison, Commonwealth Bay, Antarctica
Authors: McGowan Angela 
Published: October 2009

AbstractArchaeological investigations formed part of the conservation work of Project Blizzard in 1985–86 at the site of Mawson's Australasian Antarctic Expedition (1911–14) huts, Cape Denison, Commonwealth Bay. The extent and nature of the archaeological resources are described, and the results of excavations inside the main hut in 1985 are summarized. Excavation stratigraphy is interpreted in the light of the documented post-abandonment history of the site, and used to measure the extent to which human activity inside the hut may be contributing to its deterioration.

Another sterile annual ritual? The United Nations and Antarctica 1987
Authors: Beck Peter J. 
Published: October 2009

AbstractThe UN Secretary-General's third Report of September 1987 provided the background for the fifth annual round of the UN's consideration of the ‘Question of Antarctica’. The First Committee's discussions in November 1987 resulted in the adoption by large majorities of two further UN resolutions in favour of a moratorium on the Antarctic minerals regime negotiations, an enhanced UN role in the operations of the Antarctic Treaty System, and the exclusion of South Africa from Consultative Meetings. On the surface, the session might be dismissed as yet another ‘sterile annual UN ritual’, serving to confirm the international community's lack of consensus about the future management of Antarctica. In reality, the episode, suggesting that the UN/Antarctic relationship may be at the crossroads, offered several points of interest, including increased signs of strain within the Antarctic Treaty System consequent upon the South African issue, and a greater appreciation by the critics of the need to work for change within the framework of the existing Antarctic Treaty regime.

Convention on the Regulation of Antarctic Mineral Resource Activities: a major addition to the Antarctic Treaty System
Authors: Beck Peter J. 
Published: October 2009

AbstractIn June 1988, at the final session of the Fourth Special Antarctic Treaty Consultative Meeting in Wellington, New Zealand, the Convention on the Regulation of Antarctic Mineral Resource Activities (CRAMRA) was adopted, bringing to a successful conclusion six years of negotiations. Christopher Beeby, chairman of the discussions, presented the convention as the most important political development affecting Antarctica since the 1959 treaty, especially as it established the ability of the Antarctic Treaty System to reach an internal accommodation even upon matters raising serious political, legal, environmental and other issues. There remain uncertainties regarding the future development of the Antarctic minerals question; for example, when will the minerals convention and the proposed institutional framework come into effect, will its ratification encourage mining, can the fragile Antarctic environment be adequately protected against mining, how will certain key terms and concepts be defined, and will the regime's operation bring latent tensions to the surface? It is also difficult to predict how other governments will react to the convention, in the light of recent UN resolutions on Antarctica. The convention is perceived within the Antarctic Treaty system as a significant development, but it will be some time before a considered evaluation of the Antarctic Minerals Regime can be conducted.
Mammals of central North Greenland
Authors: Bennike O. , Higgins A. K. , Kelly M. 
Published: October 2009

AbstractCentral North Greenland, an uninhabited and rarely visited region bordering the Arctic Ocean, supports arctic hare, collared lemming, wolf, arctic fox, polar bear, stoat, ringed seal and musk ox. Their distribution and abundance were noted during Geological Survey of Greenland expeditions in 1984–85, which visited virtually all land areas in the region, including nunataks and islands. Bones of reindeer, bearded seal and narwhal were also found. Ringed seal and reindeer are known to have been present in the region by the early Holocene.

Country food consumption during the Norman Wells Project, 1982–1985
Authors: Bone Robert M. 
Published: October 2009

AbstractDuring public hearings before the Norman Wells Project began, fears were expressed that the project would adversely affect consumption of country food. This note examines consumption of country food by native residents living in four communities in the impact zone of the project The proportion of country food in their diet did not diminish over its construction period, and may have increased slightly, mainly because residents maintained normal harvesting despite handicaps caused by the project. Other mitigating factors were that most construction occurred at a predominately non-native centre (Norman Wells), virtually no natives from the three native communities were employed full-time for the duration of the project, and most of their hunting area was well outside the pipeline impact zone.
Spring distribution, size composition and behaviour of krill Euphausia superba in the western Weddell Sea
Authors: Bergström B.I. , Hempel G. , Marschall H.-P. , North A. , Siegel V. , Strömberg J.-O. 
Published: October 2009

AbstractDistribution, size composition and behaviour of Euphausia superba were investigated in the northwestern Weddell Sea (59–63°S, 45–52°W) in October-November 1988 using RMT trawling, SCUBA diving and visual examination of the ice undersurface using a remotely-operated vehicle (ROV). Amounts of krill washed onto the ice during ice-breaking along transects were noted. Juvenile and sub-adult krill were found, often in high numbers, in association with seasonal pack-ice, from the outer marginal ice zone to at least 200 nautical miles [3 50 km] into the closed pack-ice zone. Krill caught with the RMT or observed within or close to the ice usually had full guts. They were frequently seen feeding on ice algae, and seemed to concentrate in pressure zones, melting ice and infiltration layers, ie where ice provided both confining crevices and rich algal growth. During twilight numbers of krill increased in open water close to the ice, though ROV observations at night revealed even greater numbers remaining in ice cavities. Direct observations from deck, by divers and by ROV, confirmed that most of the krill population in the uppermost water layer was confined to ice habitats, though in three out of 20 RMT catches krill reached densities of 0.1 nr3 ie normal summer values. ‘Miniswarms’ forming in early November may indicate seasonal transition of at least part of the krill population from winter ice habitat and grazing on ice-algae, to summer pelagic life and filter-feeding on phytoplankton.
Fisheries policy and economic development in Greenland in the 1980s
Authors: Poole Graham 
Published: October 2009

ApstractThis article describes the main characteristics of the Greenlandic economy in the 1980s and the aims of the country's Home Rule Government in regard to fisheries policy and economic development. The strategy adopted by the Home Rule Government is presented and evaluated, in terms both of economic theory and of results. Greenland's problems are similar to those of other developing countries, but intensified by its Arctic location, communications problems, a vulnerable resource base and harsh operating conditions inits fisheries, also by its colonial and post-colonial history which has fuelled aspirations towards a high standard of living and given rise to high import demands. Difficulties encountered point towards a modification of the aims and policies of the government, including adoption of a less ambitious approach, focusing upon satisfying basic social and economic needs, and avoiding the mistakes made by the Danish administration in the 1960s and 1970s, which led to alienation of segments of the population from the process of development.
Status and trends of Adélie penguin populations in the Ross Sea region
Authors: Taylor R. H. , Wilson P. R. , Thomas B. W. 
Published: October 2009

AbstractAerial reconnaissance and photography were used in the Ross Sea sector of Antarctica to determine the breeding locations of Adelie penguinsPygoscelis adeliae, and to count the numbers of nests occupied during the early incubation period. From 1981 to 1987, all islands and sea coasts between 158°E and 175°E were searched, and 11 previously unreported breeding rookeries were discovered. Thirty-eight Adé1ie rookeries are now known from the region, with a total of about 1,082,000 breeding pairs — almost half the world population. Some rookeries were photographed in all, or most, of the seven seasons to study the pattern of natural fluctuations in Adelie populations, and comparisons have been made with earlier counts. Populations at nearly all rookeries have increased in size over the last 10–20 years. Possible reasons for this, and for annual fluctuations in numbers breeding, include seasonal variations in. sea ice and weather conditions, and longer-term climatic change.
CCAMLR and its approaches to management of the krill fishery
Authors: Nicol Stephen 
Published: October 2009

AbstractThe Commission for the Conservation of Antarctic MarineLiving Resources has met annually since 1982, with the task of implementing the Convention on the Conservation of Antarctic Marine Living Resources; the treaty which was designed to manage rationally the exploitation of resources in the Southern Ocean. The central resource of the region is Antarctic krill (Euphausia superba Dana) and despite nine years of meetings the Commission has yet to adopt any conservation measures to protect krill. This article examines the published work of the Commission, seeking to determine how the Commission has dealt with the krill fishery and why it has not yet developed a krill management plan.
Out in the cold: Canada's experimental Inuit relocation to Grise Fiord and Resolute Bay
Authors: Marcus Alan R. 
Published: October 2009

AbstractIn 1953–55 the Canadian government experimentally relocated Inuit (Eskimo) families from the region of Port Harrison (Inukjuak), on Quebec's Ungava peninsula, to Ellesmere and Cornwallis Islands in the Arctic Archipelago. Today Inuit relocatees allege that they were deceived by the government and suffered greatly as a result of the experiment. The government asserts that the relocation was undertaken for humanitarian reasons. The controversy has recently resulted in hearings before a Canadian parliamentary committee on aboriginal affairs and the Human Rights Commission. A study of the relocation issue prepared for the government, known as the ‘Hickling Report’, rejects Inuit claims of mistreatment. In this paper the Hickling report's findings are assessed. Contrary to the report's conclusions, documentation suggests that one of the government's motives for undertaking the relocation pertained to Canadian sovereignty and exercising ‘effective occupation’ of the islands.
Mixing characteristics of submerged and surface wastewater outfalls at McMurdo Station
Authors: Railsback Steven F. 
Published: October 2009

AbstractThe mixing characteristics of the existing surface wastewater discharge and a proposed submerged wastewater outfall at McMurdo Station, Antarctica, are compared. The wastewater is a combination of sanitary sewage and brine from a desalination plant. Dispersion from a proposed submerged (15 m-deep) outfall was simulated using the CORMIX1 computer model. The mixing characteristics of the surface discharge were estimated from visual observations and a conceptual analysis. The wastewater was found to be less dense than ambient seawater. From the submerged outfall, the effluent is predicted to be diluted by ratios ranging from 80:1 to 450:1 between the point of discharge and the point where the effluent plume begins to spread out underneath the sea ice. The variation in dilution depends mostly on tidal current speed, and dilution of the wastewater with desalinator brine is predicted to provide only minor reductions in concentrations of the effluent. The heat content of the discharge plume from a submerged outfall is expected to cause at least partial melting of the sea ice from underneath. A surface discharge provides much less mixing with ambient water before the effluent spreads along tidal cracks and underneath the sea ice. The submerged discharge is expected to confine settleable wastewater solids to a benthic area near the outfall, but a surface discharge allows solids to settle over a wider area.
Assessing trends in Arctic sea-ice distribution in the Barents and Kara seas using the Kosmos–Okean satellite series

Published: October 2009

AbstractTrends in the annual minimum sea-ice extent, determined by three criteria (absolute annual minimum, minimum monthly mean, and the extent at the end of August), were investigated for the Barents and western Kara seas and adjacent parts of the Arctic Ocean during 1984–1993. Four definitions of ice extent were examined, based on thresholds of ice concentration: >90%, >70%, >40%, and >10% (El, E2, E3, and E4, respectively). Trends were studied using ice maps produced by the Russian Hydro-Meteorological Service, Kosmos and Okean satellite imagery, and data extracted from published literature. During 1984–1993, an increasing trend in the extent of minimum sea-ice cover was observed in the Barents, Kara, and combined Barents–Kara seas, for all ice-extent definitions. Root-mean-square differences between hydro-meteorological ice maps and satellite-image ice classifications for coincident areas and dates were 15.5%, 19.3%, 18.8%, and 11.5%, for ice extensions El–E4, respectively. The differences were subjected to Monte Carlo analyses to construct confidence intervals for the 10-year ice-map trends. With probability p = 0.8, the average 10-year increase in the minimum monthly mean sea-ice extent (followed in brackets by the average increase in the absolute annual minimum ice extent) was 12–46% [26–96%], 31–71% [55–140%], 30–69% [26–94%], and 48–94% [35–108%] in the Barents Sea; 20–60% [32–120%], 10–45% [20–92%], 2–36% [13–78%], and 10–47% [8–69%] in the Kara Sea; and 9–43% [26–59%], 9–41% [30–63%], 8–41% [22–52%] and 15–51% [21–51%] in the combined Barents–Kara seas, for ice concentrations El–E4, respectively. Including published data from 1966–1983, the trend in minimum monthly mean sea-ice extent for the combined 28-year period showed an average reduction of 8% in the Barents Sea and a 55% reduction in the western Kara Sea; ice extent at the end of August showed an average reduction of 33% in the Barents Sea.
Sea-ice type classification from ERS-1 SAR data based on grey level and texture information
Authors: Smith D.M. , Barrett E.C. , Scott J.C. 
Published: October 2009

AbstractThis paper describes the development of a practical algorithm for the classification of sea-ice types from ERS-1 synthetic aperture radar (SAR) data. The algorithm was based on a combination of grey level and texture information in order to overcome ambiguous grey level values of different ice types. The problem of calculating texture parameters for windows containing more than one ice type was overcome by first segmenting the image so that only pixels from the same segment were included in the calculation of the texture measure. The segmentation procedure was based on the iterative application of a speckle noise reduction filter, and was thus crucially dependent on the ability of such a filter to smooth out noise without destroying edges and fine features. In order to achieve this, a modification to the sigma filter of Lee (1983b) was developed; it out-performed the sigma filter for a model problem. Two ERS-1 SAR scenes of the marginal ice zone east of Spitsbergen in March 1992 were analysed by calculating values of grey level and range for different ice types contained within raw data extracts. Although the grey levels of some of the ice types overlapped, most of the ambiguity was removed through the additional use of range. It was also necessary to test for the wave-like appearance of open water. The classification scheme was demonstrated to identify correctly most of the grease/new ice, first-year ice, multiyear ice, rough ice, pancake ice, and open water in the two SAR scenes, although there was some misclassification of open water as first-year ice.
Last glaciation of Vestfold Hills: extension of the East Antarctic ice sheet or lateral expansion of Sørsdal Glacier?
Authors: Gore D.B. 
Published: October 2009

AbstractOpinions are divided as to whether the area of Vestfold Hills was formerly covered by the East Antarctic ice sheet or S0rsdal Glacier. Striae orientations have been used to erect the model of extension of the ice sheet followed by a minor lateral expansion of Sørsdal Glacier, while basal till fabrics; distribution of weathered rock; and the nature, orientation, and distribution of moraines have been used to conclude that lateral expansion of Sørsdal Glacier alone can explain the evidence of the last glaciation of Vestfold Hills. A review of all available data supports the model of regional glaciation by an extended East Antarctic ice sheet. Lateral expansion of Sørsdal Glacier has probably only played a minor role in the glaciation of Vestfold Hills since the regional glaciation.
Radiocarbon dates of snow petrel (Pagodroma nivea) nest sites in central Dronning Maud Land, Antarctica
Authors: Steele W.K. , Hiller A. 
Published: October 2009

AbstractThis paper presents the results of a radiocarbon dating study of snow petrel (Pagodroma nivea) nest sites in central Dronning Maud Land, Antarctica. Mumiyo (a sub-fossilized accumulation of regurgitated proventricular oil) samples were collected from 15 snow petrel nest sites at nunataks in the northern Ahlmannryggen, Gjelsvikfjella, and Mühlig-Hofmannfjella.Radiocarbon dating revealed Holocene ages of ca 8500 years and less for all but one of these mumiyo samples. A sample collected at S varthamaren in the Muhlig-Hofmannfjella was dated as old as ca 34,000 a BP, indicating that at least some areas of that mountain escaped the scouring action of glaciers during the last glacial period. Similar pre-Holocene ages have been determined for a small number of mumiyo samples in previous studies. Mumiyo accumulations from some nests indicate periods of occupation as long as 6000 years, whereas the radiocarbon age and volume of other mumiyo samples suggest short periods of frequent nesting activity. As expected, sub-samples extracted from the lower layers of mumiyo pieces generally displayed greater ages than sub-samples from upper layers of the same piece. However, there was no clear-cut correlation between the age of a mumiyo sample and its height above the present ice level. It is suspected that this lack of correlation is due to some of the mumiyo samples being displaced previously through rockfalls.
Profiles of national Antarctic operating agencies of Antarctic Treaty Consultative Parties: an introductory study
Authors: Dey-Nuttall Anita 
Published: October 2009

AbstractEach Antarctic Treaty Consultative Party established its national Antarctic operating agency in circumstances that were unique to itself. For some of the original members of the Antarctic Treaty, the initial organisations have continued to act as their national Antarctic operators. New members have either delegated responsibility to existing government organisations or have established new bodies to implement their national Antarctic programmes. The organisations selected to assume responsibility for operating the individual national Antarctic programmes, although varied, possess similar attributes and fall into four categories. Thedistinguishing features of these categories are based on the extent of the functions and financial responsibilities adopted by the agencies. By establishing their nature, this study offers a framework for analysis and a basis for further research on the styles and trends in organising national Antarctic programmes.
Searching for Franklin from Australia: William Parker Snow's initiative of 1853
Authors: Barr William 
Published: October 2009

AbstractIn 1853 William Parker Snow (who had earlier participated in an expedition to search for the missing Franklin expedition in what is now the Canadian Arctic) decided to sink the money he had made in Melbourne during the Australian gold rush into a private expedition to search for Franklin, starting from Melbourne. In the southern autumn of 1853, he bought a 16-ton cutter, The Thomas, and, despite the handicaps of exorbitant prices and shortage of labour, fitted the vessel out for an Arctic expedition during the continuing frenzy of the gold rush. After calling at Sydney, The Thomas started north but encountered a series of violent winter gales that damaged her severely and forced Snow to seek shelter in the mouth of the Clarence River in northeastern New South Wales. By the time the storm damage had been repaired, all but two of Snow's men had deserted. Still in hopes of trying again, Snow sailed his cutter back south to Sydney and there finally abandoned this, one of the more bizarre episodes of the Franklin search.
The Antarctic paintings of Edward Seago (1910–1974)
Authors: Codling Rosamunde 
Published: October 2009

AbstractThe professional artist Edward Seago (1910–1974) travelled to the Antarctic Peninsula, the Falkland Islands, and South Georgia in the 1956/57 austral summer. Although firmly rooted in the English, and in particular the East Anglian, tradition of landscape painting, Seago was able to portray polar landscapes, which he had not previously experienced, with vigour and delight. He went to Antarctica with a firmly established skill in using oils to capture the essence of a landscape, and, despite being on or near the Antarctic Peninsula for only about three days, he produced about 18 oil paintings, predominantly of landscapes and icescapes. In addition, he painted at least a further 17 works of the Falkland Islands, South Georgia, the whaling industry, and icebergs in the Southern Ocean. Seago had an excellent memory and was able to ‘reproduce’ earlier works, an ability that has caused some confusion. Examples of these counterparts are discussed. A catalogue of his known Antarctic works is given.
